INVESTIGATION OF TEMPERATURE REGIME OF BUCKWHEAT GRAIN STORAGE IN SLEEVES

RNSDSO

Abstract

The possibilities of storing buckwheat grains with different humidity and different content of weed admixture in polymer sleeves are considered. The technology of grain storage in the hands is based on storage without access to oxygen in the air. This goal is achieved by the process of respiration of the grain itself and microorganisms, as a result of which oxygen is converted into carbon dioxide. Since the air exchange with the external environment is closed, the grain is preserved in an environment of carbon dioxide, which is an ideal natural preservative. Aerobic microflora dies in the carbon dioxide environment, oxidation reactions slow down, which ensures high-quality storage. The factors that impose restrictions on the use of polymer storage hoses are shown. Such restrictions include the use of grain with a humidity excee­ding the requirements of the ND, as well as a time limit associated with a low ambient temperature, at which grain acquires subzero temperatures. The analysis of grain samples stored in the sleeves allows us to confirm that with an increase in humidity when the grain is cooled below zero degrees, the number of spoiled grains increases. Spoiled grains included those that darken during GTO, these are grains with a loose (white) easily collapsing core when pressed and grains with a vitreous endosperm. Rotten, moldy, brown-colored kernels were not found in any of the stored sleeves.
