ASSESSMENT OF THE PHYTOCHEMICAL CONSTITUENTS, NUTRITIONAL COMPOSITION, AND MINERAL COMPOSITION OF WATERMELON SEED AND RIND
Abstract
This research investigated the phytochemical composition, nutritional value, and mineral content of watermelon (Citrullus lanatus) seed and rind to evaluate their potential as functional food ingredients and alternatives to agricultural waste. The study employed standard analytical methods including qualitative phytochemical screening, proximate nutritional analysis, vitamin determination, and mineral content assessment using established AOAC procedures. The research began by examining the background of watermelon cultivation and the widespread disposal of seeds and rinds as agricultural waste, despite their potential nutritional and economic value. Literature review established the scientific foundation for valorizing these by-products based on their reported bioactive compounds and nutritional components.
Chapter One
Watermelon (Citrullus lanatus) is a tropical and subtropical fruit extensively cultivated and consumed worldwide due to its refreshing taste, high water content, and nutritional value. Traditionally, emphasis has been placed on the red or pink pulp of the fruit, which is primarily consumed fresh or processed into juice, jams, and other edible forms. However, the rind and seed, which constitute a substantial portion of the fruit's mass, are commonly discarded as waste, despite their potential as rich sources of nutrients and bioactive compounds
