Metal cation‐induced conformational changes of soybean protein isolate/soybean soluble polysaccharide and their effects on high‐internal‐phase emulsion properties

Metal ions commonly inevitably appear in food products and have adverse effects on high-internal-phase emulsions (HIPEs) foods, but conformational conversion of soybean protein isolate (SPI)/soybean soluble polysaccharide (SSPS) on the interface layer of HIPEs influenced by different metal ions has rarely been reported.
