Conclusion

As we all know, food processing, preservation, transportation and other processes
vulnerable to external pollution of microorganisms and spoilage corruption.

Without food preservation, we are unable to preserve food for long periods of
time, resulting in a significant increase in the likelihood of famine in food
shortages, so food preservation is very important and necessary. The traditional
method of food preservation is usually dry, pickled, smoked, cellar storage, wine
stains and so on.

With the continuous development of science and technology, chemically

synthesized preservatives become one of the most important additives in the
food industry.

Therefore, in recent years, more and more food industry is abuse of chemical
synthetic preservatives to extend the shelf life of food, but through the study
found that these chemical synthetic preservatives not only affect the original
flavor of food but also the potential of human induced cancer, Teratogenic or
cause food poisoning and other security risks. So people concerns more and more

with food safety.
