О‘simlik yog‘larini qabul qilishda fizik-kimyoviy nazoratlarni olib borishni va ularni sifat kо‘rsatkichlarini tahlil qilish, bunda о‘simlik yog‘i (paxta yog‘i) tarkibida oz miqdorda bо‘lsada, yog‘ning xossalariga ta’sir etadigan fosfatidlar, sterinlar, tokoferollar moyning fizologik qiymatini oshirsada, erkin yog‘ kislotalari, gossipol va uning birikmalari moy sifatini pasaytiradi va buni aniqlash usullari izlab topish uning sifatini oshirish ya’ni erkin yog‘ kislotalar sonini kamaytirish bugunning dolzarb muammolaridan biri xisoblanadi. Paxta yog‘ining tarkibida gossipol moddasi bor. Yog‘ zavodlari gossipolni tozalashda, lekin u ma’lum miqdorda yog‘ tarkibida doimo qolaveradi. Zarari shundaki jigar о‘sha zaharli moddani о‘zida ushlab qoladi va jigar zaharlanish kasalligining turli xil formalari kelib chiqaveradi. Shunga kо‘ra mazkur ish davomida paxta yog‘i tarkibidagi namlik va uchuvchan moddalar miqdori, yog‘ bо‘lmagan moddalar miqdori, xuddi shuningdek yog‘larning kislota soni ham aniqlandi.
Physical and chemical control of vegetable oils and their analysis of quality indicators, including phosphatides, sterols, tocopherols, which affect the properties of the oil, even in small amounts in vegetable oil (cottonseed oil), increase the physiological value of the oil, free fatty acids, gossypol and its compounds reduce the quality of fat, and finding ways to determine this is one of the most pressing issues today to improve its quality i.e. reduce the number of free fatty acids. Cottonseed oil contains gossypol. Although oil refineries purify gossypol, it still retains a certain amount of fat content. The disadvantage is that the liver retains that toxin and various forms of hepatitis can develop. Therefore, during this work, the content of moisture and volatile substances in cottonseed oil, the amount of non-fatty substances, as well as the acid number of oils were determined.
