Glucose, TSS and nutrient content of dates, mango, apple and banana: A comparative study

Abstract

Dates, mango, apple and banana fruitsare the prime fruit crops in Saudi Arabia as well as all of the world. Fruit is mostly used as fruit, juice and source of different types of food products. These are traditional and common fruit with the health benefits and nutritional value. The study was carried out to investigate the carbohydrate content as represented by glucose, total soluble solids and micro-macro nutrient content in different fruits. Ten fruit of dates, banana, apple and mango were thoroughly washed with distilled water, cut using a sterile knife and were blended. Then the juice samples were filtered and kept in the freezer to analyze. Fruit glucose content was found higher in dates and apple than in mango and banana. However, pH content was found higher in dates and banana than in mango and apple. Moreover, total soluble solids (TSS) content was the highest in dates. P, Ca and K content were higher in dates compared to the mango, apple and banana. Mg content was the highest in banana. Comparatively more micronutrient was found in dates than in mango, banana and apple. The highest correlation was found in dates with glucose and fruits varieties. The results conclude that dates and banana contain better biochemical (glucose, TSS and pH) than apple and mango as well as nutrient content was better in dates and mango than banana and apple.
