Hello dear reader,
The first month of 2010 has passed and here is the FPI Magazine first issue. First of all, I would like to thank all of you who once again confided in us or have decided for the first time to subscribe for the Magazine. Let us stay together for the whole year and let us hope that there will be no hesitations and lapses in our mutual communication, and that the contents of our 64 pages will bring information and benefit for all of you.
For the year to come is loaded with both difficulties and hopes for improvement. Difficulties related to the overcoming of the crisis effects; hope that the first signs of the crisis end appearing in the world will be felt in Bulgaria as well. Because we are not isolated, our economy forms a part of the global one and it naturally reflects every twitch of the global market.
Having that said, for the present year we are expecting a lot of things to happen – to finally uncork the ill-famed operative and other programs I order to give way to fresh investments for both raw material producers and manufacturers… Let’s wish that the so long wanted officials – competent, operative, correct, and doing their job with the quality needed – would be finally found... Let’s wish that the Single Food Control Authority issue would be finally settled… That the men-of-State would finally pay attention to the Industry Organizations Law, in spite of the existence of the Food Law regulating clearly the rights of BAFDI…
We could surely go on with our claims towards the State. But in the end I would like to shift the attention towards ourselves – towards the branch organization mentioned above that must finally find itself and join the forces of everyone engaged in order to protect successfully the industry interests… Because in spite of all the troubles caused by our Southern neighbors, they at least showed us the power of unity and solidarity…
I wish all of you a successful and beneficial year!

Abstract
Blend of soybean grouts and wheat semolina was extruded using a single-screw laboratory extruder “BRABENDER 20 DN“ (Germany) with a screw diameter of 20 mm and a die nozzle diameter of 3 mm, in order to obtain an aquafeed. The effect of the feed moisture content, the die temperature, the screw speed and the degree of compression of the basic screw on the main physical properties of extrudates was investigated. During the experiments, the speed of the dosing screw was fixed at 70 min-1, the temperature in the first zone was 120°Ñ and in the second zone was 160°Ñ.
Keywords: extrusion, fish feed, single screw extruder, modeling, expansion index, pellet durability index
           
Study of the syneresis of the gel in the production of fresh cheese through ultra filtration
Peter Panayotov, PhD, Chief Assistant, UFT, Plovdiv, 26 Maritza Blvd., tel:032 603 877, panayotov_p@yahoo.com

Summary

The use of UF and the consecutive technological processes lead to a slowed syneresis. The pressure influence over the homogenization, which influences the protein hydrophilicity, is known. In order to establish the influence of this parameter over the separation of the serum that results after the coagulation of a mixture of a concentrate, which has been produced through UF of skimmed raw cow milk and cream, the syneresis index has been defined. The study of the syneresis index of the gel showed its dependency on the quantity of the rennet enzyme (DCÅ), the quantity of the calcium ions (DCaCl2) and the homogenizing pressure (Px). The analysis of the received results enables the determination of suitable parameters for the processing and the coagulation of concentrates and mixtures in the production of low fat and semi-fat fresh cheese.
Key words: coagulation, syneresis, ultrafiltration, concentrate, fresh cheese.

Canning Research Institute, Plovdiv-4000.
Abstract
Descriptive analysis was used to determine the sensory characteristics of product ‘lutenitza’. Prospective members of the descriptive panel were recruited from a pool of consumers who had participated in sensory test at the Sensory Analysis Lab in the Cunning Research Institute in Plovdiv. Potential panelists were screened to test their capability in recognizing and distinguishing tastes and aromatic compounds. Eight trained panelists on descriptive analysis of “lutenitza” participated in the panel. A lexicon of descriptive terms that characterizes sensory profiles of the samples was developed by the panelists. The list of attributes with their definitions and references used for each attribute was made up. 
Key words: sensory analysis, descriptive analysis, descriptive panel, training, lutenitza

Hello dear reader,
 
In your hands-you are holding an issue which appears to be quite parti-colored in terms of topics. In fact that is completely natural, having in mind that food processing industry is represented everywhere in our lives and that it can hardly be found a sector in our being which is not in one way or another interweaved with this industry. That is maybe the reason why, in spite of the crisis, the past month is so rich in events that we were unable to include them all in the issue. And it looks quite obvious that the forthcoming months would not be less interesting for those taking care of Bulgarians' table. We will do our best to be at every place where something related to the branch is happening.
Moreover, the most important forum - the FoodTech International Exhibition within the framework of the Plovdiv Spring Fair is coming. Actually that will be the main topic of our next issue. So we would like to invite you to share with us your achievements and potentials, never mind whether you will take part in the Exhibition or not. Because our pages are a constant and intransient forum which can be of use for you in every moment - in order to learn something new or to spread your own news. Do not forget the latter when you are planning the activities aiming your company promotion and the presentations of your products.

