Quality of Fresh and Processed Foods


Book Description

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.




Minimally Processed Foods


Book Description

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 for Increased Quality and Consumption


Book Description

Food Processing for Increased Quality and Consumption, Volume 18 in the Handbook of Food Bioengineering series, offers an updated perspective on the novel technologies utilized in food processing. This resource highlights their impact on health, industry and food bioengineering, also emphasizing the newest aspects of investigated technologies and specific food products through recently developed processing methods. As processed foods are more frequently consumed, there is increased demand to produce foods that attract people based on individual preferences, such as taste, texture or nutritional value. This book provides advantageous tools that improve food quality, preservation and aesthetics. - Examines different frying techniques, dielectric defrosting, high pressure processing, and more - Provides techniques to improve the quality and sensory aspects of foods - Includes processing techniques for meat, fish, fruit, alcohol, yogurt and whey - Outlines techniques for fresh, cured and frozen foods - Presents processing methods to improve the nutritional value of foods




Fruit and Vegetable Processing


Book Description

Fruit and vegetables are both major food products in their own right and key ingredients in many processed foods. There has been growing research on their importance to health and techniques to preserve the nutritional and sensory qualities desired by consumers. This major collection summarises some of the key themes in this recent research.Part one looks at fruit, vegetables and health. There are chapters on the health benefits of increased fruit and vegetable consumption, antioxidants and improving the nutritional quality of processed fruits. Part two considers ways of managing safety and quality through the supply chain. A number of chapters discuss the production of fresh fruit and vegetables, looking at modelling, the use of HACCP systems and ways of maintaining postharvest quality. There are also two chapters on instrumentation for measuring quality. Two final chapters look at maintaining the safety and quality of processed fruit and vegetables. Part three reviews technologies to improve fruit and vegetable products. Two chapters consider how to extend the shelf-life of fruits and vegetables during cultivation. The following three chapters then consider how postharvest handling can improve quality, covering minimal processing, new modified atmosphere packaging techniques and the use of edible coatings. Two final chapters discuss two major recent technologies in processing fruit and vegetables: high pressure processing and the use of vacuum technology.With its distinguished editor and international team of contributors, Fruit and vegetable processing provides an authoritative review of key research on measuring and improving the quality of both fresh and processed fruits and vegetables. - Reviews recent research on improving the sensory, nutritional and functional qualities of fruit and vegetables, whether as fresh or processed products - Examines the importance of fruits and vegetables in processed foods and outlines techniques to preserve the nutritional and sensory qualities desired by consumers - Discusses two major technologies in processing fruits and vegetables: high pressure processing and the use of vacuum technology




Fresh-Cut Fruits and Vegetables


Book Description

Fresh-Cut Fruits and Vegetables: Technologies and Mechanisms for Safety Control covers conventional and emerging technologies in one single source to help industry professionals maintain and enhance nutritional and sensorial quality of fresh-cut fruits and vegetables from a quality and safety perspective. The book provides available literature on different approaches used in fresh-cut processing to ensure safety and quality. It discusses techniques with the aim of preserving quality and safety in sometimes unpredictable environments.

Ultra-processed foods, diet quality and human health


Book Description

The significance of industrial processing for the nature of food and the state of human health - and in particular the techniques and ingredients developed by modern food science and technology - is generally underestimated. This is evident in both national and international policies and strategies designed to improve populations' nutrition and health. Until recently it has also been neglected in epidemiological and experimental studies concerning diet, nutrition and health. This report seeks to assess the impact of ultra-processed food on diet quality and health, based on NOVA, a food classification system developed by researchers at the University of Sao Paulo, Brazil.
