This study was carried out to investigate the physicochemical characteristics of maturating and dried jujube. The moisture contents of the unripe and ripe jujube were found to be 84.66 and 66.45%, respectively, but that of the dried jujube was 31.48%. The crude-fat and crude-ash contents of the drie...

대추가 저장성이 좋지 못한 이유는 무엇인가? | 그러나 대추는 당도가 높아 수확기간이 10일 정도로 짧아 저장성이 좋지 못하기 때문에 수확시기에 생과 형태로 일부 소비되고, 대부분은 건과 형태로 소비가 이루어지고 있는 실정이다(6). 대추가 저장성이 좋지 못한 이유는 저장기간 동안 과육이 polygalacturonase와 같은 연화효소에 의해 세포벽의 pectin질이 연화되기 때문인 것으로 알려져 있다(7). 과실의 연화는 생체내에 존재하는 세포벽 분해효소의 작용에 의하여 세포벽성분이 분해되어 물성변화를 초래함으로써 일어난다. | |
미숙 및 완숙 대추와 건조 대추의 수분함량은? | 본 연구는 대추의 성숙과 건조에 따른 이화학적 특성을 비교 분석하고자 미숙 및 완숙 대추와 건조 대추의 이화학적 특성을 조사하여 비교 분석하였다. 대추 열매의 수분함량은 미숙 대추 84.66%, 완숙 대추 66.45%이었고 건조대추의 수분함량은 31.48%이었다. 조지방의 함량은 미숙 대추와 완숙 대추에서는 차이가 없었으나, 건조 대추에서 0. | |
대추는 어떤 질환에 효능이 있는가? | inermis Rehder)는 갈매나무과에 속하는 낙엽활엽교목의 열매로서 중국계는 Zizyphus jujuba Miller라 하고 인도계는 Zizyphus mauritiana LAM이라 하며, 유럽 남부, 아시아 남부 및 동부가 원산지로 우리나라, 중국, 일본에 분포하고 있고, 우리나라에서는 재래종인 복조, 보은, 산조대추 등이 분포하고 있으며, 개발종인 월출, 무등, 금성대추 등은 극히 일부 지역에서만 재배되고 있다 (1). 한편 대추는 고려시대부터 식용으로 이용되었다는 기록이 있으며, 불면증이나 이뇨작용, 강장작용, 기침, 빈혈, 정신 안정 등에 효능이 있는 것으로 알려져 약용으로도 이용되어 인스턴트식품 섭취가 많은 현대인의 건강에 도움이 되는 식품 중의 하나로 여겨지고 있다(2). |
