Question

How will you determine whether the given food items contain protein or not?​

Answer 1

Answer:

A Violet color solution confirms the presence of proteins. Note: Biuret reagent solution can be prepared from copper sulfate, sodium/potassium hydroxide, and sodium tartrate. The above mentioned tests can be used for the different food materials and ease of the process.

Answer 2

You determine whether the given food items contain protein or not

1)Grab a little sample of the food that will be examined.

2) Pulverize or mash the meal.

Put the food item into a test tube in step three.

4) Shake the test tube after adding 10 drops of water.

5) Using a dropper, add two drops of copper sulphate solution to the test tube.

6) Using a dropper, add 10 drops of the caustic soda solution, then shake the test tube.

7) Wait a few minutes while the test tube is resting in a test tube stand.

8) Check out the mixture's colour.

9) The colour violet indicates that the food item under test contains proteins.

• Plant-based foods (fruits, vegetables, grains, nuts, and seeds) frequently lack one or more essential amino acids, but animal-based foods (meat, chicken, fish, eggs, and dairy products) are frequently good sources of complete protein.
• As you can see, rice doesn't contain a lot of protein. Only 3.5 g, or the equivalent of 0.5 oz, of chicken breast, are present in it. I usually advise at least 7 g of protein per serving size for rice to be regarded as a high protein food.
