“…However, with a high concentration of NaOH (0.75 M), 42 was isolated in 13% yield, and 41 was isolated in 47% yield. The authors also reported the successful conversion of xylose (34) to xylitol, galactose (30) to dulcitol, and lactose (25) to a mixture of dulcitol and sorbitol, however, no information was given on the selectivity and the efficiency of these electrochemical reductions. From the range of parameters tested and by varying the reduced saccharides, the authors postulated that Pb and Hg were good cathode materials for poorly reducible compounds due to their high overpotential for hydrogen evolution.…”

The current climate awareness coupled with increased focus on renewable energy and biobased chemicals have led to an increased demand for such biomass derived products. Electrosynthesis is a relatively new approach that allows a shift from conventional fossil-based chemistry towards a new model of a real sustainable chemistry that allows to use the excess renewable electricity to convert biobased feedstock into base and commodity chemicals. The electrosynthesis approach is expected to increase the production efficiency and minimize negative health for the workers and environmental impact all along the value chain. In this review, we discuss the various electrosynthesis approaches that have been applied on carbohydrate biomass specifically to produce valuable chemicals. The studies on the electro-oxidation of saccharides have mostly targeted the oxidation of the primary alcohol groups to form the corresponding uronic acids, with Au or TEMPO as the active electrocatalysts. The investigations on electroreduction of saccharides focused on the reduction of the aldehyde groups to the corresponding alcohols, using a variety of metal electrodes. Both oxidation and reduction pathways are elaborated here with most recent examples. Further recommendations have been made about the research needs, choice of electrocatalyst and electrolyte as well as upscaling the technology.

“…The absences of oxidation peaks at potentials up to À0.4 V and higher to À0.1 V vs. SCE show the connection between the aldehyde group and the processes involved in these potential regions. Considering some other papers on the oxidation of some mono-and disaccharides [7][8][9][10][11], the reaction pathways for these processes can be tentatively presented. The first oxidation peak may be attributed to the oxidation of aldehyde (or hemiacetal) at carbon atom C1.…”

“…LBA was initially obtained by an electrolytic method using lactose (Isbell, 1933), concentrated alkaline reagents, graphite electrodes-to obtain lactose salts, such as calcium lactobionate, and catalysts (such as iodine and bromine), which could be carried along with the salt during its precipitation. Later on in the 90s, the use of gold and platinum electrodes resulted in higher acid yields (90% to 100%) (Druliolle, Kokoh, & Beden, 1994;Druliolle, Kokoh, Hahn, Lamy, & Beden, 1997). The oxidation process involved in electrolysis requires a large amount of energy, it is expensive and environmentally harmful due to the metal catalysts as well as the process residues (Alonso et al, 2013;Gupta et al, 2017;Miyamoto et al, 2000;Murakami et al, 2008).…”

Lactobionic acid (LBA) is a bionic acid naturally found in the “Caspian Sea yogurt” and chemically constituted of a gluconic acid bonded to a galactose. The compound is known for its numerous proven attributes as an antioxidant, chelator, and moisturizer agent. There is a growing interest of the academic community and industry research sectors in the application of LBA as a food ingredient. Thus, this review describes the current methods of LBA production, patents related, general applications and regulations, research statistics, future prospects, and an overview of the challenges faced by the food industry to incorporate the acid in their products. Studies associated to food application and human intake are scarce in the literature. To date, they account for only a small amount of all available research papers and patents on the subject, which is due to LBA prohibitions despite the approval of its salt (calcium lactobionate) and the lack of regulation in most countries. Further studies on the safety of consumption should be carried out in coming years in order to elucidate its toxicological aspects and to extend the technological possibilities of the food processing industry.
