The ISO 22000 standards specifies the requirements to a safety management system that combines elements of food management system to ISO 9001 templates, as already said, and interactive communication, since communication along the supply chain is essential to ensure that all relevant safety hazards of food are identified and controlled. These causes require prompt corrective action, in order to eliminate them. Collect m samples of size n. In general m = 20 or 25 at least. Notify the local council with details of their food business 2. Establish the boundaries of the amplitude chart (Chart of R): The values of D4 and D3 are tabulated [7, 8]. © 2013 The Author(s). A business owner must: 1. The manufacturing control is exercised by the manufacturer during the industrialization process. The quality management applies systems and tools that are intended to assist the implementation of quality-oriented way to improve the product and the process, increasing the levels of quality business and ensuring customer's satisfaction. In order to implement activities that will be used to achieve consistent products within specifications, you must first define those specifications. Concerned to improve their production processes, automate production lines and constantly launch new products into the market. Later, the year of 1931 was a milestone in the quality movement and the beginning of the second phase, the Statistical Quality Control. Organizations that employ the Six Sigma method aim to achieve 3.4 defects per million on manufactured products. Also here the construction of a chart for attributes will be exemplified. The videos support the FDA's Retail Food Safety Initiative, which seeks to strengthen the retail and foodservice industry's active managerial control of foodborne illness risk factors. If the process is under control, samples that present variability corresponding to samples taken from a normal population, i.e., the variability is attributable only to product that is the sample. So for its strong integrator character, the success of the implementation depends largely on the acceptance of the various links in the supply chain. The other type of variability is caused by remarkable and special causes that arise sporadically due to a particular situation which causes the process to behave in a completely different way than usual, which can result in a displacement of the quality level. Several scholars of quality management are unanimous in emphasizing that the companies in general, and also the food industry, through its organizational structure, the policies adopted, the focus given to the business and the practice of quality control, demonstrate a certain degree of maturity in how to manage quality. 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]. A single sampling plan by attributes is defined by two parameters: sample size and acceptance number. Quality control is applicable throughout the entire food system. Quality Management: Important Aspects for the Food Industry, Food Industry, Innocenzo Muzzalupo, IntechOpen, DOI: 10.5772/53162. Measure: to establish valid and reliable measurements for information and data. What is the role of inspection in food safety and quality? Later in 2002, FDA forms Food GMP Modernization Working Group and announces effort to modernize food GMP´s [4]. As there is always a possibility of failure, it is essential to provide corrective measures in order to ensure the process return into a controlled situation. However, the excessive emphasis on statistical techniques led to some problems, such as low interest shown by senior management of companies, by the quality control, which remained a movement of ground and plant, i.e., to engineers and workers [16]. The purpose of this topic is to describe some tools, techniques and systems that have been more widely used in quality management in the food industry. This is the clearest indication of lack of control of a process, which requires an immediate investigation of the cause of variation. They also work in the factory or processing areas, collecting samples for performance evaluation processes, unit operations, sanitary conditions or levels, verifying compliance with the requirements of food safety and all other operating specifications. More generally, the program focuses on defect prevention, reduction of cycle times and cost savings. Available from: The Olive Cultivation, Table Olive and Olive Oil Industry in Italy, Evolution of the quality management: A brief history, Tasks quality of the sector in the food industry, Methodologies in support of the quality management in the food industry, Department of Food Science, University Federal of Minas Gerais, Belo Horizonte, Brazil. To analyze the behavior points on the graph, and verify that the process is in statistical control. The inspection process is to analyze or examine units of a product in order to verify with its quality characteristics are in accordance with technical or contractual specifications. The quality control personnel must interact cooperatively with the personnel of the standards and inspection agencies to ensure that the official food law is understood and met. Xi is the number of defective items in the “i” sample. Check if the control state reached is appropriate to the process. And in terms of quality control there was difficulty to unify standards that ensure that a product had been manufactured under quality criteria, after several trials, in 1989, was published the standard ISO 9000. STATISTICAL QUALITY CONTROL TECHNIQUE IN FOOD AND BEVERAGE ... 2.4 The Role of Statistic in Quality ... delivery services and a host of other firms in the service industry.Quality management (QM) is the commonly used term for stressing quality within an organization. Built by scientists, for scientists. Another assignment of quality control includes reviewing and responding to consumer complaints. 1 Quality Control In Food And Dairy Industries The Quality control of food has a significant role in assuming a high quality, safe and nutritious food supply for the public, for their good health and for the economic benefits derived from trade of safe and high quality food. The Statistical Quality Control uses statistical tools to control a product or process. Therefore, in the sampling inspection an absolute conclusion about the quality of the lot will never be achieved, there is always a risk rate inherent in the sampling plan and dependent on its discriminatory power. Food is basic for life. Certainly, quality is a key factor for the food industry acts in a market increasingly globalized. These samples, known as rational subgroup should be taken when one believes that the process is under control and the operating conditions kept as uniform as possible. Internal and external audits are recommended for periodic maintenance and continuous improvement of the system [5]. 