Any remaining food after meals should be properly preserved using the following methods:

– Plastic food containers.

– Food wrapping film.

– Foil or foil-lined food containers.

– Antibacterial food preservation bags.

– Vacuum seal bags.

– Jars or containers with airtight lids.

Each method of food preservation will have its own advantages and disadvantages, and is suitable for different types of food. The following guidelines will help you choose the best method to preserve leftover food after meals.

1. Plastic food containers
 
 

Storing and preserving food in plastic containers is the most common choice. In addition to large containers used to store large quantities of dry food, you can also choose containers that are the right size for the amount of leftover food. Plastic containers usually have a tight lid, making them airtight and suitable for preserving grains, rice, noodles, or dried meats with little moisture.

One of the biggest advantages of plastic containers is that they can be reused. After each use, simply clean them thoroughly, remove any odors, and dry them for the next use. The biggest disadvantage of plastic containers, especially cheap ones, is that they are easily stained and retain odors. Therefore, you should choose containers that are the same color as the food being preserved to avoid discoloration. For example, choose containers in orange color to preserve dishes with curry or chili sauce.

2. Food wrapping film

Food wrapping film is considered a convenient and easy-to-use method of food preservation that keeps the food tightly sealed. One of the advantages of food wrapping film is that it can be used in the microwave when you need to heat up liquids or soups without worrying about food splattering or spilling out.

3. Foil or foil-lined food containers
 

This is also a relatively popular method of food preservation. Many people find that using foil is more convenient than using plastic wrap. However, foil cannot be used in the microwave when you want to heat or cook food in this type of oven. Foil makes it easier to wrap food. It is quite durable and sturdy, making it suitable for wrapping food before putting it in the refrigerator. In addition, foil also prevents food from freezing.

Food containers lined with foil are often used by restaurants to preserve food before serving. These containers can be reused. However, they are also not suitable for use in the microwave and are difficult to clean. You need to be very careful when cleaning these foil-lined containers to avoid scratching the foil lining inside. In addition, the risk of food poisoning from preserved leftovers in these containers is higher compared to other preservation methods.

4. Antibacterial food preservation bags
 
 
These bags have the function of keeping food cold in the freezer and have antibacterial properties to ensure the safety of the preserved food. They are a relatively new method of food preservation and are considered environmentally friendly. These bags are suitable for short-term preservation of frozen food. If you want to preserve leftover food for a longer period of time, you should choose a different method as the durability and strength of these bags are not high.
 
5. Vacuum seal bags
 
 

Some vacuum seal bags can be used multiple times, but most are single-use. This preservation method is the best choice for dry and non-liquid food. Vacuum seal bags are also used to preserve fresh food in the refrigerator. As the air is sucked out, vacuum seal bags help keep the food fresher for longer.

6. Glass jars or containers
 
 
Glass is a material that can keep dry food fresh for a long time. Air cannot penetrate through glass, similar to plastic containers, so you do not need to use moisture absorbers to prevent food from becoming damp or moldy. The biggest advantage of glass jars and containers is that they are very durable and can be used multiple times.
