mathematical modeling of green pepper drying in microwave-convective dryer
in this study, green pepper was dried by a laboratory scale microwave-convective dryer. the effects of microwave power on drying rate, effective moisture diffusivity, and energy consumption of green pepper were studied at four different microwave powers of 180, 360, 540, and 720w. the drying data were fitted to the four thin-layer drying models. the moisture reduction of the green pepper sample...
متن کاملAntioxidant activities of two sweet pepper Capsicum annuum L. varieties phenolic extracts and the effects of thermal treatment
Objectives: Sweet peppers Capsicum annuum L. (C. annuum) are an excellent source of vitamins A and C as well as phenolic compounds, which are important antioxidant components that may reduce the risk of diseases. The objective of this study was to evaluate their antioxidant activity under various temperatures. Materials and Methods: To compare the antioxidant activity in various temperatures (2...
متن کاملModelling kinetics of thermal degradation of colour in peach puree
Optimisation of thermal processes relies on adequate degradation kinetic models for food safety and quality. In order to use peach puree as a model food to further validate calculated optimal conditions, isothermal experiments, using peach puree, were performed between 110°C and 135°C. Colour was quanti®ed using the L, a, b system. Two combinations of these parameters, La/b and Total Colour Di...
متن کاملThermal and Microwave-Assisted Oxidative Degradation of Poly(ethylene oxide)
The kinetics of the thermal and microwaveassisted oxidative degradation of poly(ethylene oxide) were determined with potassium persulfate as the oxidizing agent. Gel permeation chromatography was used to determine the variation of the molecular weight with time. The degradation was studied as a function of the temperature and persulfate concentration, and it was found that the degradation rate ...
متن کاملEffect of thermal blanching and of high pressure treatments on sweet green and red bell pepper fruits (Capsicum annuum L.)
The effect of pressure treatments of 100 and 200 MPa (10 and 20 min) and of thermal blanching at 70 C, 80 C and 98 C (1 and 2.5 min), on sweet green and red bell peppers was compared. Pressure treated peppers showed a lower reduction on soluble protein and ascorbic acid contents. Red peppers presented even an increased content of ascorbic acid (15–20%), compared to the untreated peppers. Peroxi...
