Action of saliva on starch | Digestion | Biology
Starch is a component in many foods. When iodine is added to starch it turns blue. That is why, in the experiment, the solutions in both beakers turn blue. On addition of saliva which contains an amylase, a starch digesting enzyme (chemical compound that catalyses the breakdown of starch); the starch gradually converts to sugar. Once the starch is broken down, the blue colour disappears. It is important to know that the salivary amylase requires an alkaline medium to act.

Amazing experiment. I did this when I was in school when I spat saliva into the beaker everyone looked at me creepily.

Very helpful video and Thank u !
You are the man.....But in my son's school they are doing it with control and experiment tubes..,can't get the funda in that one
Thank you sir please do the so many videos in science experiment
and how different biofibers or biomaterials react with saliva
what is the colour of solution after the conversion of starch to sugar molecules??
Excellent presentation
I can't believe this really helped me
I subscribed to your channel because I have understood what you are saying is so easy to learn
you could have just added iodine after a brief amoun of time
Thank u so much sir i understand clearlyy😍😍😍😍

If a water is warmed when colour change in blue black
We have an experiment like this one. But because we don't have a starch powder in the house. So I decided to use potatoes instead and it didn't work so well. But anyway thanks for this 🧡
Thanks Sir 🙂✨
thx mate
How did I end up here? Well, TIL i leanred something new anyway.
why you add same amount of saliva and starch
When you get stuck rice at the bottom of the pan and you tried so hard to remove them, next time you know what to do.
