role of quality control in food industry

Moreover, quality control practices in process, application of statistical methods for quality control and the adoption of Good Manufacture Practices (GMP) and Hazard Analysis and Critical Control Points (HACCP) denote that the company has a slightly broader approach that inspection, i.e., a more preventive approach control in the production process. The formal start of statistical process control occurred around 1924, when Shewhart developed and applied control charts at Bell Telephone Laboratories, a telephone company in the United States [1, 7, 13]. In the '50s, the quality control was employed in Japan, by an intensive use of statistical techniques. The programs commonly used in this area are Good Manufacturing Practices (GMP), Hazard Analysis and Critical Control Points (HACCP), British Retail Consortium (BRC) and Global Food Safety Initiative (GFSI), frequently found in the food industry, are obligatory by law, and others are implemented voluntarily by the food chain members [3]. Sigma (σ) is a letter of the Greek alphabet used by statisticians to measure the variance in any process. Such standards are documents containing technical specifications or specific criteria that will be used as a guide in order to ensure that products, processes and services are designed with quality [6]. These causes of variation do not cause appreciable variation in product quality; its elimination is impossible or anti-economical, and therefore, random causes are considered a natural part of the manufacturing process [8]. Food safety and quality assurance systems can take many forms: (1) private voluntary international quality assurance standards, such as ISO 9000; (2) national farm level assurance systems, such as Farm Assured British Pigs; and (3) proprietary quality assurance systems, such as those maintained by the large retail food chains in the U.K. Albeit with differing origins, quality assurance systems share two … The quality management system proposed by the Japanese model shows how basic features to the participation of all sectors and all company employees in the practice of quality control, constant education and training for all levels of the organization, circles activity of quality control, audits, use of basic and advanced statistical techniques and national campaigns to promote quality control. GMPs are an integral part of quality control- this is where QWerks could do the most good for your company. Continuous improvement occurs the more times the PDCA cycle is run, and optimizes the execution of processes, enables cost reduction and increases productivity. The boundaries must be recalculated and a new chart of amplitude must be drawn (Figure 6). In a survey conducted in UK food industry, revealed that while there are large differences in process types, quality priorities and key measures among different sub-sectors of the industry, the use of control charts was broadly similar. On the production line, the procedures and steps for handling the product have to be documented, in order to ensure the standardization of safety practices. Open Access is an initiative that aims to make scientific research freely available to all. Through standardization it is achieved greater standardization of products, improved productivity and product quality, cost reduction, simplification and optimization of production processes, increase the technical capacity of operators of process, greater job security, reduction of inventory levels of raw materials and inputs, reducing the preparation time of the machines and self-management by the workers. Moreover, this global scenario represents some opportunities for the companies to act in the new markets. Thus, it is important to highlight these stages of evolution of quality that began with the inspection of products, have passed the statistical quality control, the stage of quality systemic management until the strategic quality management. According Grigg, the initiatives of training of new graduates entering the industry in the principles of quality assurance and statistical methods and training the existing workforce and management in applying statistical control procedures to processes will make this methods more use of it than they are [9, 10]. The issue of food safety has been in the public eye as never before. Garvin, a scholar of quality management, highlights four ages or stages through which the way to manage the quality has evolving over time in the U.S [1]. The industrial statistic includes descriptive statistics, process capability analysis, measurement system analysis, basic graphics as histogram, scatter, box-plot, Pareto diagram, cause and effect, design of experiments, linear regression and correlation, multiple regression, hypothesis testing, confidence intervals, analysis of variance, analysis of process capability, among other tools [8].
