Which foods cannot have preservatives added?

Food preservatives are chemical substances added to extend the shelf life of food and prevent spoilage. Generally, preservatives should not be added to foods that naturally have a long shelf life, fresh foods, seafood, non-perishable foods, or frozen foods. If you experience physical discomfort after consumption, it is recommended to seek medical attention promptly.

1. Foods with naturally long shelf lives

Foods such as preserved fruits, honey, and dried fruits inherently have long shelf lives and do not require preservatives. Adding preservatives may compromise their natural flavor and nutritional value.

2. Fresh foods

Fresh meat, fish, eggs, and similar products are prone to bacterial growth. Proper storage and handling methods must be observed, and preservatives should not be added.

3. Seafood

Products such as dried scallops, sea cucumbers, and seaweed already contain a certain amount of salt from harvesting and processing, which provides natural preservation, making additional preservatives unnecessary.

4. Non-perishable foods

Foods such as grains and dried nuts contain high levels of starch and sugar, making them less susceptible to spoilage and eliminating the need for preservatives.

5. Frozen foods

These foods rely on low-temperature storage to inhibit microbial growth, so preservatives are not required. During freezing, water in the food forms ice crystals, a process that not only suppresses microbial activity but also helps maintain freshness and nutritional content. Common frozen foods include frozen meats, seafood, vegetables, and ice cream.

It is recommended to consume fresh fruits and vegetables, maintain personal hygiene, wash hands before meals and after using the restroom, eat fewer fried or deep-fried foods, and reduce intake of fats and calories.
