The costs and harsh conditions associated with extraction of chitin and its transformation to chitosan currently limit their production. A re-examination of the processing steps, demineralization and deproteination[, ] can contribute to increased utilization of the waste[. One of the objectives was] to optimize deproteination with [an] alkaline solution[. The deproteination] step was facilitated by increasing the temperature of extraction. Extractability of protein increased... as well as [the] temperature... 4, record 1, English, - deproteinization

La déprotéination de la chitine consiste à solubiliser les protéines présentes dans la matrice de chitine dans une solution aqueuse. Elle peut être effectuée de façon douce ou sévère. Les méthodes douces utilisent des enzymes qui dégradent les protéines en peptides solubles dans l'eau. Ces méthodes sont peu couteuses, mais ne permettent pas l'élimination complète des protéines. L'emploi de soude à température élevée est généralement utilisé pour solubiliser une plus grande partie des protéines. 2, record 1, French, - d%C3%A9prot%C3%A9inisation

In order to improve the removal efficiency of proteins and minerals in chitin from shrimp shells, a successive two-step fermentation was employed... A strain with high protease activity... and a [strain] capable of producing lactic acid... were isolated from a traditional fermented shrimp paste. The [deproteination] and [demineralization] efficiency were significantly improved, which indicates the applicable potential in chitin extraction. 2, record 2, English, - chitin%20extraction

Chitosan, the deacetylated form of chitin, exhibits many biological activities including antifungal, antibacterial properties, elicitation of plant defence reactions, wound-healing properties, tumour inhibition and nutritional effects. Its biological and physico-chemical properties make it an attractive biopolymer for applications in many areas such as food and agriculture, medicine, cosmetics, textiles and water treatment. 3, record 2, English, - chitin%20extraction

La grande disponibilité des carapaces de crevettes et leur teneur élevée en chitine en font la source principale de ce produit. L'extraction de la chitine de la carapace nécessite au moins deux étapes distinctes lorsque l'on procède par méthode chimique : la déminéralisation en milieu acide et la déprotéination en milieu basique. 3, record 2, French, - extraction%20de%20chitine

La chitine est extraite de la carapace des crevettes principalement pour la transformer en chitosane. On retrouve aujourd'hui une multitude d'applications au chitosane dans plusieurs domaines. Il possède des propriétés antibactériennes et antifongiques pouvant être mises à profit tant en agriculture qu'en alimentation [...] Des films à base de chitosane peuvent être appliqués sur des aliments afin de préserver leur intégrité [...] La chitosane sert aussi d'immunostimulateur, d'agent antifongique et de chélateur de métaux [...], de gras et d'autres matières organiques [...] 3, record 2, French, - extraction%20de%20chitine
