“…The main source of milk protein in pudding is milk powder, which contains 9.8 %–28.5 % milk fat, 15 %–24 % protein, and 32 %–67.5 % lactose (Y. H. Li, Wang, Guo, Shao, & Xu, 2019 ). Due to the pudding product’s water content (up to 75 %), pH (approximately 6.5), cold storage conditions (4 ± 2 °C), and room temperature conditions (25 ± 5 °C) ( Moufle, Jamet, & Karoui, 2017 ), the pudding is likely prone to microbial spoilage, protein oxidation, and lipid oxidation in pudding ( Degirmenci & Erkurt, 2020 ). Therefore, it takes precautionary measures to address the deteriorating pudding quality caused by the above reactions.…”
