This study aimed to use the potential chitosan processing waste from shrimp heads as a premix to improve the production performance of laying chickens.
This research uses shrimp head waste, NaOH, hydrochloric acid, NaSeO and NaCl solutions. Processing shrimp head waste into chitosan is done in three ways, namely demineralization, deproteination, and deacetylation. Each of the resulting liquid wastes is then mixed until a neutral mixture is obtained. The data observed were the nutrient and amino acid content of liquid waste from the deproteinization, demineralization, and deacetylation processes, as well as the neutral mixture.
The results showed liquid waste from the process of making chitosan from shrimp head waste using deproteination, demineralization, and deacetylation methods, as well as a neutral mixture containing little energy, protein, and fat but is rich in minerals. The most abundant and complete amino acid content is found in deproteination process wastewater and neutral mixtures.
In conclusion, the waste from making chitosan from shrimp head waste through deproteinization, demineralization, and deacetylation, and the neutral mixture contains enough minerals and amino acids needed by livestock, so it has the potential to be used as a premix.
本研究旨在利用虾头中潜在的壳聚糖加工废料作为预混料，以提高蛋鸡的生产性能。
本研究使用虾头废料、氢氧化钠、盐酸、亚硒酸钠和氯化钠溶液。将虾头废料加工成壳聚糖有三种方法，即脱矿质、脱蛋白和脱乙酰化。然后将每种产生的废液混合，直至获得中性混合物。观察的数据包括脱蛋白、脱矿质和脱乙酰化过程以及中性混合物中废液的营养成分和氨基酸含量。
结果表明，使用脱蛋白、脱矿质和脱乙酰化方法从虾头废料制备壳聚糖过程中产生的废液，以及能量、蛋白质和脂肪含量较低但富含矿物质的中性混合物。脱蛋白过程废水和中性混合物中氨基酸含量最丰富且完整。
总之，通过脱蛋白、脱矿质和脱乙酰化从虾头废料制备壳聚糖产生的废料以及中性混合物含有家畜所需的足够矿物质和氨基酸，因此有潜力用作预混料。
