Abstract

Annotation. Currently, one of the methods of preserving agricultural plant raw materials is drying, which results in long-term preservation of the native properties of the product. Previously conducted studies have shown that preliminary treatment of plant raw materials with ELF EMF has a beneficial effect on the preservation of its physicochemical and microbiological indicators, and the selection of optimal parameters for processing with ELF EMF is an important stage of this process, as a result of which the processing parameters must be selected individually for each product. This is due to several factors. Firstly, different types of vegetables have different structures and compositions of biologically active substances. Secondly, different types of vegetables have different degrees of sensitivity to electromagnetic fields. Thirdly, the use of certain frequencies and field intensities can contribute to more uniform and efficient drying of products, as well as improving the structure and texture of raw materials. The paper presents the results of a study of the effect of preliminary treatment with ELF EMF of table carrots, white cabbage and zucchini of various varieties, zoned in the Krasnodar Territory, on changes in external damage, weight loss, analysis of the loss of such biologically active substances as acids, vitamin C, sugars during storage in provoking conditions. After mathematical processing of the research results, individual optimal parameters of ELF EMF treatment were selected for each variety of the studied vegetable species.
