Sik-Hye is a korean traditional soft drink made of hard steamed rice, rice or glutinous rice, fermented with barley sprouts oil. It is produced by adding water and sugar during the process of fermentation. Because it is widely known to the public, many giant corporations sell it in the OEM system which is linked with small companies. This report will analyze the technical and hygienical problems and on improving its quality. Moreover, it will focus on increasing economical efficiency of an enzyme. It is expected that this report will give a basic idea on developing this boundless industry and will contribute to the growth of other related korean traditional soft drinks in the industry as well.

This study was conducted to evaluate the effects gamma irradiation on physicochemical and nutritional properties of gelatinized starch solutions to select cereal for patient fluid food. Gelatinized cereal solutions were prepared with wheat (GWS), rice (GRS), waxy rice (GWRS), and waxy maize (GWMS) by heating at 100℃ and subjected to gamma-irradiation at doses of 10, 20, and 30 kGy. GWRS and GWMS showed significantly higher viscosities than GRS and GWS. The viscosities of cereal solutions were decreased as irradiation dose increased, and the reduction of viscosity by irradiation was highest in GWRS showing more than 99% reduction with 20 or 30 kGy irradiation. Contrary to viscosity, blue values of GWS and GRS were higher than those of GWMS and GWRS. In FT-IR spectrum, the bands of water absorption and O-H stretching were decreased as irradiation dose increased. Blue values of the gelatinized cereal solutions were decreased by irradiation, but no differences were observed among irradiation doses. Gamma irradiation increased the content of slowly digestible starch (SDS) of GWRS, while reducing rapidly digestible starch (RDS) of GWRS, yet it did not affect in vitro starch digestibility of GRS, GWS, and GWMS. These results of this chapter may provide basic information on the changes in physicochemical and nutritional properties of gelatinized cereal solutions by gamma irradiation.
