A model to represent the discolouration of dried powder of carrots as a function of temperature was developed. Two types of carrots, Asian and European, containing large amount of lycopene and β-carotene, respectively, were tested. The dried powder was stored under an atmosphere with O2and at three different temperatures, 5,20 and 35°C. The surface colour of the powder was monitored during storage by a Hunter colour ratioa/b. In the proposed model, the rate of oxidation was assumed to be represented by the product of the fraction of concentration of oxidized pigment at arbitrary time and a specific rate of oxidation of pigment. The rate parameters in the proposed model were calculated by fitting the experimental data with smooth curves by trial and error at the end of the induction period but before discolouration took place. The frequency constant and activation energy, expressing the temperature dependence of the rate parameters, were expressed by the Arrhenius relation. The simulation results of a Hunter colour ratioa/bof dried powder at 25°C showed good agreement with the experimental data, suggesting that the proposed model was effective for the prediction of discolouration of dried powder of both types of carrot. The use of the induction period in the manner described may enable the shelf life of dried powder to be predicted. 相似文献

The fractional outflow rate of water from the rumen, measured as the rate of disappearance of the chromium complex of ethylenediamine tetra-acetic acid, was related to a number of dietary factors. A multiple regression equation was derived which expressed fractional outflow rate as a function of the intakes of dry matter, ash, acid-detergent fibre and crude protein.The data analysed consisted of 243 observations for sheep on 59 diets, including forage, concentrate and mixed diets. The ranges covered by the data were: fractional outflow rate 0.7–3.6 day?1; dry matter intake 560–1400g/day; ash 4–30%, acid-detergent fibre 7–41%, crude protein 5–26 % of dry matter; there were no observations for sheep of less than 34 kg liveweight.The equation accounted for 56·3 % of the total variance. Between-sheep variance could not be calculated for the whole of the data but was undoubtedly substantial since, for a sixth of the data, it was known to account for 38 % of the total variance. 相似文献

为探究腔体初始容积对压电泵性能的影响,设计了双腔体并联压电泵.通过理论分析,确定了双腔并联压电泵能够工作时泵腔初始容积的取值范围,根据理论公式设计制作了6种不同腔体初始容积的双腔并联有阀压电泵样机,对泵腔初始容积的变化与泵工作性能关系进行研究.在110 V工作电压下,工作频率小于400 Hz范围内,用压电双晶片进行驱动,分别以液体水和空气为介质,对不同压缩比（压电振子振动产生的泵腔容积变化量与泵腔初始容积的比值）下的并联泵进行了试验测试.结果表明,当泵送液体水时,压缩比为1/18时泵的整体输出流量最好,最大输出流量可达1 330 mL/min,压缩比越大,泵的输出压力和自吸能力越好,最大输出压力和自吸高度分别为58.5 kPa和69 cm;当泵送气体空气时,压缩比越大,泵的输出能力越好,最大输出流量和压力分别为850 mL/min和6.5 kPa,当压缩比小于1/32时,泵已经失去了输出气体能力. 相似文献

为了研究一种利用微水头发电的水车装置,利用Fluent软件流体体积(VOF)模型模拟明渠无压流动,选用SST k-ω两方程湍流模型和滑移网格旋转模型对不同叶片数的水车在不同转速下进行非定常模拟.结果表明:3叶片水车效率区最为宽广,最优效率最高;3叶片水车上游局部湍流黏度较大,影响范围较小,而8叶片水车上、下游湍流黏度较为平均,影响范围较大;相同工况下,增加叶片数会增强水车的阻塞效应,使上、下游水位差平均增大,但可降低水位差的波动,水位差平均值增大将降低水车出力,水位差的波动对水车轴系的稳定性产生不利的影响;相同工况下,增加叶片数可以提高水车运行中转矩波动的稳定性,但会降低水车的出力,转矩波动使水车在运行中受到周期性不平衡力矩的作用,引起水车结构剧烈振动和叶片疲劳损伤. 相似文献
