Investigation of the Respiration Rate During Storage of Fruit Vegetables Under the Influence of Abiotic Factors

The aim of the work was to establish the influence of most important abiotic planting factors (temperature, precipitation quantity) on the respiratory rate of fruit vegetables at storage and also a possibility of correction of respiratory metabolism by post-harvest thermal processing by antioxidant compositions. Fruits of cucumbers of the hybrids Masha and Afina, bush pumpkins Kavili and Tamino, sweet pepper of the hybrids Nikita and Hercules, tomato of the varieties Novachok and Rio Grande Original were used for the studies. It was established, that the respiratory rate of pumpkin fruit vegetables is importantly influenced by the variety specificity. The respiratory level of pumpkin vegetables directly correlates with the sum of active temperatures of the period of fruits formation and reversibly – with precipitation and hydrothermal coefficient.The influence of the variety specificity for nightshade vegetables is leveled, and among meteorological planting conditions the important intense influence on the respiratory rate is realized by the sum of active temperatures of the period of fruits formation and ripening. Precipitation and hydrothermal coefficient have the important influence only on pepper fruits.It was established, that the use of post-harvest thermal processing by antioxidant compositions results in inhibition of respiratory processes in fruit vegetables at storage

Development of Innovative TECHNOLOGY for Sauce with Lecithin

Consumers of catering establishments especially value their health and therefore give preference to dishes that correspond to modern concepts of healthy eating. In this regard, the development of such dishes is an important task. Thus, the object of the study was an emulsion sauce made using the spherification technique. Agar-agar was used as a material for encapsulating the sauce. The recipe composition of the sauce contains irreplaceable nutritional components: plant phospholipids (soy lecithin), monounsaturated and polyunsaturated fatty acids of olive oil and camelina oil, natural food fibers of agar-agar. Each recipe component of the developed emulsion sauce contains physiologically active substances with a high efficiency of health-improving effect. Synergy The combination of the positive effects of these prescription components makes it possible to create a therapeutic and prophylactic product. One of the most problematic areas is the formation of a lecithin-oil-water composition with a lamellar structure. Such a structure as a multilayer «container» helps to preserve the biologically active substances that make up the sauce from destruction and to better assimilate them by the human body. Due to the choice of a certain number of recipe components and their sequential combination under certain conditions (temperature 45 °C, mixing), it is possible to obtain a lamellar structure. In the course of the study, recipe components were selected that correspond to healthy food products, recipes and technologies for the preparation of an emulsion sauce with a lamellar structure were developed. And also provided with the help of spherification an attractive appearance and determined the organoleptic, microbiological indicators and shelf life of the product. To confirm the presence of the lamellar structure of the sauce, carry out optical studies and presented a micrograph in polarizing light. The research carried out makes it possible to expand the range of sauces with an extended shelf life (three days) for the restaurant industry
