The saturated and unsaturated fatty acid of extracted horse oil (control) was separated by low-temperature crystallization, then the cooling curve, cloud point, iodine value, thermal property DSC were evaluated. solid phase liquid during crystallization processing. Before separation, point near 25.6°C (54.3 min) after could observed at around 7.6°C (289.7 29.4°C (36.5 min), respectively. value ...
In this paper, we present a facile method for the fabrication of a functionally integrated device, which has the multi-functions of the oil-containment boom, oil-sorption material, and water/oil-separating film, through a single immersion step in an ethanol solution of stearic acid. During the simple immersion process, the two dominant factors of superhydrophobicity, surface roughness and low-s...
The basic unit operations in vegetable oil processing are shown in Figure 4. Oil is extracted from plant material (oilseeds) using a solvent, usually hexane. Published research indicates that about 50}70% of the hexane can be recovered and recycled using nanoRltration membranes instead of the evaporators used today, thus reducing energy consumption substantially. The extracted crude oil is most...
Enzymatic transesterification by using lipase as catalyst has become more attractive for the production of biodiesel due to easy separation of products such as glycerol and fatty acid esters. Comparative studies of enzyme catalyzed transesterification of three less attended non edible oils (jatropha, karanja and putranjiva) have been discussed. The maximum yield has been obtained at 3:1 molar r...
Nowadays, food contamination by mineral oil (MO) is a very important issue and its presence in edible oils is widely documented. Mineral oils are hydrocarbons mixture of petrochemical origin containing mainly two families of compounds, namely mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). The most used approach for mineral oil analysis is liquid chromato...
Kaewchai, S. and Prasertsan, P. Screening and application of thermotolerant microorganisms and their flocculant for treatment of palm oil mill effluent Songklanakarin J. Sci. Technol., 2002, 24(3) : 413-420 Among fifteen thermotolerant polymer-producing isolates, three strains SM 29, WD 90, and SM 38 produced polymer posessing very high flocculating activities (24.81, 14.63 and 10.84, respectiv...
Color and size are two important attributes for quality evaluation of most food and bioproducts. Many of the quality factors affecting oil palm and white powder starch are determined primarily by visual inspection. Such inspections determined market price and to a certain extent consumers' preferences. However, the inspection of oil palm and white powder starch is a very repetitive and tedious ...
In this work, new magnetic amphiphilic composites were prepared by chemical vapor deposition with ethanol on the surface of hydrophilic natural chrysotile matrix containing Fe catalyst. XRD, Raman, Mössbauer and SEM analyses suggest the formation of a complex nanostructured material composed of hydrophobic carbon nanotubes/nanofibers grown on the hydrophilic surface of the MgSi fiber mineral an...
Volatile oil from the root bark of Oplopanax horridus is regarded to be responsible for the clinical uses of the title plant as a respiratory stimulant and expectorant. Therefore, a supercritical fluid extraction method was first employed to extract the volatile oil from the roots bark of O. horridus, which was subsequently analyzed by GC/MS. Forty-eight volatile compounds were identified by GC...
3D printing and nickel coating greatly enhance the membrane permeability selectivity for oil/water separation.
