What Happened
- The Food Safety and Standards Authority of India (FSSAI) issued a directive to Commissioners of Food Safety in all States and Union Territories, as well as FSSAI Regional Directors, to intensify inspections of fruit markets, mandis, storage facilities, wholesalers, and distributors ahead of the mango and summer fruit season.
- The order reiterated that calcium carbide — commonly known in the trade as "masala" — is strictly prohibited for artificially ripening fruits such as mangoes, bananas, and papayas, citing serious health risks including exposure to traces of arsenic and phosphorus released as acetylene gas.
- FSSAI flagged a specific violation: some food business operators (FBOs) are reportedly dipping fruits directly into chemical solutions, which goes beyond the use of prohibited gases and violates food safety standards.
- The authority reaffirmed that ethylene gas is the only legally permitted artificial ripening agent, subject to prescribed safety protocols.
- Non-compliance attracts action under the Food Safety and Standards Act, 2006, including fines, suspension of licences, and prosecution.
Static Topic Bridges
FSSAI — Mandate, Establishment, and Legal Basis
The Food Safety and Standards Authority of India (FSSAI) was established under the Food Safety and Standards Act (FSSA), 2006, which received Presidential assent on 23 August 2006 and came into force in phases from 2011. FSSAI replaced and consolidated eight earlier food-related laws, the most important of which was the Prevention of Food Adulteration Act (PFA), 1954. The authority is under the Ministry of Health and Family Welfare. Its core mandate is to lay down standards for food articles, specify systems for enforcement, and regulate, manufacture, distribution, sale, and import of food to ensure safe and wholesome food for human consumption.
- Established under: Food Safety and Standards Act, 2006
- Replaces: Prevention of Food Adulteration Act, 1954 (and seven other acts/orders)
- Administrative ministry: Ministry of Health and Family Welfare
- Headquarters: New Delhi
- Enforcement arm: State Food Safety Commissioners and Designated Officers at the district level
- International standard reference: CODEX Alimentarius standards (FAO/WHO joint food standards programme)
Connection to this news: FSSAI's authority to issue binding directions to State food safety commissioners flows directly from FSSA 2006; this order is an exercise of that supervisory power ahead of peak fruit-harvesting season.
Calcium Carbide — Chemistry and Health Hazard
Calcium carbide (CaC₂) reacts with moisture to produce acetylene gas (C₂H₂), which accelerates the ripening process in climacteric fruits (fruits that respond to ethylene). However, commercial-grade calcium carbide is impure and releases traces of arsenic hydride and phosphine — highly toxic compounds. Chronic exposure is associated with neurological damage; acute exposure causes dizziness, irritation of mucous membranes, vomiting, and in severe cases, pulmonary oedema. Because the gas contacts the fruit surface, residues can enter the food chain. Many countries have banned its use for food purposes, and Indian law (FSSAI Regulations) categorically prohibits it.
- Chemical reaction: CaC₂ + H₂O → C₂H₂ + Ca(OH)₂ (acetylene released)
- Impurities: arsenic hydride, phosphine — both toxic
- Health effects: dizziness, thirst, weakness, vomiting, skin ulcers, neurological damage
- Prohibited under: Food Safety and Standards (Prohibition and Restrictions on Sales) Regulations
- Trade name used by vendors: "masala"
Connection to this news: The FSSAI order targets use of calcium carbide specifically because its health risk profile is well-documented and enforcement failures during peak mango season create widespread public health exposure.
Ethylene Gas — The Permitted Alternative
Ethylene (C₂H₄) is a naturally occurring plant hormone (phytohormone) that triggers the ripening cascade in climacteric fruits by upregulating enzymes that soften cell walls, convert starch to sugar, and break down chlorophyll. Because it mimics the natural ripening signal, ethylene applied at controlled concentrations (typically 100 ppm) produces uniform ripening without leaving toxic residues. FSSAI permits its use under specific safety protocols, including controlled-atmosphere ripening chambers, as a legal alternative to calcium carbide.
- Classification: Natural phytohormone; also produced synthetically
- Permitted concentration: approximately 100 ppm in commercial ripening chambers
- Advantages: no toxic residues, uniform ripening, mimics natural process
- CODEX Alimentarius recognises ethylene as a processing aid for fruit ripening
- Requires investment in ripening chambers — a barrier for small traders, explaining continued calcium carbide use
Connection to this news: FSSAI's direction implicitly pushes FBOs toward ethylene-based ripening; the directive highlights that direct dipping of fruits in chemical solutions (another workaround) is also impermissible.
