FEATURES OF PROCESSING OF OILS OBTAINED FROM LOW GRADE COTTON SEEDS

This paper presents a technology for refining low-grade cottonseed oil, in which refined high-grade cottonseed oil has a yield of 85% and 12 colors and 35 yellow units in a 13.5 cm layer of Lovibond with 35 yellow units. k units, and the yield of refined oil obtained from low-grade cottonseed is 81.5%, the color is 18 red and 4 blue units, 35 yellow, the refined oil obtained from non-standard cottonseed has a yield of 78.3% and 13 It was found that 35 yellow, 19 red and 5 blue units were found in the .5 cm layer.

Introduction: Along with high-grade cotton seeds, oil and fat enterprises in Uzbekistan annually receive low-grade ones, the amount of which varies between 25-35% (depending on the climatic conditions of the year, etc.) [1, p.44], [2, p.44].

When processing such seeds at enterprises, oils with a high content of free fatty acids, gossypol, chlorophyll and their derivatives are obtained, which negatively affects the quantity of refined oils obtained and their quality. Known technological schemes [3, p.164], [4, p.7]. Refining of oils obtained from low-grade cotton seeds is not effective enough and requires improvement. To develop new technological methods, first of all, it is necessary to study the distinctive features of the qualitative composition of oils obtained from low-grade and non-standard cotton seeds [5, p.23].

We conducted a comparative study of the qualitative composition of black oils obtained from high-grade, low-grade and non-standard cotton seeds under the production conditions of Limited liability company “Asiangolden”. Sampling of black oil was carried out after the filter presses during the normal functioning of the pre-press shop, established in the technological regulations [6, p.471].
