Multi-strain microorganism leavening agent and preparation method thereof

Abstract

The invention relates to a multi-strain microorganism leavening agent and a preparation method thereof. The preparation method comprises the steps of respectively performing strain activation and slope cultivation on bacillus subtilis, bacillus megatherium, aspergillus niger, lactic streptococci, candida utilis and corynebacterium glutamicum, mixing the six microorganism strains by weight percent, putting the mixed strains into a triangular flask, putting the triangular flask into a shaker, cultivating at 28 DEG C for 2-3 days, controlling the pH to be 6.5-7.0 so that the strain content reaches 0.6-0.8 billions per milliliter, thus obtaining the multi-strain microorganism leavening agent. By use of the multi-strain microorganism leavening agent prepared from the six specific microorganism strains selected according to the characteristics of navel oranges, the quality of the navel oranges can be improved, and the yield of the navel oranges can be increased by 10-15 percent, so that a demand in the highest price stage can be met.

Description

technical field [0001] The invention belongs to the field of biological materials, and relates to a multi-strain microbial starter and a preparation method thereof. Background technique [0002] Since navel oranges were planted in the 1970s, the Gannan navel orange industry has experienced a difficult and tortuous development path from scratch. Due to the special geographical environment and rich rare earth, Gannan navel oranges are not only delicious, sweet and juicy, but also play a role in health care. However, there are still situations where production is in short supply when prices are at their peak. In addition, although the juice yield rate of Gannan navel oranges is relatively high compared to other domestic navel oranges, it is still not up to the level of Brazil and other countries. For example, the juice yield of Brazilian industrial oranges can reach more than 60%, while the juice yield of Gannan navel oranges can only reach about 40% at most, and the solids l...
