摘要: The effects of high pressure homogenization (HPH) on microbial inactivation and quality attributes (physiochemical properties, bioactive components and antioxidant capacity) of mango juice, as well as their changes during storage at 4 degrees C and room temperature were investigated. Pressure levels ranged from 40 to 190 MPa, the inlet temperature from 20 degrees C to 60 degrees C and the number of passes from 1 to 5. Complete inactivation of molds and yeasts was achieved by 1 and 3 passes at 190 MPa and 60 degrees C, while total plate count was below 2.0 log(10) CFU/mL. No multiplication of microorganisms was observed in mango juice over 60 days of storage at 4 degrees C. HPH treatment could retain or even increase the carotenoids and total phenols by 11.8% and 21.4%, respectively, while significant reductions were found for heat treatment (HT) samples. During the storage of 60 days, HPH treatment also provided better preservation of color, bioactive components and antioxidant capacity of mango juice than HT.
