진품콩에 작두콩의 종실을 첨가하여 맛과 영양이 우수한 요구르트를 제조하기 위하여 진품콩에 작두콩의 혼합 비율별로 두유를 착즙하고 유산발효 시킨 제품의 가공특성을 검토하였다. 원료콩의 단백질 함량은 진품콩이 38.0%로 작두콩 27.5f%보다 높았다. 유산발효 중 PH와 당도는 발효개시 후 4시간까지는 급격히 저하했다가 8시간 이후에는 완만하게 감소하였으며 유기산 함량과 유산균 수는 증가하였고, 20시간 발효시 진품콩 100%에 비하여 진품콩 95
This study was conducted to investigate the characteristics of yogurt prepared with different mixing ratios of 'Jinpum ' bean and sword bean(Canavalin gladiata). The crude protein content of 'Jinpum' bean used raw material was 38.0%, whereas that of sword bean was 27.5%. The pH and sugar content of ferment solution were deceased significantly up to 4 hours after strain inoculation but reduced slowly artier 8 hours. The content of organic acid and lactic ferments were increased. After 20 hours fermentation there was no significant differences between yogurt processed with 100% 'Jinpum' bean and yogurt processed with 95% 'Jinpum' bean and 5% sword bean. The number of lactic acid bacteria in yogurt processed with 95% 'Jinpum' bean and 5% sword bean was increased up to 20 hours but thereafter was decreased rapidly, showing the similar values compared to that of yogurt processed with 100% 'Jinpum' bean. The color values of yogurt processed with 95% 'Jinpum' bean and 5% sword bean artier 20 hours fermentation were similar to that of yogurt processed with 100% 'Jinpum' bean whereas those of yogurt processed with 90% 'Jinpum' bean and 10% sword bean were no little difference before and after fermentation. In the result of sensory test of yogurt prepared with 95% 'Jinpum' bean and 5% sword bean, adding strawberry syrup was more preferred than apple syrup.
