Influence of Pasteurization and Storage on Dynamic In Vitro Gastric Digestion of Milk Proteins: Quantitative Insights Based on Peptidomics

Abstract: It is important to evaluate the nutritional quality of milk during the shelf-life, especially during home storage, from a consumer viewpoint. In this study, we investigated the impact of pasteurization (85 °C/15 s) and subsequent storage (at 4 °C for 7 days) on the coagulation behavior of milk and protein digestibility in a dynamic in vitro gastric digestion test. A high level of hydration in curd formed in pasteurized milk upon 7-day cold storage compared to raw and pasteurized milk, indicating fast pepsin di… Show more

“…Research conducted by Li et al 46 and Prayitno et al 47 has shed light on the dynamic changes in milk protein content during prolonged refrigerated storage. The findings indicate a rapid hydrolysis of milk proteins, resulting in an increased intensity of peptides as the storage time extends.…”

“…Peptidomic or proteomic approaches are involved in diverse areas of food analyses, concerning issues such as the authenticity and origin of food products, changes taking place during food processing or storage [189][190][191], analysis of food protein hydrolysates [192], the biological activity of peptides contained in foods (milk, eggs) or raw materials [193][194][195][196] or factors influencing proteolysis of human milk proteins [197].…”

“…Estos porcentajes de proteólisis coinciden con valores publicados previamente para fórmulas infantiles. Li et al (2020) sometieron a leche fluida pasteurizada a un proceso de digestión gástrica dinámica in vitro y obtuvieron grados de proteólisis de ~15-30 % por OPA, luego de 60 min de digestión gástrica. Halabi et al (2020) investigaron la digestibilidad in vitro estática de fórmulas infantiles con distinto perfil de WP sometidas a distintos tratamientos térmicos y obtuvieron valores de hidrólisis proteica cuantificadas por el método de OPA entre 30 y 60 % al cabo de 60 min de digestión intestinal.…”
