Abstract

Fruit-and-berry sauces, especially from wild-type raw material, which is characterized by high content of biologically active substances (BAS), are the important component of nutrition. During the process, some of the useful substances are lost, because the components of the raw material undergo various transformations, which lead to the accumulation of undesirable compounds and cause deterioration of the sensorial characteristics of the finished product. The actual trend is to study the influence of certain technological parameters on the BAS of a particular type of raw material. This work is devoted to the study of the bioflavonoids change as a result of heat treatment in the production of cornel sauce. The content of bioflavonoids in cornel pureе has been determined and the rational technological parameters at which their greatest content is stored are established. Samples of cornel pureе heeated up to 40, 60.80 and 100 ° C for 10 minutes. As a control used not heeated pureе. In pre-prepared alcohol extractors, the content of anthocyanins, catechins, leucoanthyanidins and flavonols by the spectrophotometric method are determined. The negative influence of temperature on all fractions of bioflavonoids has been established. For leucoanticians, losses during heat treatment are 33%, catechins and flavonols up to 43...46% and up to 50% for anthocyanidins. Leucoanticians are the most labile in the heating process.The influence of spices on the preservation of bioflavonoids in cornel sauce was studied. The selected additives (badyan, cardamom in the ratio of 50:50) have a positive effect on cornel sauce. The stabilizing effect of aromatic plant additives in the amount of 0,3...0,5% on the bioflavonoids from berries is explained by their chemical composition and antioxidant properties, which prevents the destruction of BAS, and thus will allow them to be used for improving the technology of sauces from plant raw materials in order to obtain product of high quality with high sensorial characteristics.

Key words: cornel sauce, anthocyanins, catechins, flavonols, leucoanticians
