Chitin and chitosan as natural flocculants for beer

Chitin (5 mg L −1) and chitosan (5 mg L −1) were also tested separately as flocculants at laboratory scale (jar of 4 L) and industrial scale (tank of 1000 L) of beer samples after sterilization at 121 ± 1 °C for 30 min. Flocculants added to the beer samples were mixed properly and were stored at 17 ± 1 °C for two days and later at 4 ±

The use of chitosan as a flocculant in mammalian cell culture

Chitosan is an ideal flocculant for biotechnology applications as it is produced from non-mammalian sources (typically arthropod shells) and is also available in a highly purified form that is low in heavy metals, volatile organics and microbial materials. Chitosan is a polymer of deacetylated chitin.

Chitin and Chitosan Extracted from Shrimp Waste Using Fish

Extraction and depolymerisation of chitin and chitosan from shrimp waste material was carried out using fish proteases aided process. A high deproteinization level (80 %) was recorded with an Enzyme/Substrate ratio of 10 U/mg. The demineralization of shrimp waste was completely achieved within 6 h at room temperature in HCl 1.25 M, and the residual content of calcium in chitin was below 0.01 %

INTRODUCTION. Chitin is an important structural component of the cell wall of fungi and yeasts and the main carbohydrate component of arthropod exoskeletons. 1 After cellulose, it is the second most abundant biopolymer present in nature. 2 The production of chitin in the biosphere is estimated to be around 1000 billion (10 11) tons per year. 3 Chitin was isolated for the first time in 1799

Chitin is a polymer of β-(1→4) connected to N-acetyl glucosamine subunits as shown in (Fig. 3–1A).It is mainly used as raw material to produce other derivatives like chitosan, chito-oligosaccharides, and glucosamine (Bhaskar et al., 2007), although chitin remains industrially unemployed due to its insolubility in aqueous and organic solvents (Chandumpai et al., 2004).