Abstract
The nutritional pattern of school kids in Bulgaria has changed during the years of the transition period. Out of their home, school kids usually eat mostly cheap, affordable and unvaried foods, offered in school buffets and fast-food places. Only few of the pupils attend the school canteens. The aim of this study is to establish and evaluate the food consumption of schoolboys and schoolgirls aged 14-19 years. The sample is representative for our country and includes 152 boys and 142 girls, and it is a part of the National monitoring of the dietary intake and anthropometric status of the Bulgarian population, 2004. Pupils are divided into subgroups according to residence – towns/villages, and according to sex – male, female. The “24 hour recall of food consumption in the previous day” method was used to assess for 3 days (2 workdays and 1 holiday) school kids’ nutrition in spring season. Results show that the average daily consumption of milk is insufficient – 149.6g for boys (recomm. 400g) and 175.1g for girls (recomm. 380g), the consumption of cheese is 27.2-29.1g for boys/girls respectively (recommendations 40g for both). The average meat consumption is 75.3g for boys and 70.5g for girls and exceeds the recommendations for 72-56g net weight respectively. The amount of consumed meat products (sausages) is too high – 31.7g for boys and 36.6g for girls (recommendations for 15g for boys and 10g for girls). The average daily consumption of eggs covers the recommendations and is almost identical in boys and girls – 24.1g and 21.4g. The consumption of fish is 20.5g for boys and 6.0g for girls (recomm. for 24g for both), but most than half of the pupils have not consumed any fish during the course of the study. The amount of added fats (43.7g/day and 36.1g/day) is 20-29% higher than the recommended values. The consumption of bread is 202.1g for boys and 131.9g for girls (mostly white bread), pastry (which is a traditional food in our nutritional pattern) is in amounts of 93.6g and 82.4g respectively. The consumption of vegetables is 175.5g for boys and 164.1g for girls and that of fruits is 171.1g and 124.7g respectively (the recommendations of 400g minimal total fruits and vegetables have not been reached). The conclusion is that the nutritional pattern of teenagers in Bulgaria is a misbalanced one and in order to optimize it there is a need for various strategies and activities, specially designed for school kids.
Keywords: school teenagers, consumption, foods, milk, milk products, meat, meat products, fish, eggs, cereals, bread, vegetables, fruits.
             
Impact of The Screw Revolutions And The Throat of The Die Openings on The Quality Parameters of Extrudates
Lubka Danova
Science Institute of Animal Breeding, Kostinbroad
Abstract
Research was carried out to determine the impact of some constructive characteristics of single-screw extruders, such as feed screw revolutions and throat of die openings, on extrudate quality. Test results prove the existence of correlations between the studied parameters, process conditions, the protein dispersibility index (PDI), the expansion index, and extrudate hardness (Te). For the two mixes studied, it was established that the increased velocity of the feed screw brings about an increase in product temperature, a decrease in the PDI, an increase in the expansion index, and a decrease in extrudate hardness, i.e. extrudates become more fragile.
Key words: screw revolutions, throat of die openings, expansion index, extrudate hardness, protein dispersibility index

Abstract
Nutritional disbalances are the main etiological factors for most chronic non-communicable diseases. In order to be healthy, nutrition must provide the human organism with every essential nutrients and the necessary energy in a balanced formula, to answer the demands of metabolism. The paper presents the analysis performed on consumed foods and groups of foods – milk, milk products, meat, fish, eggs, added fats, covering a population sample of 578 adult individuals (19 – 60 years old) differentiated by age, sex and urban/rural residence who have participated in a national epidemiological survey conducted in 2004 in Bulgaria. The data were obtained by the 24-hour recall method and enabled the assessment of average usual dietary intake in spring which is a risky season in our climatic-geographic region. The consumption of meat and meat products varies within ranges 91.2g – 125.6g/per day. Meat products (salami derived in the main from pork) contribute 18.5 – 27.0% from the quantity of the meat foods   and is comparatively high. The consumption of milk is in the range 122g - 165g and of dairy products (cheese) is prevailingly insufficient - 24 – 32g/d. The daily mean fish consumption (15 – 26g) is approaching recommendations, but with very high intragroup variations. Table added fats are overdosed 37 – 40g. In conclusion the authors give particular practical recommendations for optimization of nutritional disbalances – the main etiological factors for most chronic non-communicable diseases.
Keywords: consumption, food, adults, age 19-30, 30-60 years, milk, meat, fish, eggs, added fats.

