Ă propos de ce livre
Food Waste Recovery: Processing Technologies and Industrial Techniques acts as a guide to recover valuable components of food by-products and recycle them inside the food chain, in an economic and sustainable way. The book investigates all the relevant recovery issues and compares different techniques to help you advance your research and develop new applications. Strong coverage of the different technologies is included, while keeping a balance between the characteristics of current conventional and emerging technologies. This is an essential reference for research outcomes.
- Presents a holistic methodology (the so-called "5-Stages Universal Recovery Process") and a general approach (the so-called "Universal Recovery Strategy") to ensure optimized management of the available technologies and recapture of different high added-value compounds from any waste source
- Includes characteristics, safety and cost issues of conventional and emerging technologies, the benefits of their application in industry, and commercialized applications of real market products
- Demonstrates all aspects of the recovery process such as preservation of the substrate, yield optimization, preservation of functionality of the target compounds during processing, and more

Abstract
Macroscopic pretreatment of food waste aims at the preparation of the food matrix for subsequent processing and recovery steps. The preparatory steps involve the adjustment of the phase content and properties (water, solid, fats content), the moderation of enzyme activity as well as prevention and control of any microbial growth (Galanakis, 2012; Galanakis et al., 2010a). In recent times, several emerging technologies have been researched, developed, and/or adapted from other fields for drying, sterilization, enzyme inactivation, and enhancing mass transfer in food and biomaterials. This chapter focuses on these upcoming technologies with potential applications to food waste recovery and includes foam-mat drying, electro-osmotic drying, radio-frequency drying, cold plasma technology, and high-pressure processing. The content lays emphasis on discussing the successful applications and identification of future prospects, from both a technology and an economic point of view.

9.1. Introduction
The basic idea of macroscopic pretreatment is to prepare the food matrix for downstream processing. The pretreatment steps aim at one of the following:
1. adjustment of the different phases of the matrix,
2. moderation of enzyme activity,
3. protection from microbial growth,
4. concentration of the waste for economic extraction,
5. facilitation of storage of the waste substrate until further processin...
