摘要

The purpose of the present work was to study the effect of inlet temperature (160–180°C), feed rate (0.08–0.13?ml/s), concentration of gum Arabic (35–45%), aonla extract (6–8%), and basil extract (6–8%) on the product properties (bulk density, hygroscopicity, total phenolic content (TPC), antioxidant activity (AOA), and vitamin C content) of spray-dried nutritionally rich honey powder using response surface methodology . Higher inlet air temperatures led to lower bulk density and hygroscopicity, whereas addition of aonla and basil extracts led to higher TPC, AOA, and vitamin C content which were encapsulated by gum Arabic . Statistical analysis showed that independent variables significantly affected all the responses (p ??0.0001). Perturbation and 3D surface plots were drawn for each of the responses from the mathematical models. Second-order polynomial models with high R ~(2) (0.97–0.99) values were constructed for each powder physicochemical properties namely bulk density, hygroscopicity, TPC, AOA, and vitamin C content. Desirable nutritionally rich honey powder was obtained at inlet temperature of 170°C, 0.11?ml/s feed rate, 45% gum Arabic , 8% aonla extract, and 6% basil extract.
