Dry shrimp heads & shells

Dry shrimp heads & shells

Shrimps consumption has considerably increased worldwide. With higher consumption, there is an increased amount of waste generated. It is a well known fact that meat makes only 50% of the shrimp while the shells, heads and tails make other 50% and are discarded. With an increased consumption and processing of shrimps comes the problem of managing the waste. India alone generates 150,000 tons of shrimp waste per annum.

In the quest to find a solution to the problem of waste management and as the saying goes ‘Necessity is the Mother of all inventions’ managing the huge amount of waste became need of the hour.

Waste management experts and researchers hit upon a possible potentiality of shrimp waste into valuable products, mainly bioactive compounds like chitin, chitosan, glucosamine, astaxanthin, amino acids and fatty acids etc.

These bioactive compounds have a wide range of applications including medical therapies, cosmetics, paper pulp, textile industry, biotechnology and food applications.

Shrimp waste contains protein, chitin and minerals. Removing protein and mineral will give you the Chitin.

Latest discovery of biodegradable plastic by researchers at Harvard University proves that shrimp waste can replace the toxic plastic, which is choking the planet. Biodegradable plastic will be demand of the very near future and has a great potential.

There is a constant research going on world over for more and more potential applications of chitin, chitosan, glucosamine etc

Chitin is a raw material for chitosan and glucosamine hydrochloride. Chitin from shrimp shells can be used to make plastic material. Chitin plastic does not simply replace the carbon source for the polymer but it actually replaces the carbon based plastic polymer by making it totally biodegradable and sustainable material.

Chitin is an organic compound extracted from shrimp shell to develop chitosan, a bioplastic material for plastic packaging and bags.

Chitin is a linear polymer of anhydro N-acetyl-D-glucosamine.

Hydrolysis of Chitin by conc. Hydrochloric acid or HCl produces Glucosamine hydrochloride. Deacetylating it with hot conc. sodium hydrochloride solution or caustic soda it produces Chitosan.

Glucosamine, especially glucosamine sulfate, is extracted from the shells of shellfish to make dietary supplements. A synthetic form is made in laboratories, also.

Glucosamine is normally consumed in different forms, including:

• Glucosamine sulfate
• Glucosamine hydrochloride
• N-acetyl-glucosamine

Uses of Glucosamine:

• Glucosamine plays a vital role in building cartilage, and many people take it as a supplement.
• Glucosamine reduces osteoarthritis-related pain, stiffness, and swelling in the joints.
• It improves function in people with knee or hip osteoarthritis.
• It provides continued relief of symptoms for up to 3 months after someone stops treatment.
