White bread vs whole wheat bread
The synthesis of most bread is: flour, sugar, oil, yeast and liquid. Different types of ingredients will affect the nutritional value of the finished product.
The difference between whole wheat bread and white bread lies in whether whole wheat flour is used. In other words, it is the flour that brings different nutritional value to the two kinds of bread.
Whole wheat flourThe reason why it has more nutritional value is that it has undergone fewer processing procedures than ordinary flour; the fewer processing steps, the more nutritional value can be retained. Ordinary flour will remove the "germ" and "wheat bran" that are the most nutritious.
As a result, the flour used for white bread actually only contains starch and does not have many nutrients. On the contrary, the whole wheat flour used in whole wheat bread has the germ supplying a large amount of protein and minerals, and the bran is rich in vitamins and dietary fiber to aid digestion.
Is the food on the market really 100% whole wheat?
Although whole wheat flour is more nutritious, its shelf life is not as long as that of white flour, and it will go rancid after a few weeks, and the demand for use is not as high as that of ordinary flour. Therefore, there are many "whole wheat" products on the market. Just using general flour sprinkled with bran, it makes consumers think they are really eating a "whole wheat" product.
To truly qualify as a whole-wheat product stipulated by the government, whole-wheat flour itself must contain bran, germ and endosperm, and the proportions must be the same as those of the original grain. As for the product, its whole wheat content must account for 51% of the product; you can confirm its ingredients before purchasing.
How to identify
However, considering that some breads are swept away right after they are baked, and there is no time to even label the ingredients, how can you tell whether the bread is whole wheat? In fact, it is very difficult to see it with the naked eye and can only be roughly distinguished by taste.
The germ and wheat bran particles in whole wheat flour will interfere with the production of gluten, so the bread produced will have a harder and more solid texture than white bread. The best thing to do is to ask the store clerk to cut some samples to try before choosing!
How to store the bread after you buy it home?
Usually at room temperature, others will be sealed and placed in the refrigerator to freeze. On the one hand, it can extend the shelf life, and on the other hand, it is less likely to get moldy than refrigeration!
