摘要:Current conditions of food products market require expanding the range of frozen semi-finished products in particular. However, manufacturers face the problem of the maximum preservation of frozen foods original properties and nutritional value. The paper considers the issues of improving of scientific knowledge about the foods quality formation during preservation by freezing, which will help to achieve a minimum area of temperature kinetics hysteresis, i.e. to achieve thermal reversibility of freezing-unfreezing processes. For this purpose, it was proposed to use various methods of products technological processing before freezing and to control its Мcw parameter which characterizes the proportion of the mass of dry substances and moles of unfrozen water. on the example of red beet and fresh berries which were processed before freezing, the system of their quality evaluation was developed. Conducting a set of researches is promising for compiling similar systems for the assortment of frozen products and some of its types.
