The Maillard reaction, which is a chemical reaction between amino acids and reducing sugars, can cause a purple or mauve color to develop in certain foods. This reaction occurs when reducing sugars and amino acids are present together at high temperatures, leading to the formation of pigmented compounds that produce the purple or mauve color.
What else can I help you with?
What colour would water turn if you added litmus?
I think it is supposed to be PURPLE. Because of the following:It turns red when placed in acidic solutionIt turns blue when placed in alkaline solutionAnd purple when placed in neutral.
How do you differentiate between reducing and non reducing sugar?
Add benedicts solution to the sample you are testing, heat gently for 5 minutes, and if reducing sugars are present, the solution turns red (if concentration of reducing sugars is high) and if its not as high it could turn green-yellow-brown ish the closer to red, the higher the concentration of reducing sugars. it will stay blue if none are present
What colours does ph paper turn in alkalis?
pH paper turns blue or purple in alkalis.
Why does litmus turn purple?
Litmus paper turns purple in a basic solution due to a chemical reaction with hydroxide ions in the solution. The dye in litmus paper undergoes a change in structure when it comes in contact with a base, causing it to reflect purple light.
What metal is used when the flame turns purple?
Potassium although sometimes it can look purple
What is the natural colour of litmus paper?
The natural color of litmus paper is purple. It turns red in acidic solutions and blue in basic solutions.
What is the indicator for carbohydrates?
Simple(sugar): benedicts solution. Turns bright orange. Complex(starch): iodine turns dark purple/black
What is the meaning of going mauve in the face?
Mauve is a dark reddish-purple color.
How do you test for starch or carbohydrate?
take 3cm cubed of the carbohydrate and put in a test tube with 5cm cubed of benedict's reagent. If the carbohydrate is a reducing sugar the solution would turn red. If it contains a non- reducing sugar the solution would remain blue. Then take the non-reducing sugar boil it with dilute hydrochloric acid, cool it and neutralise it with sodium hydrogencarbonate and retest with benedict's reagent if the soultion turns red it means the non- reducing sugar has been hydrolysed to its monomers.If it remains blue there is no reducing sugar present. take 3cm cubed of the carbohydrate and put in a test tube with 5cm cubed of benedict's reagent.

Benedict's turns orange when heated in the presence of a?
reducing sugar. Benedict's reagent is a solution used to test for the presence of reducing sugars, which includes glucose and fructose. The color change to orange indicates a positive result for the presence of reducing sugars in the substance being tested.
What biomolecule turns Benedict's solution purple?
Reducing sugars, such as glucose and fructose, can turn Benedict's solution purple upon heating. Benedict's solution is a chemical reagent used to test for the presence of reducing sugars in a given sample.
What turns purple when sprayed with bleach?
Red cabbage juice turns purple when sprayed with bleach.
What colour would water turn if you added litmus?
I think it is supposed to be PURPLE. Because of the following:It turns red when placed in acidic solutionIt turns blue when placed in alkaline solutionAnd purple when placed in neutral.
Does sugar turn blue when mixed with iodine?
Yes, sugar does not turn blue when mixed with iodine. Iodine reacts with starch, turning it into a blue-black color. Sugar does not contain starch, so it will not have a reaction with iodine in this way.
If benedicts reagent turns red what substance is present?
If Benedict's reagent turns red after adding it to a solution, it indicates the presence of reducing sugars such as glucose or fructose. The red color is a result of the reduction of copper (II) ions in the reagent to copper (I) oxide by the reducing sugars.
What if it turns purple is it an acid?
No, If it is purple, it is a strong alkali e.g. oven cleaner
How do you get the purple off on the computer when you click on something and it turns the color purple?
