1. Common Techniques for Preserving Vegetables in the Refrigerator
Remove damaged parts of vegetables and fruits
Because when damaged, these parts will produce toxic ethylene gas, spreading bacteria and mold to other foods, causing harm to human health when consumed.
Before refrigerating, don't wash fruits and vegetables
Many people have the habit of washing vegetables before putting them in the fridge. However, this can make vegetables prone to damage and discoloration due to excessive moisture. If you want to wash vegetables, wait for them to dry and then place them in the refrigerator. Note: Minimize cutting vegetables into small pieces to preserve essential nutrients. For root vegetables like radishes, carrots, etc., trim the tops before refrigerating.
Classifying Vegetables
Each type of vegetable requires different storage conditions in terms of humidity and duration. Therefore, categorize your vegetables, place them in separate bags, and then store them in the fridge.
Use Nylon Bags for Food Wrapping
To keep vegetables fresh, maintain humidity between 80% and 95%. However, the typical humidity in the fridge is 65%. Therefore, place vegetables in nylon bags to prevent water vapor, keep higher humidity, and maintain the freshness of vegetables. Choose PP material for the bags to protect the health of your family members.
Appropriate Storage Temperature
Ensure that the temperature in the fridge is maintained between 1 and 4 degrees Celsius. If the fridge temperature exceeds 4 degrees Celsius, it creates an opportunity for bacteria to thrive. Temperatures below 1 degree Celsius will cause vegetables to freeze, spoil, and lose their nutritional value.
2. Tips for Preserving Fresh Vegetables Using a Paper Sheet
Preserving raw vegetables can be tricky compared to other foods. Even if you put vegetables in nylon bags and place them in the fridge, they may still get crushed, wilted, and slimy. Follow these preservation steps for keeping vegetables fresh for a week:
Step 1: Clean the vegetables with water to remove dirt, chemicals, and bacteria that can cause them to spoil quickly. Note: Wash the vegetables gently to avoid crushing.
Step 2: Use a paper towel to absorb excess water from the vegetables. This helps minimize the risk of vegetables getting soggy due to excessive water content.
Step 3: Take a dry paper towel and wrap the vegetables. The paper towel will absorb water to maintain moisture, preventing the vegetables from drying out and wilting.
Step 4: Place the vegetables in a ziplock bag and store it in the cool compartment of the fridge. You can use a plastic bag or container as an alternative to a ziplock bag. Ensure a tight seal to prevent external air from entering.
