Food processing, preservation, and packaging is a highly interdisciplinary science. Various techniques and technologies have been developed to extend food shelf life, minimize the risk of contamination, protect the environment, and improve foods¿ functional, sensory, and nutritional properties. Some of the many benefits of food processing, preservation, and packaging include increased food safety, improved nutrition, longer shelf life, and increased economic opportunities. In addition, food processing and preservation help to reduce post-harvest losses. Developing novel food processing, preservation, and packaging technologies is critical to preserving food quality, improving sensory characteristics, and reducing losses. At present, there is a great emphasis on developing novel biobased and intelligent packaging technologies that are safe for food and reduce environmental pollution. This book provides a comprehensive overview of food processing and preservation packaging to tackle the challenges of food safety, nutritional security, and sustainability. Chapters address such topics as edible packaging materials, intelligent packaging materials, nanotechnology for enhancing the shelf life of food products, advanced food packaging systems, green materials for food packaging, antimicrobial packaging materials, food drying technologies, methods of food processing, food analysis using acoustic and thermal methods, food formulations, and functional foods. This volume is a useful resource for students, researchers, and food processing preservation professionals. It highlights advances in food processing and packaging systems to increase food quality and preserve food longer without generating waste.

First-generation ethanol plants did not have many operational challenges as the feedstocks (e.g., corn) used for fuel production are dense, stable, storable, and shippable commodity-type products with fewer conversion challenges. These feedstock properties led the first-generation large-scale biorefineries to grow exponentially. In the second-generation biofuels, the feedstocks used are agricultural and forest residues, dedicated energy crops, industrial wastes, and municipal solid waste. When the industry tested these feedstocks for biofuel production, they faced flowability, storage, transportation, and conversion issues. One way to overcome some of the feeding, handling, transportation, and variable moisture challenges is to densify the biomass. Pellet mills and briquette presses are commonly used to produce densified products. The densified products have uniform size, shape, higher bulk density, and better downstream conversion performance. Also, the densified products are aerobically stable and can be stored for longer durations without any loss in quality.This book's focus is on understanding how the densification process variables, biomass types and their blends, mechanical preprocessing, and thermal and chemical pretreatment methods impact the quality of the densified products produced for biofuel production. Finally, the book also explores the conversion performance of densified biomass for biofuel production.
