title: [The comparative analysis of two methods of an estimation a butter's quality at its long storage and influence of a thistle spotty extracts on a period of storage].
abstract: In of the comparative analysis of definition of butter's quality--method of peroxide number and a method of definition of aldehydes maintenance are received. Data of peroxide number received by the first method, for 7 and 28 days of storage are practically identical, that does not reflect the valid condition of butter quality. Results of the second method adequately reflect a condition of butter's quality and give the chance to confirm about expediency of its use. Entering as an antioxidant of a thistle spotty seeds extract of 0,001% silybin in butter structure which contains 82,5% of fat prolongs term of its storage on 21 days.
