Abstract:
To avoid the loss of carotenoids and increasing the tannin content associated with pasteurization, we tested ultra-high pressure treatment of ripe persimmon beverage. We compared microbial counts (aerobic bacteria, coliforms, and mould), carotenoid contents, and water-soluble tannin contents between heat- and ultra-high pressure-treated beverages. No microbial contamination was detected after pasteurization or ultra-high pressure treatment at 400 MPa for more than 5 min. Ultra-high pressure treatment significantly prevented the reduction in carotenoids (lutein, zeaxanthin, β-cryptoxanthin, β-carotene, lycopene), with losses of 3.9–28.7%, as compared to the 65% loss after pasteurization. Moreover, ultra-high pressure did not induce an increase in water-soluble tannin, which causes astringent taste, whereas water-soluble tannins were increased three times by heat treatment. In conclusion, ultra-high pressure showed the same microbial control effect as pasteurization, while it did not cause carotenoid degeneration and increased tannin and thus, it better maintained the quality of ripe persimmon beverage.
