Oxidation of linoleic acid encapsulated with soluble soybean polysaccharide by spray-drying.
Linoleic acid was encapsulated with a soluble soybean polysaccharide, gum arabic, or a mixture of both together with maltodextrin, and the oxidation process of the encapsulated acid was measured at 37 degrees C and at a relative humidity of 12%. The soybean polysaccharide was more effective for encapsulating the acid and suppressing the oxidation of the encapsulated acid than gum arabic. A mixture of the soybean polysaccharide and maltodextrin was also effective for this purpose when the weight fraction of the polysaccharide was equal to or greater than 0.75.
