Camel whey protein hydrolysates were generated using gastric (pepsin) and pancreatic (trypsin and chymotrypsin) enzymes for 3 and 6 h of hydrolysis time. Hydrolysates were characterized using degree of hydrolysis (DH) and reverse phase-high performance liquid chromatography (RP-HPLC). Camel whey protein hydrolysates (CWPHs) showed DH ranging from 11 to 47.5%, with chymotrypsin (6 h) and trypsin (3 h) generated hydrolysates exhibiting highest and lowest DH, respectively. HPLC analysis revealed that α-lactalbumin underwent complete degradation and newer shorter peptides were generated. Inhibition of cholesteryl esterase, (CE) pancreatic lipase and anti-hypertensive properties via angiotensin converting enzyme (ACE) inhibition were found to be higher in pepsin (6 h) and (3 h) generated CWPHs, respectively. Pepsin (P3 and P6) and trypsin (T6) generated hydrolysates exhibited highest anti-haemolytic activity followed by chymotrypsin generated CWPHs. Whereas, trypsin (T3) generated hydrolysate showed minimum anti-haemolytic activity (8.02% ± 1.40). Overall, CWPHs displayed enhanced inhibition of CE, lipase, ACE and anti-hemolytic properties upon hydrolysis, providing a strong scientific base for their potential to be considered as functional and nutraceutical ingredients. This study provides a strong indication of biologically active peptides responsible for health related bioactive properties reported herein. Future work must include identification of the peptides in the most potent camel whey protein hydrolysates.

骆驼乳清蛋白水解物显示出增强的胆固醇酯酶和脂肪酶抑制,抗高血压和抗溶血特性

使用胃(胃蛋白酶)和胰腺(胰蛋白酶和胰凝乳蛋白酶)酶产生骆驼乳清蛋白水解物,水解时间分别为3和6小时。使用水解度(DH)和反相高效液相色谱(RP-HPLC)对水解产物进行表征。骆驼乳清蛋白水解物(CWPHs)的DH范围为11%至47.5%,其中胰凝乳蛋白酶(6 h)和胰蛋白酶(3 h)生成的水解物分别显示最高和最低的DH。HPLC分析表明,α-乳白蛋白已完全降解,并生成了更新的较短肽。发现在胃蛋白酶(6 h)和(3 h)产生的CWPHs中,胆甾醇酯酶,(CE)胰脂肪酶的抑制作用和通过血管紧张素转化酶(ACE)抑制的抗高血压特性分别更高。胃蛋白酶(P3和P6)和胰蛋白酶(T6)生成的水解产物表现出最高的抗溶血活性,其次是胰凝乳蛋白酶生成的CWPH。而胰蛋白酶(T3)产生的水解产物显示出最小的抗溶血活性(8.02%±1.40)。总体而言,CWPH在水解时表现出对CE,脂肪酶,ACE和抗溶血特性的增强抑制作用,为其潜在的功能和营养成分提供了强大的科学基础。该研究为本文报道的与健康相关的生物活性特性负责的生物活性肽提供了强有力的指示。未来的工作必须包括最有效的骆驼乳清蛋白水解物中肽的鉴定。胰蛋白酶(T3)产生的水解产物显示出最小的抗溶血活性(8.02%±1.40)。总体而言,CWPH在水解时表现出对CE,脂肪酶,ACE和抗溶血特性的增强抑制作用,为其潜在的功能和营养成分提供了强大的科学基础。该研究为本文报道的与健康相关的生物活性特性负责的生物活性肽提供了强有力的指示。未来的工作必须包括最有效的骆驼乳清蛋白水解物中肽的鉴定。胰蛋白酶(T3)产生的水解产物显示出最小的抗溶血活性(8.02%±1.40)。总体而言,CWPH在水解时表现出对CE,脂肪酶,ACE和抗溶血特性的增强抑制作用,为其潜在的功能和营养成分提供了强大的科学基础。该研究为本文报道的与健康相关的生物活性特性负责的生物活性肽提供了强有力的指示。未来的工作必须包括最有效的骆驼乳清蛋白水解物中肽的鉴定。该研究为本文报道的与健康相关的生物活性特性负责的生物活性肽提供了强有力的指示。未来的工作必须包括最有效的骆驼乳清蛋白水解物中肽的鉴定。该研究为本文报道的与健康相关的生物活性特性负责的生物活性肽提供了强有力的指示。未来的工作必须包括最有效的骆驼乳清蛋白水解物中肽的鉴定。
