Abstract
The contributions and importance of the water-in-oil-in-water (W1/O/W2; W1:W2 = 40:60; W1/O: W2 = 20:80) type double emulsion (DE) to the physicochemical characteristics of almond-based gel were identified in this study. This study investigated from two perspectives: 1) the effect of the amount of DE addition on the gel properties of almond-based yoghurt and 2) the comparison between samples made with and without DE. The hardness, water holding capacity, and viscosity value of almond-based gel increased when the DE addition increased from 5, 10, 20, to 30 % due to the composition variance. Comparing the sample made with DE structure and made without DE, a significant difference was only found between samples incorporated with 30 % DE (D30) and its counterpart control sample C30. A significantly higher (p < 0.05) apparent viscosity and hardness values were observed in sample D30 (0.27 Pa·s; 18.25 g) compared to its counterpart control sample C30 (0.21 Pa·s; 15.09 g). A sensory evaluation revealed similar preferences for both samples (D30 and C30). In summary, the presence of a double emulsion structure contributed to the improved texture, microstructure and quality of almond-based gels. This approach can potentially guide the future production of double emulsion-incorporated plant-based gels.
期刊介绍:
Food Structure is the premier international forum devoted to the publication of high-quality original research on food structure. The focus of this journal is on food structure in the context of its relationship with molecular composition, processing and macroscopic properties (e.g., shelf stability, sensory properties, etc.). Manuscripts that only report qualitative findings and micrographs and that lack sound hypothesis-driven, quantitative structure-function research are not accepted. Significance of the research findings for the food science community and/or industry must also be highlighted.
