This paper discusses our attempt to generate substitutes for human breast milk fat through the interesterification of mixtures composed of lard and hemp (Cannabis sativa) seed oil. The interesterification was run at 60 °C for 2, 4, and 6 h in the presence of Lipozyme RM IM preparation containing a lipase specific for the cleavage of sn-1,3 ester bonds in triacylglycerol molecules. The interesterification products were analyzed regarding their fatty acid composition and distribution in triacylglycerol molecules. In order to assess the quality of the generated substitutes, in the interesterification products the following were determined: acid value, peroxide number, and oxidative stability. The collected data were statistically processed using Tukey’s test. Following the interesterification, the fats revealed an elevated percentage of free fatty acids and primary oxidation products and reduced oxidative stability compared to those of lard. The last of the above-mentioned phenomena could have been due to the incorporation of polyenic fatty acids into the external positions of triacyclglycerols of lard. The interesterification of lard and hemp seed oil allows scientists to acquire substitutes rich in essential fatty acids and similar to human breast milk fat with respect to the distribution of fatty acids in triacylglycerol molecules.

The modern dewaxing process using endogenous wax ester hydrolyses (wax desynthetase) activation in optimal reaction conditions provides an efficient, specific and targeted affinity destructuration process orientated towards the wax substrate in order to develop the depparafinage effect. The lipase W/O interfacial activation was studied in the lipolyse and interesterification process but the endogenous O/S dewaesterase activation was until now non-investigated. The isoparaffins structures formation improves the dewaxing yield at 90.7% reported on the miscella crude oil with 270 ppm waxes content with an almost double-cold dewaxed oil stability. The present modern dewaxing technology eliminates the low-efficiency cold/low temperature crystallisation and all the negative effects given by the solvent oil recovery from the kieselgur pomace, cooling agent producing and separation by filtration/centrifugation process.

Zero-trans edible fats attractive to be used for shortenings or margarines were designed solely from rice bran oil (RBO). For this purpose, RBO was fully hydrogenated, blended with the original oil at different percentages, and finally, blends were interesterified by an enzyme-catalyzed process. The interesterification process reduced the concentration of trisaturated and triunsaturated triglycerides and increased the concentration of medium saturation degree molecules, thus increasing their compatibility and causing the moderation of the melting point, as compared with blends. Conversely to blends, products showed a high tendency to crystallize under the β’ polymorph, which is the preferred one for products destined for many edible applications. Results demonstrated that the proper combination of different technologies (total hydrogenation, blending and interesterification) is a versatile and useful technology for designing zero-trans fats from RBO, attractive for the confection of shortenings or margarines for different applications depending on the proportion of each component in the starting blend. This strategy offers an attractive alternative for the diversification of RBO utilization, a valuable vegetable oil still underexploited, providing attractive fats useful for structuring different type of foods.

Sodium silicate as heterogeneous base catalysts is more environmentally friendly and easily separated by filtration. The objective of this research was to evaluate the activated sodium silicate as catalyst for synthesis of monoacylglycerol (MAG) and diacylglycerol (DAG)-rich structured lipids (SLs) from a palm olein-stearin blend. Sodium silicate was activated and functional group was characterized. Reaction was performed using 5% catalyst (w/w) at various reaction temperature (70–120 °C) for 3 h in a batch stirred tank reactor. Physical properties of SLs, such as melting point, slip melting point, and hardness of SLs were determined. Reaction kinetics were also evaluated. The results show that Si−O bending was reduced and shifted to a Si−O−Na and Si−O−Si functional groups after sodium silicate activation. Temperature had a significant effect on SLs composition at higher than 90 °C. An increase in temperature produced more MAG, resulting in better product physical properties. The best reaction condition was at 110 °C. Rate constants and the Arrhenius equation were also obtained for each reaction step. In summary, the activated sodium silicate catalyzed glycerolysis-interesterification reaction, which produced MAG and DAG at temperature higher than 90 °C. Therefore, the physical properties of SLs were improved. Copyright © 2022 by Authors, Published by BCREC Group.

Biodiesel production through chemical interesterification of triglycerides requires an excess of methyl acetate that must be recovered once the reaction is finished and the catalyst is neutralized. The present study concerns with the purification of methyl acetate by pervaporation. PERVAP 2201 was chosen as pervaporation membrane due to its high hydrophilic character that makes it suitable for the elimination of water in methyl acetate. Runs were started from concentrations in the feed of 2–8 wt.% of water and working temperatures close to the boiling point of methyl acetate (50, 60, and 70 °C), to get the main design parameters, i.e., permeate flux and selectivity. High temperature favored the permeate flux without compromising the selectivity. However, the flux declines significantly when water contained in the feed is below 2 wt.%. This implies that pervaporation should be used, only to decrease the water content to a value lower than in the azeotrope (2.3% by weight). A solution-diffusion model relating the flux of the permeating compound with the activity of the compound in the feed and the operating temperature has been proposed. The model obtained can be used in the design of the pervaporation stage, thus allowing to know the permeate flux for the different operating conditions.

Due to the awareness of adverse effects of conventional fuels on environment and on a frequent rise in the crude oil price, the need for a sustainable and environment-friendly alternate source of energy has gained importance. Recently, options have been analysed to replace the triglyceride transesterification process, which is generally used in biodiesel production, by the process where raw glycerol is not generated, whereas triacylglycerides obtained instead glycerol can be directly used as fuel for a diesel engine in a mixture with fatty acid esters. In the present work, interesterification of rapeseed oil to biodiesel was carried out with methyl formate and using lipase as a catalyst. The research was carried out at the Laboratory of Chemical and Biochemical Research for Environmental Technology of Aleksandras Stulginskis University. First, the most effective biocatalyst suitable for the process was selected. 14 different lipases were studied. The samples obtained after the synthesis were analysed by the thin-layer and gas chromatography. Process experiments were performed using a methyl formate to oil molar ratio of 6:1 to 40:1, a lipase amount of 5 to 17% (mass of oil) and synthesis duration of 3 to 48 h. The highest yield of fatty acid methyl esters (FAME) was obtained using Lipozyme RM IM as a catalyst and its optimal amount was 13%. The optimal temperature was found to be 20°C and the duration of interesterification 42 h. The optimal molar ratio of methyl formate to oil was determined to be 32:1. Under the obtained conditions the transesterification degree was 60.68 ± 0.95%.
