Polished rice has less protein due to

Options

A. Removal of aleurone layer
B. Denaturation of protein by polish
C. Heat treatment that causes destruction of proteins
D. Both B and C.

Answer

**Step-by-Step Solution:**

1. **Understanding Polished Rice**: Polished rice refers to rice that has been processed to remove the outer layers, including the bran and germ, to achieve a smoother and whiter appearance.

2. **Identifying the Alluron Layer**: The alluron layer is a thin layer of protein-rich tissue that surrounds the endosperm of the rice grain. It is crucial for the nutritional content of the rice.

3. **Effects of Polishing**: During the polishing process, manufacturers remove the bran and the alluron layer. This process is intended to enhance the aesthetic appeal of the rice but also results in the loss of essential nutrients.

4. **Protein Content Reduction**: The removal of the alluron layer leads to a significant decrease in protein content because this layer contains protein bodies that are beneficial for nutrition.

5. **Conclusion**: Therefore, polished rice has less protein primarily due to the removal of the alluron layer during the polishing process.

**Final Answer**: Polished rice has less protein due to the removal of the alluron layer.
