Chemically ripened papayas using calcium carbide pose serious health risks. Under India’s FSS Act, this practice is banned, yet many vendors still use it. Uneven skin color, pale flesh, weak aroma, chalky residue, and odd texture are warning signs. Choosing trusted sellers, washing thoroughly, and reporting violations can help safeguard your health.
Many market papayas are artificially ripened using a dangerous chemical. That's where learning to spot a chemically ripened papaya and protect your health comes in.
A banned chemical called calcium carbide, also known as "masala," is used to ripen fruits like papaya, mango, and banana almost overnight. Not only is it a huge health risk, it's also quite cheap and fast-acting.
Under the Food Safety and Standards Authority of India (FSSAI) Act, calcium carbide is prohibited from being sold, because artificial ripening of fruits using acetylene gas (or carbide gas) is not allowed under law. In April 2026, FSSAI issued a nationwide directive to intensify inspections of fruit markets, storage facilities, wholesalers, and distributors.1
Most consumers can't tell a naturally ripened papaya from one artificially ripened. That's where knowledge comes in, acting as your primary defense.
Here's how you can identify a chemically ripened papaya.
A papaya that has ripened naturally will have a consistent yellow-orange color all over. A chemically ripened one often appears with patches of yellow, but still green in some areas. The yellow color will just be on the surface of the fruit.
Cut it open to check the color of the flesh. A naturally ripened papaya will have a deep red-orange flesh with fully formed black seeds, and will emit a sweet smell throughout the fruit.
A chemically ripened papaya might have light-colored, white, or uneven flesh, even if it looks yellow outside. Consumers have reported this as the most frequent clue.
Gently squeeze the fruit. A naturally ripe papaya will be evenly soft throughout the fruit. However, with carbide-ripened fruit, the outside layer will feel soft while the inside remains hard or rubbery.
An actual ripe papaya will give off a strong sweet, musky aroma near the stem. With a chemically ripened one, the scent might be faint, bland or even chemical.
Don't forget to rely on your sense of smell at the market; it's your best bet.
Calcium carbide is often applied directly onto fruit, so there may be a white or grey chalky residue left on the skin, especially around the stem end. FSSAI's current guidelines classify this residue as evidence of chemical ripening during inspections.
- Buy from vendors who are FSSAI compliant or from certified supermarkets
- Buy slightly under-ripe fruits and let them ripen on the counter in the next two-three days
- Make sure you wash your fruits thoroughly under running water even if you plan to throw away the peel.
- Immerse the fruit in clean water for about ten to fifteen minutes to rinse off any possible residues left after the application of chemicals.
- Report any suspicious vendor to the Food Safety Commissioner of your state
Before you buy the fruits take a moment to think... Look, feel, smell. A naturally ripe papaya is always worth the wait.
How can I distinguish a chemically ripened papaya from a naturally ripened one?
Chemically ripened papayas typically show uneven skin color with patches of green and yellow, pale or uneven flesh, a firm inside despite a soft exterior, a faint or chemical smell, and sometimes chalky powder residue on the skin. In contrast, naturally ripened papayas have consistent yellow-orange skin, deep red-orange flesh with black seeds, a strong sweet aroma, and an evenly soft texture.
What steps can consumers take to protect themselves when buying papayas?
Consumers should buy from FSSAI-compliant vendors or certified supermarkets, purchase slightly under-ripe fruits to ripen at home naturally, wash fruits thoroughly under running water, soak them for 10–15 minutes to remove residues, and report suspicious vendors to the Food Safety Commissioner.
Is buying from certified supermarkets a reliable way to avoid chemically ripened papayas?
Yes, certified supermarkets typically follow regulated cold-chain and ripening procedures compliant with FSSAI guidelines, reducing the risk of chemically ripened fruits. Purchasing from such sources increases consumer safety compared to local markets where calcium carbide use may be more prevalent.
How does the Food Safety and Standards Authority of India (FSSAI) address the issue of chemically ripened fruits?
FSSAI prohibits the sale of calcium carbide and chemically ripened fruits under the FSS Act. They conduct inspections, classify chalky residues as evidence of illegal ripening, and actively encourage consumers to report violations. Recent enforcement efforts since April 2026 aim to reduce health risks by promoting safer ripening practices.
Why is calcium carbide used for ripening papayas, and what are the risks?
Calcium carbide is used because it is cheap and fast-acting, ripening fruits almost overnight. However, it is banned under India's FSS Act due to health risks including potential chemical contamination. Consuming fruits ripened with calcium carbide can pose serious health hazards, such as respiratory and neurological problems.
