Preservatives are additives that are added to food to keep it safe for consumption. In canned foods, preservatives are used to prevent spoilage, which is caused by the growth of micro-organisms such as bacteria, fungi, and molds.
Types of Preservatives Used in Canned Foods
Preservatives used in canned foods can be categorized into two main types: natural preservatives and chemical preservatives.
Natural Preservatives
Natural preservatives include compounds such as salt, sugar, vinegar and citric acid. These compounds inhibit the growth of micro-organisms by changing the pH or osmotic balance of the food, thus making it difficult for them to survive. Natural preservatives have been used in food preservation for centuries and are generally considered safe to consume.
Chemical Preservatives
Chemical preservatives are synthetic compounds that are added to foods to inhibit or delay spoilage caused by micro-organisms. These preservatives include sodium benzoate, potassium sorbate and sodium nitrite. Chemical preservatives have been found to be effective at extending shelf life but may also pose health risks if consumed in large quantities over a long period of time.
In summary, canned foods contain both natural and chemical preservatives which help to extend their shelf life and keep them safe for consumption. Although these preservatives are generally considered safe when consumed in moderation, it is important to pay attention to expiration dates on canned products and consume them within a reasonable amount of time after opening.
Conclusion
In conclusion, adding preservatives to canned food helps extend its shelf life and make it safe for consumption. Natural (e.g., salt, sugar) and chemical (e., sodium benzoate) preservatives can be used depending on the product’s intended shelf life and desired level of safety. Consumers should always check expiration dates on canned products before consuming them and should follow recommended storage instructions after opening them.
