1. What kind of beans are better for homemade natto in the natto machine?
The natto machine uses soybean fermentation to make natto. When making natto, What kind of beans are better to use? Many friends may not know much about them, so I will introduce them to you below.
In fact, in theory, all beans can be put into the natto machine to make natto, because the “food” of natto bacteria is mainly protein, and in theory, beans containing protein can be made. Natto, but when choosing, the soybean with the highest protein content (above 38%) is usually preferred.
In addition to soybeans, other beans such as black beans have higher protein content, but the skin of black beans is thicker, and the fermentation is not as sufficient as soybeans; for example, red beans, mung beans, chickpeas, etc. It contains more starch and lower protein content, so it is not ideal for making natto.
Second, whether to use large soybeans or small soybeans to make natto with a natto machine
The main use of natto machines to make natto is soybeans, but soybeans There are also large-grained soybeans and small-grained soybeans, so what kind of soybeans do natto machines use?
Generally speaking, it is better to use small-grain soybeans when making natto in a natto machine, because the protein content of small-grained soybeans is higher than that of large-grained soybeans. Using small-grained soybeans to make natto, soybeans are fermented better. , brushed more. Of course, large-grained soybeans can also be made into natto, and because small-grained soybeans are low in yield, and a large part of them are exported, there are very few small-grained soybeans in the domestic market, so they are generally made from large-grained soybeans.
Third, what kind of bacteria do natto machines use to ferment natto
When using a natto machine to make natto, in addition to considering the choice of beans, Another raw material – the selection of strains is also very important. The quality of strains is not good, and the fermented natto will also be poor. So what kind of strain is good for natto machine to make natto?
The natto machine usually uses special natto bacteria. Natto is passed down from Japan, so this strain is more commonly used. After a long-term market test, there are mainly three The major strains are “Takahashi mushroom”, “Naruse mushroom” and “Miyagi wild mushroom”.
In addition to the selection of strains, attention should also be paid to the purity of strains. Bad; if mixed with miscellaneous bacteria, not only cannot make qualified natto successfully, but it may be harmful to eat.
