An effective evaluation model was established to digitize the quality of cocoa butter equivalents (CBEs) based on determinations of total and sn-2 fatty acid compositions and triacylglycerol (TAG) profiles and the "deducting score" principle. Similarity scores for selected fats and oils
Mango processing generates high amounts of unexploited kernels. Lipid profiles and thermal behaviour of kernel fats from seven Mangifera indica L. cultivars originating from Latin America and Thailand were characterised. Total lipid contents ranged between 5.4 and 11.9%. Detailed GC-FID, GC-MS, and
The main constituents of plant oils are complex mixtures of TGs differing in acyl chain lengths, number and positions of double bonds, and regioisomerism. A non-aqueous reversed-phase HPLC method with acetonitrile-2-propanol gradient and 30 + 15 cm NovaPak C18 columns makes possible an unambiguous
Medium chain (MC) and behenic fatty acids were incorporated into kokum, sal and mango fats using 1,3-specific lipase catalysed acidolysis. The incorporation of fatty acids increased with increase in concentration of fatty acids and duration of reaction. The order of incorporation of fatty acids was
Irvingia gabonensis, also known as 'bush mango', is a multipurpose fruit tree, native to tropical Africa. It is a priority indigenous fruit tree in western and central Africa since its wood is used for making utensils and fruits are mostly used as food and medicine. The objective of this work
Assignment of (13)C nuclear magnetic resonance (NMR) spectra of major fatty acid components of South African produced vegetable oils was attempted using a method in which the vegetable oil was spiked with a standard triacylglycerol. This proved to be inadequate and therefore a new rapid and
To gain more insight into the molecular mechanisms of Colletotrichum gloeosporioides pathogenesis, restriction enzyme-mediated integration (REMI) mutagenesis identified the mutants of C. gloeosporioides impaired in pathogenicity. Transformants screened for defects in pathogenicity using detached
The temperate climax tree species Fagus sylvatica and the floodplain tree species Populus × canescens possess contrasting phosphorus (P) nutrition strategies. While F. sylvatica has been documented to display P storage and mobilization (Netzer et al., 2017), this was not observed for Populus ×
Cocoa butter equivalents (CBEs) are produced from vegetable fats by blending palm mid fraction (PMF) and tropical butters coming from shea, mango kernel or kokum fat. In this regard, high oleic-high stearic (HOHS) sunflower hard stearins from solvent fractionation can be used in CBE production since
Mango kernel fat (MKF) has been reported to have high functional and nutritional potential. However, its application in food industry has not been fully explored or developed. In this review, the chemical compositions, physical properties and potential health benefits of MKF are described. MKF is a
High-purity isohexane containing 88.12% 2-methylpentane, which has a higher polarity than industrial hexane, was selected to selectively fractionate mango kernel fat to produce 1,3-distearoyl-2-oleoyl-glycerol (SOS)-rich fat. The three-stage fractionation process was optimized by considering the
The lipid composition of whole leaves and isolated plastoglobul of beech (Fagus sylvatica) has been studied during four natural autumnal senescence stages. Chlorophylls, glycolipids, and phospholipids were extensively degraded in leaves. About 20% of the glycolipids found in leaves during summer,
