The Chemical Identifier fields include common identification numbers, the NFPA diamond U.S. Department of Transportation hazard labels, and a general description of the chemical. Most cottonseed oil comes from India these days, were cotton crop products are a large export. Cottonseed oil is so pervasive in processed foods that you have a much greater chance to purchase an item which contains GM cottonseed oilin comparison with different cooking oils. Cottonseed oil does find its way into food products like salad dressing, shortenings, fried foods like potato chips, and more without consumers being the wiser. Cottonseed cake remains after oil is extracted from the seeds. 3.2 Cottonseed oil - an analytical evaluation Cottonseed oil is often used as the standard for measuring flavour and odour qualities of other oils. Cottonseed oil is cooking oil from the seeds of cotton plants of various species, mainly Gossypium hirsutum and Gossypium herbaceum, that are grown for cotton fiber, animal feed, and oil.. Cotton seed has a similar structure to other oilseeds such as sunflower seed, having an oil-bearing kernel surrounded by a hard outer hull; in processing, the oil is extracted from the kernel. TABLE II.— Cottonseed oil is a very common ingredient present in many food sources including chips, margarine, mayonnaise, salad oils and dressing, pasta sauces, packed foods, baked and many more. Cottonseed oil has a mild taste. oil did not prove toxic to rats. The information in CAMEO Chemicals comes from a variety of data sources. Side Effects of Cottonseed Oil. The unrefined oil contains toxic substance named gossypol that could not be digested by humans. The hydrogenated cottonseed oil lead to more side effects than natural cottonseed oil. A similar effect has been found in connection with the feeding of cottonseed meal. Some side effects of cottonseed oil are noted such as an elevated risk of cancer, heart disease, reproductive problems and skin inflammation. effect, whereas cottonseed oil had the opposite effect. The result of this experiment has led us to believe that gossypol is the only substance in raw cottonseed possessing marked toxic properties. Abnormally high values for the melting point and for the saturated acid con- tent of .the hog fat were the chief characteristics noted for the cottonseed oil. cottonseed oil's superior quality in terms of total a - tocopherol equivalent over the most of edible oils. This conclusion was indicated in our previous experiments (17), wherein we found that the gossypol extract freed from gossypol was not toxic.
