Calcium Carbide or Ripening Masala Used in Fruits – Toxicity and Health Risks{Food Safety; Consumer Protection/Education/Awareness}

YAGAY andSUN

Introduction to Calcium Carbide and Ripening Masala

Calcium carbide (CaC₂) is a chemical compound that has been used in some parts of the world to artificially ripen fruits. The practice is particularly common in countries where natural ripening of fruits is slower or where fruits need to be ripened quickly for market purposes. Calcium carbide is often sold in the form of a powder or small pieces and is sometimes marketed as 'ripening masala.'

Calcium carbide reacts with moisture in the air to release acetylene gas (C₂H₂), which acts as a ripening agent. Acetylene is a gas that mimics ethylene, the natural plant hormone responsible for fruit ripening. However, while this process speeds up the ripening of fruits, the use of calcium carbide for this purpose raises significant health concerns.

Chemical Reaction: When calcium carbide is exposed to moisture, it reacts to release acetylene gas. The acetylene gas accelerates the ripening process by promoting the production of ethylene in the fruit, similar to the natural ripening process.Commonly Used Fruits: Calcium carbide is commonly used for ripening fruits such as bananas, mangoes, papayas, and other tropical fruits. These fruits are often exposed to the carbide in controlled environments, such as ripening chambers, to speed up their readiness for sale.

Toxicity of Calcium Carbide

The use of calcium carbide in fruit ripening raises several concerns due to its toxic nature. The primary dangers associated with calcium carbide are linked to the chemical itself and the contaminants often found in it.

Presence of Impurities:

Arsenic: One of the biggest concerns with calcium carbide is the impurities it contains, particularly arsenic. In many cases, commercially available calcium carbide is contaminated with high levels of arsenic, a known carcinogen. Arsenic exposure, even in small amounts, can be toxic and lead to serious health problems over time.Phosphorus: Calcium carbide may also contain phosphorus or other harmful chemicals that can pose additional risks to human health.

Health Risks Associated with Acetylene Gas:

Respiratory Irritation: The acetylene gas released during the ripening process can cause respiratory problems, particularly when inhaled in large quantities. Prolonged exposure to acetylene can irritate the airways and lead to coughing, shortness of breath, and even long-term lung damage.Skin and Eye Irritation: Direct contact with calcium carbide or acetylene gas can lead to skin irritation, burns, or even chemical reactions that can damage the skin. If the carbide powder comes in contact with the eyes, it can cause serious damage.

Chronic exposure to arsenic has been linked to cancers of the skin, lungs, liver, bladder, and kidneys.Neurological Effects: High levels of calcium carbide and its impurities may also have toxic effects on the nervous system, potentially leading to symptoms like dizziness, headaches, and even long-term neurological disorders with prolonged exposure.

Gastrointestinal and Systemic Toxicity:

• If calcium carbide or contaminated fruits are ingested, they may cause severe gastrointestinal issues, including nausea, vomiting, abdominal pain, and diarrhea. This can be particularly harmful to children or individuals with weakened immune systems.
Systemic poisoning due to arsenic or other contaminants can lead to fatigue, liver and kidney damage, and in severe cases, death.

Regulations and Guidelines Regarding Calcium Carbide Use

The use of calcium carbide in food, especially fruits, is prohibited or heavily regulated in many countries due to its potential health hazards.

India:

• In India, the Food Safety and Standards Authority of India (FSSAI) has explicitly banned the use of calcium carbide for ripening fruits. The authority has set clear guidelines for the ripening of fruits, including the use of controlled and safe methods like ethylene gas, which is a naturally occurring ripening agent, and the use of controlled ripening chambers.
• Despite these regulations, calcium carbide is still widely used illegally in many parts of India, particularly in street markets or by unscrupulous vendors looking to speed up fruit ripening.

European Union and United States:

• In both the EU and the US, the use of calcium carbide for ripening fruits is banned. Authorities such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have strict regulations against the use of non-natural ripening agents due to health concerns.

Other Countries:

• Many other countries, including those in Asia and Africa, where calcium carbide is sometimes still used for ripening fruits, have also set regulations that limit or prohibit its use, though enforcement may vary.

Alternatives to Calcium Carbide for Fruit Ripening

There are safer, natural, and approved methods available for ripening fruits without the dangers associated with calcium carbide:

Ethylene Gas:

Ethylene gas is the natural plant hormone responsible for fruit ripening. Ethylene generators are widely used in controlled environments like ripening chambers for fruits such as bananas, tomatoes, and mangoes.
• This method is safer and free from toxic contaminants, making it the preferred choice in regulated markets.

Controlled Ripening Chambers:

• Controlled ripening chambers use a combination of temperature, humidity, and ethylene gas to ripen fruits in a safe and efficient manner. This method is widely used by large-scale fruit producers to ensure that fruits ripen uniformly and without harmful chemicals.

Natural Ripening Methods:

• In some cases, fruits can be allowed to ripen naturally without the need for artificial interventions. For instance, bananas and mangoes can ripen at room temperature over a few days.
• Other traditional methods, like using clay pots or natural ripening environments, can also be safer alternatives to chemical-based ripening.

Food Safety Tips for Consumers

Buy from Trusted Sources:

• Purchase fruits from reputable markets or vendors who comply with food safety regulations. Avoid buying fruits from street vendors or markets that may use unsafe ripening methods like calcium carbide.

Inspect Fruits for Signs of Artificial Ripening:

• Fruits ripened using calcium carbide may have an unnatural color, a waxy texture, or may be unusually too soft or overripe. Be cautious of fruits that ripen too quickly or have an odd taste or smell.

Wash and Peel Fruits:

• While washing and peeling may not eliminate the harmful effects of calcium carbide, it can help reduce exposure to surface contaminants. Always wash fruits thoroughly before consumption.

Advocate for Safer Practices:

Conclusion

The use of calcium carbide or ripening masala for accelerating the ripening of fruits poses significant health risks due to the toxic impurities such as arsenic and phosphorus. While this method of ripening may be cost-effective and quick, it is dangerous for consumers and poses serious health hazards, including cancer, gastrointestinal problems, and neurological damage. Regulatory bodies around the world have banned or restricted its use in food products, but it is still sometimes used illegally. Consumers should be cautious when buying fruits and ensure they are sourced from reputable suppliers using safer, approved ripening methods like ethylene gas or controlled ripening chambers.
