Accurate and automatic real-time recognition of shrimp with without shells is the key to improve efficiency peeling machines reduce labor cost. Existing methods cannot obtain excellent accuracy in absence target samples because there are too many species a complete dataset. In this paper, we propose tactile method universal applicability. First, obtained data, e.g., texture hardness surface shr...

Worldwide every year approximately 140 million tonnes of synthetic polymers are produced. These polymers are stable and their degradation cycle in the biosphere is limited. This necessitates the need for natural biodegradable polymers which fit into the ecological cycle. Among these biopolymers, chitosan, a partially deacetylated form of biopolymer chitin has been receiving more attention due t...

Shrimps have been a popular raw material for the burgeoning marine and food industry contributing to increasing marine waste. Shrimp waste, which is rich in organic compounds is an abundant source of chitin, a natural polymer of N-acetyl-D-glucosamine (GluNac), a reducing sugar. For this respect, chitinase-producing fungi have been extensively studied as biocontrol agents. Locally isolated Tric...

Shrimp waste contains protein that binds to chitin and is difficult digest by poultry, so it necessary carry out a fermentation process using Bacillus licheniformis, Lactobacillus sp., Saccharomyces cerevisiae. This study was conducted determine the Effect of fermented shrimp products resulted in optimal conversion meat protein, carcass weight, abdominal fat native chickens. The method used com...

Urocanic acid is a major ultraviolet (UV)-absorbing chromophore. Chitins are highly crystalline structures that are found predominantly in crustacean shells. Alpha-chitin consists of microfibers that contain nanofibrils embedded in a protein matrix. Acid hydrolysis is a common method used to prepare chitin nanofibrils (NFs). We typically obtain NFs by hydrolyzing chitin with acetic acid. Howeve...

Listeria spp., including the food-borne pathogen Listeria monocytogenes, are ubiquitous microorganisms in the environment and thus are difficult to exclude from food processing plants. The factors that contribute to their multiplication and survival in nature are not well understood, but the ability to catabolize various carbohydrates is likely to be very important. One major source of carbon a...

Chitin is the second most abundant biopolymer in nature after cellulose, and it forms an integral part of insect exoskeletons, crustacean shells, krill and the cell walls of fungal spores, where it is present as a high-molecular-weight molecule. In this study, we showed that a chitin oligosaccharide of lower molecular weight (tetramer) induced genes in Arabidopsis that are principally related t...

Chitin is an abundant polysaccharide found in fungal cell walls, crustacean shells, and insect exoskeletons. The immunological properties of both chitin and its deacetylated derivative chitosan are of relevance because of frequent natural exposure and their use in medical applications. Depending on the preparation studied and the end point measured, these compounds have been reported to induce ...
