“…The results were almost consistent with the contents of β-sitosterol in quince [45], and sacha inchi [34]. The ratio of β-sitosterol in C. ovata seed oil was also higher than that in the soybean (58-58.2 %) [46], palm oil (59.1-61 %) [47] and rapeseed oil (54.2-61.2 %) [48]. Tocopherol is commonly called Vitamin E, which belongs to the fat-soluble vitamins.…”

In view of the growing demand for vegetable oil, currently exploration of some non‐conventional oils is of great concern. This study firstly analyzed the contents of fatty acids, phytosterols, and tocopherols in Catalpa ovata seed oil collected from four different Provinces in China. Then the composition of flavonoids as well as their antioxidant activities in defatted seed meal was determined. The results showed that the relative oil content in C. ovata seeds ranged from 24.0 to 36.0 % and seed oil was mainly composed of fatty acids linoleic acid (43.4–50.1 %), α‐linolenic acid (23.8–24.4 %), and oleic acid (13.1–16.2 %). The content of unsaturated fatty acids was up to 85.0 %. Sterol in seed oil mainly contained campesterol, stigmasterol, and β‐sitosterol. β‐sitosterol accounted for 74.0 % of the total sterol. The tocopherol content was 173.0–225.7 mg/100 g. Defatted seed meal from Hubei Province showed the highest content of total flavonoids (11 mg/g) and the strongest activities for DPPH radicals scavenging, ABTS radicals scavenging, and ferric reducing antioxidant power compared with other defatted seed meal in this study. Seven flavonoids were identified from C. ovata seed meal. These results suggest that C. ovata seeds may be developed as a new source of oil and can also be properly used in pharmaceuticals and cosmetics.

“…Experimental data were obtained as derived from one-stage molecular distillation using a KDL4 of UIC equipment with the following operating conditions: feed flow of 1.9 ml/min, feed temperature at 45 °C, condenser temperature at 25 °C, pressure of 10 -5 atm. Table 1 shows the composition of the raw material of the molecular distillation, where the major components of sunflower oil DD are presented, Naz et al (2014) reported similar data. Feeding from the distillation of the simulated oily mixture has the w FK mass compositions of the A, B, C and D pseudo components, which are shown in Table 2.…”

SUMMARY:A methodology for predicting the thermodynamic and transport properties of a multi-component oily mixture, in which the different mixture components are grouped into a small number of pseudo components is shown. This prediction of properties is used in the mathematical modeling of molecular distillation, which consists of a system of differential equations in partial derivatives, according to the principles of the Transport Phenomena and is solved by an implicit finite difference method using a computer code. The mathematical model was validated with experimental data, specifically the molecular distillation of a deodorizer distillate (DD) of sunflower oil. The results obtained were satisfactory, with errors less than 10% with respect to the experimental data in a temperature range in which it is possible to apply the proposed method. KEYWORDS: Modeling; Molecular distillation; Oily mixtures; PropertiesRESUMEN: Metodología para la predicción de propiedades de mezclas oleosas en el modelado matemático de la destilación molecular. Se presenta una metodología para la predicción de las propiedades termodinámicas y de transporte de mezclas oleosas multicomponentes, en la cual se agrupan los diferentes componentes de la mezcla en un número reducido de pseudocomponentes. Esta predicción de propiedades se utiliza en el modelado matemático de la destilación molecular que consta de un sistema de ecuaciones diferenciales en derivadas parciales, según los principios de los fenómenos de transporte y se resuelve mediante un método implícito de diferencias finitas mediante un código computacional. El modelo matemático fue validado con datos experimentales, específicamente de la destilación molecular de un destilado de desodorización (DD) de aceite de girasol. Los resultados obtenidos fueron satisfactorios, con un error menor al 10% en un rango de temperaturas.

“…Loganathan et al (2009) menunjukkan bahwa minyak sawit mengandung vitamin E 600-1000 ppm, fitosterol 300-620 ppm, karotenoid 500-700 ppm, skualen 250-540 ppm, fosfolipid 20-100 ppm, koenzim Q10 10-80 ppm, dan polifenol 40-70 ppm. Tabel 2 menunjukkan bahwa secara umum senyawa bioaktif yang paling banyak terdapat dalam DALMS adalah vitamin E. Distillate deodorizer dari berbagai jenis minyak nabati bervariasi dengan komponen dominan dalam distillate deodorizer minyak kedelai adalah fitosterol (Khatoon et al, 2010), minyak canola dan biji bunga matahari adalah fitosterol (Naz et al, 2014), minyak jagung adalah fitosterol (Majoni dan Wang, 2010), sedangkan Wan et al (2008) menyatakan bahwa minyak kedelai didominasi tokoferol. Jika dibandingkan dengan distillate deodorizer minyak lain, kadar tokoferol dalam minyak canola dan biji bunga matahari adalah 3,77-6,59% dan 6,51% (Naz et al, 2014), sedangkan DALMS mengandung vitamin E 4,77%.…”

Palm fatty acid distillate (PFAD) is a b y-product of palm oil refining that contains valuab le b ioactive compounds such as phytosterols, tocopherol, tocotrienols, and squalene which acummulates in unsaponifiab le fraction (USF). In emulsion form, USF will b e convenien t and easy to use as food supplements or fortificants. Microemulsion is a type of emulsion that has stab le droplet sizes of less than 10 m. Hence, the b est emulsifier for USF microemulsion is important to b e determined. The USF microemulsion was prepared b y homogenizing the sample mixtures at 12.000 rpm for 20 min at USF concentration of 10% (w/v) with lecithin and tween 80 as the emulsifiers at concentratiosn of 0.5 , 1.0, and 1.5% (w/v). The microemulsions were analyzed for their viscosity, stab ility, and particle size distrib utions, as well as microstructures. The results showed that characteristics of microemulsion were affected b y emulsifier types and concentrations. Tween 80 produced b etter microemulsion than lecithin as indicated by more stab le emulsions, smaller droplet sizes, and narrower ranges of droplet size distrib utions. Increasing lectihin concentrations resulted in a narrower droplet size distrib ution b ut the average droplet size was not always smaller. Conversely, increasing tween 80 concentrations increased the average droplet sizes and ranges of particle size distrib utions. The most suitab le emulsifier for USF microemulsion was tween 80 at concentration of 0.5%. This microemulsion contained b ioactive compounds derived from USF, namely vitamin E (mainly tocotrienols), phytosterols, and squalene.
