Abstract

The world economic crisis has reduced the temps of organic market development all over the world. Nowadays people can not afford expensive organic products. But experts say that richer consumers that used to buy the products with "bio" label will continue to buy them. Experts are also sure that as soon as economic system will be improved, the organic market will grow rapidly. There are a lot of hidden problems, that's why there is not a clear idea of the connection between real costs for agrarians and the price formation at different stages of technological production chain. In Europe, the organic market exists already for 30 years In Ukraine organic market is developing very quickly. More than 40 percent of consumers are ready to buy free range products for higher prices. However, Ukrainian producers can not meet the demand for "healthy food". As a rule organic milk is produced mainly by the small family farms without antibiotics, synthetic hormones, pesticides or growth stimulants. The animals are kept humanely, they graze on certified pastures, and they consume only certified organic feeds of plant origin. The production of organic products is determined by such three parameters as environmentally friendly raw materials, organic ingredientsand technological process. That's why organic farming has such environmental advantages as reduced carbon emissions, nitrous oxide and methane. Annual certification, periodical inspection and suitable labeling provide conformity of organic products to strict organic standards. All the production stages of milk products are strictly controlled by certificated bodies. Nowadays the producers have the tasks to expand the product range of dairy products and scientific substantiation of certain manufacturing operations regimes (pasteurization, separation, maturation) without hominization to form usual organoleptic qualities of certain types of organic dairy and fat- containing products for domestic consumers . It is necessary to provide the consumer with foodstuffs based on organic compounds that are useful for human body, have a healthy effect if they are consumed regularly. The level of buyer awareness should be higher; the consumer should be stimulated to buy organic products. It is necessary to expand the presence of healthy food in distribution network of Ukraine. The main problems of organic milk domestic market should be determined. The attention should be concentrated on the formation of market conditions in this area.

Abstract

Milk whey processing based on biosynthesis of yeast microorganisms was studied. The screening of eight strains-microorganisms in nutrient media based on curd, cheese and casein milk wheys was presented. The strain-producer of the microbial protein Debaryomyces h ansenii var hansenii Y-4 (D.h.v.) was selected which showed the greatest activity. The composition and amount of micro- elements necessary to enrich the culture medium for maximal accumulation of biomass was established. The optimal amount of seed material was determined; the influence of various factors of biosynthesis was studied. It has been shown that the selected producer (D.h.v.) is able to process curd, cheese and casein milk wheys with the accumulation of biomass in the range of 30-35 g/dm3 that presents a practical interest; herewith the lactose content is reduced to a concentration of less than 0.5%.

Abstract

The paper presents an analysis of combined minced meat with addition of 5% to 40% of a plant protein preparation instead of the meat part. Based on the experimental data, the structural identification was carried out to find an optimal equation of the least order. Adequate models were built for changes in the moisture binding capacity, fat binding capacity and pH (parabola of the 3rd order) when replacing meat raw material with plant protein preparations. The authors suggest that it is possible to replace 10% of meat raw material with retention of satisfactory physico-chemical and functional technological indicators. The functional structure of the computer system for assessment of an effect of new components in emulsified meat products and prediction of their quality is shown, which includes structural parametric principles as well as structural-mechanical and functional-technological indicators of the initial raw material. It seems to be possible to predict quality of a future product by operating the initial data that characterize the composition and properties of raw material and ingredients, establishing boundary conditions and required levels of individual indicators, and using a system of computer modeling.

Abstract

The article describes the results of development of histologic and immunohistochemical methods of research of meat raw materials and finished products. The aim of work is the development of methodology and the improvement of classical microstructural methods of identification of composition’s components to establish the adulteration of meat products. During the developed immunohistochemical color staining, the identification of soy protein was based on its visualization by means of a chromogen (diaminobenzidine) which gives it a brown color. Only the identified component is exposed to color staining, while other ingredients remain of the same color. This method gives the possibility of using a computer image analysis system for quantitative assessment of the composition of the determined soy proteins in the automatic mode.

Abstract

The goal of the research was to research the influence of feed additive “Betain” on the meat quality of hybrid pigs F1. The scientific experiment was conducted at Ukrainian-Holland Ltd. “Servolyuks geneticists” of Orativ district Vinnytsia region. The hybrids F1 (Large White × Landrace) of piglets counterparts were selected for research. In order to level the energy of piglets’ growth we had an egalitarian period lasted for 15 days. The control group during the egalitarian and basic period consumed the basic died (BD); it is a complete feed of «Trouw Nutrition International» company. The researched groups were additionally fed by various doses of feed additive “Betain”. It was proved that consumption of feed additive by hybrid pigs increases the protein contents by 5,5 %; the total humidity by 0,4 % and connected humidity by 1,4 %. However, the level of fat has decreased by 50,0 %, marbling by 25,8%, caloric by 12,3% and ash by 2,14%. It was proved that feeding pigs by researched preparation caused the increasing of arginine, methionine, histidine, threonine, valine, isoleucine, leucine, lysine, phenylalanine, aspartic acid, glutamine acid, alanine, proline, serine, tyrosine, cysteine and glycine. When we use Betain for pigs feeding increases phosphorus by 3,7 %, calcium by 38,4% magnesium by 12,9 %, iron by 13,9%, zinc by 18,3 %, cobalt by 73,9 %, manganese by 66.6%, copper by 96,7%. The usage of preparation Betain as a part of pigs diet causes the increase of such fat acids in the pig lard as oleic by 1.12%, arachidonic by 0,03%, linoleic by 1,9%, α - linolenic by 0,15%, γ-linolenic by 0,04%, pentadetsylove by 0,01%, margarine and oleic by 0,15% , margarine by 0,61%, stearic by 3,06% and peanut fatty acid by 0,02%.
