Jin 'ao general manufacturers only study machines, but don't study pancake technology deeply enough, which has caused great confusion to many customers who buy Jin 'ao! For example, the pancakes made in Jin Ao are often moldy, hard and dry. Moldy because pancakes are high in moisture. Only by baking the moisture in the pancakes can we ensure that the pancakes are not moldy. Just because the flour is aging, we should keep the pancakes soft and not contain water. You can use multi-source foam with QS certificate, and pancakes will be soft but not hard.
