다진 마늘의 제조 중 발생하는 효소적 갈변을 막기 위해 산업적으로 적용되는 방법은 주로 화학적인 갈변저해제를 이용하는 경우가 다수이나, 최근 소비자의 천연물에 대한 수요 증대를 감안하여 천연물 유래의 갈변저해제를 탐색할 필요가 있다. 따라서 본 연구에서는 천연물 유래의 갈변저해제 중 효과적으로 나타난 감초 추출물의 갈변저해 효과를 조사하였다. 또 기존 다진 마늘의 갈변저해에 효과적인 것으로 알려져 있는 구연산과의 병용 효과를 동시에 조사하여 효율

Chemical methods using browning inhibitors have been used to control the browning of chopped garlic. However, consumer demand for natural products is increasing, and we therefore investigated the antibrowning effect of natural licorice root extract on chopped garlic. We used a combination of licorice extract and citric acid. Chopped garlic was exposed to citric acid and licorice extract at various levels and L values were measured during storage at . Licorice extract was effective as an initial antibrowning, and a mixture of licorice extract and citric acid was effective in inhibition of browning during storage. The effective mixing ratio of licorice extract and citric acid was 5:5 and 2:8. This indicates that licorice extract and citric acid synergistically act to inhibit browning of chopped garlic. Licorice extracts with higher levels of glycyrrhizin were more effective as antibrowning agents for chopped garlic.
