Good morning sir or mam In this experiment we'll be doing the testing of food stuffs. Our interest is to test the presence of starch, carbohydrates and proteins Sample A, B, C For starch Few drops of iodine in 1 ml ... beautiful violet For carbohydrates (Benedict's reagent ) Blue ---∆-- yellow---orange Cu 2+ to Cu2O Fehlings or Toluenes test 1:1 A:B A (CuSO4 ) 💙 B (KNaC4H4O6.4H2O) 🔵 Sodium potassium tartarate If adding iodine solution remains yellow ...absence of starch Heat Orange yellow Reducing sugar tollens or fehlings (reddish orange) free aldehyde group. For Protein The Xanthoprotic test Conc Nitric acid ---💛 The Biurit test Sodium hydroxide 1percent solun of copper 2 sulphate Turqquoish blue to violet blue

Is this practical for people who have taken food nutrition ...i am in 11 th . and randomly found the video.. but my sub is food nutrition so please tell
Hi Mam, thank you so much for the wonderful session!! Can u please provide some resources where we can find how to check percentage of protein and carbs
Ma’am can we do molisch test also to confirm the presence of carbohydrates? And we were told to do these exps in water bath is it make any difference ?
@@seemamakhijani721 Mam, I did my Chemistry board practicals well yesterday,salt analysis-lead acetate, volumetric analysis Mohr's salt and protein food stuff. Thank you very much Mam for all your practical videos (the experiments you performed & some performed by your students in chemistry laboratory) which served greatly in my preparation

If adding iodine solution remains yellow ...absence of starch
Heat Orange yellow
Reducing sugar tollens or fehlings (reddish orange) free aldehyde group.
For Protein
The Xanthoprotic test
Conc Nitric acid ---💛
The Biurit test
Sodium hydroxide
1percent solun of copper 2 sulphate
Turqquoish blue to violet blue
For protein you had written copper hydroxide while it's sodium hydroxide we use in biuret test
Protein biuret test gives dark blue
