8 simple tips to prolong the life of food

1. Onions

We can keep onions fresh for up to 8 months if we use the right storage methods. Place onions in tights and tie a knot between each one; or put onions in paper bags. Onions should be stored in a dry place with a cool bag. Absolutely avoid putting onions in plastic bags because this type of bag will make onions moldy and sprout quickly. With peeled and cut onions, should be covered with cling film and stored in the refrigerator.

2. Berries

With berries, it is recommended to wash them with a dilute vinegar solution before storing. Make this solution to a concentration of one part vinegar (can be white vinegar or apple cider vinegar) and ten parts water. Then, gently dip these fruits into the mixed solution, take them out to drain and put them in the refrigerator. Because the concentration of vinegar is very low, there will be no taste on the fruit. With this method, you can store raspberries for a week, strawberries for two weeks without mold and rot.

3. Avocado

One of the most effective ways to preserve this fruit is to use cooking oil. Spray a little oil on the cut avocado before putting it in the fridge. It will help the avocado stay fresh and keep its green color. In addition, note that it is advisable to keep the seeds of the cut avocado to preserve the avocado flesh more effectively.

4. Lettuce

Preparing lettuce for storage is the same as preparing it for eating. First, cut the vegetables, wash and pay attention not to crush the vegetables, then shake off the water. If you have a vegetable peeler, even better. This step is very important because moisture is the enemy of fresh lettuce. Then, place the lettuce in a large bowl and cover your mouth with a piece of paper towel or two. This helps prevent moisture from seeping into the vegetables while in the refrigerator. Finally, cover the entire bowl with cling film and place in the refrigerator. With this method, the lettuce can stay fresh for a week.

5. Spices

You can preserve herbs by placing them in ice cube trays and drizzling them with olive oil before placing them in the freezer. Vegetables will soak up the olive oil while being refrigerated. In addition, olive oil and “vegetable ice cubes” will also make cooking easier. This preservation method works very well with rosemary, sage, thyme, and oregano leaves. Also, with fennel, basil, and mint, it's best to use fresh.

6. Bananas

Banana is a very difficult fruit to preserve. To slow down the darkening of bananas, cover the bananas with plastic wrap. This method will keep bananas fresh for about 3 to 5 days longer than usual. Also, note that this fruit produces more ethylene gas than other fruits. Therefore, you need to store them in a separate place to avoid damaging other fruits.

7. Bread

For unused bread, the best way to store it is to keep it in the freezer. Usually we keep bread in the refrigerator, but this is not the ideal method in this case. The reason is that bread stored in the refrigerator will dry faster and spoil faster than at room temperature. If stored in the freezer, we can keep the delicious unsliced ​​bread for up to 3 months.

8. Tomatoes

Absolutely do not store tomatoes in plastic bags. Tomatoes produce ethylene gas and plastic bags prevent this gas from escaping, making tomatoes ripen faster. Unripe tomatoes should be kept at the bottom, put in a paper bag or put in a cardboard box but do not let the tomatoes overlap. Then, leave the tomatoes in a cool, dry place until they turn red. Medium ripe tomatoes should be stored at normal temperature, away from sunlight, tomato stalks facing up and not stacked. Overripe tomatoes should be stored in the refrigerator. However, note that tomatoes must be removed from the refrigerator for a while before using.
