Test for Carbohydrates:

1.Molisch’s test – Given sample food + Molisch’s reagent → Purple or violet ring confirms the presence of carbohydrate.

Test for Oils and Fats:

1.Solubility test – Given sample food + Chloroform or alcohol → Miscible with chloroform and immiscible with water the fat presence is confirmed.

Answer:

Test for Carbohydrates.

There are many types of carbohydrates. The main carbohydrates found in our food are in the form of starch and sugars. We can easily test if a food item contains starch.

Take small quantity of the food items to be tested.

Put 2-3 drops of iodine solution on it.

Observe the colour of the food item.

Blue-black colour indicates the presence of starch in the tested food item.

Test for Fats

Fat is a major source of energy and also aids your body in absorbing fat soluble vitamins. You need a minimum of 10 to 20 percent of your overall calories as fat .Test if a food item contains fat.

Take a small quantity of the food item to be tested.

Wrap the food item in a piece of paper and crush it.

Straighten the paper.

Dry the paper by keeping it in sunlight for a while.

Observe the paper.

An oily patch on the paper indicates the presence of fats in the tested food item.
