Abstract

The present invention discloses a brown rice tea and the manufacture method; the manufacture method is that the brown rice is baked and crushed; boiled water is added and the crushed brown rice is evenly mixed, gelatinized and ground into pulp; alpha-amylase is added for enzymolysis with constant temperature; the temperature is reduced and diastase and neutral protease are added into the pulp for enzymolysis with constant temperature; the hydrolyzate is heated for enzyme deactivation treatment; centrifugal treatment is implemented on the mixture and the supernatant liquid is fetched; water is added into the supernatant liquid for dilution; and then green tea powder, L- lysine monohydrochloride, sodium acetylide or xanthan gum or guar gum, citric acid or malic acid and sodium cyclamate or aspartame are added and mixed evenly; and then the mixture liquid is homogenized and bottled; the bottled liquid is sterilized and the manufacture of drink is completed. The present invention takes the brown rice as the main raw material which is hydrolyzed with enzyme; in this way, the content of micro-molecular sugar, micro-molecular peptide and amino acid which are easy for absorption is increased and the L-lysine monohydrochloride whose content is low in the hydrolyzate of the brown rice is added to enrich the amino acids in the product; the green tea powder is added to enrich the taste and balance the nutrition; in this way, the drink also has the fragrance of baked brown rice and delicate fragrance of green tea.
