Abstract
In this paper, the enzymatic preparation of functional peptides in food and their biological activities were studied in order to develop efficient and sustainable functional food ingredients. With the popularity of the concept of healthy diet, functional peptides have shown great potential in the fields of food, medicine and health products because of their antioxidant, immune regulation, blood pressure reduction and other biological activities. In this paper, the classification, origin and application of functional peptides in the food industry were reviewed, and the importance of functional peptides in improving the nutritional value and health function of food was clarified. In terms of preparation methods, this paper focused on enzymatic preparation technology, through detailed analysis of enzyme characteristics and substrate matching, optimization of enzymatic hydrolysis temperature, time, pH value and substrate concentration and other process parameters, combined with reasonable addition of cofactors, to achieve efficient preparation of functional peptides. At the same time, the trend of automation and intelligence in production process is discussed, and the key role of data-driven in optimizing production process and improving product quality is emphasized. In addition, many factors affecting the biological activity of functional peptides were discussed, including their molecular structure and sequence, molecular weight, preparation conditions and storage stability, etc., which provided a scientific basis for the activity maintenance and application effect of functional peptides. In summary, this study not only enriched the theoretical basis of functional peptide enzymatic preparation, but also provided an important reference for the efficient utilization of functional peptides in the food industry and the development of new products. In the future, with the continuous progress of technology and in-depth research, functional peptides are expected to play an important role in more fields and contribute more to the cause of human health.
