Abstract |
Citrus junos Sieb. (ex TANAKA), which is commonly called as “Yuja” in korea, belongs to a citrus Citrus junos Sieb. (ex TANAKA), which is commonly called as “Yuja” in korea, belongs to a citrus fruit that is mainly cultivated in northeast Asia. Most food products of yuja are processed to a form of “yujachong” in korea. A table spoon of this syrup stirred into a cup of hot water makes a beverage called “Yuja tea”, which used as herbal remedy for the common cold and similar winter illness. Yuja seed takes about 15% of total weight of whole yuja fruit, and is abandon during most of yuja process. Therefore, it’s meaningful to investigate on such properties of yuja seeds and furthermore, develop certain types of processed yuja seed product.
According to proximate analysis of yuja seeds, they were composed of 10.5% water, 2.5% ash, 31.4% crude lipid, 15.3% crude protein and 40.3% carbohydrates. To obtain essential oils, yuja seeds were extracted by supercritical carbon dioxide(SC-CO2). The alcohol was added to supercritical extracted residue(yuja seed) in order to extract bioactive substances(flavonoid component, etc) . We investigated the antioxidant activity and chemical composition of yuja seed essential oil and supercritical extracted residue.
