郑州市火棘果红色素的提取及理化特性研究

以郑州产火棘果为原料,经冲洗、干燥、粉碎后,用70%酸性乙醇浸提制得火棘红色素溶液,并对该色素的稳定性进行研究。旨在为郑州市区火棘资源的研究和功能性产品的开发提供依据。结果表明,该色素在酸性条件下对光、热、常用食品添加剂都比较稳定,是一种价廉易得、安全可靠、开发方便的天然植物色素。

Study on Extraction and Physicochemical Characters of Pyracanthafortuneana Red Pigment

In this paper the materials are Pyracantha fortuneana fruit, which were harvested from Zhengzhou. The materials were treated by rinsing, desiccating and crushing. Extracts the Pyracanthafortuneana red pigment with soaking the acidic edible 70% ethyl alcohol, and conducts the research to this pigment stability. It is for the purpose of provides the basis for Zhengzhou City Pyracanthafortuneana resource research and the development. The result indicated that, the pigment under acidic condition to light, heat, commonly used food additive are all quite stable, which is one kind of moderate price, safeis reliable, easy to operate natural plant pigment.
