The grape juice pre-concentrated by reverse osmosis was freeze-drying with and without the hydrocolloids; however, under the second condition, the powder was not obtained. The grape juice drying process by spray-drier was difficult due to its high sugar content. Valduga et al. (2008) during anthocyanins spray-drying microencapsulation observed losses of the core material because a large part of was retained in the walls of the drying chamber, which showed that the freeze-drying process with the addition of hydrocolloids was an interesting viable alternative. The humidity of the powder remained lower than 5% and there was a significant increasing of 86% in the total solids content compared to the whole grape juice (Table 1). The water activity decreased from 0.98 to 0.43, increasing the product shelf life significantly, reducing powder contamination by the microorganisms and increasing their applicability as ingredients in food industry
