“…Glycolic acid is used in the textile industry as a dyeing and tanning agent, in food processing as a flavoring agent and as a preservative, and in the pharmaceutical industry as a skin care agent [21]. It is also used together with lactic acid, another high value glycerol oxidation product, to produce a co-polymer (poly (lactic-co-glycolic acid), PLGA) for medical application in drug delivery [22]. Among these compounds, tartronic acid is a high value-added chemical with high biological activity used in the treatment of metabolic disorders, liver diseases, and osteoporosis.…”

Glycerol Oxidation over Supported Gold Catalysts: The Combined Effect of Au Particle Size and Basicity of Support

et al. 2020

Gold nanoparticles supported on various oxides (CeO2, CeO2/TiO2, MgO, MgO/TiO2, La2O3, La2O3/TiO2) (with 4 wt.% Au loading) were investigated in the liquid (aqueous) phase oxidation of glycerol by molecular oxygen under mild conditions, in the presence of alkaline earth (CaO, SrO and MgO) or alkaline (NaOH) bases. Full conversion and selectivity between 38 and 68% to sodium glycerate were observed on different Au supported catalysts (Au/MgO/TiO2, Au/La2O3/TiO2, Au/CeO2 and Au/CeO2/TiO2). The combined effect of Au particle size and basicity of the support was suggested as the determining factor of the activity. Agglomeration of gold nanoparticles, found after the reaction, led to the deactivation of the catalysts, which prevents the further oxidation of sodium glycerate into sodium tartronate. Promising results were obtained with the use of alkaline earth bases (CaO, SrO, MgO), leading to the formation of free carboxylic acids instead of salts, which are formed in the presence of the more usual base, NaOH.

“…Ion-induced gelation also alters the electrostatic interaction between gelator molecules, as demonstrated by the classic example of Ca 2+ -induced gelation of sodium alginate (Cao & Mezzenga, 2020). Other multivalent ions used include magnesium and zinc (Santiago et al, 2017).…”

“…Two main sources of hydrogelators are polysaccharides and proteins (Banerjee & Bhattacharya, 2012). The gelators are sourced from plants, animals, and bacteria, which provide a wide range of gelators with different physicochemical properties (Santiago et al, 2017). For polysaccharide based hydrogels, the hydrogelator is typically dispersed into an aqueous system and heated until the gelling temperature (heat-set) or heated and then cooled (cold-set) to form a gel (Banerjee & Bhattacharya, 2012).…”

There is a growing market for healthy food products worldwide due to increasing consumer awareness on the impact of diet on health (Anderson, 2020;Sloan, 2020). In particular, the coronavirus pandemic has heightened consumers' demand for healthboosting products as a means to improve their immune system (Lempert, 2020). Many government agencies attribute poor health to poor diet, such as those high in fat, sugar, and salt, and, hence, provide dietary guidelines to encourage healthier eating habits (Gonzalez Fischer & Garnett, 2016). Most of these dietary guidelines agree that limiting intake of saturated fats and sugars can lead to long term good health and prevent diet-related illnesses (Gonzalez Fischer & Garnett, 2016). For example, the 2020-2025 edition of the Dietary Guidelines for Americans (Dietary Guidelines for Americans 2020-2025, 2020) encourage Americans to limit calories from saturated fat to under 10% of their total calories. Furthermore, the guidelines advocate consumption of unsaturated fats over saturated fats to reduce the risk of cardiovascular disease.
