Food Adulteration: Types, Causes, & Detection

Food adulteration is an issue that is sparking growing concern due to its direct effect on human health and well-being across the globe. I think it is very important for us as dieticians and nutritionists at Qua Nutrition to get informed about this issue so that we can make our own decisions on what we eat. The article shall delve into the types, causes, and detection of food adulteration together with useful rectifications to guard ourselves.

What is Food Adulteration?

Adulteration means adding harmful or substandard substances to foodstuffs with the intent to increase volume or improve appearance, sacrificing the quality and safety of food. Adulteration can take place anytime during the production of food, from field collection to packaging.

Food adulteration is defined by the World Health Organization (WHO) as the intentional addition of any substances that make food inferior or the introduction of harmful materials that may pose health concerns.

Accordingly, one of Qua’s senior dieticians states, “This is a very serious thing about adulteration, loss of quality of food with negative health impacts.”

Causes of Food Adulteration

Food adulteration is widely recognized as being caused due to many factors, including: 

1. Economic Benefit: Producers would adulterate foods to either cut down costs or make a simple profit. For example, mixing poor-quality grains with high-quality ones lessens production costs while enhancing the market supply. 
2. No Regulation: The lack of supervision and enforcement gives opportunistic manufacturers loopholes that allow certain unethical acts to be performed. 
3. Consumer Demand: The great public demand for products that are cheaper and visually appealing induces their producers to consider using artificial enhancements.
4. Negligence and Ignorance: Sometimes, the introduction of adulterants may exactly be a result of ignorance regarding food hygienic practices or due to bad personal hygiene by farmers, manufacturers, or suppliers.

Methods of Food Adulteration

Food adulteration can take many forms, each with different consequences.

1. Intentional adulteration: the addition of water, starch, or chemicals to increase weight or volume. 

• For example, one might dilute the water in milk or add artificial, synthetic colouring agents to turmeric for a better appearance.

1. Incidental adulteration: This takes place during the harvesting, storing, or transporting of substances due to uncleanliness or environmental factors.

• For instance, there are pesticide residues in vegetables or grains that are stored under damp conditions and develop fungal toxins.

1. Metallic contamination: It is the introduction of chemicals resulting from either packaging materials or equipment or due to environmental pollution

• Examples of these are lead, arsenic, and mercury. They are quite detrimental as they accumulate in the body with time.

1. Packaging adulteration: It means using cheap or reactive packing materials that contaminate the food with hazardous substances, like when toxic chemicals from plastic packaging are absorbed into acidic or even oily foods.
2. Substitution adulteration: It means using inferior substitutes for capital-intensive ingredients.

• For instance, tamarind seed powder or chicory is occasionally used in place of pure coffee powder.

Common Adulterated Foods and Their Adulterants

Many everyday foods are prone to adulteration. Here are some examples:

Each of these adulterants not only degrades the quality of food but also introduces harmful effects that can be life-threatening.

Health Hazards of Food Adulteration

The consumption of adulterated food can lead to both short-term and long-term health problems.

Acute Effects

1. Food Poisoning: Diarrhea, Vomiting, and dehydration.
2. Nausea and Abdominal Pain: Usually due to adulterants, such as detergents or synthetic chemicals.

Chronic Effects

1. Neurological Disorders: Adulterants such as lead and mercury can cause damage to the nervous system that will sometimes show symptoms of tremors, memory loss, or developmental issues.
2. Organ Damage: Long-term exposure to poisonous chemicals can result in kidney, liver, and heart disorders.
3. Cancer: Carcinogens are found in synthetic dyes and chemicals used in food adulteration.

“The effects of food adulteration can be very damaging for children and the elderly.”  – Qua Nutrition experts.

How to Detect Adulterated Foods at Home

Though the laboratory test method is the best method of testing, some simple tests with less credibility may still detect certain kinds of foods that enter the market in adulterated form.

1. Milk: A drop of milk mixed in water. The watered pure milk forms a thin layer; adulterated milk dissolves in water quickly.
2. Honey: A drop of honey on blotting paper. Honey will not spread, while adulterated honey will leave a ring of water.
3. Turmeric Powder: By adding water into a glass. Adulterated turmeric powder shows a yellow layer at the bottom due to coloring matter.
4. Salt: Dissolve in water. If salt is adulterated with chalk powder, then it will settle at the bottom.
5. Vegetables: Soak in water for about 15 minutes. Colored vegetables will release their dye into the water.
6. Sugar: Dissolve in water. Washing soda or chalk powder settles at the bottom.

Tips to Avoid Adulterated Food

Protecting oneself from tampered food requires the application of a few straightforward habits:

1. Buy from Trusted Sources: Get food from reputable brands or certified vendors.
2. Check the Labels: Look for quality certificates such as FSSAI, ISO, AGMARK, etc.
3. Avoid Bright Colors: Foods with dull colors are less likely to be dyed with harmful colors.
4. Wash Thoroughly: Wash fruits and vegetables under running water to take care of the surface contaminants. 
5. Cook Properly: Heating can neutralize some harmful microorganisms and chemicals.
6. Use Filtered Water: For washing or cooking, to avoid contamination.

“Prevention starts with awareness; always inspect food before buying,” – Qua dietician.

Steps to Be Taken to Stop Food Adulteration

To combat food adulteration, steps can be taken at various levels: 

1. Stricter Regulation: Governments need to put strict food regulations in place for quality control at every stage of production.
2. Regular Inspection: Heightened inspection of food production and transportation for prompt detection and determent of dishonest practices.
3. Consumer Awareness: Educate the public about how to identify and avoid rejected food through campaigns and workshops.
4. Implementation of Technology: Utilization of sophisticated methods like chromatography and spectroscopy for food testing and quality assurance.
5. Punitive Measures: The offenders shall be meted out with heavy penalties to deter dishonest practices. There should be heavy fines or imprisonment for those convicted of adulteration. 
6. Encouragement for Organic Farming: Encourage natural and organic farming practices that reduce pesticide and chemical use.
