단감의 수확 및 저장 중에 발생한 불량과실을 이용할 목적으로 분말화하기 위한 기초연구로서 본 실험을 행하였다. 일반성분 조성은 조단백질, 조지방, 조회분의 순으로 열풍건조 처리구는 0.9-1.1%, 15.0-39.0%, 2.3-3.3%이었으며, 동결건조 처리구는 1.3-2.2%, 27.0-49.0%, 2.5%로 나타났다. 무기성분 조성은 열풍과 동결건조 처리구 모두 potassium, magnesium, phosphorus; calcium, so
To utilize deteriorated sweet persimmon(Diospyros kaki T.) effectively, this study was investigated about the effective (Dying method of the powder. Chemical components, minerals, fatty acids and amino acids of hot-air dried and freeze dried conditions were determined Sample conditions used on analysis as follow; pretreatments of hot-air dry and freeze dry were soft, soft+peel, mixer, mixer+peel. The contents of crude protein, crude lipid, crude ash of hot-air dry were 0.9-1.1%,15.0-39.0% and 2.3-3.3%, respectively. And those of freeze dry were 1.3-2.2%, 27.-49.0% and 2.5%, respectively. Potassium, magnesium, phosphorus, calcium and sodium content in hot-air dry and freeze dry were high. Other minerals were less than 3.00ppm in all conditions. The major fatty acid contents were detected capric acid(C10:0/), lauric acid(Cl2:0)/, tridecanoic acid(C13:00/), palmitic acid(Cl6:00/), palmitoleic acid(Cl6:1/), oleic acid(C18:1), linoleic acid(C18:2/), linolenic acid(C18:3/). The essential amino acids such as aspartic acid, threonine, serine, glutamic acid, glycine, alanine, valine, methirmine, isoleucine, leucine, tryosine, phenylalanine, histidine, lysine, arginine in freeze dry were contained richly. On the basis of chemical analysis, hot-air dry method will have to supply the additional different method, because simple hot-air dry method was shorten the dry time but had many problems. Therefore, the effective drying method considering changed color and nutrition was shown freeze dry method.
