It is rich in Vitamin-E which act as antioxidants and Resists mold growth in food, which gives the product a longer shelf life. It is known as a “naturally hydrogenated oil” as it contains sufficient natural palmitic, stearic and Myristic acids. Due to the presence of unsaturated oleic, linoleic and linolenic fatty acids it is also known as a “Heart Healthy Oil”, Cottonseed oil has also gained importance in food preparations due to its higher smoke point (about 230 C) compared to other oils and is good for frying food articles like frying potato and corn chips. now it is being used in a wide variety of processed. It is also used in industrial processes such as in biodiesel production, and as an additive for lubricants

The refined oil is pale yellow or almost colorless and consists of glycerides of Palmitic acid, Oleic acid, Linoleic acid and small amounts of Myristic acid and Fatty acid.

The cotton plant is a small shrub that grows in hot places that need abundant water and fertile land. Cotton is one of the most important crops grown globally, there are thousands of hectares of farms in many countries in Asia and Africa. working on cotton cultivation to meet the requirements of the global market for fabric cotton, China ranks first in the world in cotton production with 7 million tons annually, then India is in second place with 6 million tons annually, and third is the United States of America with 3 and a half million tons annually

The scientific name of cotton is: Gossypium SPP

Name: Cotton

Family: Malvacede

A brief history of Cotton:

The oldest found in history records about cotton is the presence of cotton fabrics in India, where it was found buried underground more than 3 thousand years ago, as well as in Peru, South America.

Scientists found samples of cotton fabrics dating back more than 2500 years.

The most important divisions of cotton:

Many scientists tried to divide the types of cotton, so it has many divisions, the most important ones are:

1- Modern cottons: containing 26 pairs of chromosomes, including:

A- American cotton (Irish) Gossypium Hirstum

B- Sea Island cotton (Peru) Gossypium Barbabense

2- Old cottons: containing 13 pairs of chromosomes, including:

A – Indian cotton (Asian) Gossypium Arboretum

b- African cotton Gossypium Herbaceum

The Cottonseed contains approximately 15-25% of oil and 20-25 % high quality protein, while the pulp contains 30-38% oil.

Crude oil is dark green color and is useless due to the amount of non-oily materials, which are:

  • Colorants
  • Gossypol
  • Phospholipids
  • Carbohydrates
  • Resins
  • Phosphoinositide’s
  • Sterols
  • Related pigments
  • Free fatty acids more than 2%

Cottonseed oil contains more saturated fatty acids (21-25%) than most equivalent oils in iodine number.

Oil partially freezes when stored at a temperature below 10-16°C
