Why should the jar for storing Fried Dough Twists be vacuum-sealed

Prevent moisture from softening and lock the crispy taste: Fried Dough Twists is a dry snack with low moisture content, which is the key to keep its crispy taste. The vacuum sealing can completely isolate the water vapor in the outside air and prevent the water vapor from entering the pot and being absorbed by the big Fried Dough Twists, so as to prevent the big Fried Dough Twists from being damped, softened and sticky, and maintain the crisp texture when it is just out of the pot for a long time to avoid the bad taste.
Isolate oxygen, inhibit oxidation and deterioration: oxygen in the air is one of the main factors leading to the decline of quality of big Fried Dough Twists. On the one hand, the oil (especially unsaturated fatty acid) contained in Fried Dough Twists will oxidize with oxygen to produce a harshness and odor, which will darken the color and destroy its flavor and appearance; On the other hand, oxygen will accelerate the loss of aromatic compounds (terpenes) in Fried Dough Twists flower, make it lose its unique flavor, and also promote the growth and reproduction of aerobic microorganisms (such as mold and yeast), increasing the risk of deterioration. The vacuum environment can reduce the oxygen concentration in the tank to a very low level, inhibit the oxidation reaction and the breeding of aerobic microorganisms from the root, significantly extend the shelf life and reduce waste.
Prevent pollution and odor, and maintain pure flavor: vacuum sealing can form a closed physical barrier, which can not only isolate dust, bacteria, insect eggs and other pollutants in the external environment, avoid secondary pollution of Fried Dough Twists, and ensure food safety; It can also prevent the smell of Fried Dough Twists from leaking out of the pot, and prevent the odor of other food from outside from seeping in, so as to maintain the pure flavor of Fried Dough Twists, especially suitable for long-term storage or with other snacks.
Assisted humidity control and bacteriostasis, suitable for long-term storage: for large Fried Dough Twists flowers stored in batches or for a long time, vacuum sealing can further regulate the water activity in the tank, so that the water activity can be reduced to a range that is not conducive to the growth of microorganisms. In combination with a cool and dry storage environment, long-term storage for 1-3 months can be achieved without adding chemical preservatives, and the natural taste and quality of large Fried Dough Twists flowers can be retained to the greatest extent. This is the core reason why vacuum sealing is more advantageous than ordinary sealing.
