Starch constitutes the major component of the polysaccharides in most foods and consists mainly of amylose and amylopectin. The test sample is dispersed in water and heated in acidic solution to hydrolyse the starch, releasing the sugars. The resulting sugars are then determined by titration with Fehling solution according to the method of Lane-Eynon. The sugar content is further converted into Starch content of that sample. This video represents a detailed procedure for the determination of total starch content of a food sample by Acid Hydrolysis Method.

Can you do a video explaining the formula used? Where does the 0.9 come from? 10:09

Hello i really need your help. I want to make an acid hydrolysis of proteins. Can you please tell me a method to do this? I know the most common is with hydrochloric acid but i want to learn the method. Thanks

I want to ask, for the solution that needs to be tested for the total sugar method, is it the solution needs to do it immediately, or can wait for a few days?

so to get the starch content, just only times with 0.9? why 0.9? may i know

@MicroChemsExperiments Жыл бұрын

The reference method said so.

Hello! What specific type of reflux condenser is used in this process? Can we use the liebig type of reflux condenser? Or does it have to be the same design and type?

@MicroChemsExperiments Жыл бұрын

Any reflux condenser what will facilitate the condensation is applicable
