If not properly preserved, fresh vegetables bought only last 1-2 days. Even if stored in the refrigerator, vegetables only last a few days before they spoil. In fact, keeping vegetables fresh for a long time is not difficult, it’s just important that you do it properly.
Before proceeding with preservation, there are some important points you need to note:
– Humidity: create a suitable environment with moderate humidity to keep vegetables longer.
– Temperature: too high temperature will cause vegetables to wilt, too low temperature can make vegetables rotten or wilted leaves.
During the preservation process, pay attention to:
– Choose fresh and green vegetables without any wilted parts. Remove any damaged leaves. Wash the vegetables thoroughly and let them drain before preservation.
– Store the vegetables in a cool and ventilated place, away from direct sunlight.
– Use plastic bags, paper, or other materials to protect the vegetables.
Steps to preserve fresh vegetables with paper
Many people use newspapers to wrap and cover vegetables. However, experts suggest that these papers contain high amounts of lead and other harmful substances that are not good for health.
Therefore, experts recommend using edible paper as a replacement. This type of paper is highly safe and will absorb moisture on the vegetable leaves, maintaining an ideal moisture environment. In addition, this type of paper is lightweight, which can prevent the vegetables from being crushed.
The steps to preserve fresh vegetables using paper are as follows:
– Step 1: After picking the vegetables, wash them thoroughly and use a paper towel to remove all water from the surface of the vegetables.
– Step 2: Place a dry paper towel at the bottom of a plastic container.
– Step 3: Put the dried vegetables from step 1 into the container. Note that you should not apply pressure to avoid crushing or damaging the vegetables.
– Step 4: Add another layer of dry paper towel on top of the vegetables and close the container tightly.
Preservation instructions for each type of fresh vegetable
Each type of fresh vegetable may require different preservation methods. Therefore, when preserving, you also need to pay attention to each type’s specific requirements.
– Leafy vegetables: Wrap them with edible paper, then put them in a Ziploc bag and store them in the refrigerated compartment of the refrigerator.
– Root vegetables: Just keep them in a dry and ventilated place.
– Fruits: Store them in the refrigerated compartment of the refrigerator.
– Mushrooms: Wash them thoroughly, remove excess water, put them in a paper bag, and store them in the refrigerated compartment of the refrigerator.
– Herbs: Wash them thoroughly, place them in cool and ventilated areas or in the refrigerator. For herbs like onions and leeks, you can leave them with the roots and place them in a glass or bowl of water, then cover them with a sealed bag. This method helps keep the herbs fresh for up to a week.
