White pepper is added as a spice to goose fat in the food industry (particularly in the liver paté industry) and causes the
development of undesirable flavors. In the present study, we demonstrate that white pepper exhibits lipolytic activity when
reacted with goose fat in a hydrophobic system. Temperature and pH dependence measurements suggested that two enzymes or isoenzymes
with optimal temperatures at 55 and 85°C, and with optimal pH at 7 and 9, are involved. Wet sterilization of the white pepper
irreversibly inactivates its lipolytic activity. Dehydration, destroyed while remoistening, recovered the catalytic activity
of the pepper. The reaction obeys classical Michaelis-Menten kinetics at 85°C. 相似文献

The paper introduces a method for characterization of silicone rubber and titanium powder in high velocity compaction using the split Hopkinson set-up. The impact test data has been used to estimate parameters in constitutive models for rubber and powder. A finite element study has been performed with different geometrical design of the high velocity compaction of titanium powder against an aluminium mandrel using a rubber mould as pressing medium. One goal of this study is to investigate if and how the manufacturing method can be applied for making dental copings.A conclusion of the experimental work is that it is possible to characterize rubber material and powder material for high velocity compaction of metal powder by the use of a modified split Hopkinson pressure bar set-up. The numerical simulation shows qualitatively good agreement with the experience from practical tests. In conclusion, the work shows the possibility to numerically study the geometric design and to optimize the densification behaviour of a complex high velocity compaction process. 相似文献

用钛白副产的硫酸亚铁浸锰制备高纯二氧化锰 总被引:5,自引:0,他引:5
以低品位的贫软锰矿为原料,对用生产钛白副产的硫酸亚铁直接浸锰、浸出液除杂、碳酸锰沉淀、碳酸锰焙烧及二氧化锰精制制备二氧化锰的工艺条件进行了研究。实验得到硫酸亚铁浸锰的最佳工艺条件为:浸锰温度70℃,浸锰时间3h,硫酸初始浓度2.1mol/L,矿粉粒度〈150μm,硫酸亚铁加入量为其理论量的120%,固液质量比1:3。碳酸锰焙烧的适宜条件为:焙烧时间4~5h,焙烧温度320—340℃,焙烧料翻动时间10-15min。按该条件浸锰并制备高纯二氧化锰,锰的浸出率可达98.5%以上,产品质量符合ZBG13001-1986一级品标准。该工艺为贫软锰矿的开发利用及钛白粉厂的硫酸亚铁渣的综合利用开辟了一条新途径。 相似文献

<正>“十五”计划以来,涂料行业强劲发展,从而也带动了涂料原料各行业的急剧发展,并引发了涂料用白色颜料品种之间的此消彼长,即,立德粉苦苦挣扎;钛白粉高歌猛进的变局。挣扎的,会是一个什么样的结果?猛进的,应是一个怎么样的前景?一个时期以来,行业内外,各色人等,重重思索,纷纷议论,莫衷一是。媒体上,不断出现相关论文、报道。可喜的是,问题受到了关注;可惜的是,所议所论,中的者少;误导者多。令人为之扼腕。 相似文献
