my country is the largest cotton manufacturer and also consumer on the planet. As a byproduct of cotton, cottonseed has an annual outcome of tens of countless tons. According to the data provided by the National Grain as well as Oils Information Center, my nation’s cottonseed outcome got to 12.4 million heaps in 2009, and also 10.75 million lots in 2010. According to the September 2011 report of the International Cotton Advisory Board, the worldwide cotton usage in 2011/2012 raised somewhat. Cottonseed obtained in cotton handling is mainly made use of for oil production in addition to saving seeds. Based upon a 16% oil return and also a 90% utilization price, 1,785,600 loads and also 1,548,000 tons of cottonseed oil could be produced in 2009 and also 2010, specifically. Furthermore, cottonseed oil can produce 5.58 million heaps and also 4.84 million lots of cottonseed cake. It can additionally create 3.22 million loads as well as 2.795 million lots of cotton seed hulls, as well as 1.116 million heaps and 0.968 million lots of cotton linters. As a result, cottonseed is not only a vital oil source, yet additionally a crucial healthy protein source. In addition, it likewise offers essential resources for the cultivation of edible fungis and light industry and chemical sector.
Cottonseed oil has a big quantity of essential fats, the material of unsaturated fats is close to 80%, as well as the material of linoleic acid is the highest possible (44.0%~ 55.0%). Linoleic acid can properly hinder the increase of cholesterol in the blood, and it additionally contains oleic acid and linolenic acid Unsaturated fats. At the same time, cottonseed oil is abundant in saturated fatty acids, which can be utilized as frying oil, reducing, margarine, as well as additionally as commercial resources for the manufacturing of stearic acid, palmitic acid, glycerin, as well as malonic acid. Cottonseed oil does not consist of trans-fatty acids. Under the circumstances that the use of hydrogenated vegetable oils containing trans-fatty acids is presently limited in Europe, America and also various other countries, cottonseed oil has come to be an all-natural substitute. With the strengthening of low-phenol cotton study as well as the improvement of phenol elimination modern technology, the polished cottonseed oil has great dietary worth and is a top notch edible oil that is beneficial to human wellness. Today, polished cotton oil is just one of the main edible oil ranges in Xinjiang, Shandong as well as other places. It is additionally a fundamental part of edible mixed oil in my country as well as inhabits an essential placement in edible grease. Cottonseed oil is normally utilized in the market to create soap, glycerin, ink, lubricating oil and pesticide solvent. Recently, people have actually paid an increasing number of attention to environmental management. As one of the sustainable oil crops, cottonseed oil has actually additionally been used to prepare biodiesel.

Cottonseed Oil Applications
Cottonseed oil is rich in saturated fatty acids as well as can be made use of as frying oil, shortening, margarine, as well as additionally as industrial raw materials for the manufacturing of stearic acid, palmitic acid, glycerin, and also malonic acid. Cottonseed oil does not consist of trans-fatty acids. Under the situations that making use of hydrogenated vegetable oils including trans-fatty acids is currently restricted in Europe, America and other countries, cottonseed oil has actually come to be a natural replacement. Cottonseed oil has a good preventative effect on some illness, such as: it has a good preventive effect on hypertension, hyperlipidemia and various other conditions, and also can inhibit the surge of cholesterol. Cottonseed oil is typically used in the industry to produce soap, glycerin, ink, lubricating oil and also chemical solvent. In the last few years, individuals have paid a growing number of focus to environmental protection. Cottonseed oil, as one of the eco-friendly oil crops, is additionally made use of to prepare biodiesel; it can also be utilized as raw material oil for leather fatliquoring representatives, and can also change soybean oil to generate epoxides, international nations are much more made use of as edible oil.
Refining of Cottonseed Oil
The acid value of wool cottonseed oil produced from new cottonseeds is generally 5-7 mg/g, while the acid value of wool cottonseed oil produced from old cottonseeds reaches 15-20 mg/g. Wool cottonseed oil also contains more than 2% gossypol as well as phospholipids, sterols, resins, hydrocarbons and pigments. These components must be removed during the refining process, otherwise it will affect the flavor and sensory indicators of cottonseed oil. Especially gossypol and its derivatives are strong chromogenic pigments, which make wool cottonseed oil red to brown. In the above process, alkali refining deacidification and adsorption decolorization are important processes for removing gossypol and pigment. If these two processes fail to effectively remove gossypol, in the subsequent deodorization process, the color will be fixed due to high temperature, resulting in unremovable color in the refined oil. Therefore, the alkali refining deacidification process is the key to remove gossypol. Alkali refining deacidification is to use alkali to neutralize the free fatty acid in crude oil, so that it can form soap and separate it from the oil. Soap has a strong adsorption capacity, it can absorb a certain amount of pigment, protein, phospholipid, mucus and other impurities, and separate and precipitate from the oil together. During this process, free gossypol in cottonseed oil also reacts with alkali to form phenate, which is adsorbed and precipitated by soapstock, thereby removing gossypol in cottonseed oil.
Production Process of Cottonseed Oil
1: Pre-pressing – leaching process
The pre-pressing-extraction process is currently the most used process for the preparation of cottonseed oil. Gossypol is a toxic phenolic pigment unique to cottonseed. According to the different cotton varieties and planting areas, the content of gossypol in cottonseed is 0.15% to 1.8%. In order to lower the toxicity of gossypol, in the existing cottonseed pre-pressing-extraction procedure, the steaming as well as frying of cottonseed mostly utilize high-moisture steaming. In the very first layer of supporting steaming and frying, the wet moisture of the green body gets to 18%. ~ 22%, because of the huge draft of the billet, the phospholipids first absorb water and also condense in the cake, decreasing the possibility of integrating with totally free gossypol. Phenol has low poisoning and also will not affect the feeding worth of cottonseed dish. At the same time, it likewise reduces the deepening of oil shade as well as the web content of complimentary gossypol in petroleum, thus boosting the high quality of petroleum.
2. Extrusion-extrusion process:
Extrusion puffing means that the material is subjected to wet heat treatment in the extrusion puffing machine, and then kneaded, extruded, glued, decompressed and puffed, and then cooled and dried, so that it becomes a material with a certain structure. For example, the starch gelatinization and gelation in the raw cotton kernel body, the protein structure forms a porous and firm granular “cooked body”, and in the subsequent leaching, the permeability of the solvent and the leaching speed are greatly improved. In addition, the density of the extruded material is also significantly higher than that of the green body, thereby increasing the processing capacity of the leaching equipment.
3. Liquid-liquid-solid three-phase extraction oil production and dephenolization process
In order to keep gossypol in a free state, there is no wet heat treatment in the whole process, which is beneficial to the extraction and removal of gossypol by methanol. The protein content of cottonseed protein powder products can reach more than 50% (N×6.25, dry basis), and the residual free gossypol content is less than 0.04%. The total nutrients, digestible energy and metabolizable energy are higher than ordinary cottonseed meal and comparable to soybean meal. Compared with cottonseed raw materials, the preservation rate of lysine and methionine is relatively high. However, in order to ensure that the residual oil rate in the product is low, leaching equipment with a large processing capacity must be used, thereby increasing the production cost; in addition, after leaching with No. 6 solvent, the wet meal is directly removed with methanol to remove gossypol, which makes it difficult to recover the solvent in the leaching solution, and also The loss of the two solvents is increased.
