Blacken spoilage is one of the common problems during the cold storage of dried persimmon in Korea. We collected the spoiled dried persimmon in the refrigerator and classified them to 4 types depending on their appearances. Furthermore we isolated blacken spoilage inducing bacteria from type D of dried persimmons. Among the isolates we identified the seven blacken spoilage inducing bacteria. They are Aeromonas hydrophila DP1, Cedecea davisae DP2, Ewingella americana DP3, Flavimonas oryzihabitans DP4, Providencia rettgeri DP5, Providencia rustigianii DP6 and Serratia plymuthica DP7. Strains were identified based on their morphological, cultural and physiological properties. We also found that Ewingella americana DP3, Flavimonas oryzihabitans DP4 were the major blacken spoilage inducing bacteria during dried persimmon storage.

Sea-buckthorn fruits (Hippophae rhamnoides L.) are used in Mongolia as traditional medicine due to the health-benefits associated with its bioactive components. The purpose of this study was to investigate the chemical composition of Mongolian sea-buckthorn fruits. In terms of proximate composition, crude fat content was the highest, whereas its crude ash content was the lowest. In organic acid contents, malic acid content ( mg/g) was the highest. Free sugars were composed of sucrose, xylose, glucose and mannitol. Vitamin C and carotenoid content were 320 mg/100 g and 715.25 mg/100 g, respectively. The major fatty acids were palmitic (C16:0), palmitoleic (C16:1), caprylic (C8:0) and linoleic (C18:2) acid.
