Information about our CHITIN (made of shrimp head)

Chitin is a linear polymer and the second most abundant natural biopolymer on Earth (after cellulose). It is found in fungi, plankton and the exoskeletons of insects and crustaceans, and organisms generate about 100 billion tonnes of chitin every year. Currently, the polymer and its water soluble derivative, chitosan, are used in only a few niche areas of industrial chemistry, such as cosmetics, textiles, water treatment and biomedicine. Its potential is much greater. Chitin of good quality we provide is mainly produced from shrimps heads, by-products from shrimp farm and processing in the South of Vietnam.

Chitin ist ein lineares Polymer und das zweithäufigste natürliche Biopolymer auf der Erde (nach Cellulose). Es findet sich in Pilzen, Plankton und den Exoskeletten von Insekten und Krebstieren. Die Organismen erzeugen jährlich etwa 100 Milliarden Tonnen Chitin. Derzeit werden das Polymer und sein wasserlösliches Derivat Chitosan in nur wenigen Nischenbereichen der industriellen Chemie wie Kosmetik, Textilien, Wasseraufbereitung und Biomedizin eingesetzt. Sein Potenzial ist viel größer. Chitin von guter Qualität produzieren wir vor allem aus Garnelenköpfen, Nebenprodukte von Garnelenfarmen und deren Verarbeitung im Süden von Vietnam.

Bioactive Compounds from By-Products of Shrimp Processing Industry in Vietnam

shrimp by-products, chitosan, lipid-mineral-rich carotenoprotein

Shrimp heads from the shrimp processing industry in Vietnam can be a good source for the production of bioactive compounds. It is estimated that there is an amount of 200,000 metric tons of shrimp by-products annually from two main species: black tiger shrimp (Penaeus monodon) and white shrimp (Penaeus vannamei). We found that the shrimp by-products can be used as raw materials for extraction of chitosan and lipid-mineral-rich carotenoprotein by combining chemical and biological treatment. Chitosan has been recognized as a multifunctional bioactive compound and has been used widely in food, biotechnology, cosmetics and medicine. Lipid-mineral-rich carotenoprotein can be used as a supplement in food and aqua-feed with good nutrional and functional properties. Besides, the characteristics of these products have been evaluated and reported. These results proved that high quality chitosan and lipid-mineral-rich carotenoprotein can be obtained from shrimp by-products.

Vietnam is a major exporter of shrimp to the world market thanks to a rise in shrimp aquaculture farming in recent years. In 2016, the shrimp production of the country reached 650,000 tons with 700,000 ha and Vietnam exported shrimps with a worth reaching approximately US$ 3.1 billion.

Shrimp is usually processed to obtain shrimp meat for export. The 35 - 45% leftovers are shells and heads considered as by-products. As a result, shrimp processing leads to massive amounts of shrimp biowaste, estimated to be more than 200,000 metric tons (wet weight) per year. The major components of the shrimp by-products are protein, chitin (deacetylated chitosan), lipid, minerals. It contains also a small amount of valuable carotenoids. Chitosan, a valuable bioactive compound, has widely used in food, agriculture, biotechnology, cosmetics, medicine and waste treatment. Other components from shrimp processing waste are minerals, lipid and carotenoprotein that have been widely used as functional ingredients in food and aquafeed.

Materials and methods

 

Shrimp heads as a by-product of white shrimp species was collected from seafood processing factories in Vietnam. After collection, the shrimp waste was transported to the factories. The by-product then was washed and treated.
