To increase the intestinal delivery of dietary β-carotene, there is a need to develop nanostructured food systems encapsulate this fat soluble bioactive. The aim study was evaluate bioacessibility and bioavailability across barrier β-carotene-enriched nanoemulsions stabilised with two emulsifiers (lecithin or sodium caseinate) by coupling an in vitro gastrointestinal digestion cell culture mode...

This study aimed to evaluate the effect of moderate electric field (MEF) treatment, as a non-thermal technology, on structure and techno-functionality sodium caseinate. Colloidal dispersions caseinate were subjected different MEF processing conditions (2.56 V cm−1 for 1 2 h, 38.46 5 20 s) their structural, physical, emulsifying film-forming characteristics assessed. The Fourier transform infrar...

Sodium caseinates prepared from bovine, sheep, goat, pig, buffalo or human milk were hydrolyzed by a partially purified proteinase of Lactobacillus helveticus PR4. Peptides in each hydrolysate were fractionated by reversed-phase fast-protein liquid chromatography. The fractions which showed the highest angiotensin I-converting-enzyme (ACE)-inhibitory or antibacterial activity were sequenced by ...

Systematic experimental study of the physico-chemical factors controlling the foaming and defoaming performance of several Pluronic nonionic block copolymers is performed in solutions of sodium caseinate. Dynamic light scattering measurements and microscopic observations confirm that a significant defoaming is observed above the cloud point of the nonionics, which is almost independent on the p...

15 Animals strongly regulate the amount of protein that they consume. The quantity of 16 individual essential amino acids (EAAs) obtained from dietary protein depends on the 17 protein source, but how much EAA proportions in diet affect nutrient balancing has been 18 rarely studied. Recent research using the Geometric Framework for nutrition has revealed 19 that forager honeybees who receive mu...
