How to Identify Artificially Ripened Mangoes at Home

Check the skin colour

Artificially ripened mangoes often have a more uniform colour and may appear overly yellow or orange compared to naturally ripened ones. They can also look slightly shiny or unnaturally glossy.


Smell the mango

Naturally ripened mangoes usually have a strong, sweet, fruity aroma. In contrast, artificially ripened mangoes may have a faint, chemical-like, or unusual smell.

Check the firmness

Artificially ripened mangoes may feel softer or slightly mushy. This is because ripening chemicals can break down the fruit’s cell structure, affecting texture.

Look for external damage

Sometimes, chemically treated mangoes may show minor bruises, dark spots, or surface irregularities. Naturally ripened mangoes are generally more uniform and clean in appearance.

Conduct a taste test

Experts suggest that artificially ripened mangoes may taste bland or slightly off. A strange aftertaste or lack of natural sweetness can be a warning sign.

Soaking method

Place mangoes in a bucket of water. Naturally ripened mangoes are more likely to sink, while artificially ripened ones may float. (This is a commonly used traditional check, but not scientifically foolproof.)

Baking soda test

Soak mangoes in water mixed with baking soda for 15–20 minutes. After washing, if there is any noticeable change in color or surface appearance, it may indicate chemical treatment or polishing.

Matchstick test (use with caution)

Bring a lit matchstick near chemically treated mangoes may produce sparks or unusual reactions. This method is not scientifically reliable and can be risky. It should be avoided, especially without supervision or proper safety measures.

How to pick the right mangoes?

According to experts, one can follow the following rules while buying the right mangoes:.

1. Never buy too-perfect-looking mangoes.

2. Avoid too-shiny mangoes because they might be chemically treated.

3. Wash fruits thoroughly with running potable water before eating.

4. Avoid mangoes with black blotches on the skin, as they might be ripened by acetylene gas produced from calcium carbide.
