Quality is a composite term encompassing many characteristics of foods. These include color, aroma, texture, general nutrition, shelf-life, stability, and possible presence of undesirable constituents. Obviously deterioration of quality may lead to changes in the attributes that characterize the food in its fresh or freshly processed state. In addition, quality enhancement of products may be carried out using appropriate processing techniques. Interaction of different components present with one another could have a profound effect on sensory quality of products. Meanwhile, presence of extraneous matter such as pesticides and debris may also contribute to a compromise in the quality of foods. In addition, processing often brings about changes in many attributes of food including its nutritional value. Thus, examination of process-induced changes in food products is important. In this book, a cursory account of quality attributes of fresh and processed foods is provided. The book is of interest to food scientists, nutritionists and biochemists in academia, government and industry.

Color is a critical measure of quality in foods and beverages. Researchers and technical personnel in quality assurance and product development need appropriate objective methods for measuring color. This book contains chapters by scientists from throughout the world with expertise on the pigment and color stability of many different commodities. While a broad range of foods are represented, there is particular emphasis on fruits and vegetables and beverages. There is heightened interest in the natural food pigments today because of their health benefits and roles in reducing the risk of coronary heart disease, cancer and other diseases. However, research on the health benefits of natural colorants is not the subject of this book, rather the focus is on color quality- how it can be optimized and how it is appropriately measured. The book opens with a section on color measurement covering the basic principles and practical aspects of color measurement. Sixteen chapters are devoted to fruits, vegetables and beverages. The perspective of plant breeders is given along with that of academic and industrial scientists. Food colorants are given intense scrutiny when it comes to regulation, and there is considerable variation from country to country with respect to both basic principles and specific rules for use and labeling of colorants. The six chapters in the final section on regulatory aspects give a very comprehensive update on colorant regulations in the USA, Europe, Central and South America and Asia. The viewpoint from regulatory agencies is given along with that from manufacturers and users of food colorants. This section provides a very clear picture of food colorant regulations at the present time. Much of this information is also relevant to other food ingredients. The book contains a number of color plates that were selected to make for a clearer presentation of the author's concepts.

Attempts to provide safer and higher quality fresh and minimally processed produce have given rise to a wide variety of decontamination methods, each of which have been extensively researched in recent years. Decontamination of Fresh and Minimally Processed Produce is the first book to provide a systematic view of the different types of decontaminants for fresh and minimally processed produce. By describing the different effects – microbiological, sensory, nutritional and toxicological – of decontamination treatments, a team of internationally respected authors reveals not only the impact of decontaminants on food safety, but also on microbial spoilage, vegetable physiology, sensory quality, nutritional and phytochemical content and shelf-life. Regulatory and toxicological issues are also addressed. The book first examines how produce becomes contaminated, the surface characteristics of produce related to bacterial attachment, biofilm formation and resistance, and sublethal damage and its implications for decontamination. After reviewing how produce is washed and minimally processed, the various decontamination methods are then explored in depth, in terms of definition, generation devices, microbial inactivation mechanisms, and effects on food safety. Decontaminants covered include: chlorine, electrolyzed oxidizing water, chlorine dioxide, ozone, hydrogen peroxide, peroxyacetic acid, essential oils and edible films and coatings. Other decontamination methods addressed are biological strategies (bacteriophages, protective cultures, bacteriocins and quorum sensing) and physical methods (mild heat, continuous UV light, ionizing radiation) and various combinations of these methods through hurdle technology. The book concludes with descriptions of post-decontamination methods related to storage, such as modified atmosphere packaging, the cold chain, and modeling tools for predicting microbial growth and inactivation. The many methods and effects of decontamination are detailed, enabling industry professionals to understand the available state-of-the-art methods and select the most suitable approach for their purposes. The book serves as a compendium of information for food researchers and students of pre- and postharvest technology, food microbiology and food technology in general. The structure of the book allows easy comparisons among methods, and searching information by microorganism, produce, and quality traits.

