The safety and quality of vegetable oil depending on the varieties and hybrides of rape grown under the conditions of Ryazan region

The goal was to study qualitative characteristics of spring rape cultivated in Ryazan Region and vegetable oil obtained from the seeds of the culture. The varieties and hybrids of spring rape grown in experimental agrotechnological station of the FSBEI HE of Ryazan Region in 2018-2019 on gray forest loamy soil were used as raw materials for the production and research of vegetable oil. According to the results of the studies, oilseed rape grown in Ryazan Region of the varieties Ratnik, Vikros, Lipetsky and hybrids Ozorno, Salsa KL were recommended to be used as raw material for the production of oil. By the content of important C18:1 oleic acid (60.2-44.5 %) in each test oil sample, and low values were noted in the sum C16:0 palmitic + C18:0 stearic acids (6.4-3.8 %). Foreign hybrids Ozorno, Salsa KL were characterized by high oleic lines, having 3.2 % more in the sum of C18:1n9c oleic acid + C18:1n9 scis oleic acid than in the standard oil of Ratnik variety. According to the content of erucic acid in each specimen there were low values not higher than 0.6 %, in accordance with the permissible requirements as raw materials for a food product. Vegetable oil obtained from rape seeds of all studied varietal samples grown in the conditions of the region according to organoleptic and physical and chemical indicators comply with the requirements of regulatory documents and are a quality product. The resulting oil, in terms of the content of toxic elements and radionuclides, complies with the requirements of regulatory documents and is a safe product.
