oleoresin

• From gas chromatogram chart , in addition to less composition of volatile compounds , onion oleoresin contained more resin that has sharp flavor and pigment
  从气相色谱图上可以看出，洋葱油树脂中除含少量洋葱精油外，主要是沸点较高的倍半萜及代表辛香味的树脂成分、色素等。
• With the yield of concentration of sulfur compound as the evaluation index , the contrast between onion essential oil and onion oleoresin from dried onion powder by steam distillation , solvent extraction and soxhlet method was studied
  摘要以洋葱粉为研究对象，以含硫化合物浓度为评价指标，采用水蒸汽蒸馏、溶剂萃取法和索氏提取法进行洋葱精油与油树脂的比较研究。
• Using red peppers as raw materials , to extract capsaicinoids by the methods of soxhlet extraction and supercritical fluid extraction and supercritical fluid extraction and supercritical fluid extraction , then analysed and compared on the color value , yield and the percentage of capsaicinoids content of the capsicum oleoresin and capsicum red pigment , which were made by the two methods , and detect the quality of pigment
  摘要以红辣椒为原料，采用索氏提取超临界萃取和二次超临界萃取法，对两种方法得到的辣椒油树脂、辣椒红色素进行了色价、产率、辣椒素含量的分析比对，并对色素的质量进行检测。
• Results show when produce capsicum red pigment , soxhlet extraction and supercritical fluid extraction is a good method for its low cost and good quality of pigment ; using the method of supercritical fluid extraction and supercritical fluid extraction , the color value of capsicum oleoresin and the percentage of capsaicinoids content of the intermediate are higher
  结果表明，生产辣椒红色素，索氏提取超临界萃取是比较好的方法，成本低，所得色素质量也不错；二次超临界萃取的方法，中间产物辣椒油树脂的色价和辣椒素含量比较高。
