What is it about?
Cottonseed meal protein is a useful by-product of cottonseed oil processing industry having a significant potential to overcome daily protein needs of ruminants and non-ruminant animals and aquaculture. But this ability of cottonseed protein is greatly hampered by the presence of gossypol, which is a polyphenolic terpenoid aldehyde and a toxin in cotton plant and cottonseed.

Why is it important?
The large amounts of cottonseed protein available to the tune of 10–11 million metric tons from this cottonseed can satisfy the daily protein needs (50 g per person) of around 600 million people per annum, provided gossypol is eliminated from the meal.
Perspectives
Now a day a great emphasis is on the use of green and food grade solvents which are non-toxic in food applications. We have utilized a green solvent 2-propanol-water for the extraction of gossypol from defatted cottonseed. Every researcher or scientist now needs to utilize green components and sustainable technologies for his/her work as we have reported here.
