Physical and antimicrobial characteristics of thyme oil emulsified with soluble soybean polysaccharide

There is a great need of essential oil emulsions as antimicrobial delivery systems to enhance microbiological safety of food products. In the present study, thyme oil was emulsified by soluble soybean polysaccharide (SSPS) at different SSPS-to-oil mass ratios (SORs) and physical and antimicrobial properties of emulsions were characterized. Particle dimension generally decreased with an increase in SOR and reached a constant at a SOR ≥5. For...
