ANALYSIS OF CHLOROPHYLLS IN LOW QUALITY COTTONSEED OIL

This scientific article presents information about the effect of increasing the amount of cotton seed pods on the quality of cotton oils obtained from I-IV cotton seeds. In particular, in the processing of low-grade cotton seed in JSC "Karshi oil-extraction", the pulpiness of the pulp is 4.3-6.0% higher than the usual one, or the degree of crushing of the pulp obtained from low-grade cottonseed is 5.5-6, 5 percent higher. With the introduction of reverse goods, cottonseed bolls are partially reduced, but this has been shown to be insufficient to significantly reduce the bolls of the pressed material. The color of low-quality cottonseed oil was found to be 20-21 red units higher than the color of ordinary (I-II grades) cottonseed oil by 7-8 blue units. Particular attention should be paid to the difference in pigments in the blue units that condense the processes of cleaning the obtained oils with alkali and bleaching with activated adsorbents.
