THE INFLUENCE OF SOUS-VIDE TREATMENT ON THE FORM OF MOISTURE IN LARGE-VEGETABLE MEAT SYSTEMS

The current development of the catering industry is due to the improvement of the processes of heat cooking of raw materials. One such area is the use of low-temperature hydrothermal cooking food, pre-vacuum-packed in heat-resistant polymer film. In cooking, spread a combination of rice, chicken and vegetable ingredients: onions and carrots, which allows you to get a dish with high consumer properties. During the study, it was determined the amount of moisture needed to reach the desired consistency of the mixture components to increase the yield of finished products, while providing maximum storage periods. The results show that the addition of water in amounts exceeding 3.0% of the total weight of food leads to an increase in the mass fraction of free moisture

Protein composition in tofu of corrected quality

Soybeans are an inexpensive, high-quality protein source. Soybeans have long been a staple of the human diet in Asia, especially as tofu, which is prepared from soymilk. In this study, tofu was made using a new production method which includes hydrothermal cooking (HTC) and rennin-pepsin coagulant. The effects of the addition of gallic acid to the slurry during tofu processing were studied. Tofu was made from two soybean genotypes: Lana and Balkan. The observed genotypes are characterized by relatively high content of total proteins in flour, from 45.88% to 48.83%. The prepared tofu samples are characterized by extremely high content of total proteins (52.17% - Lana tofu and 56.08% - Balkan tofu). The presence of gallic acid significantly affects the solubility of tofu protein. The applied modifications of traditional procedure of tofu production significantly improved sensory properties of soybean protein products.
