The stability of spray-dried microencapsulated β-carotene in the mixture of gum Arabic, OSA type modified starch and maltodextrin

The study analyzed effects of using a mixtures of three carriers: gum Arabic, OSA type modified starch and maltodextrin, used in different ratios on the properties of ?-carotene microencapsulated by spray drying. ?-carotene emulsions were prepared using high-pressure two-stage homogenization. Characteristics of emulsion properties and the features of the microcapsules. To determine the relation between the studied characteristics PCA were used.It has been shown that the use of mixed media in equal proportions increases less the retention of the pigment during the storage of microcapsules than mixtures with different carriers ratios. The matrix which was the most effective in protecting the core, was made of a mixture of modified starch, gum Arabic and maltodextrin in the ratio of 1:3:2. It was also found that the larger content of gum Arabic in the mixture of carriers improved the protection against the degradation of ?-carotene than increasing content of OSA type modified starch.
