During Tet, every household usually prepares a variety of delicious dishes for the family to enjoy, resulting in a full refrigerator. During these holidays, careful food preservation is necessary to maintain the fresh and nutritional value of each ingredient.
Food Categorization
Before storing fruits, vegetables, and food in the refrigerator, it is important to organize them into separate categories. This not only helps prolong preservation time but also provides convenience when you need to retrieve them for cooking. Proper categorization also prevents flavor mixing between different types of food, ensuring that each maintains its distinct characteristics.
Fresh Food Preservation
When preserving raw food such as meat, fish, and seafood, it is crucial to keep them dry, as they often contain a lot of water and are prone to spoilage. To achieve this, rinse the food thoroughly and then use a vacuum sealer to remove the air from the packaging. This method prevents the food from changing color, losing nutrients, and helps maintain its natural flavor. When you need to use them, simply remove them from the freezer and thaw them in the microwave, a safe and hygienic method.
For vegetables, instead of washing them before storage, remove any damaged roots and leaves, then store them in leak-proof bags or place them separately in the bottom compartment of the refrigerator. This helps keep the vegetables fresh without having to come into contact with water, slowing down the decomposition process and extending shelf life.
Packaged Food Preservation
To ensure safety and extend the shelf life of packaged food, transfer them to airtight containers or cover them tightly with plastic wrap before storing in the refrigerator. This method prevents bacterial contamination and keeps the food from spoiling while also preventing the smell from spreading in the fridge.
When purchasing packaged food, keep them in their original packaging to protect the quality of the product. Only open the package when you are ready to use it and if you do not finish it, transfer the remaining portion to airtight containers and store them in the refrigerator. This not only helps preserve the food better but also maintains hygiene and avoids waste.
Preservation of Cooked Food
Food that has just been cooked should be completely cooled before storing in the refrigerator. Putting hot food directly into the fridge can cause food spoilage due to temperature differences and increase the risk of bacterial growth, affecting the quality and safety of the food. This can also raise the temperature inside the refrigerator, affecting other preserved food.
Use specialized food containers made of BPA-free and food-safe materials for storage. This not only helps maintain the freshness of the food but also ensures the health of you and your family. When you want to enjoy the preserved food again, properly heating it will restore the flavor and ensure the food is hot and delicious.
Preservation of Dry Food
For moisture-prone foods such as dried bamboo shoots, mushrooms, dried fish, nuts, and beans, proper storage is crucial. Keep them separated in zip bags or airtight containers and place them in a dry and cool place to avoid contact with high humidity. When using, be careful not to let them directly contact water or any source of moisture, as this can cause mold or fermentation, affecting the quality and safety of consumption.

How to Cut Down on Refrigerator Energy Consumption
Do you want to save money on your electricity bill? We’ve got solutions! Read on to learn our top tips that can help you reduce your power consumption when running your refrigerator.
– Create a food storage plan: Decide what food needs to be stored and for how long. Plan to use perishable items first and store longer-lasting items like canned goods for later.
– Keep your refrigerator organized: Group similar items together and use clear containers so you can easily see what you have. Keep frequently used items within easy reach.
– Utilize proper storage containers: Use airtight containers to prevent moisture loss and keep food fresh. Label containers with dates and contents for easy identification.
– Practice good hygiene: Wash your hands before handling food and ensure all utensils and surfaces are clean. Wrap or cover food before placing it in the fridge.
– Monitor temperature: Ensure your refrigerator is set to the correct temperature (below 5 degrees Celsius) to keep food safe.
– Separate ethylene-producing and ethylene-sensitive produce: Ethylene is a natural plant hormone that speeds up ripening. Keep ethylene-producing fruits (like apples, bananas, and tomatoes) away from ethylene-sensitive ones (like carrots, leafy greens, and broccoli).
– Store fruits and vegetables in the right conditions: Different produce has different optimal storage conditions. Some prefer the refrigerator, while others are best kept at room temperature. Use the crisper drawers in your fridge to control moisture and keep produce fresher longer.
– Wash and dry produce before storing: Remove any dirt or residue, then dry thoroughly. Moisture can promote spoilage, so ensure your produce is dry before storing it.
– Consider using produce savers: There are various produce saver products available, such as ethylene absorbers or special storage containers, that can help extend the life of your fruits and vegetables.
– Cool and store leftovers quickly: Don’t leave food at room temperature for more than two hours. Divide leftovers into small portions, place them in shallow containers, and cover them tightly before refrigerating.
– Reheat leftovers properly: Ensure leftovers are heated thoroughly to a temperature of 74 degrees Celsius or above to kill any harmful bacteria. Use a food thermometer to check the internal temperature.
– Use leftovers within a safe timeframe: Leftovers should be consumed within 3-4 days to ensure freshness and safety. Freeze leftovers if you won’t be using them within this timeframe.
– Label and date leftover containers: This helps you keep track of when the food was prepared and ensures you consume it within a safe period.
– Leftover vegetables: Chop and sauté leftover veggies to make a tasty frittata, stir-fry, or vegetable soup. You can also blend them into a smooth and nutritious soup.
– Extra rice: Use leftover rice to make fried rice, rice pudding, or stuff bell peppers or cabbage leaves for a delicious side dish.
– Meat scraps: Use leftover cooked meat in sandwiches, wraps, or salads. You can also add it to pasta sauces, casseroles, or stir-fries.
– Fruit leftovers: Blend overripe fruits into smoothies or use them to make fruit compote, which can be served with yogurt or ice cream. You can also bake them into muffins or quick breads.
– Defrost in the refrigerator: Plan ahead and thaw frozen food in the fridge overnight or for several hours. This slow and steady method helps prevent the growth of bacteria.
– Use the microwave defrost setting: If you’re short on time, use the defrost setting on your microwave. Ensure you follow the instructions and stop defrosting when the food is still icy, as the heat generated during defrosting can start cooking the food.
– Avoid defrosting at room temperature: Never leave frozen food to defrost at room temperature, as it can enter the temperature danger zone (5 degrees Celsius to 60 degrees Celsius), where bacteria multiply rapidly.
– Reheat thoroughly: When reheating food, ensure it reaches a safe internal temperature of 74 degrees Celsius or above. Use a food thermometer to check, especially when reheating dense foods like casseroles or meat dishes.
