Mango Colour Why are mangoes yellow inside?

Aam pila colour — the golden-yellow shade — develops naturally as chlorophyll breaks down and beta-carotene forms during ripening. Alphonso mangoes from Ratnagiri and Devgad reach this peak colour from March to June, with Brix levels of 22–23°.

Why Aam Turns Pila: The Science of Mango Colour

A raw mango is green. A ripe one glows golden. That shift — the aam pila colour — is not cosmetic. It is chemistry.

When a mango ripens, its respiration rate rises sharply. The fruit produces ethylene, a natural ripening gas. Ethylene triggers a cascade of biological changes:

• Chlorophyll — the pigment that makes the skin and flesh green — breaks down and disappears.
• Carotenoids, chiefly beta-carotene and xanthophylls, accumulate in the flesh and skin.
• Anthocyanins, water-soluble pigments in the mango membrane, add orange, red, and yellow tones.
• Phytoene, a precursor compound, converts into orange-yellow carotenoids as ripening advances.

The result is the unmistakable golden-yellow flesh you see when you slice open a Ratnagiri Alphonso. That colour is beta-carotene made visible. It is also provitamin A — a nutritional marker, not just a visual one.

What Happens to Chlorophyll?

Chlorophyll degrades in the presence of ethylene and warmth. Enzymes called chlorophyllases break it apart. As green fades, the yellow carotenoids underneath — always present, always masked — become visible. This is why a mango does not manufacture yellow; it simply reveals it.

What Is Beta-Carotene?

Beta-carotene is a phytochemical and a carotenoid. It converts to vitamin A in the body. Alphonso mangoes carry some of the highest natural beta-carotene concentrations among Indian mango varieties. The deeper and more uniform the golden colour, the greater the carotenoid density — and the richer the nutrition and flavour.

Why Mangoes Are Yellow Inside

The skin tells half the story. The flesh tells the rest.

Inside a ripe Alphonso, the flesh is saffron-gold — deeper than most other varieties. Three compounds drive this colour:

1. Beta-carotene — the dominant pigment, responsible for the orange-yellow hue.
2. Carotenoids produced from phytoene — a complex chain reaction that intensifies the golden tone.
3. Anthocyanin — a water-soluble pigment in the mango membrane that contributes warmth and depth.

Soil composition, altitude, rainfall pattern, and temperature in Ratnagiri and Devgad all affect how much beta-carotene a fruit accumulates. Mangoes grown on the laterite-rich hillside orchards of villages like Velas and Harne in Ratnagiri consistently produce deeper colour than plains-grown fruit. This is why GI origin matters — it is not branding; it is biochemistry.

Mango Colour by Variety

Not every mango turns the same shade of pila. Colour is variety-specific.

• Alphonso (Hapus): Deep saffron-gold inside; skin progresses from green to yellow-gold with a faint pink blush at the shoulder. The most vibrant aam pila colour of any Indian variety.
• Kesar: Bright orange-yellow flesh; green-yellow skin that retains more green than Alphonso even when ripe.
• Pairi: Lighter yellow flesh; skin blushes red-orange near the apex.
• Totapuri: Pale yellow flesh; skin stays greenish-yellow even at full ripeness.
• Dasheri / Langra: Pale gold flesh; stays mostly green-skinned when ripe — no reliable aam pila colour on the outside.

For the classic golden aam pila colour — inside and outside — Alphonso from Ratnagiri or Devgad has no equal.

Delivery Across India

Orders placed before 12:00 noon dispatch the same day from our Ratnagiri packhouse. BlueDart air cargo handles all shipments.

• Mumbai, Pune, Goa: 1 day transit
• Delhi, Bengaluru, Hyderabad, Chennai: 1–2 days transit
• Kolkata, Ahmedabad, Jaipur: 2–3 days transit
• Northeast India: 3 days transit

Each box is packed in a ventilated corrugated carton with food-grade paper cushioning. No foam nets that trap heat. The mangoes arrive slightly firm and ripen naturally at room temperature over 1–2 days — arriving with their full aam pila colour intact.

Honest limit: We do not dispatch mangoes from July through February. The season ends. Fruit is not available outside March–June. Any site selling "Alphonso" in August is not selling Ratnagiri Alphonso.

Natural Ripening and Aam Pila Colour

The golden aam pila colour you see on a genuine Ratnagiri Alphonso is earned slowly. We use hay-bed ripening — fruit placed on dry grass in a cool, ventilated room and left to ripen on its own ethylene. No calcium carbide. No ethephon spray.

Carbide-ripened mangoes turn yellow on the outside within 24 hours. The skin patches unevenly. The flesh stays pale, sometimes white near the seed. The Brix reading is low — often 14–16°. The colour is yellow in name only.

Prashant Powle, who oversees sourcing across 48 villages in Ratnagiri and Devgad, grades each batch by hand. Fruit that does not show the correct colour development at picking is held back. Only mangoes with the characteristic saffron-gold flesh at 20° Brix or above leave the packhouse.

How to Tell Natural Ripening from Carbide Ripening by Colour

• Natural: Even golden-yellow skin; deep saffron flesh; pleasant floral aroma at the stem end.
• Carbide: Patchy yellow skin with green streaks; pale or chalky flesh; faint chemical or plastic smell near the skin.

How to Ripen Mangoes at Home

Leave the mangoes at room temperature — 24–28°C is ideal. Do not refrigerate unripe fruit. Cold stops ethylene production and freezes the colour at whatever stage it is at. A mango refrigerated while still green will not develop its full aam pila colour.

When Is the Colour Right to Eat?

The skin will be uniformly golden with no hard green patches. Press gently near the stem — the fruit gives slightly, like a ripe avocado. Smell the stem end. A ripe Alphonso smells of flowers and honey from 10 cm away. That is when the internal Brix peaks and the colour is deepest.

After Ripening

Once ripe, refrigerate and consume within 2–3 days. The colour holds. The flavour does not improve further once peak Brix is reached.
