Starch Powder
Starch Powder (Product Code: SCL-975/230) is an analytical reagent grade carbohydrate powder used to prepare starch indicator for iodine titrations and to run food tests in school and college laboratories. Even a trace of iodine turns it an intense blue-black, so chemistry departments use it at titration end points and biology teachers build it into the enzyme experiment kit for school practicals; it comes as a 500 gm pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Starch Powder Used For?
To make the indicator, a small amount of starch is stirred into a smooth paste with cold water and poured into boiling water, then heated briefly until the liquid turns translucent and allowed to cool. A few drops in an iodometric or iodimetric titration give a sharp change between blue-black and colourless at the end point, far easier to judge than the fading yellow of iodine alone. The prepared solution supports mould growth, so most laboratories make a fresh batch for each practical session.
In biology and home-science practicals, starch is the reference substance for the iodine food test and the starting material for digestion experiments. Students mix a starch suspension with saliva or diastase, remove drops at timed intervals onto a white tile with iodine until the blue colour no longer appears, and then confirm the sugar formed using Benedict solution, a combination that school laboratories in India repeat every year. Starch is of low hazard, but avoid raising dust clouds when weighing and keep the container sealed against damp.

Frequently Asked Questions
How long does indicator made from Starch Powder last?
Prepared starch indicator lasts only a short time, because the solution supports mould growth and loses sensitivity. Make a small fresh quantity from Starch Powder for each practical session rather than storing a large bottle of made-up indicator.
Why does the blue colour fade when Starch Powder indicator is warm?
Because the starch-iodine complex breaks apart on heating and re-forms on cooling. Titrations that use indicator made from Starch Powder should therefore be carried out at room temperature to keep the end point sharp and reliable.
Is Starch Powder the same as soluble starch?
This product is listed as Starch Powder, and the listing does not describe it as soluble starch. If your method specifically calls for soluble starch, contact us before ordering so we can confirm which listing suits your procedure.
Can biology departments use Starch Powder for food tests?
Yes. Starch Powder works as the positive control in the iodine food test and as the substrate in amylase digestion practicals, so one pack can serve both the chemistry and biology rooms of a school or college.
What is the shelf life of Starch Powder?
Shelf life depends on the chemical, its grade and storage conditions, so no blanket period is given for this Starch Powder. Ask us for the expiry date of the batch you are quoted, and keep the pack closed in a cool, dry place away from damp.
Who supplies Starch Powder?
Starch Powder is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, in 500 gm packs of analytical reagent grade with an MSDS, for schools, colleges, research laboratories and distributors in India and international markets.
Which vendor details can we use for Starch Powder tenders?
The CIN and GSTIN given in the Supplier section can be entered in vendor forms for Starch Powder. For any further documents your tender requires, share the requirements through the contact form and we will confirm what can be provided.
