Chemical reactions are really important for keeping food safe, fresh, and tasty. Here are some key points that show just how they work:
Fermentation: This process uses tiny living things called microorganisms to change sugars into acids or alcohol. For example, in making yogurt, lactic acid is produced. This lowers the acidity level, which helps stop spoilage bacteria. Research shows that lactic acid can kill over 90% of harmful germs in food.
Oxidation-Reduction Reactions: Antioxidants, like vitamin C and vitamin E, work to stop fats from going bad. By adding these antioxidants to food, you can make fats last about 30% longer.
Canning: This method uses heat to kill germs that can spoil food. If food is canned at a temperature of 121°C for just 3 minutes, it can greatly reduce harmful bacteria like Clostridium botulinum, which can produce toxins.
Pickling: Adding vinegar (which is acetic acid) makes the food acidic. This helps stop the growth of germs. Studies show that keeping the acidity below a certain level (pH 4.6) can effectively keep bad germs away.
In 2022, the food preservation industry was worth about 215 billion. This shows how important food preservation techniques are from an economic point of view.
According to the Food and Agriculture Organization (FAO), about one-third of food produced worldwide gets wasted. But with the right preservation methods, we could reduce food waste by up to 50%.
By learning about these chemical reactions and using them wisely, we can make food safer, keep it fresh longer, and help reduce waste. This is not only good for our health but also helps the economy and the environment.
