To hasten the ripening process and achieve a uniform appearance, many suppliers resort to spraying chemicals on tomatoes with varying degrees of greenness. While it is common knowledge that consuming these chemically ripened tomatoes can be detrimental to one’s health, distinguishing them from naturally ripened ones is not an easy task.
How to Identify Naturally Ripened Tomatoes Without Chemicals
To differentiate between naturally ripened and chemically ripened tomatoes, pay attention to the following visual and tactile cues:
Observe the Color

Although chemically ripened tomatoes may look similar to regular tomatoes, there are some subtle color differences. Naturally ripened tomatoes, due to uneven sunlight exposure during growth, will have slight color variations on the same fruit. The area near the stem tends to be slightly greener, with the bottom ripening to a deeper red.
On the other hand, chemically ripened tomatoes often appear uniformly ripe all over. Even the area around the stem, which typically receives less sunlight, exhibits an unnaturally deep red color.
Examine the Bottom of the Tomato

This is a key indicator of whether a tomato has been treated with chemicals or not. Tomatoes that are naturally ripened tend to have a slightly concave shape at the top, with a round, plump body. This indicates a healthy growth environment.
On the other hand, tomatoes with protruding tops or oddly shaped fruits are likely the result of improper fertilization, poor growing conditions, or chemical ripening.
Inspect the Tomato’s Calyx

Tomatoes with dark green calyxes and fresh, vibrant branches attached to the stem are likely naturally ripened and fresh. Meanwhile, tomatoes with yellow or discolored calyxes are of lower quality and have likely been treated with chemicals or are older and have been stored for an extended period.
Check the Weight of the Tomato

Proper storage of tomatoes after purchase is essential to maintain their freshness and prolong their shelf life. It is best to keep tomatoes out of the refrigerator and store them at room temperature (around 25°C). They should be consumed within a week. If the tomatoes are already very ripe or the weather is particularly hot, consider storing them in the refrigerator to prevent spoilage.
