Question
### Food Testing for Nutrients **Topic:** Nutrition Testing in Foods Four foods were tested for fat (using ethanol), protein (using the biuret test), reducing sugar (using Benedict’s solution), and starch (using iodine solution). The goal is to identify which food contains both protein and starch. #### Results of Food Tests The results are shown in the table below: | Food | Blue/Black (Iodine) | Purple/Lilac (Biuret) | Brick-Red/Orange (Benedict’s) | Milky-White (Ethanol) | |------|---------------------|----------------------|------------------------------|-----------------------| | A | ✓ | ✗ | ✓ | ✗ | | B | ✓ | ✓ | ✗ | ✗ | | C | ✗ | ✗ | ✓ | ✓ | | D | ✗ | ✓ | ✗ | ✓ | **Key:** - ✓ = Nutrient present - ✗ = Nutrient absent #### Question: **Which food contains protein and starch?** *Options:* - A - B - C - D **Answer:** The correct food that contains both protein and starch is **B**. This table helps in understanding the nutrient composition of different foods by showing which nutrients are present based on the colorimetric changes observed during different biochemical tests.
