Chemical composition of the green protein concentrate, prepared from various grasses

Abstract

The article presents the researches carried out with the utilization of green mass of lucerne, cereals and motley grass. At the beginning the initial material was analyzed on the content of nutritious substances. Further the green mass was divided into fractions and out of the obtained sap of different kinds of plants a protein green concentrate was prepared which like the initial raw material was preserved with formic and propionic acid at the level of 3 and 5% to the mass. After the preserving of the products they were analyzed chemically. In the work the comparative analysis of the chemical composition of GPC obtained out of lucerne and other grasses is given, which shows that the biggest protein and carotene extracts have been obtained out of lucerne, and that the grass products have been better kept at their preserving with formic acid at the level of 3% to the mass.
