A method for preparing extract, concentrate and distillate using green barley or buckwheat powder coated with the specific flavor of green barley or buckwheat is provided to take the extract, concentrate and distillate mixed to food and drink or use the extract, concentrate and distillate as a food and drink additive. A preparation method of extract, concentrate and distillate using green barley or buckwheat powder coated with the specific flavor of green barley or buckwheat comprises: (i) a first process of washing green barley or buckwheat; detoxifying, sterilizing and neutralizing the washed green barley or buckwheat by soaking it in water containing acetic acid, citric acid and salt; spraying liquor on the sterilized green barley or buckwheat and then drying it for a water content to be less than 5%; firstly crushing the dried green barley or buckwheat; putting the crushed green barley or buckwheat into a parching machine, spraying liquor having an alcohol content of 14~20% on the green barley or buckwheat, rotating the machine at a velocity of 40~50rpm at an inner temperature of 70~100°C, sealing up the machine when the specific flavor of the green barley or buckwheat gets vaporized, setting the inner temperature to 120~200°C, and rotating the machine at a velocity of 200~250rpm to coat the green barley or buckwheat with its specific flavor; and processing the green barley or buckwheat coated with its specific flavor into granules or fine powder; and (ii) a second process of adding 10~15% of the green barley or buckwheat powder obtained from the process (i), 1.5~2.5% of liquor, 0.5~1.0% of salt, 0.5~1.0% of acetic acid and 0.5~1.0% of citric acid to water at 35~45°C, based on the total weight of the water, to obtain an extract from the green barley or buckwheat powder; and concentrating and distilling the extract at low temperature under vacuum to obtain a concentrate and a distillate. In the first process, the each amount of the acetic acid, citric acid and salt added to water is 0.2~0.5wt%, 0.2~0.5wt% and 0.1~0.4wt%, based on the total weight of the water, and the amount of the liquor sprayed on the green barley or buckwheat is 0.3~0.5wt%, based on the total weight of the green barley or buckwheat. |
