초록

The Sasa quelpaertensis Nakai is a white band on the edge of the leaf, the branch is not split, the stem is small, and the shape of the node is different from that of the inland bamboo (Sasa borealis Makino).
It is known as a plant that is highly likely to be used as a resource plant. Various efficacy studies such as antioxidant, anti-obesity, antibacterial and antidiabetic activities have been conducted and developed as functional cosmetics and beverage products. Unfortunately there is little research on the suitability of the product.
In order to use S. quelpaertensis as a raw material for food or health functional food, S. quelpaertensis leaves were collected monthly for one year to prepared 70% ethanol extract(SQEP) and water extract(SQWP). After, the content of index component(p-coumaric acid) in SQEP and SQWP was analyzed by HPLC. For the study of the processing properties, the SQWP was prepared considering the content of the index component and extraction yield(%). Also, the stability of index component according to pH(2.5, 4.0, 6.0, 8.0, 10.0) condition and stability of index component according to temperature condition(25℃, 35℃, 40℃) were studied.
Through this process ability(properties) study, we suggest that the SQWP may be used as a product material of health functional foods.
