Answer:
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.
1.Solubility test – Given sample food + Chloroform or alcohol → Miscible with chloroform and immiscible with water the fat presence is confirmed.2.Translucent spot test – Given sample food + rubbed between the folds of filter paper → presence of translucent spot then the presence of fats 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.
