Food industry is concentrating on development of novel functional foods fortified/enriched with lipophilic bioactives to improve health and well-being of consumers. beta-carotene (BC) and eugenol (EU) co-encapsulated flax seed oil (FSO) emulsions stabilized by octenyl succinic anhydride modified starches (OSA-MS) were spray dried to powders after the emulsification process. Microcapsules showed good dissolution behavior, high (approximate to 90%) microencapsulation efficiency and semi-spherical morphology observed by scanning electron microscopy. A 28 days storage test at 40 degrees C was carried out to evaluate the effect on physicochemical properties of microcapsules. Microcapsules encapsulated by lower Mw OSA-MS-1 presented higher oxidative stability, lower moisture contents and water activity during storage compared to high Mw OSA-MS-2. Incorporation of EU played its antioxidant role and further improved the oxidative stability as well as retention of core materials. Microcapsules of OSA-MS-1 containing FSO + BC + EU exhibited the maximum retention of BC (71%), EU (84%) and a-linolenic acid (92%). This study indicated a positive role of EU as antioxidant and low Mw OSA-starch as wall material for the encapsulation of lipophilic bioactives that could be used for the development of functional foods and beverages.
