salmon meat is compact, delicious, rich in oil, pink and elastic, which is deeply loved by many people. However, it is mainly distributed in the north of the Pacific Ocean and the north of Europe, Asia and America. It is difficult for us to eat fresh salmon, so vacuum packaging salmon has become the main way of preservation. Experts from Shenzhen Shengfeng Packaging Machinery Co., Ltd. reminded that vacuum packaged salmon need to be unpacked before thawing to prevent bacterial contamination
vacuum packaging, also known as oxygen reduction packaging (ROP), is used to prevent moisture loss. The reason for using this kind of packaging is that it can keep the fish in the refrigerator for a longer time, reduce the emission of odor, and the characteristics of the fish will not change significantly, which may deteriorate the fish. Packed in vacuum, the air is pumped out of the bag, so that the package is completely sealed
vacuum packaged fish is delicious and high-end food, but what should we pay attention to? After thawing vacuum packaging, Listeria and botulinum are easy to appear
Botox is an anaerobic bacterium (meaning that they survive in an anoxic environment). They combine into steamed stuffed buns, which enables them to survive under adverse conditions. When conditions are right, the spore will evolve into a plant cell, which can produce a deadly toxin. This toxin will cause botulism and life-threatening. For details, please click
in order to ensure that there is no toxin, Michigan State University recommends that food, such as fish, be vacuum packed at a suitable temperature (no oxygen). Botox produces toxins much faster at high temperatures than at low temperatures. As the storage temperature rises to 38 degrees Fahrenheit (3.3 degrees Celsius), the time required to produce toxins is significantly reduced. Many household refrigerators already have temperatures in excess of 38 degrees Fahrenheit (3.3 ° C). In addition, if the fish is thawed in cold water, the temperature will also exceed 38 degrees Fahrenheit (3.3 ° C)
the label of vacuum packaged fish products will say: keep the product refrigerated before eating or thawing in the refrigerator, or unpack the fish immediately before or after thawing. When thawing the vacuum packaged fish, open the package, the fish will be exposed to oxygen, and the spores will not form plant cells that produce toxins.

Listeria is a bacterium that can corrode food. If it occurs, it may cause a series of serious diseases and pose a great risk to the following groups: the elderly, pregnant women and newborns who have low immunity. Unlike other bacteria, Listeria can grow and reproduce in food in the refrigerator.
