Microencapsulation of linoleic acid with low- and high-molecular-weight components of soluble soybean polysaccharide and its oxidation process.

摘要: Soluble soybean polysaccharide (SSPS) was fractionated into its low- (LMW) and high-molecular-weight (HMW) components to test their antioxidative emulsifying properties. Linoleic acid emulsified with an aqueous solution of SSPS, HMW, a mixture LMW or HMW maltodextrin, maltodextrin alone. The emulsions prepared HWM the were stable. These spay-dried produce microcapsules. encapsulated linoleic oxidized at 37°C various levels relative humidity. stable oxidation, this stability increased as weight fraction in increased. also had high DPPH-radical scavenging activity. results indicate that played important role suppressing retarding oxidation SSPS. oxidative low humidity, but not intermediate
