Oxidation and Poisoning
Food chemistry is a complex discipline that involves numerous chemical reactions, some of which can be harmful to human health. One of the most important reactions is oxidative deterioration. Oxidation can produce harmful and toxic compounds in food, severely compromising its safety, sensory quality, and nutritional value.
What is Oxidation?
Oxidation occurs when a substance combines with oxygen and undergoes a chemical change. This process can be either beneficial or harmful.
Examples of Oxidation:
- Metal getting rusty
- Cut fruit turning brown (like an apple)
- Food becoming spoiled
Oxidation can be:
- Good: It helps our bodies function properly.
- Bad: It damages cells and causes food spoilage.
Why is Oxidation Harmful?
When oxidation affects food, it can:
- Cause food spoilage
- Create harmful substances that may affect health
- Reduce nutritional value
- Change taste, color, and texture
What Helps Stop Oxidation?
Free radical scavengers (Antioxidants) help prevent oxidation. Antioxidants are compounds that protect our bodies and food by neutralizing harmful free radicals. They act as protective agents that prevent internal damage and promote overall health and well-being.
How Antioxidants Work:
- Prevent cell damage
- Reduce the risk of illness
- Support overall health and vitality
What is Poisoning?
Poisoning refers to the harmful effects that occur when a toxic substance enters the body. This can interfere with normal body functions. Poisoning can occur through:
- Ingestion (eating or drinking contaminated substances)
- Inhalation (breathing in toxic gases or chemicals)
- Skin contact (touching harmful substances)
Common Causes of Food-Related Poisoning
- Eating spoiled or contaminated food
- Drinking unsafe water
- Touching or handling contaminated items
Symptoms of Poisoning
- Nausea or vomiting
- Weakness or dizziness
- Abdominal pain
- General discomfort
What to Do in Case of Poisoning?
- Call for medical help immediately
- Inform a responsible adult or authority
- Seek professional medical treatment
“When food is exposed to air, it begins to spoil.”
Ways to Prevent Food Spoilage
- Store food in airtight containers
- Keep food refrigerated or frozen
- Remove air from packaging (vacuum sealing)
- Add safe antioxidants to food products
- Cook and handle food properly
Why Keeping Food Fresh is Important
- Prevents foodborne illness
- Maintains nutritional value
- Preserves taste and quality
- Ensures food safety
Conclusion
Oxidation is a natural chemical process that can negatively impact food quality and human health if not properly controlled. However, by understanding oxidation and practicing proper food storage and handling methods, we can reduce the risk of food spoilage and poisoning. Keeping food fresh is essential for maintaining health, safety, and nutrition.
Remember: Oxidation can be harmful, but with proper care and storage techniques, we can effectively prevent food spoilage and protect our health.
