Organoleptic Quality Attributes of Three Different Types of Vegetable-Based Milk Analogs Supplemented with Hibiscus Oil

Abstract

Hibiscus is rich in acids, anthocyanins, flavonols, oils, proanthocyanidins, and various pigments. It is utilized for medicinal purposes, to improve human health, and as a galactagogue to stimulate milk production in cows. Due to its biofunctional activities, hibiscus oil has broad applications spanning different fields. This study analyzed the pH and organoleptic quality attributes of three different vegetable-based milk analogs supplemented with hibiscus oil at 0% – 1.5% concentrations. The results revealed that the addition of hibiscus oil did not affect pH; however, as the concentration of the hibiscus oil increased, the organoleptic quality attributes of the milk analogs supplemented with it decreased. All three milk analogs supplemented with 0.25% hibiscus oil demonstrated favorable attributes compared to the control group. This study provides valuable foundational data for developing new vegetable-based milk analogs that possess enhanced biofunctionality through the supplementation of hibiscus oil.
