I still remember in 2020 during online school when our teacher made us watch this video during class. Makes me nostlagic. Until today it's useful for me and I'm using it for quick revision in 12th grade for my combined science exam, it's excellent for jogging memory. Thank you for this straightforward video!

For reducing sugars you can also use Sudan 3 which separates the oil from the water, leaving the oil on top in a red colour.

[@fionawatson7691]

Sudan III is a lipid test not a reducing sugar test. Otherwise you are correct but emulsion test is a better one.

There is also the Fehling's test, also used to test for glucose. Fact: Both the Benedict's test and the Fehling's test was used to detect the amount of glucose in the urine of diabetics. Actually, they use a colorimetric chart to tell the amount of glucose in the urine.

looking for DCPIP for Vitamin C test. what is this and where can i get it?

[@satishnikam6221]

You can even take a food item, wrap it in paper and just rub the paper. The paper would turn greasy and a bit translucent if the food item has fats. This test is far more easier than the one you did.

[@muhammadfarhan3341]

Thats true, but IGCSE demands you to use the emulsion test to test for fats 🤷‍♂️

why do u have to pour the biuret solution on top of the protein suspension, basically y does it have to form a layer on top before mixing?

[@Science_Sauce]

It doesn’t. In the experiment in the video I used egg white which is very thick so the solutions didn’t mix until shaken or stirred. It’s not necessary for that to happen when testing for proteins, however.

+Bella Yip Add water and mash it up, then do the test like normal. As for peels, yes, they need to be removed if doing food tests as you want to test the edible part of the food. Hope this helps.

what if the food is solid? do i have to crush it and take the moisture out from the food sample? i hope you can answer this quickly. i have a practical for food test on monday haha

[@afsanaferdousi786]

Zahirah Ramlan if the food is solid, ex: potato which contains starch, it'd still show changes when iodine solution is added. however, you are always supposed to use liquid samples in exams as changes won't be visible in solid state. You won't need to sample solid in exams or elsewhere.

[@Science_Sauce]

+Zahirah Ramlan that's right, you'll need to crush the sample if it's solid, and in most cases in a practical exam a liquid sample is necessary. Good look with your practical on Monday!

Biuret only tests for proteins. Carbohydrates are not proteins, they are sugars or starches, so you can use benedict reagent.

[@ahmedhayat9532]

YEP IT IS SOOO USEFULL

[@zoeyteo7602]

is it a must to use distilled water for the ethanol emulsion test in exams or?? :)

[@Science_Sauce]

+Zoey TMH technically, yes. Distilled water is pure, but "normal" water (eg tap water) contains impurities which may affect your experiments, so all laboratory work involving water should require distilled water. In reality, tap water would work fine for this experiment (but you should specify "distilled water" for exams, just to be safe).

[@zoeyteo7602]

Science Sauce thank you very much!!

[@bigdaddydanz7967]

why do we need to include water in this experiment?

[@Science_Sauce]

It’s used as a control, to confirm that any observable changes are the result of a biological molecule.
