Mango season alert: How to check if your mangoes are naturally or chemically ripened

As mango season arrives, markets across India are filled with bright, attractive fruit. However, not all mangoes are ripened naturally. The Food Safety and Standards Authority of India (FSSAI) has repeatedly warned against the use of harmful chemicals like calcium carbide, which is often used to artificially ripen mangoes quickly. Knowing how to identify naturally ripened mangoes is important for your health.

Why Chemically Ripened Mangoes Are a Concern

Calcium carbide is sometimes used to speed up the ripening process. It releases acetylene gas, which mimics natural ripening but can leave harmful residues. According to food safety experts, consuming such fruits may cause headaches, dizziness, or even long-term health issues if exposure is frequent.

This is why it’s important to be cautious, especially during peak mango season when demand is high.

Look at the Colour Carefully

Naturally ripened mangoes usually have a mix of colours, green, yellow, and sometimes a slight reddish blush depending on the variety. They rarely look perfectly uniform.

On the other hand, chemically ripened mangoes often appear overly bright yellow or uniformly coloured. If all mangoes in a batch look exactly the same, it can be a warning sign.

Check the Smell of the Mango

One of the easiest ways to identify a naturally ripened mango is by its aroma. A ripe mango should have a sweet, fruity smell near the stem.

Chemically ripened mangoes may have little to no smell, or sometimes a slightly strange or chemical-like odour. If the fruit looks ripe but lacks fragrance, it’s worth being cautious.

Feel the Texture and Firmness

Naturally ripened mangoes feel slightly soft when gently pressed and have even softness throughout.

In contrast, chemically ripened mangoes may feel soft on the outside but hard inside. Some may also have patches that are too soft while other parts remain firm.

Look for Powdery Residue

Sometimes, mangoes ripened using calcium carbide may have a greyish or whitish powder on the surface. This residue can be a sign of chemical use.

Always wash mangoes thoroughly before eating, but if you notice unusual powder or marks, it’s better to avoid them.

Check the Inside of the Fruit

When you cut open a mango, a naturally ripened one will have a uniform yellow or orange colour inside.

Chemically ripened mangoes may show uneven ripening, with parts that are pale, hard, or less juicy.

Simple Home Tip: Water Test

Place the mango in a bowl of water. Naturally ripened mangoes usually sink, while artificially ripened ones may float due to internal changes.

While this is not a foolproof method, it can give you a quick idea.

Choose Safe and Healthy Mangoes

Whenever possible, buy mangoes from trusted sellers or opt for organic produce. Seasonal, locally sourced fruits are more likely to be naturally ripened.

With a little attention to detail, you can enjoy delicious mangoes without worrying about harmful chemicals.
