- Abstract:
- ... In this study, two important isomers of CLA, i.e. c9,t11 and t10,c12, were produced up to ca. 73% of total fatty acids, employing alkali isomerization of safflower oil, followed by purification with only one-step urea crystallization to 85.6%, while the recovery of the purification process was 35%. Interesterification (acidolysis) of purified CLA with canola oil was then conducted by Thermomyces l ...

- Abstract:
- ... Pomegranate seeds are byproducts of the pomegranate juice industry. Because of the presence of large amounts of certain pharmaceutical and nutraceutical components in the seeds, a proper extraction method to obtain these components is highly demanded in the food industry. In this study, the effect of different extraction methods on the total phenolic contents of the oil extracted from pomegranate ...

- Abstract:
- ... The objective of this work was to study the evolution of oxidation under oxidative stability index (OSI) conditions using the Rancimat apparatus. Sunflower oils with different degrees of unsaturation (conventional high-linoleic sunflower oil, genetically modified high-oleic sunflower oil, and a 1 : 1 mixture of both of them) and virgin olive oil were used. The sunflower oils were tested at 100 °C, ...

- Abstract:
- ... Alkenyl succinic anhydrides (ASA) were obtained by reaction between maleic anhydride and high-oleic sunflower oil (HOSO) esters. A kinetics study of the maleinization of alkyl esters indicated that the maleinization reaction was second order overall and first order with respect to the individual reactants, and the activation energy was 77.2 ± 3.3 kJ/mol in the investigated temperature range (185-2 ...

- Abstract:
- ... Co-fermentation of lignocellulose-based carbohydrates is a potential solution to improve the economics of microbial lipid production. In the present paper, experiments were performed to optimize the media composition for lipid production by the oleaginous yeast Lipomyces starkeyi AS 2.1560 through co-fermentation of glucose and xylose (2 : 1 wt/wt). Statistical screening of nine media variables wa ...

- Abstract:
- ... Microwave-assisted hydrodistillation (MAHD) has recently gained attention for the extraction of essential oils. A concern with the use of MAHD is the possibility of sample deterioration during the extended exposure to microwave irradiation. In this study, MAHD was applied as a new and green technology for the extraction of essential oil from Zataria multiflora Boiss. (Shirazi thyme) aerial parts. ...

The moisture sorption isotherms of two-phase solid olive oil mill by-product (SOB) were measured at different temperatures (15-50 °C) in order to thoroughly know the hygroscopic properties of this material. SOB is like a slurry with a high water content (60-70%). It is obtained in the olive oil two-phase extraction process and is currently used as the raw material for obtaining pomace oil by extra ...

- ... The human food and animal feed industry and even oleochemical manufacturing processes might be exposed to contamination from products of BSE-infected cattle. Although the most important oleochemical raw material, i.e. tallow, is not considered to be a causal factor for BSE, the potential risk associated with tallow-derived products has to be evaluated in the light of the specific production proces ...

Free fatty acids (FFA), fatty acid methyl esters (FAME) and monoacylglycerols (MG) of vegetable oils or animal fats have very close molecular sizes and they cannot be baseline-separated on a single Phenogel column (100 Å, 300 mm x 7.8 mm ID, 5 μm) by using tetrahydrofuran (THF) as the mobile phase. When toluene is ...

The effects of a dietary administration of high-oleic sunflower oil (O) (about 85% oleic acid) to pigs, either or not in combination with α-tocopheryl acetate (E), were assessed with regard to the composition of the triacylglycerols, phospholipids and the level of vitamin E in Italian heavy pork meat. Four different diets with the same lysine/calorie ratio (control; 3% O; 250 mg/kg E; 3% O + 250 m ...

This study determined the effect of adding mixed phytosterols, at various concentrations, on the thermal polymerization and oxidative stability index (OSI) of soybean and high-oleic sunflower oils. The indigenous tocopherols and phytosterols were removed from the oils by molecular distillation. Pure phytosterols were added back to these stripped oils at concentrations of 0.25, 0.5, 1, and 2.5 wt-% ...

- Abstract:
- ... The antioxidant properties of some single components and the total antioxidant activity of extra-virgin olive oil have been evaluated by the oxygen radical absorbance capacity (ORAC) method. The total ORAC of the extra-virgin olive oil was found to be positively correlated with the concentration of total polyphenols, which are important to the shelf life of the product. Among the single phenolic c ...

The phospholipid composition is measured by newly developed HPLC-LSD and ³¹P-NMR methods. The phospholipid compositions of the three types of lecithin show small differences, while the fatty acid composition is largely equivalent to the oil source. Regulatory spe ...
