Bread fries easy to age?

The bread becomes hard and the French fries are soft, which is disappointing
.
According to a report by the British "Daily Mail" on September 28, the American Chemical Society recently explained to people the reasons why bread and French fries would age, and provided some tips for solving this type of problem
.
Researchers say that moisture is a key factor in food aging
.
Bread and French fries are starchy foods, and starch molecules are hydrophilic and can absorb water in food
.
Bread contains wheat flour protein, gluten, and starch molecules (mainly including amylose and amylopectin)
.
The carbon dioxide ring is surrounded by a scaffold structure, which forms the soft taste of bread
.
At the same time, this structure can also lock in moisture
.
In the beginning, amylose molecules begin to break down and release water
.
But pullulan has a longer time to lock water, because the decomposition process of these molecules is slow
.
The moisture will slowly pass away, making the bread hard and brittle
.
And the bread shell contains hydrophilic starch, which will absorb the moisture inside the bread
.
If the bread is aged, put it in the oven and adjust the temperature to 60°C
.
The researchers said that this approach allows the bread to absorb moisture and restore its soft taste
.
If you plan to eat the cake in one or two days, you can put it in a bread box or paper bag to prevent it from aging
.
The main thing to note is to avoid using plastic bags to store bread, because it will cause moisture loss in the bread and eventually form blue-green mold
.
　　In addition, putting the bread in the refrigerator will also cause the bread to harden, and the rate of change is 6 times faster than at room temperature
.
If you want to store bread for a longer time, just store it in the freezer
.
　　As for French fries, the role of moisture is even more important
.
During the frying process, almost all the water in the French fries evaporates, so the starch in the food becomes "thirsty", prompting them to continuously absorb water from the air
.
　　The box of French fries contains nitrogen.
The probability that it will not react with moisture before opening is 86%
.
This design can prevent the fries from smelling off
.
The researchers said that once the fries start to soften, they can be placed in a microwave oven and bake at a high temperature for 30 seconds to force out the moisture
.
This method can effectively restore the crispy taste of French fries, and the taste is almost the same as the one just bought
