STUDY OF LOW PRICE BUTTER SAMPLES FOR SOME QUALITY AND SAFETY INDICATORS

QBDIDJ

Abstract

Butter is a food product with a consistently high demand, which is quite easily subject to adulteration. In this regard, close attention is drawn to low-price butter with a cost on the verge of profitability if the manufacturer uses natural cow's milk. A comprehensive study of six samples of butter in the price range from 280 to 500 rubles per 1 kilogram was carried out in order to establish quality and safety indicators. Products of manufacturers from the Republic of Tatarstan and other regions of the Russian Federation were selected for analysis. The absence of residual amounts of organochlorine pesticides (isomers of hexachlorocyclohexane and dichlorodiphenyltrichloroethane and its metabolites), aflatoxin M1, as well as polyketide antibiotics (chlor-, oxy-, tetracycline and doxycycline) within the sensitivity limits of the chromatographic methods used was established in all butter samples. The labeling and packaging were also studied, the organoleptic quality indicators of butter were assessed using a point system and for compliance with the requirements of GOST 32915-2014, and the fatty acid composition was established. According to the organoleptic properties, all the studied samples were identified as "butter". However, during the analysis of the fatty acid composition of the fat phase, it was found that only one sample out of six corresponded to the established values ​​for the composition of milk fat. Two samples are vegetable-cream spreads with a milk fat content of 40.0 and 40.7%. And three samples are vegetable-fat spreads with a complete replacement of milk fat with non-dairy fats.
