by employing the membrane filter press, both hardness of the palm stearin and yield of palm olein were enhanced, and higher fractionation efficiency was got.
采用隔膜压滤机,棕榈硬脂硬度提高、棕榈液油得率增加,分离效果好。
by studying on comparability , stearin fractions of lard obtained dry fractionationand hydrogenated cottonseed oil are chosen as raw materials of shortening.
通过相容性的研究,选择氢化棉油与干法分提固脂作为起酥油的原料。
stearin is harder and burns longer than unrefined tallow.
在19世纪早期到中期,蜡烛处理工艺使用alkali和sulfuric acid来提炼tallow,提炼后的产品就是stearin,stearin比未经提炼的tallow坚硬而且燃烧得更久。
