Oxidative Stability Analysis of Selected Oils from Unconventional Raw Materials Using Rancimat Apparatus

نویسندگان

چکیده

This study aimed to evaluate the quality of selected oils from seeds herbs and vegetables (basil, fenugreek, coriander, tomato, garden cress, parsley, dill), especially their oxidative stability. The were tested for oxidation degree (acid value, peroxide p-anisidine TOTOX indicator, specific extinction under ultraviolet light), colours, content carotenoid chlorophyll pigments, fatty acid composition, indicators lipid nutritional quality, stability, kinetics parameters (Rancimat). Principal component analysis was applied identify a correlation between oils’ parameters. results compositions show that basil oil good source omega-3 acids. Coriander seed found be most resistant oxidation, containing mainly monounsaturated highest value activation energy calculated fenugreek (94.18 kJ/mol), lowest dill (72.61 kJ/mol). However, characterised by constant reaction rate at 120 °C—3.0679 h−1. colour determined L* parameter oxidizability had significant influence on stability oils, coefficients r = −0.88 0.87, respectively.

Fats and oils as oleochemical raw materials *

Vegetable oils and fats are important constituents of human and animal foodstuffs. Certain grades are industrially used and, together with carbohydrates and proteins, are important renewable resources compared to fossil and mineral raw materials, whose occurrence is finite. In concepts for new products, the price, performance, and product safety criteria are equally important and have a corresp...

Oils and fats as renewable raw materials in chemistry.

Oils and fats of vegetable and animal origin have been the most important renewable feedstock of the chemical industry in the past and in the present. A tremendous geographical and feedstock shift of oleochemical production has taken place from North America and Europe to southeast Asia and from tallow to palm oil. It will be important to introduce and to cultivate more and new oil plants conta...

Blending of soybean oil with selected vegetable oils: impact on oxidative stability and radical scavenging activity.

BACKGROUND Soybean oil may protect against cancer of the breast and prostate. It may also exert beneficial influence in combination with other oils. Here, blends (20%, v/v) of sea buckthorn oil (SEBO), camellia oil (CAO), rice bran oil (RBO), sesame oil (SEO) and peanut oil (PEO) with soybean oil (SBO) were formulated. MATERIALS AND METHODS Oxidative stability (OS) and radical scavenging acti...
