High-Throughput Analysis of Sucrose Fatty Acid Esters by Supercritical Fluid Chromatography/Tandem Mass Spectrometry

Abstract

Supercritical uid chromatography (SFC) coupled with triple quadrupole mass spectrometry was applied to the pro ling of sucrose fatty acid esters (SEs). e SFC conditions (column and modi er gradient) were optimized for the e ective separation of SEs. In the column test, a silica gel reversed-phase column was selected. en, the method was used for the detailed characterization of commercial SEs and the successful analysis of SEs containing di erent fatty acids. e present method allowed for fast and high-resolution separation of monoesters to tetra-esters within a shorter time (15 min) as compared to the conventional high-performance liquid chromatography. e applicability of our method for the analysis of SEs was thus demonstrated.Please cite this article as: K.

Cellulose nanofiber‐based emulsion coatings with enhanced hydrophobicity and surface adhesion for preserving anthocyanins within thermally processed blueberries packed in aqueous media

“…As given in Table 1, the ST of CNF‐CS/SEFA‐1OA, CNF‐CS/XG‐1OA, and CNF‐CS/CMC‐1OA coating formulations were 28.56 ± 0.4, 32.98 ± 0.16, and 34.28 ± 0.35 mN/m, respectively, close to CST (28.41–37.52 dyne/cm) of blueberry surface regardless of washing and copigmentation treatment. However, when applying these coatings on blueberries, CNF‐based emulsion coating containing SEFA poorly interacted with the calcium alginate‐based second layer compared with other emulsion coatings, which might be because SEFA as a nonionic emulsifier composed of fatty acid was unable to interact with the hydrophilic second layer (Hori et al, 2014). However, the polysaccharides of XG and CMC could strongly interact with the second layer through hydrophilic interactions.…”
