In order to improve the quality of Kamju(sikhae), Korean traditional sweat fermentated rice drink, Kamju made with laboratory fermenting from both covered barley malt and that added to commercial $\alpha-amylase$ and commercial sikhae can were investigated and analyzed ad follows 1. The amylase activities in L-malt(laboraory made malt), C-malt(commercial malt) were 25,065 units, 20,498 units at $60^{\circ}C$ and when heating at $60^{\circ}C$ for one hour their heat stability was getting lower and while at $70^{\circ}C$ after 2 hours both their heat stability was under 21%. 2. The external appearance, of all samples, in beating test, flipper, springer and leaker test were excellent and good valued. On the open test of sample can, head space was 7.9~9.0mm, net weight 247~250g, 432~435g, pH 4.96-5.76, Brix 13.2~14.0 and vacuum degree was 29~35cmHg. 3. The sucrose content of sample 1~5 was 8,57~10.01% highest ammount than sample 6(0.91%) 7(0.43%) and maltose content of sample 1~5 was 0.65~1.41% lower than 6 was 7.91% and 7 was 8,36%. The good traditional flavor texture and saccharides components content of glucose of sample 1~5 was 1.09~1.51, 6(3.86%), 7(3.97%), fructose content of sample 1~5 was 0.45~0.95%, 6(2.76%), 7(2.81%), maltotriose and raffinose of sample 1~5 were 0.04~0.291, 6(0.61%), 7(2.81%), and solid content of sample 1~5(3.1~3.8) was lower than 6(10.25%), 7(10.09%). 4. The result of sensory test as measured as lemone yellow of sample 6 and milky of sample 7, and weetness, flavor, color, traditional texture and sensory value for sample 1~5(3.1~3.8) was lower degree than that for 6(4.5), 7(4.0). 5. Among the heavy metals analyzed from sample cans, tin, iron and lead content for sample 1~5 were 31.95~36.71ppm, 5.84~6.39ppm and 0.075~0.09ppm while their content of sample 6.7, tin, 32.91ppm, 32.87ppm, iron 5.51ppm, 5.41ppm and lead, 0.074ppm, 0.079ppm.
