摘要

蛋白胨是一种富含氨基酸的水解产物,在高温下不凝固。由于宗教方面的考虑,从陆地动物中生产的商业蛋白胨不能被宣布为合法的。鲶鱼(Clarias gariepinus)和鲶鱼(Pangasius Pangasius)是印度尼西亚鱼类加工业的重要物种。加工过程产生了有价值的副产品。副产品鱼头可作为生产蛋白胨等高经济价值产品的主要原料。研究了不同酸性条件下鲶鱼和鲶鱼头部提取的蛋白胨。观察了其化学组成、产率、颜色参数、溶解度、氨基酸含量、细菌生长速率和生物量等特性。不同酸化条件下获得的鲶鱼蛋白胨(CFP)和鲶鱼蛋白胨(PCP)蛋白质含量均在84.35% ~ 90.80%之间(P<0.05)。CFP和PCP的产率差异显著(P<0.05),介于4.75%和5.66%之间。处理后的蛋白胨溶解度在98.03% ~ 99.52%之间,富含甘氨酸、谷氨酸、脯氨酸和亮氨酸。细菌生长试验表明,CFP和PCP与本研究中测试的商业蛋白胨相比,具有更好的生长速率。此外,鲶鱼和鲶鱼蛋白胨的生物质产量均高于商品产品(P<0.05)。本研究表明,鲶鱼和鲶鱼头可作为蛋白胨生产的替代来源。

Characteristics and Use of Peptones from Catfish (Clarias gariepinus) and Pangas Catfish (Pangasius pangasius) Heads as Bacterial Growth Media
Peptone is a hydrolysate product rich in amino acids, and it is uncoagulated at high temperature. Commercial peptone produced from land animals cannot be declared as acceptable in terms of lawfulness due to religious concerns. Catfish (Clarias gariepinus) and pangas catfish (Pangasius pangasius) are important species for the fish processing industry in Indonesia. The filleting process resulted in value by-products. The fish head as the by-products can be utilized as a main raw material for higher economic value products, such as peptone. The aim of this study was to characterize peptones extracted from the heads of catfish and pangas catfish with different acid conditions. The characteristics of chemical composition, yield, color parameter, solubility, amino acid content, bacterial growth rate and biomass production were observed. The catfish peptone (CFP) and pangas catfish peptone (PCP) obtained with different acid conditions showed high protein content in the range of 84.35% to 90.80% (P<0.05). The yields of CFP and PCP were significantly different (P<0.05) and varied between 4.75% and 5.66%. The solubility of treated peptones varied between 98.03% and 99.52%, and the peptones were rich in glycine, glutamic acid, proline and leucine. Bacterial growth test showed that both CFP and PCP had better growth rates compared to the commercial peptone tested in this study. In addition, the biomass production with peptone from catfish and pangas catfish was higher than that with the commercial product (P<0.05). This research proposed that catfish and pangas catfish heads could be developed as an alternative source for peptone production.
