'''Starch ''' is a complex [[carbohydrate]] found in food.

: '''Starch ''' is made of many [[glucose molecules bonded ]] [[molecule]]s [[bond]]ed together.: '''Starch ''' is an important part of a [[Balanced Diet|balanced diet]].

: '''Starch ''' can be detected using [[Iodine Solution]].

: 1. A small sample of food is placed on a [[Spotting Tile|spotting tile]].: 2. A drop of [[Iodine Solution ]] is added to the food sample.: 3. If the [[Iodine solution Solution]] turns from orange to blue-black then the food contains [[starch]].
