What is the purpose of starch in food?
In food products, the functional roles of starch could be as a thickener, binding agent, emulsifier, clouding agent or gelling agent. In the food industry, native starch is usually reprocessed and modified through chemical processes to improve its functionality for the desired purpose.
What happens when we eat starch?
When starch is consumed, it dissolves into glucose molecules with the help of molecular machines, known as enzymes. Specifically, enzymes called amylases aid in breaking starch into glucose with the help of water.
What are the benefits of starch?

How do you identify starch in food?
A chemical test for starch is to add iodine solution (yellow/brown) and look for a colour change. In the presence of starch, iodine turns a blue/black colour. It is possible to distinguish starch from glucose (and other carbohydrates) using this iodine solution test.
Why starch is a useful energy store?
Starch is better than glucose for storage because it is insoluble. Both glucose and starch can be converted into other substances. These can then be used for energy, growth and other storage products. A plant also produces oxygen as a waste product of photosynthesis.
Why is starch good for the body?
Starches are stored in muscles as glycogen and used for exercise. When you eat a starch, your body uses it right away to fuel your fast-paced life or stores it in your muscle, liver or fat cells for energy in between meals.