Hello dear reader,
The worse, the better... This expression would probably sound strange and illogic, but the last International Spring Fair held in Plovdiv is a clear proof for its truthfulness: First – informed on the comparatively less number of exhibitors, the wide public refrained from mass rush into the fairground and the main part of the visitors was formed by professionals with particular interests in the exhibition. Which means that the interest, the meetings and discussions were really business and justified the Fair motto: “We create new opportunities”; Second – in a conversation, an exhibitor told me: “As for my branch, I am the only representative, and it was the first time so many people stopped at my stand aiming at business contacts...” Of course we have to give the full credit to the omnipresent crisis, but the second example proves our correctness shown with the article entitled “The crisis – time for advertisement”, we published a few issues ago. The “FPI” Magazine team is satisfied with its participation at the Fair too, for our stand was frequented by many visitors, which were basically experts – both scientific and practically-oriented, but all people with real interest in the food and drink industry.
As for the Fair, I will stop here; now let’s say a couple of words about the issue you are holding in your hands. As we promised, the herein is the packing and packaging. A topic that is really important and responsible but that appears to remain a little bit at the background in Bulgaria. However we are convinced that the packaging-related problems will become one of the main issues for the food and drink business management. Here I will not explain why; I would only draw your attention at the fact that there is hardly a European State not holding a Best Packaging competition. Not to mention that there is also a global one... So I am sure that our National Best Packaging Competition “Priz Pak” will resurrect and find its worthy place under the sun. When that time comes, we will let you know!
And in our next issue we will try to refresh you with the soft drinks topic in all its variety, the brew, the ice cream and everything which we rely upon in order to chase the summer heat, to get in tone, generally to feel good. If you have what to share in that direction, please feel welcome. We are looking forward to hearing from you!

Summary
Nutritional disbalances are the main etiological factors for most chronic non-communicable diseases. In order to be healthy, nutrition must provide the human organism with every essential nutrients and the necessary energy in a balanced formula, to answer the demands of metabolism. The paper presents the analysis performed on consumed foods and groups of foods from plant origin – cereals, beans, fruits, vegetables, beverages, covering a population sample of 578 adult individuals (19 – 60 years old) differentiated by age, sex and urban/rural residence who have participated in a national epidemiological survey conducted in 2004 in Bulgaria. The data were obtained by the 24-hour recall method and enabled the assessment of average usual dietary intake in spring which is a risky season in our climatic-geographic region. The major source of complex carbohydrates in Bulgarian diet is bread. The revealed mean daily bread consumption of females is 122 – 144g, resp. of males 178 – 189g. The high intake of bakery products (pies, cheese cakes etc.) 21 – 25% from total cereal – consumption, is a substantial source of hidden fats in the diet of Bulgarian population and quite unfavorable. The mean daily intake of vegetables is 175 – 194g and of fruits 103 – 141g. The total consumption of vegetables and fruits (mean per day) is below recommendations of minimum 400g. In conclusion the authors give particular practical recommendations for optimization of nutritional disbalances – the main etiological factors for most chronic non-communicable diseases.
Keywords: consumption, food, adults, age 19-30, 30-60 years, cereals, beans, vegetables, fruits, beverages.

tel: +359 2 868 32 26, å-mail: nmihalkova@abv.bg
Summary
It is presented in this paper laboratory bread baking by the two-phase method with specific oats and barley based additives of high beta-glucans concentration. As a result of the study it has been established that bread of high flavor and technological characteristics can be obtained by adding of oat flour “Mini prim” up to 25% of the total mixture and up to 17% of specific endosperm oat bran. The adding of 28% of barley endosperm bran deteriorates bread quality and further investigations are needed to that effect.

Institute of Cryobiology and Food Technologies, 1407 Sofia, 53 Cherni vrah blvd., tel.: +359 2 868 32 26, e-mail: nmihalkova@abv.bg
 
Summary
The change of β–glucans and protein content in barley varieties of the Dobrudja Agricultural Institute of 2007 and 2008 crop years has been investigated. Changes in the content of β–glucans up to 1% and in the content of protein up to 2% for the two crop years have been established. From the investigated barley varieties with highest content of β–glucans is the variety 166-507c-13 (mean 6,06%), followed by Radul (mean 5,04%), and the results are repeated for both crop years. They are appropriate for producing of β–glucans enriched flours. The remaining varieties are with a lower content of β–glucans and they are a raw material fit for the forage and brewing industries, depending on the variety purpose.

