Abstract
Mangifera odorata is an underutilised fruit found in Malaysia. This fruit has received much interest due to its delicious taste, attractive colour and highly nutritional value. Unfortunately, studies on the benefits of its waste remain scarce and most information are only limited to the nutritional composition or antimicrobial activity per se. The aim of our study was to evaluate the chemical composition in different parts of waste from this fruit. The sugar profile and antinutritional factor composition from its kernel and skin was evaluated via HPLC-ELSD and spectrophotometry method. Analysis of sugar profile revealed that these parts of waste contain considerable amount of fructose, glucose, and sucrose (2.40 to 4.41 mg/100 g in kernel and 3.66 to 6.48 g/100 g in skin). The antinutritional factor content from M. odorata waste, namely phytic acid and tannic acid, were in the acceptable range for both part (0.04 – 0.44 mg/100 g in kernel and 0.02 to 0.44 mg/100 g in skin), respectively. These preliminary results were promising and has fortified our confidence in the potential to utilise this inexpensive source as a food ingredient. Still, further work needs to be conducted extensively to maximise the use of this fruits as a premium food ingredient.
