ABSTRACT
Ochratoxin A (OTA) is a toxic secondary metabolite mainly produced by Aspergillus and Penicillium species, with strong renal toxicity, teratogenic, carcinogenic, mutagenic effect. Studies have shown that OTA is not only widely contaminated in food and feed crops, but also has been widely contaminated in Chinese herbal medicines such as spices, licorice and so on. In view of OTA's universality and harmfulness, this paper summarizes the flow visualization test strip, microsphere, electrochemical sensor, surface enhanced Raman spectroscopy technology in OTA rapid detection, which provides reference for the research and application of high throughout detection instrument miniaturization in order to achieve OTA quick detection and simple operation.
ABSTRACT
Natural plant pigment is rich in resources, with the features of natural color and environment friendly, which has a broad space for development and market prospects. In order to further develop and utilize of natural plant pigment, this paper mainly introduces the natural plant dyes in the domains of food, cosmetics and health care products on the historical development process and their application. In addition,this paper summarizes the application of representative natural plant pigment, dyes, and prospects the market of natural plant pigment, so as to provide reference for the development of natural plant pigment in the enlarged health industry of China.