Summary
The major changes in life conditions during the transition period in our country have exerted a great impact on the features of the nutritional pattern of the elderly population. Low income on one hand, respectively the option to choose only cheep foods, and the specific demands of the metabolism in the age of 60-75 years on the other, place this population group at risk of nutritional misbalances, insufficiencies and excesses. The aim of this study is to establish and evaluate the food consumption of the elderly people aged 60-75 years. The sample is representative for our country and includes 228 people – 112 men and 116 women, divided into subgroups according to residence – towns/villages, and according to sex – male, female. The study is cross sectional and it is a part of the National monitoring of the dietary intake and anthropometric status of the Bulgarian population, 2004. The “24 hour recall of food consumption in the previous day” method was used to assess for 3 days (2 workdays and 1 holiday) people’s nutrition in spring season. Results show that the consumption of bread is 192.2g for men and 175.2g for women (incl. full-grain bread – 16.2 – 24.1g), with recommendations for total amounts – 260/200g for men/women. Pastry consumption (a traditional food in our nutritional pattern) is 41.2g for men, 36.1g for women, resp. The consumption of vegetables is 205.8g for men, 192.5g for women, and that of fruits – 110.4g and 112.8g, resp. The recommendations of 400g minimal total amount of fruits and vegetables have not been reached. The average consumption of milk is insufficient – 174.0g for men and 189.3g for women (recomm. - 300g for both), and that of cheese is 31.9-33.2g respectively for men/women (recomm. for 40-30g). The average meat consumption is 66.5g for men and 54.4g for women, which meets the recommendations for 64.0-52.0g net weight, respectively. The amount of consumed meat products (sausages) is too high – 25.4g for men and 19.3g for women (recomm. – 10.0g for both). The average consumption of eggs meets the requirements and is similar in men and women – 23-19.8g (recomm. 15g). The consumption of fish is 20.0g for men and 7.1g for women (recomm. 24-20g for men/women), but more than half of the individuals have not consumed any fish during the course of the study. The amount of added fats (40.2g/day and 34g/day) is 56-70% higher than the recommended values.
The conclusion is that the nutritional pattern of the elderly people aged 60-75 years in Bulgaria is a misbalanced one and in order to optimize it there is a need for various social strategies and programs, specially designed for this population group.
Key words: elderly people, 60-75 years, consumption, foods, milk, milk products, meat, meat products, fish, eggs, cereals, bread, vegetables, fruits.

Abstract
We have proposed means for establishing the economic injury limitation by pests – population density, at which the quantitative damages value has been equalized with the fumigation costs. Simulation models for insect population growth and the losses from the feeding of the most widely spread and harmful pest Sitophilus oryzae (L.) have been composed. By means of simulation results the weight losses (0,074kg/t) have been determined, which have been accumulated at infestation rate growth to 1 insect per kg. On the basis of this value, the moment prices of grain and the costs expected for pest control, the economic injury limitation has been calculated. Population density (8 insect per kg) up to which the fumigation should be carried out has been determined, so that no significant damages by the pests have been admitted.
Key words: pest control, fumigation, action threshold, weight loss, Sitophilus oryzae