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. HACCP is a system based on prevention of hazards to the industry to produce safe food to consumers. There are two types of quality control charts: control charts for variables and control charts for attributes, which will be described below. Health Canada establishes policies and standards governing the safety and nutritional quality of all food sold in Canada, and carries out foodborne disease surveillance for early detection and warning.. This phase had a preventive approach, centered on the monitoring and control of process variables that could influence in the final product quality through the development of statistical tools for sampling and process control. Moreover, it also implies that this distribution remains stable, i.e., that its two parameters, medium (μ) and standard deviation (σ), remain constant, which is verified by extracting a sequence of samples. Certainly, with the advent of globalization, the market has become more competitive, because it has opened the opportunity for new competitors. Thereafter preventive measures are described and identified the Critical Control Points (CCPs). Likewise, the product control only by laboratory analysis is a feature of this stage. It should also develop, conduct and assist in an organized program, training of supervisors, operators and workers in general, into specific concepts of quality. The strategic approach is an extension of its predecessors, but with a more proactive approach. The goal is to maintain the quality of the product satisfactorily uniform, preventing the production of items outside specification. A Control Chart (Figure 2) consists of a Central Line (CL), is a pair of control limits: one above Upper Control Limit (UCL) and one below, Lower Control Limit (LCL), and characteristic values marked on the graph. Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too. Further, because of its extensive scientific and technical resources and experience with these issues, the food industry can make important contributions towards their understanding and resolution.

Analyzing the Figure 5, it can be seen that point 23 is above the UCL and therefore should be eliminated. From these assumptions, this chapter talked about the important aspects and also specific to quality management in the food industry. Aiming to harmonize the international level, the various guidelines related to food safety systems, it was developed the ISO 22000:2005 - Food Safety Management systems - Requirements for any organization in the food chain. Finally, it is worth noting that the Codex Alimentarius recommends the use of the ISO 2859 series relating to the procedures for sampling by attributes and the ISO 3951 series for the procedures for sampling by variables [14]. no stops or apparent defects. The 6-Sigma focuses on quality improvement (eg, waste reduction) to help organizations produce better, faster and more economical. The food industry use control charts in different ways depending upon their level of maturity in statistical thinking [15]. Note that for control of the packaging process of cuts of poultry, it chart has to be placed without padding, only with the UCL, CL and LCL, so that operators or responsible for quality control of packaging can monitor the process. The TQC ideas developed by the Japanese were broadcast around the world, being this model capable of being deployed in companies of various sectors, with appropriate adjustments to the corporate culture. Also can happened of points of the chart represent a trend, which consists of a continuous motion of the points of the control chart in one direction (ascending or descending). Suppose a manufacturer industry of biscuits decides to build a control chart p to visually check whether the product color after baking, was established as a standard for quality control. It is estimated that each year foodborne disease causes approximately 76 million illnesses, 325,000 hospitalizations and 5,000 deaths in the U.S., and 2,366,000 cases, 21,138 hospitalizations and 718 deaths in England and Wales [2]. Ensure the business complies with the Food Standards Code 3. Variability in process may be classified into two types: the variability caused by random or common cause, which are inherent in the process and will be present even considered that this process is fully standardized. Thus, faced with so many responsibilities, it remains to note that the dynamics of intervention and performance of those who are responsible for the quality department is paramount to the success of the food industry and customer satisfaction. In this stage the quality control of products was limited to a focus on corrective inspection, i.e., was a way to check the uniformity of the final product by separating the non-conforming products. The book may also serve as a guidebook to other industries that are initiating or reviewing their quality control procedures. The 6-Sigma program involves the application of statistical methods to business processes, guided by the goal of eliminating defects. After the HACCP plan drawn up, it is validation occur through discussions among team members [5]. The requirements of the series represented the consensus of different countries of the world. Some examples of control charts are to yield a formulation, to verify the volume of a drink during their bottling, the soluble solids of a sweet after its cooking and the time to deliver a product to the customer. The issue of food safety has been in the public eye as never before. These techniques can be developed for specific purposes within the production process, to product development or troubleshooting and optimization standards. The adoption of the Six Sigma methodology as a quality program in all agribusiness chain in general is still new, but it is important to highlight the potential of this method for improving the quality of food products and reduce production costs. If necessary, recalculate the chart boundaries after the abandonment of the points there are out of control. The methods, procedures and selection of instruments used to measure quality attributes of products and processes are the responsibility of the department of quality control. The sampling rate by attributes consists in classifying units of a product just as acceptable or unacceptable based on the presence or absence of a particular feature in each unit qualitative inspected. 