“…The experimental mean composition of shrimp waste and the calculated feed for simulation of the plant process are given in Table 1. The protein, mineral, chitin and pigment contents depend markedly on nutritional conditions; the results obtained in this study are in the range reported for this shrimp species ( 33 ). The astaxanthin content was slightly higher, possibly due to the supplementation of shrimp feed with carotenoids ( 34 ).…”

“…The strain L. plantarum has been widely explored for fermentation of chitinous waste, allowing to reach demineralization and deproteinization values higher than 80% ( 8 , 33 , 35 , 36 ). Additionally, the use of co-cultures of microorganisms has been reported as a feasible alternative to obtain demineralization and deproteinization values higher than 90% in less time, increasing the efficiency of the process.…”

“…Additionally, the use of co-cultures of microorganisms has been reported as a feasible alternative to obtain demineralization and deproteinization values higher than 90% in less time, increasing the efficiency of the process. The reported fermentation times are in the range between 3 and 10 days when only one strain is used ( 4 , 8 , 33 , 35 , 37 , 38 ) and between 2 and 4 days when extraction with co-cultures is applied ( 18 , 20 , 36 ). In that case, the use of a mixed culture of L. plantarum, L. bulgaricus and S. thermophilus was an efficient alternative for biotreatment of shrimp waste, since the extraction values attained in the bioreactor experiments were higher than 90% and they were achieved in 50 h. The observed rates of deproteinization and demineralization followed second order kinetics with respect to lactic acid molar concentration (Fig.…”

Chitin is an aminopolysaccharide of industrial interest commonly obtained from shrimp processing waste through chemical or biotechnological means. Current environmental concerns offer a stimulating perspective for chitin bioextraction with lactic acid bacteria since a considerable reduction in the use of corrosive and pollutant products is possible. Nevertheless, the efficiency of this bioprocess is still a matter of discussion. In this work, the experimental studies of chitin bioextraction from Pacific white shrimp (Litopenaeus vannamei) waste with a mixed culture of Lactobacillus plantarum, Lactobacillus bulgaricus and Streptococcus thermophilus are used in process simulation using Aspen Plus software for the analysis of the potential application of a bioprocess on plant scale. The experimental results of characterization in shake flasks and 1-litre bioreactor indicated that 50 h of fermentation with the mixed culture of lactic acid bacteria was enough to extract more than 90 % of minerals and proteins from the shrimp waste. The use of experimental parameters in the simulation allowed a reliable representation of the bioprocess yielding normalized root mean square values below 10 %. Simulation was used for the assessment of the impact of the raw material variability on the production costs and gross margin. In this regard, the gross margin of the operation ranged from 42 to 52 % depending on the raw material composition and product yield

Reviews on biotechnological chitin recovery from crustacean waste and other sources acknowledge. Most of the reviews conclude that although important results on chitin recovery have been achieved, there is still a need for better approaches to improve operational conditions of deproteinization and demineralization processes, such as time, carbon source, pH (initial and during fermentation), volume of inoculum, temperature, among others, in order to apply at industrial level, a bioprocess commercially and environmentally cost/effective viable. The present review aims to gather the most updated available information about research on biotechnological methods to recover chitin from crustacean waste, studied during the past 10 years, focussing on conditions applied to deproteinization (DP) and demineralization (DM), particularly on bioprocessing times and microbial species.

Chitosan is a polycationic polysaccharide with good health and nutritional benefits. This study investigated the effect of chitosan properties, such as, biopolymer structure, viscometric molar mass (Mv), and degree of deacetylation (DD), on the fat‐binding capacity between five chitosan preparations (different origins and characteristics) and three types of fat (soybean oil, margarine, and pork lard). The in vitro fat‐binding tests were performed with soybean oil under different pH to simulate the digestion process in the gastrointestinal tract, followed by tests at constant pH (duodenal pH = 6.8) with three types of fat. Shrimp shell nanochitosan had an average hydrodynamic diameter of 62 nm, while that of shrimp shell chitosan and commercial chitosans (CC1, CC2, and CC3) ranged between 1090 and 1405 nm (determined by DLS). The Mv of chitosan varied between 18 and 260 kDa, and the DD ranged from 62% to 92%. Chitosan with medium Mv and high DD presented better results of fat‐binding capacity in the duodenal pH with soybean oil. This study provides insights into the mechanisms of fat‐binding capacity and its correlation with physicochemical properties of chitosan, pH, and type of fat, allowing the production of chitosan‐based products with improved fat‐binding capacity for several applications.
