If the tomato has black or green mold on it with a film of wax then it definitely is bad news. Fresh tomatoes have a smooth texture, molds can be dangerous for health if they are consumed leading to food poisoning. 

Wrinkles on tomatoes doesn’t always mean that it is bad, instead it is a sign that the tomato is dehydrated. You can cut the tomato to see whether there are molds inside the tomato or not. 

Liquid oozing from the tomato

When tomatoes go bad, their outer skin becomes very mushy which means that they lose their original weight. The mushy surface sometimes leads to oil like liquid oozing out of the tomato.

Shelf life of canned tomatoes

Canned tomatoes can last for an entire year if they are unopened. The preservatives inside prevent the tomatoes from going bad or any bacteria from coming inside. Once the can is open, try to use it within a week when the tomatoes will be fresh. Keep it refrigerated at all times.

What happens when tomatoes overripe

Freezing overripe tomatoes will let you use them a week later too. The frozen tomatoes will have to be thawed and defrosted. Don’t use them in salads because the taste might have changed, that’s why it is better to cook them. 

Remove the stem of the tomato and put them in a plastic bag before you toss them in the freezer.

STore the cut tomatoes by placing them in an air-tight container and placing them in the refrigerator. You don’t want to put them in the coldest part of the refrigerator, just the section that is cold enough to keep the tomatoes fresh and dry. 

What causes the tomatoes to go bad?

There are some factors that increase the aging process of tomatoes, avoid the following habits when you store tomatoes. 

  • Putting ripe tomatoes in a plastic bag will make their skin sloppy and also cause molds to grow. This is because of the moisture that gets trapped inside the bag. This is why ripe tomatoes should always be stored in a dry and cool place away from sunlight. 
  • Although refrigeration is a good way to protect tomatoes from overripening, it will change the taste of tomatoes. This is why a cool pantry is preferred over refrigeration.
  • Don’t store tomatoes in a pile, this will bruise the skin because of the pressure on the delicate skin. If there is a crack, it gives way for bacteria to start growing in that place.
