A method for detecting cows' milk added to goats' milk

, : A method for detecting cows' milk added to goats' milk. Scienza e Tecnica Lattiero Casearia 31(2): 139-143

A method proposed for detection of cows' milk added to goats' milk is based on detection of xanthine oxidase, which is present in much greater quantities in cows' milk. The milk sample (0.5 ml) is treated with 1 ml of a solution of vanillin, which is oxidized by xanthine oxidase to vanillic acid. This produces a blue colour when 0.25 ml of 2,6-dibromoquinone-4-chlorimide solution is added.

Background: gamma-Tocopherol is the most abundant form of vitamin E in the US diet, but alpha-tocopherol concentrations are the highest in plasma and tissues. Although plasma and adipose tissue concentrations of alpha-tocopherol have been used as...

The deleterious effects of warm anoxia on the liver are seen to be irreversible if cooling and transplantation (LT) follow immediately after. The aim of our study is to demonstrate that livers subjected to anoxia may be suitable for LT if a period...
