Extraction of total carotenoids from calendula officinalis and their effects on the oxidation stability of mustard oil
نویسندگان
چکیده
Extraction of carotenoids was carried out from Calendula officinalis (English marigold) flowers and their effects on the oxidation stability of mustard oil under light storage was determined. Four solvents viz., hexane, acetone, ethanol and tolune were used for extraction of total caroteinoids.The carotenoid extract of the calendula flowers obtained was incorporated in mustard oil at 10, 25 and 50 ppm concentrations to prevent oxidation in oil samples placed in 20w illuminating closed chamber.The antioxidant effectiveness of carotenoid extract towards mustard oil was dependent upon concentrations. Samples were observed to determine peroxide and TBA values after storage period of 0,1,3, 5 and 7 days. Samples incubated with carotenoid extracts of calendula flowers exhibited lower values of Peroxide and TBA values as compared to control samples. Minimum values of peroxide and TBA values were observed in case of oil samples incubated with 50 ppm concentrations as that of 25 and 10 ppm concentrations.

متن کاملIdentification of chemical composition and comparison of antioxidant effects of marigold (Calendula officinalis L.) essential oil with butyl hydroxytoluene in canola oil stability
Background and Aim: Oxidation of vegetable oils is a major challenge in the food industry. Canola oil is prone to oxidation because of high unsaturated fatty acids. An effective way to prevent oxidation of oils and fats is addition of antioxidants. However using synthetic antioxidant due to the possibility of toxic and carcinogenic effects is limited. Thus, todays essential oils from aromatic p...
