In some households, daily market trips are the norm for fresh groceries. However, others prefer a weekly supermarket visit, storing food for gradual consumption. Hence, they need effective ways to keep vegetables fresh in the fridge for several days. Explore Mytour's guide on preserving vegetables in the fridge in the following article.

Common Issues in Storing Vegetables in the Fridge

Preserving vegetables is a method to prevent them from spoiling and becoming damp, even when stored for several days. Typically, vegetables tend to ripen or become infected under regular conditions because the nutrient content in vegetables decreases.

Ripening Phenomenon

After harvesting, a biochemical process converting sugars and oxygen into carbon dioxide, heat, and water occurs in various types of vegetables and fruits. As they undergo respiration with high intensity, leading to a gradual ripening state, it's essential to learn ways to store vegetables in the fridge to slow down the wilting process.

Phenomenon of Fungal and Bacterial Contamination

Bacteria and fungi are factors that make vegetables and fruits prone to spoilage and rot if left unused for too long. Even if you manage to slow down the ripening process, the risk of vegetables and fruits being contaminated by bacteria or fungi remains high. Therefore, it's crucial to understand the growth and development process of fungi and molds by monitoring any abnormal appearances on the surface of vegetables and observing influencing factors such as environmental temperature, hygiene, and storage conditions.

Factors Influencing the Preservation Process

Temperature

The speed of biochemical processes in vegetables and fruits is influenced by temperature. Hence, temperature is the most crucial factor to consider. Lower temperatures slow down the respiration reactions, inhibiting the growth of most microorganisms.

Humidity

Vegetables and fruits wrinkle due to water loss, primarily caused by low environmental humidity. Disruptions in metabolic activities lead to reduced resistance, making them susceptible to bacterial attacks. On the contrary, high humidity minimizes respiration and limits water loss, but it creates favorable conditions for microbial growth. To mitigate high humidity, you can use food wrap to seal the vegetables and fruits tightly.

Other factors in the air

• Oxygen (O2) or Carbon Dioxide (CO2) levels influence the shelf life of food.
• Ethylene (C2H4) is a colorless, tasteless gas, toxic in nature, often present in ripe fruits during the food ripening stage.

How to store vegetables in the refrigerator's cool compartment

Storing vegetables in the refrigerator is a method to keep the freshness of food and balance the factors. So, how to effectively store vegetables in the refrigerator's cool compartment?

1. Remove damaged or crushed parts before placing them in the refrigerator

Ethylene gas is often produced by damaged vegetables; they can spread decay to the intact parts. Therefore, remove all damaged portions to minimize this situation.

2. Use paper for vegetable storage

Paper helps absorb excess water to prevent vegetables from getting soggy due to residual water before placing them in the cool compartment. Thus, you can use paper to store vegetables in the refrigerator to address the issue of waterlogging and rotting.

3. Avoid washing vegetables before placing them in the refrigerator

High humidity and wet vegetables after washing create favorable conditions for mold and bacteria growth. If your family has the habit of washing vegetables before putting them in the refrigerator, make sure to let them air-dry thoroughly.

4. Classify vegetables and fruits during storage

Fruits usually produce ethylene gas, which can lead to yellowing if absorbed by vegetables. Therefore, prepare ziplock bags or containers to separate vegetables and fruits during storage.

5. Avoid cutting vegetables into small pieces before refrigerating

Nutrient content in vegetables will be somewhat lost when cut into small pieces. This also creates opportunities for bacteria to exist and thrive.

6. Use specialized plastic bags and containers for storing vegetables

For better vegetable storage in the refrigerator, use specialized plastic bags and containers to separate different types of vegetables and fruits. When using these tools, food will be ensured for hygiene. Moreover, you can use paper towels to absorb moisture to prevent spoilage. You can explore convenient Tupperware food storage containers for added safety.

7. Pay attention to storage time

The storage time depends on the temperature in the refrigerator and different types of vegetables have varying shelf lives. Generally, the average storage time for vegetables ranges from 3 to 7 days.

8. Regularly clean and sanitize the refrigerator

Before storing food, it's essential to clean the refrigerator regularly to ensure cleanliness, prevent the growth of bacteria, and minimize unpleasant odors in the refrigerator.

How to store vegetables in the freezer compartment 

To store vegetables effectively in the freezer compartment, follow these steps:

• Choose vegetables that are not crushed to avoid the bacterial growth from the crushed parts causing spoilage.
• Cleanse the vegetables you want to store in the freezer. Washing vegetables helps eliminate microorganisms, yeast, and bacteria present on the food. Additionally, thoroughly cleaned vegetables reduce the chances of sogginess and spoilage.

Some tips for storing vegetables in the refrigerator 

Storing vegetables in the refrigerator may not yield good results and can even have adverse effects if you overlook the following tips:

• Temperature inside the refrigerator: ideally between 1°C and 4°C. At this temperature, the low bacterial growth rate helps extend the shelf life of vegetables.
• Do not leave the freezer compartment empty: when the freezer compartment is empty, the energy used to cool the vegetables will be reduced. If you have no food to put in the freezer, replace it with ice packs. In case of a power outage, the melted ice packs will provide the necessary temperature to keep the food cool in the lower compartments.
• Storage time for vegetables in the refrigerator: with proper storage, vegetables can be preserved for a maximum of 8 to 10 months. Additionally, some types of vegetables can be stored for up to 1 year.

Types of vegetables to store – not to store in the refrigerator 

Not all types of vegetables are suitable for refrigerator storage; they are categorized into distinct groups:

• Onions
• Garlic
• Potatoes
• Butternut Squash
• Sweet Potatoes

Group 2: Types of fruits and vegetables that should go into the refrigerator only after ripening

In cold temperatures, there are certain types of fruits and vegetables that are still green and should not be stored in the refrigerator. Instead, you should let them ripen before storing:

• Avocado
• Tomato
• Pear
• Peach
• Banana
• Plum
• Mango
• Papaya

Group 3: Types of fruits and vegetables to be refrigerated immediately after purchase

Frequently Asked Questions about Storing Vegetables in the Refrigerator 

Storing vegetables in the refrigerator can be effective when done correctly, but users still have some questions regarding this issue, such as:

How to store water spinach and lettuce in the refrigerator to keep them fresh?

Firstly, you need to clean the vegetables to remove any soil or residue when freshly purchased. Then, place the vegetables in a bowl or plate (depending on the quantity you want to store). Next, use paper towels to place on the surface to absorb water, keeping the vegetables dry while retaining moisture within. Finally, use plastic wrap to tightly cover the vegetables and place them in the refrigerator.

Why do fresh fruits and vegetables last longer in the refrigerator?

The reason fruits and vegetables stay fresh when stored in the refrigerator is because the temperature inside the fridge reduces the intensity of chemical and biological changes, thereby extending the shelf life of the food.

What is the storage temperature for vegetables in the refrigerator?

Typically, the recommended storage temperature in the refrigerator should range between 1°C and 4°C. If it exceeds 4°C, bacteria will have the opportunity to thrive and grow.

How to preserve green vegetables without a refrigerator?

When lacking a refrigerator, you can preserve vegetables using household items such as sealed bags (ziplock bags), water preservation, and sharp toothpicks.
