RESEARCH ON THE URBAN ARCHITECTURAL HERITAGE FOOD COMPOUND METHOD BASED ON RSM - TAKING THE ANCIENT CITY OF QUANZHOU AS AN EXAMPLE

Recently, information technology (IT) and digital media have been widely applied as a new era rises, and RSM playing a more and more important role in many scientific fields has become a medium presenting design concept and operating mode. Taking the food distribution method of the ancient city of Quanzhou as an example. On the basis of two factors of two compound bacterium suppression experiments, this paper aims to firstly extract the purple potato anthocyanins by the assistance of Response Surface Analysis(RSA) and the Optimization of Ultrasonic. Then to purify the purple potato anthocyanins using the AB-8 macroporous resin and the thin layer chromatography(TLC). It helps to shorten extracting time and to improve the extraction rate. In the meanwhile, this paper also explores the influence on bacteriostatic action on purple potato anthocyanins with the External conditions of PH, temperature and ultraviolet light. Taking the extraction and purification of anthocyanins as natural antimicrobial substances and distributing with the preservative sodium benzoate and potassium sorbate to explore the bacteriostatic action towards Staphylococcus aureus, Escherichia coli, Bacillus subtilis, white mildew and Candida albicans. Among them, we are able to choose optimal antibacterial compound the bacteria dispensing. It is approved that the purple potato anthocyanins is not only a kind of natural colorants, but also is of the bacteriostasis function.
