oxygenation of food vacuum bags-ag旗舰厅
with the popularization of food vacuum bag and the development of supermarket, its application scope will be more and more extensive, and some will gradually replace hard packaging.
in addition to inhibiting the growth and reproduction of microorganisms, the other important function of vacuum deoxygenation is to prevent food oxidation, because there are a large number of unsaturated fatty acids in oily foods, which are oxidized by oxygen, making food taste and deterioration. in addition, oxidation also causes the loss of vitamin a and vitamin c, and the effect of oxygen on the unstable substances in food pigments makes the color darker. therefore, deoxygenation can effectively prevent food deterioration and maintain its color, aroma, taste and nutritional value.
