Abstract:

Spray-drying method was used to prepare a type of stable arachidonic acid (AA) product, AA microcapsules, which could slow down the process of auto-oxidation effectively, and the properties of AA microcapsules were tested and evaluated. The AA microcapsules prepared using maltodextrin as the wall material and complex emulsifier L had the best stability. No layer phenomenon and particles being linked to the wall were found in reconstituted emulsions. The embedding rate reached 93.48%.

Key words: arachidonic acid (AA), spray-drying, emulsifier
