Recent Developments in High Pressure Processing of Foods


Book Description

Features a Foreword by Dr. Dietrich Knorr. Fruit processing and preservation technologies must ensure fresh-like characteristics in foods while providing an acceptable and convenient shelf life, as well as assuring safety and nutritional value. Processing technologies include a wide range of methodologies to inactivate microorganisms, improve quality and stability, and preserve and minimize changes of fresh-like characteristics in fruit. High pressure as a food preservation technique inactivates microorganisms at room temperature or lower; thus, sensory and nutritional characteristics can be maintained. In recent years, a significant increase in the number of scientific papers in literature demonstrating novel and diversified uses of high pressure processing indicates it to be highly emerging technology. The effect of high pressure technology on the quality and safety of foods will be discussed. Selected practical examples in fruits and vegetables, dairy and meat industries using high pressure will be presented and discussed. A brief account of the challenges in adopting this technology for industrial development will also be included.

Book Description

High pressure processing is a fast-growing food processing technology and opens the door to nearly-fresh products that retain their sensorial and nutritional qualities. High Pressure Processing of Fruit and Vegetable Products reviews and summarizes the latest advances in novel high-pressure processing techniques for preserving fruits, fruit juices, and their mixtures. It contains basic information on the relation of high-process treatment parameters with the safety and quality of fruit and vegetable juices/products. The book focuses on product quality parameters, nutritional value, bio-active health components, and microbial safety and stability. The main aim of this book is to summarize the advances in the utilization of modern high pressure pasteurization (HPP) treatment to preserve and stabilize fruit and vegetable products. HPP technology is related to the product quality parameters, the content of nutritional and health active components, and the microbial safety and subsequent shelf life. One chapter of this book is devoted to industrial equipment available; other chapters deal with examples of commercial fruit and vegetable products. Another chapter of this book is dedicated to packaging, as packaging of food before HPP is mandatory in this technology.
