Determination of 1,2/1,3-diglycerides in Sicilian extra-virgin olive oils by 1H-NMR over a one-year storage period

open access: yesNatural Product Research, 2017
This study is aimed to monitor by 1H NMR spectroscopy the effect of a 12-month storage period on the 1,2-diglycerides over 1,3-diglycerides ratio for five mono-cultivar ‘extra virgin olive oils’ (EVOO) (Arbequina, Arbosana, Cerasuola, Nocellara and FS17)

甘油二酯对可可脂类油脂结晶和巧克力起霜的影响研究进展Effects of diglycerides on crystallization of cocoa butter analogues and bloom of chocolates: a review

open access: yesZhongguo youzhi, 2023
可可脂类油脂富含对称型单不饱和甘油三酯,通过科学调控可可脂类油脂中的甘油二酯,可优化巧克力的调温工艺,控制其起霜行为。综述了可可脂类油脂中甘油二酯的含量与种类(包括脂肪酸饱和度、链长和位置分布),探讨其对油脂结晶行为的作用规律,进而分析其对巧克力抗霜性能的影响。在适宜含量下1,3-甘油二酯可促进油脂形成巧克力需要的Ⅴ型晶体结构,而1,2-甘油二酯则倾向于使油脂形成Ⅱ~Ⅳ型晶体结构,且作用程度受脂肪酸链长的影响。然而,高含量甘油二酯无法使油脂形成Ⅴ型晶体结构。当甘油二酯含量在3%~5%时 ...

Synthesis of diglycerides containing polyunsaturated fatty acids

open access: yesТонкие химические технологии, 2012
Synthetic approaches to obtain diglycerides containing polyunsaturated fatty acids at C(2 ) position of glycerol were developed. These compounds can be used to generate antitumor lipids and enzymatically triggered liposomes .

Monogalactosyl and digalactosyl diglycerides from heterotrophic, hetero-autotrophic, and photobiotic Euglena gracilis

open access: yesJournal of Lipid Research, 1966
The lipid of Euglena gracilis, dark-grown in a complete medium, contained 2% galactose. The lipid of Euglena gracilis, light-grown in either a complete or an inorganic medium, contained 13-14% galactose.
