Question

Answer

Answer

Most fruits and vegetables spoil easily because of damage caused by microorganisms. Microorganisms such as bacteria, yeast and molds need water and nutrients for growth, energy and reproduction.

Answer

**Explanation:**

**Bacteria present in food**

One of the main reasons why food gets spoiled after some time is because of the presence of bacteria. Bacteria are microscopic organisms that can be found everywhere, including in the air, soil, water, and even on our skin. They are also present in the food we consume.

When bacteria come into contact with food, they begin to multiply and grow rapidly. They feed on the nutrients present in the food, breaking it down and causing it to spoil. As the bacteria multiply, they produce waste products and enzymes that further contribute to the spoilage process.

Different types of bacteria have different effects on food. Some bacteria produce toxins that can cause food poisoning, leading to symptoms such as nausea, vomiting, and diarrhea. Others may produce gases that cause food to have a foul smell or taste.

**Other factors**

While bacteria are the primary cause of food spoilage, other factors can also contribute to the process. These include:

1. **Air**: Exposure to air can accelerate the spoilage of food. Oxygen in the air can react with the nutrients in the food, leading to chemical changes that affect its taste, texture, and appearance.

2. **Temperature**: Temperature plays a crucial role in the growth and multiplication of bacteria. Most bacteria thrive in warm, moist environments. When food is stored at temperatures between 40°F (4°C) and 140°F (60°C), known as the 'temperature danger zone,' bacteria multiply rapidly, increasing the chances of food spoilage.

3. **Moisture**: Moisture provides an ideal environment for bacterial growth. Foods with high water content, such as fruits and vegetables, are more susceptible to spoilage. Moisture can also promote the growth of mold, yeast, and other fungi, which can spoil food.

4. **Cross-contamination**: Cross-contamination occurs when bacteria from one food item are transferred to another. This can happen through contact with contaminated surfaces, utensils, or hands. Cross-contamination can introduce harmful bacteria to food, increasing the risk of spoilage and foodborne illnesses.

In conclusion, food spoils due to the presence of bacteria, which multiply and break down the nutrients in the food. Other factors such as air, temperature, moisture, and cross-contamination can also contribute to the spoilage process. It is important to handle, store, and cook food properly to prevent bacterial growth and ensure food safety.
