Haitian Oyster Sauce is mainly composed of juice extracted from oysters, and some thickening agents, salt, essence and other foods are added. The reason why it has the taste of oysters is because a small amount of oyster juice is added. Therefore, although Haitian oyster sauce is made of oysters, there will be other additives in it.

Haitian oyster sauce is thick and semi-fluid when poured out. So when you buy Haitian oyster sauce in the supermarket, you can shake the oyster sauce bottle. If the oyster sauce inside is attached to the bottle, then this Haitian oyster sauce is authentic. But if the oyster sauce inside doesn't stick to the bottle, it's probably not genuine.

Matters needing attention in oyster sauce storage

1, temperature: oyster sauce should be stored in a cool and dry place to avoid direct sunlight and high temperature. If it is unopened, it can be stored at room temperature, usually for 1-2 years. If it has been opened, it should be kept in the refrigerator, usually for 3-6 months.

2. Container: Oyster sauce should be kept in original glass bottles or plastic bottles, and other containers should not be used instead to avoid pollution or deterioration. Use a clean spoon or chopsticks when using, and don't lick the bottle mouth with your fingers or tongue to avoid bringing bacteria or saliva.

3. Status: During storage and use, the color, smell and taste of oyster sauce should be checked regularly. If abnormal phenomena such as peculiar smell, discoloration, mildew and caking are found, they should be stopped immediately and scrapped.
