The Impact

The present study aimed to evaluate the impact of industrial processing (neutralization/degumming, bleaching, and deodorization) on physicochemical characteristics of soybean oil and soybean oil deodorizer distillate (SBO-DD) collected from two different industries. The substantial impact of processing was observed on all physicochemical parameters except the iodine value (IV) and saponification value (SV). Gas chromatography-flame ionization detector (GC-FID) and Gas chromatography-mass spectrometry (GC-MS) analytical techniques were used for the quantification of individual fatty acids, sterols, and 3-monochloropropane diol (3-MCPD) ester. Among the fatty acids, palmitic and linoleic acids were present at higher concentrations in all processing stages. Among sterols, β-sitosterol was found to be higher (25.65 and#181;g/g) in crude soybean oil and reduced to 16.44 and#181;g/g after processing till the final deodorization stage. 3-MCPD ester was developed during the neutralization/degumming process and further increased during bleaching and deodorization up to 315 and#181;g/kg, respectively. SBO-DD was found to be a rich source of total and individual sterols as compared to crude or processed soybean oil. High free fatty acid (FFA) level in deodorizer distillate indicated that SBO-DD is a potential source of biodiesel production.

Canola Oils

Aim of present study was to evaluate quality of three collected sets of canola oil containing crude oil, neutralized oil, bleached oil, deodorized oil and canola oil deodorizer distillate (DD) form three different edible oil processing industries. Physiochemical properties such as moisture, color, free fatty acid (FFA), acid value (AV), peroxide value (PV), p-Anisidine value (AV), total oxidative (totox) value, saponification value (SV), iodine value (IV), unsaponifiable matter and soap content were evaluated. The results of the present study indicated that each stage of processing has different impact on the determined quality parameters. Overall processing was well controlled and final product i.e. refined, bleached and deodorized (RBD) canola oil was found to be fit for human consumption. Only soap contents should be further controlled during neutralization process to avoid extra processing time and losses in the bleaching process. High FFA contents in DD samples indicated that it could be used as a potential and cheap source for biodiesel production.

Abundant Fatty Acid

There is evidence that secondary metabolites are involved in the fungal pathogenicity and virulence of Neofusicoccum spp. Fatty acids may also influence the plant–pathogen interaction but, so far, no information is available on their production by species of Neofusicoccum associated with Botryosphaeria dieback, which is a well-known syndrome of several plants with a complex etiology. In the present paper, the production of fatty acids in liquid medium, by strains of N. vitifusiforme and N. parvum associated with declining Sicilian vine plants, was evaluated. Data, acquired via gas chromatography–mass spectrometry (GC/MS), show the presence of linoleic acid as the most abundant fatty acid produced by both examined strains. In addition, the pathogenicity of N. vitifusiforme was tested on 2-year-old grapevine plants of cv. Inzolia.

Triasetin is a bioaditif to increase the octane number of the gasoline. Triasetin was generated from the reaction between giserol and acetic acid. Glycerol is a byproduct of biodiesel production. Triasetin production can reduce glycerol which is actually a waste by converting it into bioaditif having higher value. The reaction can be accelerated by addition of catalysts either solid or liquid catalyst. The reaction in this study used a solid catalyst types Silica Alumina. The reaction takes place in the three-neck flask reactor which is equipped with heating unit, mixers, and tools to take samples at regular intervals. Variables used in this research is the variety of reaction time and the reaction temperature (70, 80, 90, 100, and 1100C). The concentration of triasetin obtained will be known through the analysis of Gas Chromatography - Mass Spectrometry (GC-MS). The results of the analysis of GC or GC-MS treated or counted so getting glycerol conversion and selectivity of triasetin. The highest glycerol conversion 8,45% occurs at a temperature of 700C the reaction time of 90 minutes with triasetin selectivity 100%.
