Quality control methods and Total Quality Control in the food industry. Introduction. Quality control of food dates back many years, to when men started to use fire. Quality Control in the Food Industry. Quality control (QC) is a reactive process and aims to identify and rectify the defects in finished products. It can be achieved by identifying and eliminating sources of quality problems to ensure customer's requirements are continually met. Quality Control in the Food Industry, Volume 1 focuses on the general aspects of quality control in the food industry, emphasizing the controllable factors that affect the quality of the finished product, including the selection of raw materials, processing methods, packaging, storage, and distribution.

X-ray quality control food industry that are most commonly found at the end of the production line are used to identify defects before products are dispatched and sent to the retailer or distributor.

When used at one of these critical control points, the systems help provide quality assurance by preventing defects in final products.

It involves the inspection aspect of quality management and is typically the responsibility of a specific team tasked with testing products for defects.


The information they send to workers must also be modified by feedback from the staff. Well trained and informed staff are an essential element of the Quality Assurance approach.

The other main element of the quality assurance approach which ensures that the system works is to document in a simple way the procedures and responsibilities within a team of workers. Consider the problems faced by the bakery described previously: Problem 1 The use of wooden trays This problem was related to the use of trays by the distributor.

Who was responsible for arranging the contract with the distributor and specifying the use of wooden trays? A quality assurance system ensures that this link in the chain is discussed by the manager and staff and that proper controls and arrangements with the distributor are put into quality control food industry for example, plastic sheets on the wooden trays.

Processed Food Testing, Inspections and Audits

The producer needs to use the complaint information quality control food industry modify the process and prevent the complaint occurring again. The types of complaints should be recorded, sources of the problem identified within the factory or supply chain and control measures put into place.

Problem 2 The customer requiring special bread The internal business communication broke down and important information did not reach the production staff. Quality control food industry quality assurance system ensures that this communication is constantly operating and being improved.

Why is Quality Control Indispensable in the Food Industry?

Responsibility and authority are defined and written down. Problem 3 Tainted bread causing sickness The management had not identified and controlled the potential hazard that improper handling and storage of chemicals can cause.


The effective creation of a quality assurance system should include an assessment and development of methods to control or prevent hazards. Quality Assurance systems are not mysterious and need not be complex.

They simply require the business to agree what are the customers' needs and then ensure that staff have the skills, materials, and information needed to deliver the promises that are made A quality assurance system quality control food industry not be static but it should be continually modified and refined.

This requires an investment in training people to ensure that the quality assurance system controls the essential steps in the whole manufacturing and distribution process to satisfy customer needs. A range of problem solving techniques can be provided for quality control food industry workers to use when trouble arises during production.

These simple techniques are tried and tested. They involve problem identification, analysis of the cause, suggestions for solutions and implementation and feedback methods.

These techniques allow the operators more control over their work and allow problems to be prevented rather than solved. More advanced statistically-based methods can be used for sampling plans and process optimisation but these are beyond the scope of this book.

One of the main building blocks used for developing a quality assurance system is the 'Hazard Analysis Critical Control Point' system which is described in the next section. Safety is quality control food industry an option but it is an essential part of the planning, preparation and production of foods.

Any lack of consideration of safety can result in a serious threat to public health. Our inspectors and lab technicians follow detailed protocols that combine regulatory standards with our extensive know-how and your in-house specifications.
