Effects of temperature on the activity of antioxidant enzymes in larvae of Bactrocera dorsalis (Diptera Rantala M.J., Gryzanova E.V. The effect of drying temperature on the antioxidant activity of thyme extracts. The best extraction conditions were 40% ethanol, 60 min extraction time, and extraction temperature of 30C. These values decreased with increasing temperature and time. 3.2 Effects of different extrusion temperatures on phenolic composition Phenolic acid is an important source of antioxidant activity and has two forms in rice: the soluble form, including soluble-free and soluble-conjugated forms; and the insoluble-bound form, where the acids are esterified to cell walls. Today, this bioprocess technology aims at the use of microorganisms and their enzymes, through acidification, alcoholisation, proteolysis, and/or Temperature and Time of Steeping Affect the Antioxidant Properties of White, Green, and Black Tea Infusions. Results showed that cloves had the highest antioxidant activity while the cinnamon, turmeric and sumac had a appreciable level of antioxidant activity. Strawberry fruit stored at 10C or 5C showed higher antioxidant capacity, total phenolics, and anthocyanins than those stored at 0C. This study investigated the effect of roasting conditions, temperature ranging from 110 to 150C and time duration 15-35 min, on the level of flavanol and procyanidin (FP), total proanthocyanidin (PAC) and antioxidant activity of fermented cocoa beans in Southern Taiwan. Effects of temperature, pH and enzyme to substrate ratio on the AA were evaluated and compared using response surface methodology. A water-rich solvent system (90:10) increased the antioxidant activity, which suggested that the samples were rich in antioxidant compounds. Abstract: The effect cooking temperature(100-180c) and contact time (10-30min) ofon the leaf extract Typhonium trilobatum (Kharkol) was explored for phytochemical profile and in vitro antioxidant activity. The different kinetic models used for antioxidant activity at different heating temperatures highlighted the effect of the activity of different reactants in the Maillard reaction, which may be due to differences in the temperature sensitivity of the various steps of the Maillard reaction (Van Boekel, 2001). Kedawung leaves (parkia biglobosa) have high levels of flavonoids so they have antioxidant activity.
Effect of extraction temperature and technique on phenolic compounds and antioxidant activity of Tamarindus indica seeds. In recent years, herbal Chemical and antioxidant properties of pomegranate cultivars grown in the Medi-terranean region of Turkey. The short vegetative occurrence of Allium ursinum limits its availability. In this study, cucumber seedlings were exposed to heat shock in greenhouses, and the responses of photosynthetic properties, carbohydrate metabolism, The present study aimed to evaluate the effect of potassium bicarbonate (KHCO3) on morphophysiological parameters, phenolics content and the antioxidant activity of basil under drought conditions. Three OTP products were obtained by drying of fresh tomato at 60, 80 and 100oC oven until constant weight was obtained. Phenolic compounds, flavonoids, total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity were estimated under the four temperature treatments. Many reports indicate that thermal treatment affects the antioxidant activity of various food samples. The aim of this study was to investigate the influence and mechanisms of temperature on the antioxidant system in fresh-cut daylily flowers (Hemerocallis lilioasphodelus L.; used for food consumption) during storage. Date juice was concentrated at 100 and at "60 in vacuum". ABSTRACT The effects of pepsinassisted hydrolysis conditions on the antioxidant activity (AA) of porcine hemoglobin hydrolysate (PHH) were investigated in this study. Correlation Between Phytochemical Composition and Antioxidant Activity. J Food Technol Pres 2018;2(3):15-19. While (+)-catechin (92.62 mg/kg), 1,2-dihydroxybenzene (132.15 mg/kg), gallic acid (107.01 mg/kg), and 3,4-dihydroxybenzoic acid (74.59 mg/kg) are the key phenolic compounds in fresh plum, (+)-catechin, 3,4-dihydroxybenzoic acid, 1,2 The effect of the air-drying temperature on drying kinetics, antioxidant capacity and vitamin C content of the papaya was investigated. In contrast to pH, heat had no effect on antioxidant activity of cHb. phenolics content in the two of tested cultivars, and antioxidant activity, determined by DPPH and ABTS methods. Phys. The effects of temperature and heating time on the degradation and antioxidant activity of anthocyanin compounds from roselle petals (Hibiscus sabdariffa L.) have been evaluated from this research. Effect of air temperature on drying kinetics, vitamin C, antioxidant activity, total phenolic content, non-enzymatic browning and firmness of blueberries variety O'Neil.
