Advanced automation of a flow injectionanalysis system for quality control of olive oil through the use of a distributed expert system

摘要

A new methodology-based on he combination of flow injectionanalysis and a distributed expert system-is proposed for the on-line chemical quality control of olive oil.This knwoledge-based system is in charge out the flow injection determination of total acdity,peroxide value,and UV spectrophotometric measurements (K_323 and K_270),according to EU legislation.On the other hand,the expert system,apart from supervising the correct functioning of the system(devices,clogging,and analysis frequency,and so on),performs the definite classification of the analyzed oil by evaluating the oill quallity from the values yielded,according to previously established specifications.Satisfactory results have been obtained in the applicaton of this approach to differnt sampels of Spanish olive oil alogn the storage process.The adistributed expert system also allows for the remote control of the anlaysis process owing to the interconnection of the differetn nodes by means of a communication network.
