Table 1 Physical and chemical index project indicators Total sugar content (sucrose + reducing sugar)/(g/100g) ≥ 98 Sucrose content (g/100g) ≥ 97.6 Weight loss on drying/(g/100g) ≤ 0.4 Water-insoluble impurities/(mg/ kg) ≤ 50 Color value (IU) ≥ 1200 Calcium/(mg/kg) ≥ 20 Iron/(mg/kg) ≥ 5.0 Zinc/(mg/kg) ≥ 0.5 Total amino acids/(g/100g) ≥ 0.02 total Flavonoid a/(mg/kg) ≥ 10 and total phenolic a/(mg/kg) ≥ 30 a are the limit indicators. Premium golden sugar should have one (or more than one) indicator that meets the requirements.
