Red litmus paper turns blue under basic or alkaline conditions.

Purple litmus paper is neutral.

At pH levels of 0.0 to 4.5, the solution turns a red color;

At pH levels of 8.3 to 14.0, it turns a blue color.

Explanation

Higher reducing sugar in Fruit Jelly may result in the crystallization of glycerol

The addition of glycerol and glucose syrup increased the equilibrium moisture content

and reduced sugar crystallization significantly.

Explanation
