Musa paradisiaca enzyme capable of tranquilizing mind and strengthening stomach and preparation method therefor

The invention discloses a musa paradisiaca enzyme capable of tranquilizing mind and strengthening stomach and a preparation method therefor. The musa paradisiaca enzyme is prepared from the following raw materials in parts by weight: 400-500 parts of musa paradisiaca, 100-200 parts of crataegus pinnatifida, 60-100 parts of white granulated sugar, 300-500 parts of sterile water and 30-60 parts of leaven. The preparation method comprises the steps: (1) pretreating the raw materials; (2) closing and sterilizing ferments, then, inoculating the leaven to the ferments, carrying out natural fermentation at the temperature of 25-35 DEG C, and completing fermentation until no new bubble is produced; (3) filtrating and homogenizing fermentation liquor, thereby obtaining the musa paradisiaca enzyme product. According to the musa paradisiaca enzyme capable of tranquilizing the mind and strengthening the stomach and the preparation method therefor, the obtained product not only reserves the original nutritional ingredients of musa paradisiaca and crataegus pinnatifida, but also has rich enzymes, mineral substances, vitamins, microbial secondary metabolites and the like; the product has multiple nutritional and healthcare effects such as stimulating appetite and promoting digestion, loosening bowels to relieve constipation, eliminating restlessness and quenching thirst, lowering blood pressure and blood fat, resisting oxidation, resisting aging and the like; the product is delicate in taste, rich in fruity fragrance and tasty in sourness and sweetness.