The safety and efficacy of minimal food processing depends on the use of novel preservation technologies. This book first examines what is meant by minimally processed foods, including fresh-cut, cooked-chilled, and part-baked products. Next explored are the technologies or methods to produce quality products in terms of safety and nutrition, including: edible coating, natural preservatives (i.e., antimicrobial, flavour enhancer, anti-browning), advanced packaging (active, antimicrobial, and modified or controlled atmosphere), and selected non-thermal techniques (high pressure, pulsed electric field, ultrasound, light). Preservation of food is crucial to achieving a secure and safe global food supply with the desired sensory quality. In addition, the increasing consumer demand for safe, ready-to-serve, ready-to-eat-and-cook products with minimal chemical preservatives has raised expectations. However, foods deemed minimally processed, such as fresh-cut fruits and vegetables, cooked-chilled, and half-baked foods, are delicate products that need special care in preparation, processing, storage, and handling. As a result, new technologies to develop minimally processed foods have aggressively advanced. Minimally Processed Foods: Technologies for Safety, Quality, and Convenience explores both the definition of minimally processed foods and the methods and technologies used to achieve the safety and nutritional value consumers demand.

Food processing is expected to affect content, activity and bioavailability of nutrients; the health-promoting capacity of food products depends on their processing history. Traditional technologies, such as the use of antimicrobials and thermal processing, are efficient in increasing nutritional value to an extent, though they may not be effective at addressing food safety, particularly when it comes to maintaining the food's molecular structure. Modern food processing plants improve the quality of life for people with allergies, diabetics, and others who cannot consume some common food elements. Food processing can also add extra nutrients, such as vitamins. Processed foods are often less susceptible to early spoilage than fresh foods and are better suited for long-distance transportation from the source to the consumer. However, food processing can also decrease the nutritional value of foods and introduce hazards not encountered with naturally occurring products. Processed foods often include food additives, such as flavourings and texture-enhancing agents, which may have little or no nutritive value, and may in fact be unhealthy. This book deals with the subject of food processing in a unique way, providing an overview not only of current techniques in food processing and preservation (i.e., dairy, meat, cereal, vegetables, fruits and juice processing, etc.) but also the health and safety aspects: food technologies that improve nutritional quality of foods, functional foods, and nanotechnology in the food and agriculture industry. The text also looks into the future by defining current bottlenecks and future research goals. This work will serve as a ready reference for the subject matter to students and researchers alike.

The first edition of Minimally Processed and Refrigerated Fruits and Vegetables, edited by Robert C. Wiley and Fatih Yildiz, was published in 1994. At the time of publication, this was a new concept and was well-received by the scientific community. Minimally processed foods are whole plant tissues (the identity of the plant tissue is recognized by consumers), which may contain active enzymes, live tissues, and plant cells. These are some of the basics for the healthy food design. The overall function of these foods is to provide convenient (ready-to-serve, ready-to cook, free of any pesticides and contaminants),like-fresh products for food service and retail consumers. Minimally Processed and Refrigerated Foods (MPR) have been popular in many countries. The following are some of the advantages offered by MPR produce foods: 1. Ease of portion control in the food service industry 2. Lower transportation cost (all inedible portions of the produce are removed prior to transportation) 3. No waste is generated at the point of consumption 4. Utilization and recycling of the waste is much easier 5. Value-added new fruit and vegetable products and meal development is possible and easy 6. No requirement is needed for phytosanitary control during trade 7-No glycation end products formation during processing, 8.Degree of food processing is minimized for optimal health of human, the processing plant for MPR produce, which is not addressed in any other books on this topic, will be described in this second edition. Also, comparison of minimal processing technologies with other technologies was explained in the first publication and will be updated in this second edition. During the last 200 years the purpose of food processing was a-safety(sterilization, Pasteurization,1804 Nicholas Apert,Pasteur 1867), and b-prevention of deficiency diseases(Enrichments),but MPR foods provides a two new dimensions to food processing ; a-Prevention of chronic diseases(bioactive compounds) and b-Optimum health (functional foods,Superfoods,Neutraceuticals, and Medical foods) for human.
