National Food Safety Standard – Edible Alcohol1 ScopeThis Standard is applicable to the edible alcohol.2 Terms and Definitions2.1 Edible alcohol The water-contained alcohol taking cereals, potatoes, molasses or other edible crops as the main raw materials; refined through fermentation and distillation; and used for the food industry.3 Technical Requirements3.1 Requirements for raw materials The raw materials shall conform to corresponding product standards and relevant provisions. 3.2 Sensory requirements The sensory requirements shall conform to the provisions of Table 1. Table 1 -- Sensory Requirements Items Requirements Test Methods Appearance Colorless and transparent Take appropriate amount of specimen into the beaker; observe the color and luster state under the natural light; it shall be transparent, and without visible foreign matters Odor Have the inherent aroma of the ethanol, without abnormal odor Use plug cylinder to take 10mL of specimen; add 15mL of water; cover the plug, mix evenly. Pour into 50mL small beaker; smell the odor. Taste Pure, slightly sweet, no smell Take 20mL of specimen into 50mL volumetric flask; add 30mL of water; mix evenly; then pour into 100mL beaker; place into 20°C water bath; taste it after it is at constant temperature 3.3 Physical and chemical indicators A.1.2.4 Iodine standard titration solution . when using, accurately dilute the 0.1mol/L iodine standard solution for 10 times. A.1.2.5 Starch indicator (10g/L). prepare as per GB/T 603. A.1.2.6 Sodium bicarbonate solution [c(NaHCO3)=1mol/L]. A.1.3 Absorb 15.0mL of specimen into 250mL iodine flask; add 15mL of water, 15mL of sodium bisulfite solution, 7mL of hydrochloric acid solution; shake evenly; stand for 1h; take out; use 50mL of water to wash the stopper; titrate with iodine standard solution; when it is close to the end point, add 0.5mL of starch indicator; change the iodine standard titration solution to titrate till the light blue and purple appears (not counting). Add 20mL of sodium bicarbonate solution; slightly open the stopper; shake for 0.5min (colorless); use iodine standard titration solution to continue to titrate till the blue and purple turns to the end point. Meanwhile, do the blank test. A.1.4 Result calculation The aldehyde content in the specimen shall be calculated as per Formula (A.1). X – aldehyde content (calculated by ethylal) in the specimen; in mg/L; V1 – volume of iodine standard titration solution consumed by specimen, in mL; V2 – volume of iodine standard titration solution consumed by blank, in mL; c – concentration of iodine standard titration solution, in mol/L. 0.022 – ethylal mass expressed in g, that is equivalent to 1.00mL of iodine standard using solution . The results shall retain an integer. A.1.5 Precision The difference between two independent tests performed under repeatability conditions shall not, if aldehyde content is >5mg/L, exceed 5% average value; if the aldehyde content is≤5mg/L, it shall not exceed 13% average value.
