Assessment of melting kinetics of sugar-reduced silver ear mushroom ice cream under various additive models

Abstract

This study focuses on assessing the effects of various food processing silver ear (Tremella fuciformis) powders in sugar-reduced ice cream through melting kinetic simulation, sensory properties and functional ingredients. T. fuciformis, a natural anti-melting stabilizer in ice cream, has the advantage of functional ingredients. Using 100, 200, and 300 mesh of particle sizes, and then selecting a suitable particle size, those are added to the additive ratios of 0.4, 0.9, and 1.4% T. fuciformis powder to replace fresh T. fuciformis fruit body. Decreased particle size of T. fuciformis powder significantly increased ice cream stability. Comparisons of sensory evaluation and melting properties, in order to learn the differences of T. fuciformis ice cream under various stabilizer models, were evaluated and elucidated. Therefore, we obtained 300 mesh at 0.9% additive ratio of T. fuciformis powder, which is closest to the fresh fruit body/base ice cream. The enrichment of ice cream with T. fuciformis is to enhance the nutritional aspects and develop a functional food. Overall, the kinetic parameters of T. fuciformis ice cream melting can be provided as a reference for frozen dessert processing technology.
