AI Technical Summary
Existing membrane filtration technologies are inefficient and costly for separating native proteins from phenolic and/or glycoalkaloid compounds in potato fruit juice due to adherence and fouling issues, leading to low selectivity and membrane fouling.
A method involving diafiltration with solvents of increased ionic strength to enhance membrane permeability and flux, followed by multiple cross-flow membrane filtration steps to separate and recycle salts, phenolic compounds, and glycoalkaloids, maintaining the integrity of native proteins.
Achieves high purity and quality separation of native proteins and phenolic/glycoalkaloid compounds at industrial scale, reducing fouling and cost by recycling salts and solvents, and improving membrane efficiency.
