Physicochemical Studies on the Interaction between Sodium Dodecyl Sulfate and Methylene Blue in Methanol-Water Mixed Solvent Media

Journal of Chemistry, 2020
The surface activity and the process of micellization of sodium dodecyl sulfate (SDS) with methylene blue (MB) in a methanol-water mixed solvent system were investigated by tensiometry and conductometry at 298.15 K.

Whey- and Soy Protein Isolates Added to a Carrot-Tomato Juice Alter Carotenoid Bioavailability in Healthy Adults

Antioxidants, 2021
Recent findings suggested that proteins can differentially affect carotenoid bioaccessibility during gastro-intestinal digestion. In this crossover, randomized human trial, we aimed to confirm that proteins, specifically whey- and soy-protein isolates ...

Experimental investigation of surface activity, micellization behaviour, and enhanced oil recovery performance of saponin‐based green surfactants

The Canadian Journal of Chemical Engineering, EarlyView.
This graphical abstract illustrates the steps carried out in the laboratory study, including saponin modification and characterization, surface tension, interfacial tension, contact angle, adsorption, and surfactant injection tests. Abstract In this study, three forms of saponin surfactants extracted from the Camellia sinensis plant (CS1, CS2, and CS3)

Impact of Protein-Enriched Plant Food Items on the Bioaccessibility and Cellular Uptake of Carotenoids

Antioxidants, 2021
Carotenoids are lipophilic pigments which have been associated with a number of health benefits, partly related to antioxidant effects. However, due to their poor solubility during digestion, carotenoid bioavailability is low and variable. In this study,

Study of Micellar Behavior of Crown Ether and Tetraethylammonium Bromide in Aqueous Media

E-Journal of Chemistry, 2010
Conductivity measurements have been carried out to study the micellar behavior of tetraethylammonium bromide in presence of 15-crown-5 in aqueous media. The measurements were carried out at 298.15 K as a function of surfactant concentration with varying ...

Critical self-association of bile lipids studied by infrared spectroscopy and viscometry.

Journal of Lipid Research, 1990
Fourier transform infrared (FTIR)-attenuated total reflection (ATR) spectroscopy and viscometry were applied to study the micellization of two bile lipids, sodium taurochenodeoxycholate (NaTCDC) and sodium glycocholate (NaGC), in aqueous solutions.

Progress in vegetable proteins isolation techniques: A review [PDF]

Food and Feed Research, 2017
Novel vegetable proteins, like those extracted from abundant raw materials (grass) or agri-food by-products and waste streams (oilseed meals), are expected to be used as replacers for animal-derived proteins, due to higher production efficiency, reduced ...

Study on the Effects of Biologically Active Amino Acids on the Micellization of Anionic Surfactant Sodium Dodecyl Sulfate (SDS) at Different Temperatures

Chemistry, 2022
The micellar properties of the anionic surfactant, sodium dodecyl sulfate (SDS) are modified by the biologically active amino acids. Amino acids (AAs) have experienced a variety of interactions and are proposed to influence SDS micelles due to their ...
