Abstract: Inclusion of this study used complex wpc80 powder method for embedding hydrolysate, the impact of embedding wpc80 powder hydrolysate a variety of factors such as wall material selection, composite wall material ratio, heart wood and wall material proportion of total solids concentration, such as the time a heterogeneous system, the embedded product formulations, process parameters were optimized. The experimental results show that, in a wpc80 hydrolysate powder embedded in the process of selection of soybean lecithin, β-cyclodextrin as a wall material than used β-cyclodextrin, monoglyceride and other materials to build a better wall effect; wall material ratio (β-cyclodextrin / soybean lecithin) on the rate of embedded products significantly. Microcapsules in the appropriate scope of emulsion viscosity, increase the ratio of β-cyclodextrin, to increase the rate of embedding; heart wood and the ratio of wall material has a certain impact embedding rate, but high proportion of heart wood, embedding will lead to increased emulsion viscosity, emulsion stability reduced, embedding efficiency dropped, the total solids content will affect the spray-drying speed and the formation of vitreous wall material, thus affecting the efficiency of embedded. Different process conditions on the structure of microcapsules have enormous impact, affecting the quality of the products.
