胭脂红酸是一种天然着色剂，可从Dacampius coccus Costa昆虫物种（胭脂虫）雌性的干燥身体中获得。胭脂红酸是从胭脂虫中提取的主要色素。它的主要用途是化妆品，食品和制药应用，它也可以有纺织和塑料应用。传统的萃取方法存在萃取时间长、选择性差、萃取效率低等缺点。此外，这些常规技术需要有毒溶剂。在这项工作中，新的提取方法进行了研究，以避免上述缺点。加压液体萃取（PLE）和超临界流体萃取（SFE）技术提供高选择性和短萃取时间。(C)2011爱思唯尔有限公司保留所有权利。
Carminic acid is a natural colourant that can be obtained from the dried bodies of females of the Dactylopius coccus Costa insect species (cochineal). Carminic acid is the main pigment that can be extracted from the cochineal insect. Its main use is with cosmetics, foods and pharmaceutical applications and it can also have textile and plastic applications. The traditional extraction methods employed to obtain this dye involve several drawbacks, e.g. high extraction time, low selectivity and low extraction efficiency. Moreover, these conventional techniques need toxic solvents. In this work, new extraction methods have been studied in order to avoid the disadvantages mentioned above. Pressurised liquid extraction (PLE) and supercritical fluid extraction (SFE) techniques provide high selectivity and short extraction times. (C) 2011 Elsevier Ltd. All rights reserved.
