“…Comparatively, canola oil contains 92% unsaturated fatty acids, including oleic acid, within its fatty acid profile. 20 Additional experiments evaluated the performance of TBD in various unrefined oil feedstocks using both methanol and DMC as methylating agents. All three oils could be described as black, tarry liquids similar to that of crude petroleum (Figure 1).…”

Conversion of High Free Fatty Acid Lipid Feedstocks to Biofuel Using Triazabicyclodecene Catalyst (Homogeneous and Heterogeneous)

et al. 2019

Traditional biodiesel is produced from feedstocks such as vegetable oils and animal fats by converting the triglycerides with methanol in the presence of a homogeneous catalyst to produce fatty acid methyl esters (FAMEs). However, drawbacks of this process include an undesired glycerol byproduct and post-reaction processing that result in increased production costs. In this study, unrefined corn oil and waste restaurant grease containing high free fatty acids (FFA) were used to evaluate the ability of triazabicyclodecene (TBD), a non-ionic, guanidine base, to function in a high free fatty acid environment. Reactions were carried out using both methanol and dimethyl carbonate (DMC) as methylating agents. Although increasing amounts of FFAs reduced the conversion of triglycerides (TGs), the TBD catalyst, using either methanol or DMC, adequately esterified FFAs at moderate temperatures (60 °C) but was not effective in converting triglycerides. The homogeneous catalyst work aided in elucidating the reaction chemistry. This work also studied the ability of a heterogeneous catalyst (TBD supported on a layered double hydroxide) to convert both FFAs and TGs in which 80% conversion was seen for neat canola oil and 58% conversion for unrefined oil. This study illustrates that the TBD/DMC process is an effective and commercially viable method for producing sustainable biofuels.

“…Since canola oil has only 4% palmitic acid within its fatty acid profile, palmitic acid was chosen as the test FFA to help isolate the effect of the reaction on FFA versus the triglycerides. Comparatively, canola oil contains 92% unsaturated fatty acids, including oleic acid, within its fatty acid profile …”

“…Due to their flexible structure comprising polar and non-polar residues, they are able to attach on interfaces, such as air/water or oil/ water interfaces, to form and stabilize foams and emulsions [5]. Additionally, great film-forming properties of rapeseed proteins were demonstrated [6][7][8]. However, methods to increase the hydrophobicity of rapeseed proteins while preserving their functional properties are demanded to enhance the applicability in the non-food sector.…”

Rapeseed proteins show good film-forming properties, giving them a promising potential as bio-based ingredients for the technical industry, e. g. for films and coatings. However, their hydrophilicity often poses problems in regard to water-stability of coatings. Protein modification using fatty acids is known to reduce hydrophilicity, however, it has not been tested to improve film-forming properties of rapeseed proteins before. In the present study, a rapeseed protein concentrate (RPC) was acylated at low and high modification degree using lauroyl chloride and oleyol chloride. The protein solubility was determined and the modified RPCs were used for the preparation of cast-films to measure the changes of mechanical properties (tensile strength, elongation at break), surface energy, oxygen permeability and light transmission. The protein solubility in water was lowered from 100% for the non-modified RPC to < 15% for highly modified RPCs at pH 7. The tensile strength of films increased by factors of 3.5 and 4 for highly modified samples, respectively. Surface energy and oxygen permeability revealed an increase of hydrophobicity that correlated with the modification degree. The light transmission was reduced by modification. The results confirm the increased hydrophobicity of acylated RPCs and demonstrate the potential of modified rapeseed proteins as an ingredient for technical products, such as packaging layers, coatings and adhesives.

A palavra "óleo" é usada para os triglicerídeos que normalmente são líquidos em temperatura ambiente, a figura 1 ilustra uma estrutura representativa de um óleo vegetal, que é basicamente constituído por diversos triglicerídeos, estes formados entre unidades de glicerol e diferentes cadeias de ácidos graxos.…”
