Comparison of the quality attributes of coconut waters by high‐pressure processing and high‐temperature short time during the refrigerated storage

摘要

This study compared the shelf life and quality of high‐pressure processing (HPP) and high‐temperature short time (HTST)‐treated coconut water at 4°C. HPP of 500?MPa (5?min) and HTST of 72°C (15?s) treatments could ensure microbial safety of coconut water during refrigerated storage of 25 and 15?days, respectively. At the end of 15?days of storage, loss of 51.54% amino acids and 32.37% protein, and retention of 65.0% total sugars, 64.51% ascorbic acid, and 74.34% total phenols were found in HTST group. More nutrient contents, 76.85% amino acids, 76.76% total protein, and 93.17% total phenols, were retained in HPP groups at the end of 25?days of storage. HPP‐treated fresh‐like product could provide an effective approach of extending shelf life of coconut water.
