At present, some bulk foods in supermarkets have no production date, including chocolate, candy, steamed bread and potato chips. However, not seeing the production date does not mean that there is no shelf life, because the food safety and health department has such a regulation: as long as it is food, it is necessary to indicate the production date and shelf life, and chocolate is no exception.
There is no production date on the packaging of bulk chocolate, but it is on the outer packaging box of chocolate, but the supermarket staff can't tell which box these bulk foods are in. Everyone can only judge whether the food is expired by the freshness and taste of the food.
This method is obviously unreliable, so for the sake of safety, it is the best policy for us to buy regular chocolate with quality certification and production date.