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. With all that, the purpose of this chapter is to describe the potential use of quality tools in food companies. If so, adopt the current control chart. The two charts should be employed simultaneously. In practice, the parameters average μ and standard deviation σ are unknown and must be estimated from sample data. It should also watch the production department in its efforts to increase revenues, reduce losses and improve efficiency of operations. As in the entire production process variability occurs, Chart Control or Control Chart, or Map Control, aims to monitor these changes in processes, as well as to evaluate the stability of this process and eliminate or control the causes of variations. With this, the company increases operational efficiency reduces costs, improves quality, increases customer satisfaction and increases profitability [18, 19]. It is clear that this action will depend mainly on the quality of their own products and services offered. The basic objective of QC is to control variation to within a tolerable level by taking corrective actions. The new sanitary requirements and quality requirements dictated by the main international markets, led since 1991, to the deployment experimental stage of the HACCP. The concept of 6-Sigma system was developed by Motorola in the mid 80´s. A control of raw materials should be developed with suppliers, not only in the laboratory, but in a gradual and continuous improvement work, where food security is split with suppliers. In 1954 JUSE invited the engineer Juran, one of the masters of quality management, to deliver seminars to senior management. The quality control personnel works in different laboratories performing physical, chemical, microbiological and sensory properties of raw materials, ingredients, packaging materials and finished products. Finally, quality management has been incorporated within the strategic scope of organizations, this phase called Strategic Management of Quality. The standard has a similar format to the standard of ISO 9001 Quality Management. Also running records should be implemented as evidence that the job was well done. These are divided into Standard Process Technician (SPT) and Operational Procedure (OP). Foodborne disease has an enormous public health impact, as well as significant social and economic consequences. Chart p (proportion of defective products in the sample). While the movement occurred in Japan by TQC, in Europe there was a movement around an organizational structure whose purpose was to develop standards for manufacturing, trade and communication in European countries for the increased levels of quality of activities. Description. By Divine Nkonyam Akumo, Heidi Riedel and Iryna Semtanska, By Catherine Marie Breton, Peter Warnock and André Jean Berville. This challenge relates to the need to create greater consumer loyalty to products and services, greater suitability of the product to the consumer’s needs and greater concern about the social impact of the company. The competitiveness of a company can be seen as a reflection of the strategies adopted as a means to adapt to the prevailing standards of competition in the markets in which the organization operates. Analyzing the Figure 4, it can be seen that all points present within normal behavior. Control charts for variables are named due to the fact that the quality characteristic being analyzed is expressed by a number on a continuous scale measures. Draw lines to represent full UCL, CL and LCL (Figure 7). For this, the HACCP system combines technical information updated with detailed procedures to evaluate and monitor the flow of food into an industry. 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. Repeat this procedure until the control state is reached. Other barriers may arise in terms of local practices and investment cost. Besides the methods mentioned, there are others that could be employed by companies. Draw the control limits. The sections were collected when the machine was operating within normal procedure, i.e. 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. The Codex Alimentarius reflects an international consensus regarding the requirements for protection of human health in relation to the risks of foodborne illness. If necessary, recalculate the chart boundaries after the abandonment of the points there are out of control. It represented a vision of market-oriented management, i.e., with a view of opportunities before the competition and customer satisfaction, where market research has become more important for evaluating the market needs and how the competition stands. The HACCP involves a complete analysis of the dangers in the systems of production, handling, processing and consumption of a food product. Consequently, differences between an observed value X and the average μ, greater than ± 3σ are separated, three times to every 1000 observations, and therefore, the range of variability "normal" in the process under control is μ-3σ and μ+3 σ (Figure 3). 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]. Some typical situations in process out of control occur when can be seen points outside the control limits. The DMAIC can be resumed as follows: Define: define problems and situations to be improved, including the goals of the activities, as they will be the company's strategic objectives. According to the Food and Agriculture Organization of the United Nations, the food industry bears the responsibility of meeting food quality and safety regulatory requirements. The following hypothesis test is linked to inspection for acceptance: Being “p” the proportion of defectives that the process produces. By employing quality control measures, food industry companies can ensure that uniform products of the same quality are produced. More specifically, ISO 9001 deals with the requirements of the quality management system for an organization to produce compliant products and get customer satisfaction. Calculate the amplitude of each sample Ri, Calculate the average amplitude of the sample R. Thus the value of R (average amplitude) is R = 1,93. Moreover, the gradual and continuous improvements add value to the project and ensure customer satisfaction. Now it is necessary to build the chart of average (x). The study initially intends to contextualize the quality management in the food industry and the activities related to the quality function. Within the rules of the certification ISO 9001, there are specific requirements regarding the responsibility and involvement of management with the quality system, requirements for preparing and controlling of the documentation, for the critical analysis of contracts and selection of suppliers, to traceability and processes control, for measurement, for inspection and testing, analysis of nonconformities and for continuous improvement, for audits and training.
