Recently, the topic of oyster sauce has been hot again. Many people think that the current oyster sauce is fake oyster sauce. It is “fixed” with additives. Eating it will cause cancer. Is it really that?
First, the oyster sauce is all “technology and hard work”?
To understand this issue, we need to know how oyster sauce is made, mainly three steps.
1. Take oyster meat and clean
There are many uses of oysters, some are eaten directly, some are roasted, and some are sent to oyster sauce.The method of prying open oysters is artificial and specialized, and the methods of different manufacturers are different.After taking out the oysters, you need to clean it.
2. Concentrated oyster sauce
After cleaning, sort out the oyster meat, and then send it to extract the essence, condense into oyster sauce, that is, put the oysters into the pot, and slowly cook it with the fire.After cooking for a while, remove the oyster meat and cook the remaining oyster soup at low pressure to condense oyster sauce.
3. Make up oyster sauce and add “Hex Technology”
From the concentrated oyster sauce to the oyster sauce, it is necessary to add pigment, condiments, and thickeners to the factory. After a series of processing, the oyster sauce will continue to cook in the stainless steel can.After the end, you can bottle oyster sauce.
Why should a small bottle of oyster sauce add so many “technology and hard work”?Because the cost of traditional oyster sauce is too expensive!
In the traditional process, oyster sauce, 2000 catties of oysters can only cook 150 ~ 180 catties of fuel consumption, and the price is very expensive.And the output of traditional craftsmanship is difficult to adapt to huge demand, and it is prone to supply in short supply.

3. Preservation:

Under the premise of normal dosage, it will not threaten health.
Even though the preservatives added in oyster sauce will not threaten health, but everyone still has a natural sense of rejection of preservatives, is that oyster sauce without preservatives must be good?
Nong Shaozhuang, a professor at the School of Food of Dalian University of Technology, said that the condiments such as oyster sauce are rich in nutrition and are easy to spoil and deteriorate. The purpose of adding preservatives is to prevent deterioration.
