What is the bad smell in the production process of soybean products equipment?
As we all know, there is a very complicated process to make soy products. Each step needs to be handled firmly to produce a piece of high-quality tofu, but what most people may not know is that in the first step of soybean pretreatment, soybean products will volatilate some undesirable odor and harmful ingredients. They can largely determine the success or failure of the final soy product in the first step. What are these unpleasant smells? Where did they come from? Today, Shanghai Wangxin will tell you the secret of these bad smells.
There are three kinds of unpleasant odors produced in the mechanical production of soybean products. One can smell directly through the olfactory organs: for example, the grassy flavor of soybeans is emitted by n-hexal; The second is bitterness, which can be tasted through the gustatory organs; The third type is only the most important one is the odor brought by the oxidation of unsaturated fatty acids. Unsaturated fatty acids such as linoleic acid and linolenic acid in soybeans are oxidized under the action of fat oxidase, resulting in the smell of beans.
If it sounds incredibly complicated, don't worry too much. There are ways to deal with these three types of unpleasant smells. Controlling unsaturated fatty acids such as linolenic acid and fat oxidase is key to this problem.
The most common way to do this is to deactivate fat oxidase, which is heating. However, heat treatment also has the disadvantage of denaturing proteins, so it is necessary to carefully balance the relationship between the two.
Generally speaking, use 100 degrees of boiling water and heat for three to five minutes.
Of course, there are other ways to do this than to heat it up. For example, by masking the smell of beans, adding sugar to the product to neutralize the bitter taste, or adding condiments such as soy sauce to mask the smell of beans and improve the flavor of the product. The addition of chemical additives in the production process of soybean products is also a kind of method, the use of chemical additives to decompose these undesirable odor components, but also to ensure the elimination of odor.
Shanghai Wang Xin as a professional soybean products machinery manufacturer is willing to explain more soybean products knowledge, bring more soybean products culture.
