Relationship between Functional Properties and Aggregation Changes of Whey Protein Induced by High Pressure Microfluidization
79
TL;DR: It was indicated that HPM induced 2 kinds of aggregation changes on WPC: deaggregation and reaggregation, which resulted in the changes of functional properties of WPC modified by HPM, which showed significant modifications in the solubility and foaming properties with increasing pressure.

Abstract: Aggregation changes of whey protein induced by high-pressure microfluidization (HPM) treatment have been investigated in relation with their functional properties. Whey protein was treated with HPM under pressure from 40 to 160 MPa. Functional properties (solubility, foaming, and emulsifying properties) of whey protein concentrate (WPC) ultrafiltered from fluid whey were evaluated. The results showed significant modifications in the solubility (30% to 59%) and foaming properties (20% to 65%) of WPC with increasing pressure. However, emulsifying property of WPC treated at different pressures was significantly worse than untreated sample. To better understand the mechanism of the modification by HPM, the HPM-induced aggregation changes were examined using particle size distribution, scanning electron microscopy, and hydrophobicity. It was indicated that HPM induced 2 kinds of aggregation changes on WPC: deaggregation and reaggregation of WPC, which resulted in the changes of functional properties of WPC modified by HPM.

Food Processing by High Hydrostatic Pressure
TL;DR: The use of high hydrostatic pressures (HHP) for food processing is finding increased application within the food industry because it does not use heat, sensory, and nutritional attributes of the product remain virtually unaffected, thus yielding products with better quality than those processed traditional methods.
