Chitin is the second most abundant polysaccharide,produced mainly as an industrial waste stream during crustacean *** can be derived into chitosan through the deacetylation *** of shrimp waste into chitosan via the deacetylation process could be considered a practical approach for shell waste *** this study,chitosan’s physicochemical characteristics extracted from two types of Pacific white leg shrimp,***’s shell(i.e.,rough and smooth),were compared with commercial *** yield,moisture,ash,solubility,water and fat binding capacity were *** degree of deacetylation(DDA)was calculated using FTIR,and their chemical Structure was confirmed using XRD and *** extracted chitosan showed no significant difference in yield,moisture,ash,solubility and water binding capacity but showed a significant difference with commercial ***,the fat binding capacity of commercial chitosan showed the lowest percentage(408.34±0.83%)as compared to extracted chitosan(smooth shell 549.59±12.48%;rough shell 500.55±12.10%).The DDA indicated that extracted chitosan from the smooth and rough shell was considered good chitosan as compared to commercial chitosan with 84.08±1.27%,80.78±0.79%and 74.99±1.48%,***,the presence of hydroxyl and amino groups from FTIR and a good crystallinity index was recorded using XRD of extracted *** on observed characteristics,shrimp shell waste from *** can achieve chitosan standard quality as a biopolymer and highly potential to be applied in various industrial applications.
