Lipase‐mediated plant oil hydrolysis—Toward a quantitative glycerol recovery for the synthesis of pure allyl alcohol and acrylonitrile

open access: yesEuropean Journal of Lipid Science and Technology, Volume 125, Issue 9, September 2023., 2023
Selection of a suitable lipase provides for quantitative hydrolysis of triacylglycerides without unwanted coproducts. Optimization of the reaction in solely water as sole reaction medium allows for cost efficient conversion of plant oils and and recovery of a highly pure glycerol product as precursor for acrylonitrile synthesis as well as free fatty ...

Toward sustainable production of value‐added bioenergy and industrial oils in oilseed and biomass feedstocks

open access: yesGCB Bioenergy, Volume 13, Issue 10, Page 1610-1623, October 2021., 2021
Triacylglycerols (TAGs), the principal component of plant vegetable oils, are energy‐dense storage forms of fatty acids that can function as feedstocks for biofuels and bioproducts. The value of TAGs for these non‐food applications can be enhanced by the introduction of unusual fatty acids with structural modifications that expand vegetable oil ...

Chlorinated Phospholipids and Fatty Acids: (Patho)physiological Relevance, Potential Toxicity, and Analysis of Lipid Chlorohydrins

open access: yesOxidative Medicine and Cellular Longevity, Volume 2016, Issue 1, 2016., 2016
Chlorinated phospholipids are formed by the reaction of hypochlorous acid (HOCl), generated by the enzyme myeloperoxidase under inflammatory conditions, and the unsaturated fatty acyl residues or the head group. In the first case the generated chlorohydrins are both proinflammatory and cytotoxic, thus having a significant impact on the structures of ...

Enzymatic biosynthesis of ricinoleic acid estolides

open access: yesBiochemical Engineering Journal, 2005
Candida rugosa lipase has been shown to have sufficient activity to catalyse the enzymatic synthesis of ricinoleic acid estolides in a batch reactor. The water requirements of the reactor change during the reaction: at the beginning of the process a minimum amount of water is necessary but, later, the reaction mixture must be dried out to obtain an ...

The Food Additive Polyglycerol Polyricinoleate (E‐476): Structure, Applications, and Production Methods

open access: yesInternational Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
The food additive named polyglycerol polyricinoleate (PGPR) and identified with the code E‐476 (PGPR) is used as emulsifier in tin‐greasing emulsions for the baking trade and for the production of low‐fat spreads. However, the main application of PGPR is in the chocolate industry, where, besides its action as an emulsifier, it also has important ...

Production of Chemoenzymatic Catalyzed Monoepoxide Biolubricant: Optimization and Physicochemical Characteristics

open access: yesBioMed Research International, Volume 2012, Issue 1, 2012., 2012
Linoleic acid (LA) is converted to per‐carboxylic acid catalyzed by an immobilized lipase from Candida antarctica (Novozym 435). This per‐carboxylic acid is only intermediate and epoxidized itself in good yields and almost without consecutive reactions.
