P. 16-19 Key words
nutrition for athletes; proteins; fats; carbohydrates; minerals; and food additives

Specialized food products for athletes' nutrition are a separate group of products with given nutritional and energy value. Special diets, specialized food products and drinks, which consider a kind of sport (including phases of sports activity) and individual peculiarities of an athlete are being worked out. Food ration of athletes is formed to fulfil 55-60?% of daily requirement of energy at the expense of carbohydrates. The analysis was conducted by experts of the Plekhanov Russian University of Economics together with the Moscow State University of Food Production. On average athletes' daily consumption rate of carbohydrates must be 5gr per kilo of body weight. The required amount of energy depends on age, sex, body weight and also on quantity-intensity of trainings ratio. Carbohydrates are especially important for athletes, taking part in such sports disciplines that require great stamina. Proteins are used for athletes in all disciplines to help them recover after loads, increase muscle mass and productivity in power sports. Apart from proteins and carbohydrates vitamin mineral complex, which regulates metabolism in athlete's organism, is also of great importance. Adequate provision of the body with particular vitamins is extremely important for some kinds of sport. Although fats are essential for healthy nutrition, low-fat diets (25-30?%from total amount of consumed calories) are recommended to athletes. Lack of any kind of food products and microelements may be sustained with the help of functional products, which are widely spread on the modern sports nutrition market. Nutrition depending on the kind of sport varies greatly in terms of carbohydrate, protein and lipid orientation. It is necessary to work out food products with their own definite set of components in carbohydrate protein and lipid composition for each group of athletes. It is necessary to organize nutrition individualization in sport of higher achievements. Some sports nutrition classifications have been examined.

Currently world's food producers use traditional materials and also waste from the processing and cutting of the traditional food raw materials. We studied the relation of northern shrimp Pandalus Borealis soft tissues various parts for determining of the prospects of the use of waste produced during the processing of it. It was established experimentally that the waste is of the order of 8?% of the muscle fibers of the total weight of whole shrimp. muscle cephalothorax, of walking and swimming legs slightly, but superior in nutritional value of the abdominal part. The percentage of muscle fibers in the food portion is five times higher than in the waste. According to the content of magnesium, potassium and calcium cephalothorax, swimming and walking legs soft tissues are not inferior to the ventral portion. The high content in the soft tissues of cephalothorax, swimming and walking legs shrimp northern Pandalus Borealis potassium at a relatively low sodium content, as well as the presence of magnesium, molybdenum, selenium, zinc, iodine, copper, shows the prospects of their use as a therapeutic component, therapeutic and preventive and functional foods. It was found that the soft tissues of northern shrimp Pandalus Borealis wastes contain all the essential and nonessential amino acids. The amino acids content in muscle tissue cephalothorax, swimming and walking legs exceeds the abdominal part of the following amino acids: izoleyzin, leucine, valine, and threonine. Soft tissues of northern shrimp Pandalus Borealis wastes are advanced sources of raw materials for modification, products of enrichment and development of functional foods.

The problem of disposal of by-products of modern Corn-starch Russian companies is very serious. By-products Corn-processing plants are dehydrated and boiled pulp extract, containing a large number of organic compounds, the discharge of which has a negative impact on the environment and the environmental situation. The basis of deep processing of corn starch - a recycling and by-products, and organization of a dry food. The work was conducted by Institute of starch products.Pulp - is a granular material consisting of grain shell pieces and scraps of cellulose, of various shapes and sizes. Boiled extract - a thick, viscous liquid with the properties of sticking to the walls of the working bodies and equipment, complicates the process of mixing the feedstuff components with each other. Before applying these products to the drier they must be carefully mixed. For intensive mixing of the two-phase side products: pulp and boiled corn extract developed continuous mixer. Mixing is carried out blades fixed to two horizontal shafts, the angle of inclination relative to the axis can be changed when adjusting the mixing time and the performance of the device. Shafts are immersed in the trough-shaped casing and are rotated in opposite directions by two independent drives - motors. Domestic mixers that meet the technological and technical requirements of the mixing process is not carried out. In existing plants for these purposes, mixers foreign manufacturers.

