Standardization of the penaeus monodon, penaeus vannameiand litopenaeus stylirostris capital reach process

Abstract

Currently, there is a high demand for marine products, which has led to the development of these industries at an artisanal and industrial level. One of these developments corresponds to the shrimp farming line since, Colombia has presented a 37% increase in shrimp production. These actions generated by the shrimp farming economy, have caused the ecological imbalance due to the inadequate disposal of solid waste generated in the different stages of processing, which are discharged into the sea without previous treatments. According to the situation presented above, this research consisted in the experimental design of the standardization of the process of obtaining chitosan from the mixtures of shrimp exoskeletons of the varieties penaeus monodon, penaeus vannamei and litopenaeus stylirostris, applying a chemical treatment which involved demineralization processes (1M HCl), deproteinization (3M NaOH) and deacetylation (50% NaOH), obtaining a chitosan yield of 21.64%. Subsequently, a degree of deacetylation of 64.4% for chitosan was determined from potentiometric titration. finally, the economic study of production from raw material was carried out, being $ 12655 for 1 kg of chitosan.
