β¨ STUDY HIGHLIGHTS
This research investigated how processing delays affect coconut sap and coconut sugar, particularly their physicochemical properties, crystallization behavior, production yield, and color quality.
π¬ Key outcomes include:
βοΈ Morning-collected coconut sap showed higher average volume and distinct physicochemical characteristics compared with afternoon-collected sap.
βοΈ Processing delays influenced the crystallization kinetics of coconut sugar, as evaluated using the Avrami model.
βοΈ A 1-hour processing delay yielded the highest coconut sugar yield (69.00 Β± 0.12%) and the fastest crystallization rate among the tested sap-delay conditions.
βοΈ Longer processing delays were associated with changes in pH, sugar concentration, and color, reflecting changes occurring in the raw material during processing delays.
βοΈ Increasing processing delays resulted in greater browning, with the 2-week delay showing the highest browning index among the tested conditions.
βοΈ The study established a color-based grading system from Grade A to Grade F, ranging from cream white to dark brown, using browning index as a basis for coconut sugar quality assessment.
π WHY THIS MATTERS
Coconut sugar production in the Philippines remains largely artisanal, with variations in raw material collection and processing practices contributing to differences in product quality and production efficiency. This study provides scientific evidence on how processing timing, crystallization behavior, and physicochemical changes can influence coconut sugar production.
The developed color grading system may also provide a framework for quality assessment and product differentiation, supporting efforts toward improved standardization and commercialization of coconut sugar.
π΄ From coconut sap to a standardized, value-added product β this research contributes to food processing innovation, quality assessment, and the continued development of the Philippine coconut industry. π΅ππ₯₯
π ACKNOWLEDGMENT
This research was supported by a grant from Winrock International and the U.S. Department of Agriculture (USDA).
The authors express their sincere gratitude for this support, as well as to the coconut sap tappers from Balingasag, Misamis Oriental, and the LAMPCO (Linabu Agrarian Multi-purpose Cooperative) for their active cooperation in this study.
Their cooperation was an important part of the research, particularly in the collection and study of coconut sap used for the investigation.
