What is fermentation and what is brewing, and the differences and connections between them.

Brewing refers to wine, soy sauce and vinegar which are naturally fermented from grain.

fermentation refers to the process in which people prepare microbial cells themselves, or direct metabolites or secondary metabolites with the help of microbial life activities under aerobic or anaerobic conditions.

Contact:

1. Brewing includes the steps of fermentation, and it is made by fermentation (wine, vinegar, soy sauce, etc.).

difference: different ways:

1. It means organizing and processing some original materials to make them produce new things.

2. In the absence of exogenous hydrogen receptors such as oxygen, the reducing force [H] generated by substrate dehydrogenation is directly accepted by an endogenous intermediate metabolite without being transmitted by respiratory chain, so as to realize the horizontal phosphorylation capacity of substrate.

Extended information:

Solid-state fermentation was adopted, and a certain amount of rice husk, sorghum husk and chaff were added as loosening agents. After boiling and cooling, the raw materials and loosening agent are mixed with yeast or yeast for saccharification, fermented in a cellar or a vat, and then mixed with the raw materials and loosening agent for distillation. Distill the wine and cook the new material.

A part of distiller's grains is discarded, and then blended again, fermented, distilled and cooked, and so on. The distilled wine is aged in the wine cellar and blended before bottling.

The flavor types of liquor can be divided into five types: faint scent, strong scent, maotai scent, rice scent and complex scent.
