14:54 Sucrose(which is dextrorotatory) is known as invert sugar because upon hydrolysis it breaks down into Fructose (laevorotatory) and Glucose (dextrorotatory). The specific rotation value of Fructose is more than glucose due to which the mixture overall is laevorotatory. So, basically dextrorotatory sucrose converts to laevorotatory mixture on hydrolysis (inversion of optical activity) and hence is called invert sugar.
