DEVELOPMENT OF TECHNOLOGY OF SEMI-FINISHED DESSERT PRODUCTS BASED ON DAIRY AND FRUIT-BERRY RAW MATERIALS USING THE PRINCIPLES OF COLLOID STABILIZATION OF MILK

Nataliya Grynchenko

Abstract


There was realized the analysis of priority directions in the production technology of combined products, based on milk and fruit-berry raw materials. It was determined, that the common use of these components is rather limited from the point of view of providing colloid stability of the system without its stratification that is conditioned by the low рН values and influence of high temperatures at pasteurization of products. There was offered the method of milk stabilization at low рН values by decreasing the ionic  calcium content to 40 % of its initial content. It was proved, that the process of milk decalcification by using sodium alginate allows to increase its acid tolerance and thermal tolerance that becomes a precondition  for creating dessert semi-products, based on milk and fruit-berry raw materials. Using methods of the system analysis, there was elaborated the model of the technological system of dessert semi-products, which presents a final product as an integral technological system A, detailed to subsystems D1,…Dn, В, С, according to the developed technological process. There was established an interconnection  between separate subsystems and its elements, studied ways of its functioning at macro- (interaction with the external environment) and micro-levels (study of internal characteristics). There was realized the organoleptic evaluation of the quality of products by the descriptive (qualitative) method and by the method of profile analysis (quantitative one). At that the notion of each organoleptic parameter (consistence, taste, smell and so on) is presented as a totality of components (descriptors), evaluated in the determined order by quality and intensity. The characteristic of organoleptic parameters by scales of intensity of separate signs is presented as profile diagrams. There were determined ways of using semi-products in the composition of dessert products. There was developed the principal technological scheme of their production. There was proved the effectiveness of introducing new products in institutions of restaurant economy and food industry.
