Comparative Evaluation of Proximate Composition of Mango Seed Endosperm of Two Different Mango Varieties.

This study focused on the comparative evaluation of the proximate composition of the seed endosperm of two mango varieties: Alphonso mango (Ofaneze mango) and Sweet mango (Sheri mango) obtained from Ebonyi State, Nigeria. The Objective of the study was to assess the nutritional potentials of this huge waste (mango seeds). The proximate components were analyzed using the AOAC (2018) and include moisture, protein, fat, fiber, ash, carbohydrate (CHO), and energy value. The results reveal that the seed proximate composition of both mango varieties did not differ significantly (P>0.05) in Moisture, fat, fiber, Carbohydrate content as well as in Energy value. The results However showed significant difference in their protein content with Sweet mango showing higher values in protein (8.9%) than the Alphonso Mango in protein (7.8). Alphonso mango on the other hand had much higher ash content (7.5%) compared to Sweet Mango with Ash content (2.7) (P= 0.002). Both varieties exhibited low moisture content, which is beneficial for extended shelf life, and a relatively high carbohydrate content, indicating their potential as energy sources. The seeds also demonstrated moderate fat and protein content, supporting their use in lipid-based applications and as a source of plant-based proteins. The findings suggest that mango seed endosperms from both varieties could be utilized interchangeably in food industries, contributing to food security and reducing waste. The bioactive compounds present in these seeds also hold potential for use in nutraceuticals, pharmaceuticals, and cosmetics. This study aligns with global sustainability efforts of promoting the valorization of agricultural by-products, fostering economic growth, and supporting environmental conservation and revealed that mango seed endosperms of Alphonso and Sweet mango varieties represent underutilized resources with significant nutritional, economic, and industrial potentials,warranting further exploration in future studies.
