Using food storage boxes to preserve food in the refrigerator helps maintain freshness and reduces bacterial contamination. Below are 6 safe and suitable ways to select food storage boxes for the fridge. Let's explore together!
1. Choosing Refrigerator Food Storage Boxes Based on Material
The primary criterion for selecting food storage boxes for the refrigerator is that the material of the box must be safe, free from toxins, durable, and heat-resistant. It also depends on factors such as the type of food and whether it's for storing in the cool or freezer section.
For the Cool Section: Most materials of food storage boxes can be used for the cool section. However, to ensure health safety, avoid purchasing low-quality containers or single-use plastic containers. It's best to use plastic boxes such as PP, HDPE, LDPE, which are cost-effective, safe, and durable.
For the Freezer Section: Choose boxes made of materials that don't degrade at low temperatures or pose any health risks, such as PP plastic. Avoid using glass boxes in the freezer as they may crack.
2. Suitable for Both Freezer and Cool Sections
Choosing containers that can be used for both the freezer and cool sections is one of the key criteria for better food preservation flexibility. Containers with this feature are not only extremely convenient but also cost-effective, optimizing kitchen storage space.
3. Secure Rubber Seal
Opting for containers equipped with a secure rubber seal ensures a tight seal for food, preventing odor mixing with other foods in the fridge and avoiding unpleasant odors. Additionally, a tight seal lid also prevents the infiltration of harmful bacteria.
4. Ventilated Lid
Food containers with ventilated lids are very convenient for heating food in the microwave. When heating food, you simply need to open the vent to release excess air from the container, preventing pressure build-up that can cause bulging or bursting of the container.
5. Heat-Resistant Containers
Opt for food containers with excellent heat resistance to store food in the fridge and also be able to hold hot food or reheat meals in the microwave. When purchasing plastic food containers, check the information on the packaging to know the temperature resistance level. Containers safe for both the freezer and microwave have a heat resistance range from -20°C to 140°C.
6. Select Containers with Appropriate Capacity
Below 500ml: This capacity is suitable for users to store rice, soup when going to work, school, or processed foods in small quantities.
From 500ml - 1 liter: This capacity is suitable for storing fruits, nuts,... for 1 to 2 people.
Above 1 liter: Containers with a capacity of over 1 liter are suitable for storing fresh foods in the fridge, especially large-sized items such as meat, filleted fish,...
7. Important Considerations When Using Food Storage Containers in the Fridge
Always close the container lid when storing food in both the freezer and cool sections to limit harmful bacterial contamination.
Absolutely do not use plastic container lids without vents or plastic materials not suitable for microwave use, as they can easily lead to combustion, plastic burning due to high pressure.
If using glass food containers in the fridge and intending to microwave, you should let it sit at room temperature for 3 - 5 minutes before microwaving to avoid thermal shock causing container breakage.
Furthermore, it's advisable to minimize the use of plastic containers in the microwave, even though some types are indicated by manufacturers for microwave use. However, frequent use can lead to contamination and unpleasant odors.
