Bacterial response to increasing amounts of the volatile oils varies significantly according to species of bacteria tested. Among the four species examined, Escherichia coli was the most resistant to the oils, followed by Neisseria sicca, Bacillus subtilis, and Staphylococcus aureus. The oils of Artemisia tridentata seem to have the same degree of antibacterial action as oils obtained from A. n...

Since we have been exposed to excessive amounts of stressors, aromatherapy for the relaxation has recently become very popular recently. However, there is a problem which responds to light with the essential oil used by aromatherapy. It is generally believed that singlet oxygen is implicated in the pathogenesis of various diseases such as light-induced skin disorders and inflammatory responses....

The non-triglyceride structuring of liquid oils, so-called oleogelation, enables new and more beneficial product designs. Natural waxes have proven to be excellent oleogelators due their wide availability low inclusion levels. However, vary greatly in compositions contain different proportions major components: wax esters (WE), fatty acids (FA), alcohols (FaOH), hydrocarbons (HC). In this study...

The production of confectionery products, especially those coated with chocolate or glaze, faces the challenges selecting high-quality and technological fatty bases for glaze filling on a daily basis. In nature, amount vegetable oils that have an optimal acid triglyceride composition use as such base is significantly limited. Indeed, most fats require partial hydrogenation stage, is, change in ...

Mineral oils (also known as base oils, mineral base oils or lubricant base oils) are chemical substances prepared from naturally occurring crude petroleum oil. Crude oil is distilled first at atmospheric pressure and then under high vacuum to yield vacuum distillates and residual fractions that can be further refined to mineral oils. Mineral oils refined from petroleum crude oils are complex an...

Soybeans produced by induced mutation breeding and hybridization were cracked, flaked and hexane-extracted, and the recovered crude oils were processed to finished edible oils by laboratory simulations of commercial oil-processing procedures. Three lines yielded oils containing 1.7, 1.9 and 2.5% linolenic acid. These low-linolenic acid oils were evaluated along with oil extracted from the culti...

background: obesity is caused by several factors while sedentary lifestyle and excessive energy intake are the most important ones. obesity could be due to abnormal calcium metabolism, and a high calcium intake may prevent obesity. studying serum calcium level, albumin, and triglyceride concentrations, we searched for probable correlation between serum calcium level and anthropometric data of t...

background and objective: quality control is one of the most important components in order to improve quality assurance in laboratories during analytical steps. for this purpose, coefficient of variation plays an important role. due to the fast improvement in technology, application of inferential statistics for the comparisons of laboratory techniques, including instrument and chemicals and fa...

High-oleic acid soybean oil (H-OSBO) is a trait-enhanced vegetable oil containing >70% oleic acid. Developed as an alternative for trans-FA (TFA)-containing vegetable oils, H-OSBO is predicted to replace large amounts of soybean oil in the US diet. However, there is little evidence concerning the effects of H-OSBO on coronary heart disease (CHD)(6) risk factors and CHD risk. We examined and qua...

In our study, we characterized the antioxidant activity and oxidative stability of cold-pressed macadamia, avocado, sesame, safflower, pumpkin, rose hip, Linola, flaxseed, walnut, hempseed, poppy, and milk thistle oils. The radical scavenging activity of the non-fractionated fresh oil, as well as the lipophilic and hydrophilic fractions of the oil was determined using a 1,1-diphenyl-2-picrylhyd...
