Abstract
In the present study, chitin was extracted from shrimp (Metapenaeopsis Stridulans) wastes chemically, biologically (via single-step (L or B), co-fermentation (L/B or B/L) using Bacillus subtilis, and Lactobacillus Plantarum Evaluation of chitosan samples quality by using proximate analysis, physicochemical characteristics. Although the bio-extracted chitosan samples yields were less than the chemically extracted. The intrinsic viscosity and molecular weights of the bio-extracted chitosan samples were lower than the chemically extracted samples. A current study applying it to fish fillets reduces the total bacterial count by about one log when compared to control samples. The Chitosan sample (B/L) was the most effective among other chitosan solutions (3.30±0.55), after 10 d refrigerated storage, all findings of total bacterial reduction of chitosan solutions up to 10 days, were below the limits of the Egyptian Organization for Standardization and Quality Control. the most sensory evaluation followed by (Ch and L).
