Determination of sugars and organic acids in fruits

Benefit description

Sugar contents (glucose, fructose and sucrose) are major factors for fruit flavour. The contents of sugars of fruits are highly dependent on the developmental stage and ripeness. Determination and quantification of main sugars (glucose, fructose and sucrose) is done through an enzymatic reaction. Organic acids contents are major factors for fruit flavour. The contents of organic acids of fruits are highly dependent on the developmental stage and ripeness. Malic acid is the main acid in many fruits, including apricots, blackberries, blueberries, cherries, grapes, peaches, pears, plums, whereas citric acid is the main acid in fruits such as lemon, limes, oranges, grapefruit, strawberry and pineapple. Determination and quantification of main organic acids is done through an enzymatic reaction.
