Problems solved by technology

Because this method of selecting barley green can not extract all barley green in barley green shoots, caused the great waste of barley production raw material; Simultaneously, owing to need to add many chemical additives in the extraction process of barley, As a result, the produced barley chlorophyll metal ions seriously exceed the standard, which will cause greater harm to the human body after eating; in addition, the extraction process of barley chlorophyll is complicated, the equipment investment is large, and the production cost of barley chlorophyll products produced very high

Abstract

The invention relates to a preparation process of a barley seedling tender leaf tea, comprising the following steps of: (1) selecting the fresh barley seedling tender leaves with the lengths of 25 to 30 cm from the barley seedlings which are not applied and polluted by chemical fertilizers and chemical pesticides; (2) after removing the impurities of the fresh barley seedling tender leaves in the step (1), rinsing by using water; (3) sequentially soaking the rinsed fresh barley seedling tender leaves in an H2O2 solution with the concentration of 2.5%, eluting by using clear water and dewatering by vibrating to obtain clean barley seedling tender leaves; (4) cutting the clean barley seedling tender leaves obtained in the step (3) into tender leaf segments with the lengths of 1.5 to 2 cm; and (5) freeze-drying the tender leaf segments obtained in the step (4) in a vacuum state to obtain the barley seedling tender leaf tea. The process is simple, can ensure that heat-sensitivity nutrient substances in the product are not decomposed and lost, and reserves the nutrient constituents in the barley seedling tender leaf tea to the maximum, thereby ensuring that the barley seedling tender leaf tea has uniform color and luster.

Description

technical field [0001] The invention relates to a production method of a natural nutritional health product, in particular to a preparation process of young barley young leaf tea. Background technique [0002] The chemical structure of barley chlorophyll in young barley young leaves is very similar to the hemoglobin of human red blood cells. After drinking, it can help make red blood cells and effectively purify the blood. Therefore, it is commonly known as "green blood" and has become an increasingly popular food abroad. Fashion health products. Young barley is currently recognized as the best raw material for the production of barley greens at home and abroad. People usually wash the barley greens, blanch them quickly and instantly, and then dry them to extract barley greens. Because this method of selecting barley green can not extract all barley green in barley green shoots, caused the great waste of barley production raw material; Simultaneously, owing to need to add m...
