Khomenko O. The commodity rating of peanuts and improving consumer properties of peanut products.

The thesis is devoted to peanuts commodity evaluation and improving consumer properties of peanut products. The chemical composition of 19 varieties of peanuts grown from the gene pool of plants of Ukraine was investigated comprehensively. Amino acid composition of peanut protein and its biological value were investigated. Fatty acid composition of peanut fat of the varieties investigated is characterized by a high content of unsaturated fatty acids namely oleic (29 ... 59%) and linoleic (26 ... 64%). Quantitative content of steroids in the kernels of peanut beans was investigated. beta-sitosterol is the main component of peanut phytosterols. Varietal specificity of toxic substances accumulation of peanut was established and the method of their reduction was suggested. Priority varieties were identified and quality criteria were developed for selection aimed at their more unequivocal use. The quality of products based on peanut, namely blended oils, pastes and roasted peanuts was improved with the help of merchandise heuristic expertise. Physical-chemical, microbiological characteristics, indicators of food and biological value and safety of new products were comprehensively investigated. Changes in quality indicators of the developed products during storage were determined, guaranteed terms of their storage were established. Normative documents for new products were developed and approved. The research results were introduced in production and educational process.
