Study of carbohydrate, biochemical and nutritional value of pineapple, rambutan and grapes

Abstract

Pineapple, rambutan and grapes fruit are the staple fruit crops in Asia, Europe, Ameria and also all over the world. Fruits are mostly used as fruit, juice and source of different types of food products. These fruits are traditional and common fruits having the health benefits and nutritional value. The study was conducted to evaluate the carbohydrate content as represented by glucose, total soluble solids and micro-macro nutrient content in pineapple, rambutan and grapes. Nine fruits were collected from 3 plants for each sample of fruit. Total of 27 fruits were collected for Pineapple, rambutan and grapes. Samples were collected randomly following the completely randomized design. Fruit glucose content was found higher in grapes and rambutan than in pineapple. PH content was found higher in grapes than in rambutan and pineapple. In addition, total soluble solids (TSS) content was the highest in grapes. Potassium content were higher in grapes compared to the pineapple and rambutan. However, Phosphorus content was the highest in rambutan and calcium content was the highest in grapes. Moreover, magnesium (Mg) content was higher in pineapple than in grapes and rambutan. Comparatively more micronutrients were found in pineapple than in rambutan and grapes. Fe, Zn, Na and Mn were found higher in pineapple and rambutan than in grapes. The highest correlation with fruit and TSS was found in grapes followed by rambutan and pineapple. The results conclude that grapes and rambutan contain better biochemical (glucose, TSS and pH) than pineapple as well as nutrient content was better in grapes and pineapple than in rambutan.
