The enzyme which is added to baby foods to predigest them is

Options

A. zymase
B. protease
C. streptokinase
D. trypsin

Answer

To answer the question regarding the enzyme added to baby foods to predigest them, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Purpose**: Baby foods are often designed to be easily digestible for infants. This means they may require enzymes that can break down complex molecules into simpler forms that babies can digest.

2. **Identifying the Enzyme**: The enzyme that is commonly added to baby foods for this purpose is **chymosin** (also known as rennin). Chymosin helps in the digestion of milk proteins, making it easier for infants to process the food.

3. **Reviewing Other Options**:
- **Xymase**: This is a mixture of enzymes from yeast that assists in the fermentation of sugars, not relevant to baby food digestion.
- **Protease**: While this enzyme breaks down proteins, it is not specifically used in baby foods for predigestion.
- **Streptocymase**: This enzyme is used to dissolve blood clots and is not related to the digestion of baby food.

4. **Conclusion**: Based on the above analysis, the enzyme that is added to baby foods to predigest them is **chymosin**.

### Final Answer:
The enzyme which is added to baby foods to predigest them is **chymosin**.
