“…Quantitative results showed that the PD contamination reduces the contents of glycerolipid (Figure h, decreased from 33638.3 ± 28.9 to 10454.2 ± 28.4 mg kg –1 ), phosphoglyceride (Figure i, decreased from 467.4 ± 8.2 to 56.6 ± 4.2 mg kg –1 ), and sphingolipids (Figure j, decreased from 11.4 ± 0.3 to 0.7 ± 0.2 mg kg –1 ) in milk, while it increases the concentrations of fatty acids (Figure a). Previous studies have proved that PD is an hygroscopic organic solvent, and the increase of its concentration would enhance the surface tension of aqueous solution . The strength of the oil–water interface facial mask was weakened by high interfacial tension, which is adverse to the stability of oil in an water emulsion .…”

“…Previous studies have proved that PD is an hygroscopic organic solvent, and the increase of its concentration would enhance the surface tension of aqueous solution. 20 The strength of the oil−water interface facial mask was weakened by high interfacial tension, which is adverse to the stability of oil in an water emulsion. 21 In addition, the hydrophobic interaction is an important factor to maintain the structure of milk micelles, and increasing studies proved that PD can effectively reduce the hydrophobic force of protein, which is harmful to the stability of milk systems.…”

The scandal of detecting the flavoring solvent propane-1,2-diol (PD) in milk has brought a crisis to the trust of consumers in the dairy industry, while its deposition and transformation are still indistinct. Pseudo-targeted lipidomics revealed that PD accelerated the degradation of glycerolipid (33,638.3 ± 28.9 to 104,54.2 ± 28.4 mg kg −1 ), phosphoglyceride (467.4 ± 8.2 to 56.6 ± 4.2 mg kg −1 ), and sphingolipids (11.4 ± 0.3 to 0.7 ± 0.2 mg kg −1 ), which extremely decreased the milk quality. Recoveries and relative standard deviations (RSDs) of the established method were 85.0−109.9 and 0.1−14.9%, respectively, indicating that the approach was credible. Protein−lipid interactions demonstrated that 10 proteins originating from fat globules were upregulated significantly and the activities of 7 enzymes related to lipid degradation were improved. Diacylglycerol cholinephosphotransferase was the only enzyme with decreased activity, and the molecular docking results indicated that PD adjusted its activity through regulating the conformation of the active center and weakening the hydrogen bond force between the enzyme and substrate. This study firstly revealed the mechanism of deposition and transformation of PD in milk, which contributed to the knowledge on the milk quality control and provided key indicators to evaluate the adverse risks of PD in dairy products.

“…Current research should most likely focus on the synthesis of new catalysts in order to improve the selectivity allowing industrial implementation of this technology. Although sorbitol is the most expensive raw material, it did not preclude ADM to commercialize in 2010 the process based on glycerol and sorbitol . Therefore, focusing only on raw material market prices and energy consumption may not be sufficient to assess the economic potential of a given process without taking into account an in-depth economic analysis of a particular company and its local conditions.…”

The production of 1,2-propanediol is a significant challenge for the chemical industry due to the increasing demand for this versatile product and the pro-ecological regulatory actions. The traditional method of producing this compound through the hydrolysis of petroleum-derived 1,2-epoxypropane (propylene oxide) is energy intensive, and sustainable routes based on renewable raw materials are becoming more attractive. This perspective presents the current state of scientific and patent literature on the production of 1,2-propanediol and the implementation of new technologies by leading companies. This perspective also discusses alternative pathways, including glycerol hydrogenolysis and biotechnological methods, highlighting their potential to reduce energy consumption and lower the carbon footprint of the process. The focus is on modern methods, including chromium-free catalytic systems for glycerol hydrogenolysis, in situ hydrogen generation, and multifunctional catalysts for saccharides hydrolysis and hydrogenolysis. Biobased 1,2-propanediol produced from renewable alternative raw materials has great potential to replace traditional petroleum-derived 1,2-propanediol with substantial environmental and economic benefits.

“…Among the green fuels and chemicals produced from crude glycerol, propylene glycol (1,2-propanediol) is the subject of immense interest due to its wide range of industrial applications. 9 Propylene glycol is a ubiquitous chemical that can be used as a non-toxic antifreeze, moisturizer, surfactant, and preservative. 10 Commercially, propylene glycol is often produced from the hydrolysis of petroleum-derived propylene oxide, a process that produces significant greenhouse gases.…”
