An ethanol treatment (10% volume/volume) inhibited the yellowing of fresh-cut yam during storage. The ethanol treatment also prevented bisdemethoxycurcumin formation, and reduced the contents of metabolites in fresh-cut yam during storage at 25°C. Ethanol treatment also inhibited the activities of key enzymes in the phenylpropanoid pathway, including phenylalanine ammonia lyase (PAL), cinnamic acid-4-hydroxylase (C4H), and 4-coumarate-CoA ligase (4CL), and decreased the transcription level expressions of PAL, C4H, and 4CL compared to the control. The expressions of diketide-CoA synthase, curcumin synthase 3, and curcumin synthase were also reduced by ethanol treatment compared to the control, in agreement with the absence of bisdemethoxycurcumin in fresh-cut yam treated with ethanol. These findings suggest that ethanol can be used to attenuate the yellowing of fresh-cut yam stored at 25°C, which may be related to ethanol inhibition of the phenylpropanoid pathway and bisdemethoxycurcumin biosynthesis. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Application of 33171-05-0).
Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
