BACKGROUND Alongside flour, fat is the key ingredient of sponge cakes, including those with long shelf lives. It is an unstable food component, whose quality and nutritional safety depend on the composition and pres- ence of oxidation products. Consumption of fat oxidation products adversely affects the human body and contributes to the incidence of a number of medical conditions. Qualitative c...

recently, subcritical water extraction (swe) has been well known as a green technology for extraction of bioactive compounds from plants. in this study, subcritical water extraction, ultrasound assisted extraction (uae) and shaker solvent extraction (sse) were compared for extraction of phenolic compounds from fig (ficuscarica) pulp and skin. antioxidant activity of the extracts was evaluated u...

4 different plant species belonging to the same family mint (Mentha piperita), sage (Salvia officinalis), rosemary (Rosmarinus lavender (Lavandula angustifolia) were harvested from Afyon region. Total antioxidant and phenolic contents analyzed by DPPH Folin-Ciocalteu method. The effect of extra virgin olive oils oxidation stability was tested means rancimat According analysis results, M. piperi...

This study aimed to search for the optimum antioxidant mixture improvement of stability high-oleic sunflower oil. Seven antioxidants including vitamin E, phytic acid, bamboo leaves, rosemary extract, tea polyphenols, ascorbyl palmitate (AP) as well polyphenol (TPP) were used. Peroxide value, free radicals and Rancimat induction time results all proved that TPP was best single antioxidant. There...

g-oryzanol is one of the strongest antioxidants. it inhibits oxidation and is only present in rice bran. this composition decrease cholesterol, which decreases the risk of atherosclerosis. ther prestn study extracted antioxidant from two varieties of rice bran (zayandeh rood and sazandegi) using methanol solvent and percolation. the extracts were added to edible oil without antioxidants in 100 ...
