Abstract

Functional dairy products represent a substantial area of interest, but the market offers a limited variety of products enriched with oligopeptides. This study focused on the incorporation of high Fischer ratio oligopeptide (HFO) derived from whey protein into goat milk using ultrasonic-assisted pasteurization. A comprehensive examination was conducted to assess the impact of the oligopeptide on the physicochemical properties, stability, and functional characteristics of goat milk. This analysis encompassed the evaluation of protein composition and content, antioxidant capacity, and various other functional attributes. The results revealed that HFO addition significantly increased both protein and whey protein content, enhancing nutritional value. Moreover, HFO fortification notably improved antioxidant activity, foamability, and emulsification properties. Although HFO incorporation elevated viscosity and particle size and reduced the absolute zeta potential, it minimally affected the distribution of fat globules. Storage stability studies indicated that HFO supplementation contributed to extending the shelf life of pasteurized milk. This study demonstrates the dual functionality of HFO in enhancing the nutritional profile and improving the techno-functional properties of goat milk. These findings offer valuable insights for advancing the production of functional goat milk products using oligopeptides as bioactive ingredients or specialized foods for medical purposes.

高费雪比寡肽强化羊奶:提高蛋白质营养价值和改善功能特性的双重功效研究。
功能性乳制品代表了一个重要的领域,但市场上提供的富含寡肽的产品种类有限。本研究的重点是利用超声波辅助巴氏杀菌技术将乳清蛋白中提取的高费雪比寡肽(HFO)掺入羊奶中。研究了该寡肽对羊奶理化性质、稳定性和功能特性的影响。该分析包括蛋白质组成和含量、抗氧化能力和各种其他功能属性的评估。结果表明,添加HFO显著提高了蛋白质和乳清蛋白含量,提高了营养价值。此外,添加HFO显著提高了牛奶的抗氧化活性、起泡性和乳化性能。虽然HFO的掺入提高了粘度和粒径,降低了绝对zeta电位,但它对脂肪球的分布影响很小。储存稳定性研究表明,添加HFO有助于延长巴氏杀菌奶的保质期。本研究证明了HFO在提高羊奶营养成分和改善羊奶技术功能特性方面的双重功能。这些发现为推进使用寡肽作为生物活性成分的功能性羊奶产品的生产或用于医疗目的的专门食品提供了有价值的见解。
