Fruit sweetness is an important aspect of fruit quality.Glucose
and fructose are the most predominant sugars present in all fruits
including the mango fruit.Sugars and acids in fruits significantly
influence the flavour,appearance,chemical and sensory characteristics.Most of the available literature describes the titration
based Lane–Eynon method for the determination of sugars in fruit
juices (Shahbaz et al.,2014). However,titration methods have several disadvantages such as the final results largely depend on precise reaction times,temperature and reagent concentration.
In addition, the method is susceptible to in terference from other
types of molecules that act as reducing agents.In the present investigation,spectroscopic procedures based on a calorimetric
technique including the phenol sulphuric acid assay and Somogyi-Nelson method were used to quantify the amount of total sugars and reducing sugars.respectively.
