Foaming Novatein thermoplastic protein
… This work aimed to develop an appropriate foaming method and the principles governing it. Foaming was initially investigated through extrusion which was unsuccessful due to the low speed and pressure drop. However, by using high speed and pressure, Novatein was successfully foamed in an …

Foaming properties of whey protein isolate and [lambda]-carrageenan mixed systems
… with improved functional properties. Studies on foaming properties of whey protein isolate (WPI) with polysaccharide mostly focused on the effects of polysaccharide on native WPI or heated WPI, while little has been done on heated WPI-polysaccharide soluble complex. The objective of our research …
