  • Shinuncho(Angelica keiskei koidz)sulgi is a kind of steamed rice cake by an earthenware steamer. I made Shinuncho-sulgi samples with different amounts of Angelica keiskei koidz - powder and different types of sugars (sugar or honey). The more Angelica keiskei koidz powder it has the bitter it tastes but the lower sweetness, moistness and chewiness it has. Samples with honey have higher sweetness, moistness and chewiness but lower bitterness and after-swallowing than ones with sugar. Color is Shinsuncho-sulgi with $3\%$ of Angelica keiskei koidz - powder and honey has been judged to have the best quality. Flavor and Overall-acceptability are Shinsuncho-sulgi with $2\%$ of Amge;oca keiskei koidz - powder and honey has been judged to have the best quality. The more Angelica keiskei koidz powder it has the higher hardness but the significantly cohesiveness, springiness, gumminess, and chewiness it has. Samples with honey have higher hardness, springiness, cohesiveness, gumminess and chewiness, but lower adhesiveness, than ones with sugar. The moisture content of Shinsuncho-sulgi is $35.89\~37.08\%$. Samples with honey have higher b-value but lower L-value and a-value than ones with sugar. Based on the results of the study, the best ratio of ingredients is as follow non-glutinous flour 196g, Angelica keiskei koidz powder $2\%$ (4g), honey 35ml, salt 2g, water 20ml and $37.08\%$ of moisture content.

  • For the purpose of improving hygienic quality of dried-Angelica Keiskei Koidz powder, the effect of ozone treatment and gamma irradiation on the microbial decontamination and physicochemical properties were investigated. Gamma irradiation at 5 to 7.5 kGy resulted in sterilizing total aerobic bacteria, molds and coliforms below detective levels, while ozone treatment for 8 hours up to 18 ppm did not sufficiently eliminate the total aerobic bacteria of the sample. The physicochemical properties of the sample were not changed by gamma irradiation up to 7.5 kGy, whereas, ozone treatment caused remarkable changes in pH, TBA value, chlorophyll, carotenoid and fatty acid compositions. Therefore, this investigation demonstrated conclusively that gamma irradiation was more effective than ozone treatment for decontaminating and sterilizing the dried-Angelica Keiskei Koidz powder, with minimal effect on the physicochemical properties analyzed.

  • For the purpose of improving hygienic quality of health-foods, sterilization effects of ${\gamma}$-ray and ozone on microoganisms associated with food cultured in the media and contaminated in Angelica keiskei powder were investigated. Ozone was immersed in water and sprayed in air, on the concentration of 3 mg liter-1 at an air flow rate of 5 liter min-3. Test strains cultured in the media completely inhibited by ${\gamma}$-ray at irradiation doses of 0.25~2 kGy. In the case of ozone, test bacteria inactivated after treatment of 10~20 minutes, but test mold, Aspergillus flavus was not effective. Strains contaminated in Angelica keiskei powder completely inhibited by ${\gamma}$-ray at irradiation doses of 2.5~7.5 kGy. However, when the powder was sprayed with ozonized air for 10hours, Bacillus subtilis and Staphylococcus aureus among five strains were eliminated.
