Vegetable oils are ideal alternative solvents for extracting fat-soluble substances. Here, response surface methodol., conventional anal., and headspace-gas chromatog.-mass spectrometry were used to evaluate the effect of an extraction process on the carotenoid yield, changes in physicochem. parameters, and flavor quality of cottonseed oil (CSO). An optimal carotenoid recovery rate of 80.3% was obtained when the ultrasonic power was 213 W, the extraction time was 36.0 min, and the temperature was 44.6°C. Although acid (0.25 mg KOH/g), peroxide (9.90 meq/kg), and p-anisidine (0.11) values of carotenoid-enriched cottonseed oil (CECSO) increased relative to the corresponding values for CSO, its 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity, carotenoid and total phenolic content also increased, reaching 64.2%, 49.1μg/mL, and 320 mg gallic acid equivalent (GAE)/100 g oil, resp. Addnl., 14 compounds, including nine aldehydes (84.7-103μg/g), three alcs. (9.41-10.8μg/g),one acid (0.37-1.24μg/g), and one heterocycle (4.19-5.32μg/g), were identified as characteristic compounds in CSO and CECSO. Further, significant differences between the two types of oils were observed in aroma-related substances . This study provides a reference for the application of carotenoid-enriched cottonseed oil in food, health products and cosmetics. In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4Product Details of 3391-86-4).
Oct-1-en-3-ol (cas: 3391-86-4) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Product Details of 3391-86-4
