Conjugated linoleic acid (CLA) is a mixture of positional and geometric isomers of octadecadienoic acid with conjugated double bounds. Positive health properties have been attributed to some isomers, such as anticarcinogenic activity, antiartherosclerotic effects and reduction of body fat gain. Hence, oils rich in CLA such as Tonalin(®) oil (TO), normally obtained through alkaline isomerization...

Abstract A relation between oil uptake and cancer as well as induction of hepatic inflammation was shown earlier. It is discussed that the main oil oxidation products-hydroperoxides and carbonyls-might be the reason for the mentioned diseases. In this manuscript quantitative determination of aldehydes which are formed during oxidation of triolein-as a model substance-using the Rancimat 679 is d...

In the present investigation natural phenolic antioxidants were extracted from Jojoba seed waste. Samples of defatted jojoba meal (JSM), detoxified residue (DMR) and shell (JSH) subjected to extraction by using various solvents: 70/30 (vol/vol) ethanol/water, methanol/water 60/40 acetone/water. Total phenolics content (TPC) is measured according Folin-Ciocalteu method. In addition, solvent extr...

This work examines pressurized accelerated oxidation by a RapidOxy tester as an alternative method for determination of biodiesel stability. Sunflower oil-based was synthesized and treated with antioxidants: tert-butylhydroquinone (TBHQ) - synthetic antioxidant known its powerful protective effect, mixture bio-based compounds extracted from vinery waste, VWEeth. The potency TBHQ evaluated at va...

Abstract The purpose of this study was to evaluate the thermal stability rice bran extract (RBE) and analyze effect RBE on shelf-life sunflower oil quality characteristics baked cake. evaluated by a Rancimat test using oil. Properties such as moisture content, porosity, crumb density pore area cakes with synthetic antioxidant butylated hydroxytoluene (BHT) were compared. Sensory properties tast...

Cold-pressed camelina oil (CPCO) is exceptional seed with a unique fatty acid profile promoting health and wellness. Therefore, this work focused on estimating comparing the physicochemical properties sensory quality of eight CPCO samples available Polish market. All analyzed oils were rich in α-linolenic (ALA = 29.91–36.27%) contained low amounts saturated acids (SAFA 10.61–12.20%). Oxidative ...

This works aimed at investigating shelf-life behavior of extra virgin olive oil (EVOO) extracted from two cultivars “Arbequina” and “Moroccan Picholine” as a function storage time (8 weeks) accelerated conditions (60 °C). Our outcomes revealed significant variations between EVOOs both in terms the investigated physicochemical characteristics. These were also affected by temperature except for f...

Arbequina extra-virgin olive oils were flavored with lemon verbena (Aloysia citrodora) essential oil (0.1–0.4%, w/w), being evaluated quality parameters (free acidity, peroxide value, UV-extinction coefficients), oxidative stability, antioxidant and total reducing capacity. The kinetic-thermodynamic nature of the lipid oxidation was by Rancimat (110–150 °C). addition promoted capacities but, un...

In searching for new sources of oil, protein and gelatin researchers have investigated many wild plants, but our research group took a different approach: We looked at insects as oil, protein and gelatin source for both nutritional and industrial applications. According to Sudanese indigenous knowledge, many insects have food and medicinal uses. We targeted two of these insects for our research...

Improving the quantity and quality of olive oil extraction is considered crucial for producers not only in Jordan but also worldwide. The present study aimed to enhance yield from fruits without compromising its by applying an enzymatic treatment technique during malaxation stage process.
 enzymes that were used this cellulase, pectinase, a mixture both at ratio (1:1). Each there was added...
