Abstract
In this article, we took malt, brown rice, waste beer yeast as raw materials, using biological technology to enrich γ - Aminobutyric acid, and directional enzyme digestion technology to get the required sugar source and protein source, through the ratio research to control the maillard reaction, and the continuous microwave vacuum drying technology to produce functional malt extract. Through single - factor experiments, the directional degradation parameters of malt were studied, and the best reaction conditions were decided as followings, the protease addition amount was 0. 2% , at temperatur 50℃, reaction for lh; and the amylase addition amount was 0. 2% , at temperature 60℃ , reaction for lh. γ -Aminobutyric acid can be enriched by promoting the activity of glutamic acid decarboxylase catalase in the brown rice, and the contents can be raised by adding VB6 and calcium sulfate. The conditions of accelerating beer yeast autolysis were also studied as followings : pH6, the addition of NaCl was 0. 8% , at temperature 50℃ and extraction for 4. 5hs.关键词
