Abstract

Optimization of antioxidants and angiotensin-converting enzyme (ACE) inhibitory potential gelatin hydrolysate production from Labeo rohita (rohu) swim bladder (SBGH) by alcalase using central composite design (CCD) of response surface methodology (RSM) was investigated. The maximum degree of hydrolysis (DH), 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS), total antioxidants (TAO), and ACE inhibitory activity were achieved at 0.1:1.0 (w/w) enzyme to substrate ratio, 61 °C hydrolysis temperature, and 94-min hydrolysis time. The resulting SBGH obtained at 19.92% DH exhibited the DPPH (24.28 µM TE/mg protein), ABTS (34.47 µM TE/mg protein), TAO (12.01 µg AAE/mg protein), and ACE inhibitory (4.91 µg/mg protein) activity. Furthermore, SBGH at 100 µg/ml displayed osteogenic property without any toxic effects on MC3T3-E1 cells. Besides, the protein content of rohu swim bladder gelatin (SBG) and SBGH was 93.68% and 94.98%, respectively. Both SBG and SBGH were rich in glycine, proline, glutamic acid, alanine, arginine, and hydroxyproline amino acids. Therefore, SBGH could be an effective nutraceutical in functional food development.

从 Labeo rohita 鱼鳔中生产抗氧化剂、血管紧张素转换酶抑制物和成骨明胶水解物

摘要

采用响应面法 (RSM) 的中心组合设计 (CCD),研究了通过 Alcalase对Labeo rohita (rohu) 鱼鳔 (SBGH)生产明胶水解产物的抗氧化剂和血管紧张素转换酶 (ACE) 抑制潜力的优化。最大水解度(DH)、2,2-二苯基-1-三硝基苯肼(DPPH)、2,2'-连氮基-双-3-乙基苯并噻唑啉-6-磺酸(ABTS)、总抗氧化剂(TAO)和在酶与底物比例为 0.1:1.0 (w/w)、水解温度为 61 °C、水解时间为 94 分钟时,可实现 ACE 抑制活性。在 19.92% DH 下获得的 SBGH 显示出 DPPH(24.28 µM TE/mg 蛋白质)、ABTS(34.47 µM TE/mg 蛋白质)、TAO(12.01 µg AAE/mg 蛋白质)和 ACE 抑制(4.91 µg/mg 蛋白质)活动。此外,100 µg/ml 的 SBGH 显示出成骨特性,对 MC3T3-E1 细胞没有任何毒性作用。此外,南亚野鲮鱼鳔明胶(SBG)和SBGH的蛋白质含量分别为93.68%和94.98%。 SBG和SBGH均富含甘氨酸、脯氨酸、谷氨酸、丙氨酸、精氨酸和羟脯氨酸氨基酸。因此,SBGH 可能成为功能性食品开发中的有效营养保健品。
