Enhancing sustainability and flavor of waste coconut (Cocos nucifera) kernel and sweet potato (Ipomoea batatas) peels Creamy roll: Extension program guide

Abstract

Waste Coconut Kernels (WCK) and Sweet Potato (SP) peels are considered household wastes for animal feeding. The present study aimed to develop waste coconut kernel and sweet potato peels creamy roll as innovative guides for the Extension program guide. This experimental study used three formulations varying amounts of WCK with 100g, 150g and 200g; SP peels with 150g, 200g, and 250g mixed with milk solution, sugar and unsalted spring roll wrappers. The study focused on investigating the sensory attributes of the creamy roll development across different formulations, assessing its general acceptability in terms of color, flavor, odor and texture, identifying the most preferred formulation (F1, F2, and F3) based on the panel of tasters, and examining if there were significant differences among the product attributes. Based on Data analysis involved calculating weighted means and conducting One-way analysis of variance (ANOVA), the results revealed that F3, consisting of 250g of SP, 200g of WCK, 250g of milk solution, and 180g of sugar, was the most preferred in terms of flavor, odor and texture, with overall means of 3.67, 4.08, and 3.85, respectively. However, F2 was preferred only in color. A significant difference was observed in flavor indicated by a p-value of .042, lower than the predetermined alpha level of .05. Post-hoc analysis indicated differing perceptions between the 35 experienced consumers and 15 food experts. The most preferred formulation had a sensory acceptability rating of “acceptable” with a mean of 3.92. Based on the findings, the 250g SP peels and 200g WCK were adopted as an Extension program guide.
