AQA Biology GCSE - way to remember food tests?

Having trouble remembering the food tests so anything like an anagram would be helpful thanks.
I just learnt them today aha idk whether I’ll remember them but I’ll try give something a go now.

Reducing sugars - benedicts - goes from blue to green to yellow to brick red.
To remember: “reducing” means there are separate layers or a decrease so it goes through the colours?

Protein - Biuret - blue to purple
I have nothing to protein but in my head protein is ugly and biuret doesn’t sound great but there’s alliteration.

Starch - iodine - orange to blue/black
To remember: if you ever did the test in like year 7/8 with the onion. ‘Eye’ for iodine (eye-odine) will hurt if it’s in your eyes??

Lipids/fat - sudan - bright red layer (like a layer of fat?”


I have no other ideas of how to remember but maybe my crappy analogies might help haha good luck

this is real dumb but it works for me. BP IS ******** SLow.
BP - biuret proteins
IS - iodine starch
BS - benedicts sugar
SL - Sudan III lipids.



although, it's a shame it's not BT instead of BP since that would make more sense.

Even after 4 years, Got my exam tomorrow and will be usefull thanks!!
Oh lol I have my exam tomorrow aswell must have been thinking the same thing. Quite confused by the anogram the bull s** lol

Update: I understand now I'm quite slow :wink:

This is how I fully understand it:

Bip is bs slow
Biuret protein
Iodine Starch
Benedict Sugar
Sudan lipids

I added the bip so I don't get confused between Biuret and Benedict in my frantic brain tomorrow lol

Benedict's turns red, for sugary dread.
Iodine goes black, with starch on the track.
Emulsion turns white, fat takes flight.
Biuret turns purple, protein's the hurdle.
Flame test turns green, copper's the scene!
