Can I still eat expired Delfi chocolate if it hasn't been opened?

Generally speaking, if a DeFei chocolate product is unopened but has passed its expiration date, it should not be consumed. The detailed explanation is as follows:

Even if unopened, expired DeFei chocolate may experience deterioration in taste, the development of off odors, loss of nutritional components, or the growth of bacteria, mold, and other microorganisms. Furthermore, DeFei chocolate cannot guarantee its original quality and safety after expiration. The fats contained within may become rancid, with increased peroxide values leading to excessive oxidation of oils and fats. Consumption of such products may cause indigestion, gastrointestinal discomfort, or even food poisoning.

To ensure food safety and health, it is recommended to follow the expiration date guidelines and consume DeFei chocolate within its shelf life. If unsure about the safety of the product, a safer approach is to discard it in order to avoid potential health risks.
