Nutritional composition of some fruits harvested in the ripening period cultivated in Vietnam

Fruit is an important source of nutrition for humans as well as medicinal value. This article presents the nutritional composition of popular fruits cultivated in Vietnam (mango, cucumber, guava, custard apple). When ripe, these fruits had specific flavors and colors with high nutritional content. While custard apple, mango and guava contained a high content of vitamins, proteins, lipids and sugar, the highest amino acid content was found in cucumber, followed by guava, custard apple and mango. The main amino acids are glutamic acid, aspartic acid, and leucine. In addition, these fruits exhibited a high mineral content, mainly phosphorus, nitrogen and magnesium. The results are served as scientific basis for harvesting, preserving and consuming fruits in Vietnam as well as around the world.
