Answer
You could use the Iodine Test to verify if the food in question contains starch. When the iodine solution is applied to the food sample and the color transforms into a significant blue-black, it signifies the presence of starch.
Explanation
## Step 1:Based on what we've learned from the example, we know starch testing is wrapped around various routines dedicated more to Chemistry, rigidly viseing around food and nutrient testing. Starch, being the primary complex carbohydrate used by plants in storing energy, could be tested utilising a specific chemical compound known as Iodine solution.## Step 2:It is crucial to understand the reaction that underpins the reaction between iodine dissolved in water and starch. When they meet, iodine accommodates itself into the helix structure retained by the starch polymer, revealing a drastic colour(view Colour/color according to your country's English) change in the sample to a black-blue being visual evidence to showcase the presence of Starch in given food sample.### Formula: Starch + Iodine *(aq)* → Starch-Iodine complex *(blue-black)*## Step 3:The analytical procedure you would trail to investigate for the presence of starch in food involves the following steps: Firstly introducing iodine solution over the subject food sample, then observe the given change in colour. If the food molds into a distinct blue-black tint, we could confirm that starch is indeed, present in it.
