The objective of this work was the understanding of the internal pore structure creation of instant coffee. It includes the question which parameters are influencing the pore structure and mapping the applicable ranges. The influence of these structural parameters on the drying kinetics were investigated in experiment and modeling, finding the optimal approach to increase the drying kinetics. The reconstitution behavior of the dried powder structures was analyzed to link the process optimization to product quality aspects. The instant coffee was structured in a scraped surface heat exchanger and with different freezing methods, where samples were gassed with nitrogen and carbon dioxide. The amount of gassing, the total solids content, the coolant temperature, the scraping speed, temperature cycling and the freezing rate of the slurry during hardening were shown to influence the morphology of the samples, where total solids content, gassing, temperature cycling and freezing rate showed a dominant influence in the investigated range on structure parameters like open porosity, closed porosity and the median pore diameter, obtained after drying. It could be shown that the pore diameter has the biggest potential to improve drying and reconstitution kinetics

Spray-freeze-drying (SFD) is a synergistic drying technology that imbibes in it the merits of both spray drying and freeze-drying, whilst overcoming the limitations of these predecessor technologies. SFD produces uniquely powdered food and pharmaceutical products with porous microstructure and superior quality attributes. Owing to its atomization step and ultra-low-temperature operation, SFD is a competent drying technique for the production of valuable but sensitive bioactive components. Despite the costs and complexities involved, SFD has a competitive edge over the conventional drying techniques in providing distinctive product attributes. The applications of spray-freeze-drying in the area of food and bioproducts span across the product categories of instant food powders, dry flavors, active pharmaceutical ingredients, poorly water-soluble drugs, probiotics, proteins, enzymes and vaccines. Spray-Freeze-Drying of Foods and Bioproducts: Theory, Applications and Perspectives is the first exclusive title on this interesting drying technique. It provides a comprehensive understanding of the fundamentals of SFD and its food and pharmaceutical applications. The scope of this book, comprising 12 chapters, has been organizedunder four major headings: fundamentals of process-stages, applications with case-studies, recent advancements and the processing bottlenecks and solutions. Key Features Provides examples and case studies of nuances and intricacies associated with each stage of the spray-freeze-drying process Highlights the applications of spray-freeze-drying in the production of food products including soluble coffee, dairy powders, probiotics and flavors Serves as a ready-reckoner of characterization methods for spray-freeze-dried products Contains 200+ illustrations and tabulations The contents of this book are organized to cater to the knowledge needs of students, academicians, researchers and professionals in the food and pharmaceutical industry.

The Craft and Science of Coffee follows the coffee plant from its origins in East Africa to its current role as a global product that influences millions of lives though sustainable development, economics, and consumer desire. For most, coffee is a beloved beverage. However, for some it is also an object of scientifically study, and for others it is approached as a craft, both building on skills and experience. By combining the research and insights of the scientific community and expertise of the crafts people, this unique book brings readers into a sustained and inclusive conversation, one where academic and industrial thought leaders, coffee farmers, and baristas are quoted, each informing and enriching each other. This unusual approach guides the reader on a journey from coffee farmer to roaster, market analyst to barista, in a style that is both rigorous and experience based, universally relevant and personally engaging. From on-farming processes to consumer benefits, the reader is given a deeper appreciation and understanding of coffee's complexity and is invited to form their own educated opinions on the ever changing situation, including potential routes to further shape the coffee future in a responsible manner. Presents a novel synthesis of coffee research and real-world experience that aids understanding, appreciation, and potential action. Includes contributions from a multitude of experts who address complex subjects with a conversational approach. Provides expert discourse on the coffee calue chain, from agricultural and production practices, sustainability, post-harvest processing, and quality aspects to the economic analysis of the consumer value proposition. Engages with the key challenges of future coffee production and potential solutions.

Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.
