10 methods to properly and safely store food in the refrigerator:

1. Classify food before placing it in the refrigerator: Separate fresh foods, cooked foods, fruits, and vegetables to prevent cross-contamination and ensure optimal storage conditions for each type.

2. Safely package food: Use airtight containers or zip-lock bags to store food, preventing bacterial contamination and preserving freshness.

3. Avoid overloading the refrigerator: Overfilling can obstruct air circulation, reducing cooling efficiency and potentially leading to food spoilage.

4. Adjust the storage temperature appropriately: Maintain the refrigerator temperature between 1-4°C for fresh foods and around -18°C for frozen items to ensure optimal preservation.

5. Regularly clean the refrigerator: Periodic cleaning, approximately every 3-6 months, helps eliminate bacteria, mold, and unpleasant odors, maintaining a hygienic environment.

6. Freeze food properly: For long-term storage, place food in sealed bags or containers before freezing to preserve quality and prevent freezer burn.

7. Organize food intelligently: Arrange foods systematically, placing items with nearer expiration dates at the front to ensure timely consumption and reduce waste.

8. Handle strong-smelling foods carefully: Store foods with strong odors, such as dried fish or fermented products, in sealed containers to prevent odor transfer to other foods.

9. Use refrigerators with suitable preservation functions: Modern refrigerators often come with features like soft freezing compartments or humidity-controlled vegetable drawers, enhancing food preservation.

10. Do not store food in the refrigerator for too long: Even under refrigeration, prolonged storage can lead to nutrient loss and potential spoilage; consume foods within recommended timeframes.
