Abstract
We investigated the physical characteristics and changes in the functional components of red pepper paste, or gochujang, during fermentation at $20^{\circ}C$ for 90 days with different amounts of sweet persimmon powder. The viscosity of the paste decreased a little with increasing fermentation time. There was no significant difference (p<0.05) in all the treatments during fermentation. The L value, a value, and b value showed a tendency to gradually decrease with increasing fermentation time. And the samples with sweet persimmon powder showed a lower values compared to the control during fermentation. The phenolic compound content of the paste with sweet persimmon powder ranged from 13.72 mg% to 16.13 mg% at an early stage of fermentation, showing a significantly higher value (p<0.05) when increasing the amount of the powder. The content was in the range of 13.72~16.09 mg% on the 90th day in the final stage of fermentation, showing no significant difference (p<0.05) compared to those content at an initial stage of fermentation. The carotenoid content showed significantly higher values (p<0.05) when increasing the amount of sweet persimmon powder. In conclusion, sweet persimmon powder in the red pepper paste would gives a more functional effect which could be from bioactive components, such as phenolic compounds and carotenoids. But, it did not positively affect the color of the red pepper paste.
