Lupin meal presents great potential as an alternative plant-based source of proteins for human nutrition. In the present work, different conditions extraction and purification were evaluated production lupin protein isolates. The results showed that yield was comparable at acidic conventionally used alkaline pH (37% vs. 40-45%, respectively). Proteins extracted principally composed globulins. ionic strength negatively impacted extractability 2, whereas no significant differences observed...
Sinapine adsorption was studied on four weak cation exchanges at pHs ranging from 2 to 8. The best rate observed with C106 resin pH 4 (95.25%). kinetics followed a pseudo-second-order model while the isotherm data better fitted Langmuir model. ΔG°, ΔH°, and ΔS° values (−25.834 kJ·mol−1, −24.428 0.004 kJ·mol−1·K−1) revealed that process spontaneous exothermic. Acidified ethanol showed desorption (75.41%), virtually no (3.32%) or low (31.14%) sinapine 50% 0.1 M HCl solution, respectively. This...
The adsorption of a sunflower protein extract at two air–water and oil–water interfaces is investigated using tensiometry, dilational viscoelasticity, ellipsometry. For both interfaces, three step mechanism was evidenced thanks to master curve representations the data taken different aging times concentrations. At short times, diffusion limited proteins demonstrated. First, two-dimensional film formed with partition polypeptide chains in phases that depends strongly on nature hydrophobic...
Exploitation of plant proteins as an alternative to animal currently presents important challenge for food industries. In this contribution, total sunflower protein isolate from cold press meal was used a starting material the generation highly soluble and functional hydrolysates that could be in various formulations. To do this, rational complete approach controlled hydrolysis implemented using individual Alcalase Prolyve enzymes. The method stopping reaction also evaluated. influence...
Yeast extract (YE) is known to greatly enhance mammalian cell culture performances, but its undefined composition decreases process reliability. Accordingly, in the present study, nature of YE compounds involved improvement recombinant CHO growth and IgG production was investigated. First, benefits were verified, revealing that it increased maximal concentrations viable cells up 73 60%, respectively compared a reference culture. Then, analyses highlighted presence molecules such as amino...