Abstract
Experts of nutrition place people at advanced age as population group at risk. Lowered immune responses, slow metabolism, degenerative changes in organs and systems, less activities and concomitant health problems – they all demand for specific requirements of balance and high density for the nutrition of people at advanced age. The aim of this study is to establish and evaluate the food consumption of people at advanced age – beyond 75 years. The sample is representative for our country and includes 195 people – 92 men and 103 women, divided into subgroups according to residence – towns/villages, and according to sex – male, female. The study is cross sectional and it is a part of the National monitoring of the dietary intake and anthropometric status of the Bulgarian population, 2004. The “24 hour recall of food consumption in the previous day” method was used to assess for 3 days (2 workdays and 1 holiday) people’s nutrition in spring season. Results show that the average consumption of cereals is 261.7g for men and 233.0g for women. The relative fraction of bread from the total amount of cereals is 74% for men and 85% for women – it is 194.2g for men and 155.8g for women (incl. full-grain bread 18.8 – 22.4g), with recommendations for total amount of bread 240/190g for men/women. Pastry consumption (a traditional food in our nutritional pattern) is 44.5g for men, 44.7g for women, resp. The consumption of vegetables is almost identical - 158.4g for men, 159.8g for women, as is that of fruits – 109.2g and 125.9g, resp. The recommendations of 400g minimal total amount of fruits and vegetables have not been reached. The average consumption of milk is insufficient – 208.8g for men and 217.0g for women (recomm. - 300g for both), and that of cheese is sufficient - 35.3-30.9g respectively for men/women (recomm. for 35-30g). The average meat consumption is equal for men and women – 44.7-47.8g, with recommendations for 56.0-52.0g net weight, respectively. The amount of consumed meat products (sausages) is too high – 16.4g for men and 10.9g for women (recomm. – 10.0-5.0g, resp.). The average consumption of eggs meets the requirements and is similar in men and women 14.8-12.0g (recomm. 12g). The consumption of fish is insufficient - 9.1g for men and 7.0g for women (recomm. 24-16g for men/women), but more than half of the individuals have not consumed any fish during the course of the study. The amount of added fats is 30.6g/day and 35.5g/day for men/women and is 24-97% higher than the recommended values (24.0-18.0g/day, resp.).
The conclusion is that the nutritional pattern of people at advanced age, beyond 75 years, in Bulgaria is a misbalanced one and in order to optimize it there is a need for special care and social help in the aspect of national and regional interventional programs.
Key words: people at advanced age beyond 75 years, consumption, foods, milk, milk products, meat, meat products, fish, eggs, cereals, bread, vegetables, fruits

Head Assistant Professor Dessislav Balev, PhD,  Professor Stefan Dragoev, DSc.
University of Food Technologies, Plovdiv, Department of Meat and Fish Technology,
 
Summary
The effect of superficial treatment of beef cuts with dihydroquercetin (DHQ), individually or in a combination with packaging under high oxygen modified atmosphere, on the oxidative stability of beef lipids, have been investigated. The conclusion has been done, that in the result of limited antioxidant action the oxidative stability of beef lipids increases. This tendency is the least included after a superficial treatment of beef cuts with spray, containing 1 g DHQ.l-1 in the form of 5 % water solution of ethanol and packaged under air. Contrary to this, the tendency is less included when the beef cuts were superficially treated by spray, containing 1 g DHQ.l-1 in the form of 5 % water solution of ethanol and packaged under modified atmosphere (80 % Î2; 20 % ÑÎ2).
Key words: antioxidants, taxifolin, beef, modified atmosphere, lipid peroxidation

Abstract
Fatty acid composition and triacylglycerol profile of 21 sunflower oils from The Bulgarian Market were investigated. It was established that they corresponded to those of typical sunflower oils and, moreover, the analyzed brands had very similar composition. The oxidation degree of the oils was estimated by determination of the peroxide value and the concentration of conjugated diene structures. The oxidation stability of the oils was determined at 100°C. It was established that the investigated sunflower oils can be characterized as “fresh” oils possessing a good oxidation stability.

Abstract
Dry components of different red and white wines were investigated by application of thin layer nematic liquid crystal. A change in the orientation of optically anisotropic liquid crystal molecules was found out at the border with the wine residue. Differences between the structures of investigated pure wine samples and samples with inclusions are observed. The optical analyses of deformed liquid crystal layer were realized by polarizing microscopy.
The method, presented in this work, gives possibilities for quick detection of wine inclusions. It is convenient also for other drinks (for example tee, coffee) testing.

Abstract
Peroxide and acid number, 2-thiobarbituric acid reactive substances (TBARS), heme iron and nitrosomioglobin are determined into vacuum packed beef jerky (Bulgarian pastirma) during 4 months storage at 4oC.
Significantly increasing of hydroperoxides after the 1-st month of storage is establi-shed. Subsequently they take part into secondary reactions of oxidation
Acid number values are significantly deceasing which is connected with lipid oxida-tion during this period.
The malondialdehyde concentration changes are explained with a possible mechanism of muscle protein denaturation in the production process of jerky. Its values during the entire period of storage are below 1 mg/kg product.
The removing of oxygen at the process of vacuum packaging preserves beef jerky from lipolytic and oxidative processes, resulting into worsening of the final product.
Key words: beef jerky; peroxide number (PN); acid number (AN); 2-thiobarbituric acid reactive substances (TBARS);
