===Meaning===
'''Starch ''' is a complex [[carbohydrate]] found in food.
===About Starch===
: '''Starch ''' is made of many [[glucose molecules bonded ]] [[molecule]]s [[bond]]ed together.: '''Starch ''' is an important part of a [[Balanced Diet|balanced diet]].

====Testing for Starch====
: '''Starch ''' can be detected using [[Iodine Solution]].
=====Method=====
: 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]].

===Meaning===
'''Starch''' is a [[polysaccharide]] found in food.
===About Starch===
: '''Starch''' is a [[polymer]] made of many [[glucose]] [[monomer]]s which join together in a [[polymerisation|polymerisation reaction]].
: '''Starch''' is an important part of a [[Balanced Diet|balanced diet]].
: '''Starch''' can be broken down into shorter chains by [[amylase]].
