On some mechanistic aspects of the electrochemical oxidation of lactose at platinum and gold electrodes in alkaline medium

Electro-oxidation of d-mannose on platinum, gold and nickel electrodes in aqueous medium

“…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.…”

Electrocatalytic oxidation of monosaccharides on gold electrode in alkaline medium: Structure–reactivity relationship

“…The important electro-reactivity of carbohydrates on gold electrode in alkaline medium, with hydrous oxides acting as catalyst, is well known [10][11][12][13][14][15]. But, according to our knowledge, there are very few contributions [16] concerning a systematic study with a large number of carbohydrates and derivatives in order to understand the effect of molecular structure on electrochemical behavior.…”

Lactobionic Acid as a Potential Food Ingredient: Recent Studies and Applications

“…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).…”
