Protein Raw Material - Cotton Meal

Cottonseed cake and meal are by-products of cottonseed oil extraction. The cake after pressing and extracting oil is called cake, and the meal after pre pressing or direct extraction is called meal. The by-products of extracting oil from cottonseed after dehulling are called cottonseed cake and meal.

The nutritional value of cottonseed cake and meal varies greatly, making a huge difference. The main factors affecting the nutritional value of cottonseed cake and meal are the degree of dehulling of cottonseed and the method of oil production. The crude protein content of cottonseed cake and meal made from completely shelled cottonseed can reach as high as 40%, or even as high as 44%, which is comparable to that of soybean cake; However, the crude fiber content of cottonseed cake produced by directly pressing non shelled cottonseed oil is only 16% -20%, and the crude protein content is only 20% -30%. However, different oil extraction methods have certain differences in crude protein content due to the different fat content in cakes and dregs. Generally, cakes have high fat content, high effective energy value, and low crude protein content; The low fat content and effective energy value in the meal result in a high crude protein content; However, the soil pressed cakes produced by small-scale presses or hydraulic methods in rural areas have a high shell content, even without steaming or insufficient steaming, resulting in low oil removal rate, high fat content, high crude fiber content, and low crude protein content.
