Article Abstract

The packaged foods industry is growing more diverse and innovative almost by the day. Major companies around the world are entering the markets and are constantly developing new products. The fastest growing segment has been the diet sector.The calorie conscious consumers are increasingly becoming more sophisticated and demanding. They are making their purchasing decisions on the basis of the caloric declaration. This declared number of calories is based on the declared package net weight. No allowance is made for the overpack, which can be considerable.

Federal rules concerning calories are loose and most producers have policies that are stricter. These policies may result in very high scrap or rework costs. Those manufacturers who make policy decisions by statistical analysis of the product characteristics and parameters, will, without a doubt, have a competitive advantage. The inevitable conflict between minimum weight and maximum calories can only be resolved by careful analysis and control of the process.

This paper covers statistical methods used to establish policy and operating standards so that Process Control procedures will result in the minimum costs of production and reduce the risks of violating either the net weight or calorie limits.

The discussion deals with analysis at the development or formulation stage and continues through the scale-up stage to production. It proceeds with development of rules and procedures for routine operations. Statistical estimation of the costs of various policy alternatives is also discussed.
