Storage stability of pennywort juice as affected by high pressure and thermal processing
The physicochemical and microbiological qualities of pressurized (500 MPa/30°C/20 min) and pasteurized (90°C/3 min) pennywort juices were determined during chilled storage (4°C) for 4 months. The color parameters and pH values in both processed juices exhibited no changes upon storage. Moreover, it...

The physicochemical and microbiological qualities of pressurized (500 MPa/30°C/20 min) and pasteurized (90°C/3 min) pennywort juices were determined during chilled storage (4°C) for 4 months.

Moreover, it was found that high pressure could preserve various bioactive components including ascorbic acid, total phenolic compounds and antioxidant capacity (FRAP assay), superior than pasteurization.
