  • Endorcarp inhibited the embryo growth of ginseng seeds. This inhibition is not due to impermeability to water, but is probably caused by mechanical resistance. The embryo growth rate was enhanced by endocarp injury by soaking for 10 to 30 minutes in 2.5% solution of sodium hydroxide. But sulfuric acid did not affect on the embryo growth of ginseng seed.

  • To evaluate the quality difference between rice starch syrup Kochujang (RSSK) and rice flour Kochujang(RFK), moisture content, pH, titrable acidity, reducing sugar, amino nitrogen and color were measured for 90 days. Moisture content was no great difference between samples and was slowly increased during aging. pH of RSSK was 6.03 and that of RFK was 5.94 after mashing. And it was slowly decreased during aging. Titrable acidity was increased with no great difference between RSSK and RFK. Reducing sugar content of RSSK and RFK was 17.0% and 5.8% after mashing respectively. Reducing sugar content was increased till 40 days, but was decreased thereafter. Amino nitrogen content of RSSK was 123.6 mg% and that of RFK was 93.0 mg% after 20 day aging. Lightness of RSSK was higher than that of RFK, but redness was similar between RSSK and RFK.
