Explanation

To answer the question "In cockroach, food is crusted into fine particles inside," we need to analyze the digestive system of the cockroach and identify where this process occurs.

### Step-by-Step Solution:

1. **Understanding the Digestive System of Cockroach**:
- The cockroach's digestive system is divided into three main parts: the foregut, midgut, and hindgut.

2. **Identifying the Foregut**:
- The foregut includes the mouth, pharynx, esophagus, crop, and gizzard. The gizzard is the last part of the foregut.

3. **Role of the Gizzard**:
- The gizzard is a muscular structure that contains chitinous teeth. It is responsible for grinding and crushing the food into fine particles.

4. **Process of Food Digestion**:
- Food enters through the mouth, passes through the pharynx, and then moves into the esophagus and crop for storage. Afterward, it reaches the gizzard, where it is crushed into fine particles due to the action of the chitinous teeth.

5. **Conclusion**:
- Since the question asks where food is crusted into fine particles, the correct answer is the gizzard, which is part of the foregut.

### Final Answer:
**The food is crusted into fine particles inside the gizzard.**
