| 释义 |
Cottonseed is the seed of the cotton plant. CompositionThe mature seeds are brown ovoids weighing about a tenth of a gram. By weight, they are 60% cotyledon, 32% coat and 8% embryonic root and shoot. These are 20% protein, 20% oil and 3.5% starch. Fibers grow from the seed coat to form a boll of cotton lint. The boll is a protective fruit and when the plant is grown commercially, it is stripped from the seed by ginning and the lint is then processed into cotton fibre. For unit weight of fibre, about 1.6 units of seeds are produced. The seeds are about 15% of the value of the crop and are pressed to make oil and used as ruminant animal feed. About 5% of the seeds are used for sowing the next crop. Whole cottonseed is another feed product of cottonseed used to feed livestock. It is the seed left after the separation of long fibres from cotton, and serves as a good source of cellulose for ruminants. Whole cottonseed leads to high production of milk and fat when fed to a high-producing dairy cow. It can be cost effective and provides nutrients with a high protein value of about 23%, crude fibre value of 25%, and high energy value of 20%. Whole cottonseed serves as a highly digestible feed which also improves the reproductive performance in livestock. Pima cottonseed, which is free of linters by default, and delinted cottonseed are other types of cottonseed feed products.[8]Cottonseed oilThe refined seed oil extracted from the kernels can be used as a cooking oil or in salad dressings. It is also used in the production of shortening and margarine. Cotton grown for the extraction of cottonseed oil is one of major crops grown around the world for the production of oil, after soy, corn, and canola.{{cn|date=August 2015}} FertilizerThe cottonseed meal after being dried can be used as a dry organic fertilizer, as it contains 41% protein. It can also be mixed with other natural fertilizers to improve its quality and use. Due to its natural nutrients, cottonseed meal improves soil's texture and helps retain moisture. It serves as a good source of natural fertilizers in dry areas due to its tendency of keeping the soil moist. Cottonseed meal and cottonseed ashes are also sometimes used to supplement organic hydroponic solutions.[9] Cottonseed meal fertilizers can be used for roses, camellias, or vegetable gardens.[10] CosmeticsThe fine quality oil extracted from cottonseed during the extraction process is also used in cosmetics, such as moisturizing lotions and bath soaps.
