Грибова Н. А. и др. Потребительские предпочтения в отношении переработанной… 588 N. А. Gribova, L. G. Eliseevа Consumer preferences in respect of processed fruit and berry products Nowadays fruits, berries and processed products are an indispensable component of the human diet throughout the year. Frozen fruits and berries are widely distributed on the Russian market and are part of the food industry worldwide. Frozen products become popular among consumers for home use due to the minimal cooking time. Consumer evaluation is the most relevant and significant for identifying preferences and evaluating quality products in Russian markets. In this regard, a qualitative analysis of marketing research has been carried out and preferences have been identified according to which criteria consumers buy quick-frozen products. Some methods of sensory analysis have been used (consumer evaluation, the profile method, and pairwise comparison method). The dominant factor in choosing a brand of quick-frozen products is the combination of an acceptable price and quality, and to a lesser extent, the recommendation of acquaintances, the type of packaging and advertising of products. The research is aimed at identifying organoleptic properties that affect the consumer evaluation of the quality of frozen, thawed grapes in comparison with the reference product. Fruits and berries freeze for hours and even minutes, but are stored for a long time. The problem arises in rehydration – the return of the product to its original state, close to fresh natural raw material. The main goal of the research is aimed at identifying some rational method of defrosting, corresponding to organoleptic and consumer properties. With the help of organoleptic evaluation the best ways of defrosting have been identified – the microwave oven and the freezer. These methods allow obtaining thawed foods with the finest quality and identical to natural raw materials. The storage time after defrosting has been revealed: in the microwave oven – 60 min; at the room temperature – 80 min; in the coldstore – 100 min. The obtained information can be useful for consumers, food industry and confectionery manufacturers. Key words: fruit and berry production, consumer evaluation, organoleptic method, grape, thawing.
