Abstract

The content of selenium and antagonist elements (Cu, As, Zn, Cd, Pb) in natural milk and products of its processing (cottage cheese and cream) in different seasons of the year is determined. It is noted that the greatest amount of selenium and antagonist elements in natural milk is contained in the summer (in the pasture period). The concentration of antagonist elements in milk processing products (cream and curd) is proportional to their content in the milk from which they are made. The content of antagonist elements in curd is much higher than in cream. This indicates that the elements are mainly associated with the protein part of milk.

Summary

Introduction

Усвоение селена в организме зависит от наличия сопутствующих ему элементов. Ряд таких элементов работают в роли антагонистов. Целью данной работы явилось определение валового содержания селена и элементовантагонистов (Cu, As, Zn, Cd, Pb) в натуральном молоке и в продуктах его переработки (творог, сливки). В качестве объектов исследования выбраны натуральное молоко от коров двух колхозов Аургазинского района Республики Башкортостан (Рисунок 1, 2) и продукты его переработки. Проанализировать содержание селена в натуральном молоке и в продуктах его переработки (цельное молоко, творог, сливки); 2.
