Isolation of peanut protein aggregates using aqueous extraction processing combined with membrane separation

Sequential microfiltration and ultrafiltration was used for recovery proteins from aqueous phase. Recycling of permeate obtained from UF processing in AEP was primarily explored. Solubility, in vitro digestion and binding forces peanut protein aggregates(PPA) was investigated. Hydrophobic interaction was the majority force restrict dissolving of PPA and disulfide bonds took the second place.
