Electric Kettles Heating Coffee Sparks Food Safety And Taste Controversy

Recently, the question of whether or not to reheat coffee in an electric kettle has sparked widespread discussion on social media. Some consumers believe that electric kettles, due to their speed and convenience, offer a simple solution for cooling coffee. However, industry experts and coffee professionals disagree, sparking a debate over food safety and taste preservation.

According to home appliance industry technicians, the heating mechanism of electric kettles is primarily designed for plain water. Directly heating coffee containing oils and fine powders can easily leave residue at the bottom of the kettle, making it difficult to clean and potentially affecting the lifespan of the device. Furthermore, prolonged heating can cause some of the coffee's aromatic compounds to evaporate, resulting in a bitter taste.

Food safety experts point out that if coffee is left at room temperature for extended periods, especially for more than four hours, bacteria may grow inside, and reheating does not completely eliminate the risk. Therefore, consumers are advised to brew and drink coffee immediately, rather than relying on reheating.

Nevertheless, some home appliance brands have recognized consumers' need for coffee heating and are developing small devices with low-temperature constant temperature and beverage heating functions to replace direct heating methods with Electric Kettles. Industry analysts believe that the introduction of these specialized functional products will, to a certain extent, enhance the safety and experience of beverage preparation and consumption.

Industry analysts predict that with the diversification of home beverage consumption scenarios, the market will likely see an increase in innovative appliances tailored to specific heating needs for beverages like coffee and milk tea, gradually forming a new product segment.
