1. How long does the natto machine take to make natto
If you use a natto machine to make natto, you must pay attention to controlling the time, then the natto machine makes natto How long are beans suitable for?
Generally speaking, when the natto machine makes natto, the inoculation time is not counted. It is about 12-18 hours of fermentation in the natto machine, and no more than 24 hours. The natto bacteria are not sufficient for 20 hours. Fermentation, and prolonging the time will not help. After the fermentation of natto, it can be eaten after 12 hours in a sealed refrigerator (after-cooking at 3-5 degrees). The purpose of after-cooking is to stop the fermentation of natto bacteria and maintain the fresh taste of natto.
When using the natto machine, the production time is not fixed due to different raw materials, strains and ambient temperature. It can be set to 12 hours for the first time, and pay attention to the growth of natto bacteria. When a white sticky substance grows on the surface of natto, and the natto can pull out very long silk, it means that the fermentation has been completed. If the natto bacteria do not grow well within 12 hours, it can be extended for several hours until the fermentation is completed; record the first three fermentation times, and only need to set this time in the future.
Second, the longer the natto machine makes natto, the better?
When making natto with a natto machine, some friends worry about the fermentation Completely, it will set a longer time, so will the longer fermentation time of the natto machine have any effect on natto?
It is understood that the fermentation time of the natto machine should not be set too long. Generally, the fermentation of natto is about 18 hours, and the effective substances of soybeans are basically decomposed by natto bacteria. It will become a spore state and no longer reproduce. If you continue to ferment natto, the natto bacteria will die in large numbers because there is not enough nutrition, and at the same time, a strong ammonia odor will be produced, and the taste of natto will become unpleasant. .
3. What happens if the natto machine takes too short a time to make natto?
It takes a certain amount of time for the natto machine to make natto. If the setting time is too short If the bacteria natto has not decomposed the effective substances of soybeans, the fermentation will be incomplete, and qualified natto will not be produced. The natto produced in this way is actually not much different from ordinary soybeans.
