What type of container should NOT be used to store acidic foods?

Acidic foods can react with certain materials, leading to the leaching of harmful substances into the food, which can compromise food safety and flavor. Metallic containers, especially those made from reactive metals such as aluminum and copper, should not be used for storing acidic foods. When acidic foods are stored in metallic containers, a chemical reaction can take place that may result in a metallic taste, discoloration of the food, and even the potential for toxicity.

In contrast, plastic, glass, and wood do not react with acidic foods in the same way. Plastic containers are often used for food storage and are generally safe, provided they are marked as food-safe. Glass containers are non-reactive and provide an excellent barrier to outside elements, making them ideal for storing acidic foods. Wood, while it can absorb some liquids and flavors over time, does not react with acids in a way that poses any significant risk to food safety.

Choosing non-reactive containers for acidic foods is essential in maintaining both the safety and quality of the stored food.
