EFFECT OF LOW-TEMPERATURE HYGROTHERMAL PROCESSING ON FORMS OF ASSOCIATION OF MOISTURE IN RICE-VEGETABLE MIXTURE WITH HYDROBIONTS

Abstract

Summary. In the catering industry common combination of rice, vegetable raw materials: onion and carrot, and aquatic organisms: fish, squid, which allows you to get a dish with high consumer properties. The article investigated the influence of the amount of water introduced by the ratio of free and bound moisture in food samples obtained using the low temperature thermo-humidity treatment, compared with the control. Found that for all drawing and vegetable mixture with squid, adding water in an amount exceeding 12.0 % of the total weight of the meal increases the mass fraction of free moisture. For rice-vegetable mixture with carp introduction of additional water is not recommended, since the introduction of water even in the amount of 5 % of the total weight of the meal increases the mass fraction of free moisture. The data indicate that the use of low-temperature thermal treatment of the samples humid pre vacuum packaging technology helps to reduce finished product weight loss, due to the amount of free moisture conservation while increasing the mass of bound water that helps to ensure better consistency of the final product, increase the shelf life and exit semis.
