food packaging bags will bulge, which can be divided into physical swelling bags and bacterial swelling bags

physical swelling is mainly caused by the vacuum degree in the bag can not meet the requirements during vacuum sealing, and bacterial swelling is caused by incomplete sterilization. The inedibility of bulging bags refers not to the risk of preservatives, but to the risk of deterioration. After the food goes bad, microorganisms will decompose the organic matter in the food to produce gas, so it will reduce the volume of solid and increase the gas, which is commonly seen as “bulging bag”

solution

the reason of food itself needs the joint control of food manufacturers and sellers. As a manufacturer, the food production process should be strictly controlled, such as the control of moisture, oil content and other components of the food itself

for the problem of bulging of outer packaging, food enterprises should set up complete and professional solutions, effectively identify suppliers and guide the improvement of packaging process from the quality of incoming packaging materials, so as to avoid food problems such as bulging caused by unqualified packaging quality

food bags will bulge because the food has gone bad

nature and reason of bulging bag:

bulging bag is a common problem in food packaging, which is generally the appearance of food deterioration

the inedibility of bulging bags refers not to the risk of preservatives, but to the risk of deterioration. After the food goes bad, microorganisms will decompose the organic matter in the food to produce gas, so it will reduce the volume of solid and increase the gas, which is commonly seen as “bulging bag”

the most fundamental cause of food packaging swelling is microbial reproduction or unqualified packaging materials. When in an environment with appropriate oxygen and moisture, microorganisms will multiply in food and release carbon dioxide gas, resulting in bag swelling

food is decomposed by microorganisms, that is, it goes bad in daily life, and chemical reactions occur to produce a certain gas. When the original storage space is not enough, there are bulging bottles and bags

less than 1 week after bagging, the drum is round
