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. The book describes the principles of quality control and some important concepts such as sensory assessment and statistical approaches, along with food standards and health problems in quality control. This volume is organized into six chapters and begins with an overview of the application, organization, related problems, techniques, and prospects of quality control. The next chapters focus on the chemical and microbiological aspects of health problems in quality control; fundamental concepts in statistics as applied to quality control from sampling to the estimation of ingredients; and taste testing as an approach to quality control of processed foods. The book concludes by considering the importance, limitations, and problems associated with food standards, with special reference to their international aspects. This book will be of interest to food scientists and technologists, managers in the food industry, and students.