Frolova Yu.V. The Environmental Component of the Application of the Modified Latex Coating in the Food Industry

P. 44-46 Key words
destruction; latex; nanoparticles; environment; foodstuffs; polymer coatings

The article deals with the ability of the modified coatings which are based on aqueous polymer dispersions with metal nanoparticles and the effect of microorganisms to degrade this kind of material. The effectiveness of combining food packaging and coating with those special properties depends on the presence of antimicrobial additives, antioxidants, fragrances, pigments, and other substances. After using, the packaging and its components must be decomposed without causing harm to the environment. Work performed at the Moscow State University of Food Production. The aim of this research is to study the effect of modifying in the process of degradation of latex coating which contains silver nanoparticles through the influence of microorganisms. The studies were conducted in the laboratory of the Moscow State University of Food Production (MGUFP). The modified latex is subjected to prolong exposure to the fungus Trichoderma viride in the conditions of high humidity (90?%) and the different characteristics of the contaminated material. Determining the degree of development of culture on the surface of the material within 28 days and the change of deformation strength characteristics within 84 days. As a result, it is found that the degree of development of the fungus Trichoderma viride does not affect silver nanoparticles which are contained in the coating. The development of the fungus in the study depends on the characteristics of contaminated coating. The process of degradation of the modified coatings is evaluated by the change of the deformation strength characteristics. It is found that the better development of the fungus, the faster deteriorate of the relational elongation and destroying strain at fractures. Impacting culture within 84 days under the condition of humidity and the presence of minerals and organic substances, modified coating is decomposed. It is found that the nanoparticles silver which are contained in the coating does not prevent the destruction of the modified coating in the environment. The study of the interaction between the material and the fungus suggests that the certain amount of silver nanoparticles which are contained in the coating does not affect the microflora soil. The author believes that the ability of the modified latex coating is destroyed by the fungus Trichoderma viride, it is an advantage when selecting protective polymer coating from a series of similar materials.

Over the last decade an increasing number of toxins that affect the safety of raw materials and food, at the same time increases the time and complicated methods of their determination. A complete analysis of food quality and safety in all normalized indicators rather expensive. In this regard, the current control is an integral security biotesting products. Purpose - to conduct experimental evaluation methods for determining the acute toxicity using cultures of ciliates Tetrahymena pyriformis, raw materials for safety control and food in their monitoring process. Work performed at the Moscow State University of Food Production in conjunction with the All-Russian Research Institute of Veterinary Sanitation, Hygiene and Ecology and "Russian Quality System". The objects of the study served as animal feed (meat of agricultural, wildlife and waterfowl, river fish) and vegetable (green). The results of the evaluation studies bioassay methods for monitoring food safety in their monitoring process. In most cases, it shows the correlation results of toxicity using techniques to determine the acute toxicity of infusoria and also to their content of particular natural and anthropogenic toxicants. In some defective samples observed differences in the reactions of biological testing techniques and methods for the detection and identification of toxic agents. When monitoring of fish, some of the copies were struck vibriosis, tetrahimena - did not react. The meat of wild animals (wild boar, spotted deer, duck), heavy metals were detected by physical and chemical methods, but the method of acute toxicity has not given positive results. Methods of determining the acute toxicity using ciliates sufficient rapidity, does not require the use of test animals or expensive equipment and has prospects for rapid raw material control and safety of food products, however, for its implementation should be carried out to validate the specific objects and man-made or natural toxins.

Mazhidov K.Kh., Sulaymanova G.Kh., Bozorov D.Kh., Sabirova N.N.Methods for the Determination of Solid Fats Fractions in the Fat Emulsion

P. 56-58 Key words
dilatometry; methods of determination; evaluation and analysis methods; fraction of emulsified fat; nuclear magnetic resonance

In the production of fat and margarine determining the amount of solid fat is an important part of the control of production processes. The most widespread dilatometry method based on the fact that in the melting fat is its extension. However, this method is laborious enough requires considerable time. Also, there may be errors in the calculation of the percentage of solid fat based on the amount of bulk deformation. This work is devoted to the evaluation methods for determining the fraction of solid fat in the fat emulsion using dilatometry and nuclear magnetic resonance (NMR). In applying the method dilatometry and broad-line NMR sample was kept at 60 ° C for 30 min before measuring the signal during expansion, then - the signal for molten fat. When using any NMR pulse measurement method at 60 ° C is not required, so the sample is kept at this temperature for a total of 5 minutes in order to melt them. According to the method minispeka can measure the size of very small droplets (0.25 um) solid fractions of fats. This new technique is applicable to NMR individual droplets and their mergers. Advantages NMR method is that without any sample preparation is required, nor its dissolution, do not destroy the sample with the measurement. Use of low resolution NMR technique is not dependent on the color sample surface, the viscosity of the emulsion. From the viewpoint of experimental accuracy and its duration NMR technique has clear advantages in comparison with classical analytical technique that uses extraction methods and dilatometry. The method ensures the accuracy of the result during the two consecutive tests. Using NMR method in determining the composition of the solids in the fat emulsion products is the most appropriate and efficient, allowing to reduce costs for research.
