Article Synopsis
- The study investigates how temperature affects the aggregation of demineralized arabinogalactan-proteins (AGPs) from Acacia seyal gum during dry incubation, showing that aggregation begins at temperatures as low as 25°C and accelerates as temperatures increase.
- The aggregation process involves self-assembly, with activation energy suggesting the involvement of chemical reactions tied to the dehydration of AGP surfaces.
- After about 1.66 days at 40°C, soluble aggregates form larger microparticles, revealing that cations in AGPs help protect against aggregation during heating, with demineralization increasing their reactivity.
Methylcellulose (MC) has a demonstrated capacity to reduce fat absorption, hypothetically through bile salt (BS) activity inhibition. We investigated MC cholesterol-lowering mechanism, and compared the influence of two BS, sodium taurocholate (NaTC) and sodium taurodeoxycholate (NaTDC), which differ slightly by their architecture and exhibit contrasting functions during lipolysis. BS/MC bulk interactions were investigated by rheology, and BS behaviour at the MC/water interface studied with surface pressure and ellipsometry measurements.
