Enzyme assisted extraction of chitin from shrimp shells (Litopenaeus vannamei)
8 BACKGROUND: Chemical chitin extraction generates large amounts of wastes and increases partial 9 deacetylation of the product. Therefore, the use of biological methods for chitin extraction is an 10 interesting alternative. The effects of process conditions on enzyme assisted extraction of chitin from 11 the shrimp shells in a systematic way were the focal points of this study. 12 RESULTS: De...
متن کاملA new method for fast chitin extraction from shells of crab, crayfish and shrimp.
A new method for quick chitin isolation from the shells of crab, crayfish and shrimp is described. The main difference between the new method and the conventional method is two sodium hypochlorite (NaClO) treatments for 10 min each before the processes of demineralisation and deproteinisation. After the NaClO treatment, only 15 min is adequate for the demineralisation and 20 min for the deprote...
متن کاملadsorption of zn (ii) from aqueous solution by using chitin extracted from shrimp shells
background chitin and its derivatives (chitosan) are natural biopolymer produced from crustacean shell, which due to their active functional groups such as amine and hydroxyl have high ability to absorb heavy metals from water and wastewater. the aim of this study was to investigate zinc removal from aqueous solutions by using chitin extracted from shrimp shells. material and methods to study t...
متن کاملEffect of Chitin Extraction Processes on Residual Antimicrobials in Shrimp Shells
The present study examined the influences of industrial chitin extraction processes on the residual oxytetracycline (OTC) and oxolinic acid (OA) in shrimp carapaces and shells. The drugs were orally administered by catheter to the kuruma shrimp (Penaeus japonicus) and vannamei shrimp (Penaeus vannamei). The shrimps were sampled at 6-h post-dosing and their carapaces and shells were collected an...
متن کاملKinetics of N-Deacetylation of Chitin Extracted from Shrimp Shells Collected from Coastal Area of Morocco
Chitosan was obtained from the alkaline N-deacetylation of -chitin, derived from shrimp shells (SS) collected from the Moroccan coast. Effects of temperature, NaOH concentration and reaction time on the kinetics of deacetylation were studied. The degree of deacetylation (DD = 75%) was obtained at T = 120 °C and CNaOH = 12N in a single step for 6h. It was found, from FTIR studies, that the remo...
