STATISTICAL QUALITY CONTROL CHARTS ON ATTRIBUTES IN FISH PROCESSING TECHNOLOGY.

Abstract

Apart from the use of statistical quality control chart for variables or attributes offood products in a food processing industry, the application of these charts for attributesof fishery products is explained. StatistJical quality control char~ for fractiondefectives is explained by noting defective fish sausages per shift from a sausageindustry while control chart for number of defectives is illustrated for number ofdefective fish cans in each hour of its production of a canning industry. C-chart isanother type of control chart which is explained here for number of defects per singlefish fillet sampled a1l random for every five minutes in a processing industry. TheseStatistical quality control charts help in the more economic use of resource, time andlabour than control charts for variables of products. Also control charts for attributesexhibit the quality history of finished products at different times of productionthereby minimising the risk of consumer rejection
