Pacific white shrimp (Litopenaeus vannamei) accounts for 90% of the global aquaculture shrimp production. Thailand has been the world's leading exporter of cultivated shrimp since the mid-90s. Pacific white shrimp and its products have become economically important for Thailand. By the year 2010, frozen Pacific white shrimp and products were manufactured and exported totally for 407,978 metric tons, particularly to USA and Japan . During shrimp processing, a large amount of by-products including cephalothorax, shell, etc. is generated. To exploit those left-over, cephalothoraxes have been used as raw material for production of shrimp hydrolysate, shrimp flavorant, carotenoid and chitin/chitosan. Shrimp shell has been intensively used for carotenoprotein extraction
