Embodiment 1
[0020] A preparation method of glutathione-rich nucleic acid yeast powder, the yeast powder is rich in glutathione and flavor nucleotides, the mother liquor after glutathione extraction is pretreated, and then mixed with fresh nucleic acid yeast, Obtained through enzymolysis and drying, the preparation method of the glutathione-rich nucleic acid yeast powder is carried out as follows:
[0021] (1) Pretreatment of glutathione extraction mother liquor: add sodium sulfide at 0.5Kg / ton mother liquor, stir and react at room temperature for 10 minutes, then adjust mother liquor pH to 5.6 with barium hydroxide, and stir for 30 minutes to ensure full reaction between barium hydroxide and mother liquor ;
[0022] (2) Settling of the mother liquor: step (1) send the well-reacted mother liquor to the settling tank for natural settlement for more than 20 hours, then the supernatant or suction filtration or plate and frame filter to fully remove impurities for use;
[0023] (3) Collect fr...
