Abstract

We assessed the quality of fruit and berry raw materials, carried out a physical and chemical analysis of raw materials for the content of harmful substances and compliance with product safety indicators, in particular for the presence of heavy metals and pesticides, in order to determine the possibility of using raw materials to extract target components.

The subject of the research was the cake of fruit and berry crops. It has a high content of useful components and can serve as a secondary raw material in food production.

The normative documents which give an idea of what methods were used to assess the quality and into what stages the work performed on sample preparation can be divided were analyzed. It should be noted that the process of sample preparation is one of the most important stages in the analysis of products, it is on it that the quality of analytical studies of raw materials and the quality of the final food product depend.

The raw materials (cranberry, blueberry, lingonberry and chokeberry cake) were checked for compliance with the regulatory documents for food products (TR TS 021/2011; GOST R 51074-2016; GOST R 51740-2016 and a number of others) for the content of mercury, arsenic, lead and cadmium. The paper presents the results of the analysis for the content of these toxic elements. The investigated samples meet the required standards. The studied cake can be used as a raw material for the extraction of target components and further processing. These research results can be used as base of the applicability of cake in the food industry in the production of encapsulated forms of food supplements.
