Why Are Tomato Skins Tough They Could Be Useful

Tomatoes are an amazing fruit that has been used for thousands of years. They have first cultivated in Peru around 5000 BC. Tomatoes are a member of the nightshade family along with potatoes and eggplants.

The tomato is one of the most popular fruits grown worldwide, especially in Europe where it’s known as “the king of vegetables”. It can be eaten raw or cooked but its main use is to make sauces, soups, stews, salads, juices, jams, ketchup, etc… The skin on tomatoes contains lycopene which helps prevent cancer. This makes them very healthy!

Tomato skins are often discarded after being picked because they are too soft. However, there are many uses for these skins other than making tomato sauce.

You might think that tomatoes are only used for their flesh, but they also contain a lot of nutrients. In fact, the skins contain more vitamin C than the whole fruit.

Why is the Skin on tomatoes tough?

There are two main reasons why the skin of tomatoes is so tough: they were bred to be that way, or they were exposed to harsh environmental elements such as excessive and dry heat, insufficient watering, and direct sunshine.

All of these variables lead to a leathery-skinned tomato, which is primarily caused by a lack of water and humidity within the tomato. Tomatoes are a delicate plant.

Environmental conditions really matter

When we talk about growing tomatoes, we usually refer to how much sunlight they get during the day. But what if I told you that the amount of light doesn’t even come close to determining whether your plants will grow well?

In reality, the environment plays a huge role when it comes to growing tomatoes successfully. If you don’t give them enough moisture, then they won’t produce any fruit at all. And if you overdo it, then you may end up with a bunch of wilted leaves instead of ripe red ones.

The perfect temperature for ripening tomato is between 65°F and 75°F. Too hot and they will not develop properly; too cold and they will rot before reaching maturity.

Tough skins can be very useful during transport

It turns out that the tough skins of tomatoes are actually quite useful. You see, they protect the fruit from breaking apart while transporting it. When you buy a fresh tomato off the shelf, it should feel firm and heavy. That means that the skin was still attached to the stem.

However, once you cut open the package, the tough skin becomes loose and floppy. So, this is another reason why you shouldn’t throw away those extra pieces of tomato skin. They could help preserve food longer

Another interesting thing about tomato skins is that they act as natural preservatives. For example, if you put some sliced tomatoes into a jar filled with olive oil, then place the lid back onto the container, the slices will stay intact for several weeks.

This is due to the presence of lactic acid bacteria found inside the tomato skin. LAB are naturally present in our bodies and they play a key role in maintaining good health. They have been shown to reduce cholesterol levels, fight infections, improve digestion, boost immunity, and promote weight loss.

So, next time you find yourself throwing away an entire piece of tomato skin, consider using it to preserve foods like olives, pickles, sauerkraut, and cheese.

Try heirloom tomatoes for thin skins

Tomato varieties tend to vary greatly depending on where they originated. Some are extremely juicy, others are drier and less flavorful. However, one common trait among most types of tomatoes is that they do not have thick skins. This makes them ideal candidates for slicing because there isn’t anything holding them together.

Heirlooms are often referred to as “old-fashioned” because they are typically smaller and rounder compared to modern hybrids. These fruits also tend to have thinner skins than their hybrid counterparts.

If you want to try growing heirloom tomatoes, make sure you choose varieties that were grown organically or sustainably. The best way to ensure that your tomatoes are free from pesticides and other harmful chemicals is to purchase organic seeds. You might also want to look for seed companies that offer heirloom tomato seeds specifically designed for home gardeners.

How can tomato skin be useful?

When we eat tomatoes, we usually discard the seeds and the peel. But why do we throw away this part when it could help us so much?

Thick Tomato Skins: What Causes Tough Tomato Skin | Tips for growing  tomatoes, Growing tomatoes, Tomato problems

In order to understand how useful the tomato skin is, let’s start by looking at what happens during the ripening process:

As soon as the plant starts producing flowers, the ovaries begin to swell up. When the flower petals fall off, the ovary begins to produce pollen grains. These will then travel through the air until they land on another flower. If the pollen lands on a female flower, it fertilizes her eggs. Then, the seed grows inside the ovary. After several weeks, the embryo develops into a tiny green ball called a zygote. At this point, the cell walls break down and the cells become loose. Once all the water evaporates from the cells, the zygotes turn brownish-yellow. Finally, the zygotic embryos develop into mature seeds.

During this time, the tomato undergoes two important changes:

First, the color turns red. Second, the texture becomes softer.

This means that if you cut open a ripe tomato, you should see some yellow juice coming out. And if you squeeze the pulp between your fingers, it should feel like jelly. These characteristics allow us to distinguish between unripe and ripe tomatoes. Unripe tomatoes don’t look anything like ripe ones. Their colors aren’t bright enough and they still retain a hard consistency. On top of that, they smell bad.

So, if you buy a bunch of tomatoes without knowing whether they’re ready yet, you won’t know if they’ll taste good or not.

Are tomato skins easy to digest ?

The answer depends on which type of tomato you use.

Tomatoes with thicker skins contain more fiber. In fact, these fruits are considered healthy since they provide many nutrients such as vitamin C, potassium, magnesium, iron, folate, niacin, riboflavin, thiamine, phosphorus, zinc, copper, manganese, calcium, sodium, and protein. On the other hand, thin-skinned tomatoes lack nutrition. For example, they only contain about half the amount of vitamins found in regular tomatoes. Furthermore, they may even cause digestive problems due to their high acidity level.


It seems obvious now but I hope my article has helped you realize just how beneficial the tomato skin is. It provides essential minerals and nutrients while being very low in calories. So next time you go shopping, remember to pick up those extra tomatoes!
