“…The tocopherol analysis, used 292–298 nm UV spectrometer as the detector, while the wavelength of DAG and MAG occurred at 210 nm (Turkan & Kalay, 2006). In addition, monostearate has a wavelength of 208 nm (Kavadia et al., 2017). Possibly, this could explain interference detected during tocopherol analysis after deodorisation.…”

Retention of micronutrients in high oleic palm oil (HOPO) was evaluated by comparing two methods; standard refining (260 °C) and modified refining (160, 180, 200 °C). Tocopherol analysis showed that αtocopherol loss during standard refining was relatively low for both refined bleached and deodorised (RBD) PO control (10%) and RBDHOPO (2%). On the contrary, the carotene loss for both RBDPO control and RBDHOPO in standard refining methods was 99% (1.9 and 5.9 ppm, detected). Modified refining temperatures, can maintain up to 99% more carotenes than standard refining. Applying modified refining to RBDHOPO retains ∼ 78%-83% more carotene than regular RBDPO. This examination shows, suitably processed RBDHOPO has the capability for producing a red palm oil (RPO), enriched with carotenoid for provitamin A function.

“…Odaneth and colleagues previously showed that stearoyl-glycerol synthesis was successfully achieved by performing an esterification using glycerol and stearic acid [25]. Herein, we adapted this strategy that was key for the synthesis of 1-LG-d 5 , the latter being commercially unavailable.…”

“…For the synthesis of 1-LG-d 5 , we followed a previously documented strategy involving the enzyme Novozym 435 [25]. In brief, LA and glycerol-d 5 (0.2 and 0.6 mmol, respectively) were dissolved in tert-butanol (1.2 mL).…”

The endocannabinoids 2-arachidonoyl-glycerol and N-arachidonoyl-ethanolamine are lipids regulating many physiological processes, notably inflammation. Endocannabinoid hydrolysis inhibitors are now being investigated as potential anti-inflammatory agents. In addition to 2-arachidonoyl-glycerol and N-arachidonoyl-ethanolamine, the endocannabinoidome also includes other monoacylglycerols and N-acyl-ethanolamines such as 1-linoleoyl-glycerol (1-LG) and N-linoleoyl-ethanolamine (LEA). By increasing monoacylglycerols and/or N-acyl-ethanolamine levels, endocannabinoid hydrolysis inhibitors will likely increase the levels of their metabolites. Herein, we investigated whether 1-LG and LEA were substrates for the 15-lipoxygenase pathway, given that both possess a 1Z,4Z-pentadiene motif, near their omega end. We thus assessed how human eosinophils and neutrophils biosynthesized the 15-lipoxygenase metabolites of 1-LG and LEA. Linoleic acid (LA), a well-documented substrate of 15-lipoxygenases, was used as positive control. N-13-hydroxy-octodecadienoyl-ethanolamine (13-HODE-EA) and 13-hydroxy-octodecadienoyl-glycerol (13-HODE-G), the 15-lipoxygenase metabolites of LEA and 1-LG, were synthesized using Novozym 435 and soybean lipoxygenase. Eosinophils, which express the 15-lipoxygenase-1, metabolized LA, 1-LG, and LEA into their 13-hydroxy derivatives. This was almost complete after five minutes. Substrate preference of eosinophils was LA > LEA > 1-LG in presence of 13-HODE-G hydrolysis with methyl-arachidonoyl-fluorophosphonate. Human neutrophils also metabolized LA, 1-LG, and LEA into their 13-hydroxy derivatives. This was maximal after 15–30 s. Substrate preference was LA ≫ 1-LG > LEA. Importantly, 13-HODE-G was found in humans and mouse tissue samples. In conclusion, our data show that human eosinophils and neutrophils metabolize 1-LG and LEA into the novel endogenous 15-lipoxygenase metabolites 13-HODE-G and 13-HODE-EA. The full biological importance of 13-HODE-G and 13-HODE-EA remains to be explored.

“…The chemical method of MGS synthesis produce a mixture of acylglycerols (DGS, and tryacylglycerols) and make the synthesis of MG from a single fatty acid type impossible by this route [5]. In addition, because glycerol and fatty acids react spontaneously at 110 °C and the reaction proceeds significantly at higher temperatures, it is difficult to prevent the formation of DGS and triglycerides during direct esterification at higher temperatures [6].…”

The Potential of Halal Anti-Foam Production from Vegetable Oil Derivatives: a Review

The foam that occurs in the process can cause problems with the effectiveness of the process or the quality of the final product. The economic consequences of uncontrolled foaming can be very significant and cause serious losses and require expensive operating changes. Foaming problems can be just as expensive as treating other types of problems, such as corrosion, fouling, or emulsion. Indonesia is known as the largest producer of palm oil, so it has the potential as a producer of downstream palm oil derivative products, especially halal anti-foam with renewable raw materials. In the food industry, only calcium alginate, monoglycerides (MGS), and diglycerides (DGS) are permitted. The use of renewable raw materials in industrial processes is one of the steps to realizing the Sustainable Development Goals, especially the second goal, which is zero hunger in 2030. The details of the mechanism of action and the use of anti-foam in the food, medicine, cosmetics, textile, oil refining, petrochemical, paint, and pulp paper industries were discussed. Furthermore, the potential use of palm oil as raw material for halal anti-foaming is very prospective, considering that there are not many palm oil-based anti-foam products applied in various food industries.
