SPRINGER BRIEFS IN APPLIED SCIENCES AND TECHNOLOGY Felipe Richter Reis Reports on the Processing of Exotic Fruits 123 SpringerBriefs in Applied Sciences and Technology SpringerBriefs present concise summaries of cutting-edge research and practical applications across a wide spectrum of fields. Featuring compact volumes of 50–125 pages, the series covers a range of content from professional to academic. Typical publications can be: (cid:129) A timely report of state-of-the art methods (cid:129) Anintroductiontooramanualfortheapplicationofmathematicalorcomputer techniques (cid:129) A bridge between new research results, as published in journal articles (cid:129) A snapshot of a hot or emerging topic (cid:129) An in-depth case study (cid:129) Apresentation ofcore conceptsthatstudents mustunderstand inordertomake independent contributions SpringerBriefs are characterized by fast, global electronic dissemination, standard publishing contracts, standardized manuscript preparation and formatting guidelines, and expedited production schedules. On the one hand, SpringerBriefs in Applied Sciences and Technology are devoted to the publication of fundamentals and applications within the different classical engineering disciplines as well as in interdisciplinary fields that recently emerged between these areas. On the other hand, as the boundary separating fundamental research and applied technology is more and more dissolving, this series isparticularlyopentotrans-disciplinary topics between fundamentalscience and engineering.

Preface Exotic fruits are usually defined as fruits of distinctive sensory characteristics and limited market share, which makes industrial processing a suitable way to expand their commercialization. Industrial processing extends the exotic fruits’ shelf-life, which is originally of a few days, to several days or months, thus allowing com- mercetootherregions.Inthisbook,examplesofattemptstoextendtheshelf-lifeof exoticfruitsbymeansofdevelopingbeverages,jams,marmalades,driedfruits,ice creams,andotherproductsareprovided,alongwiththeimpactofprocessingonthe fruit’s nutritional features and the processing conditions used for achieving the product shelf-stability. In this sense, Chap. 1 brings an introduction containing conceptual aspects, previous reviews on related themes, and some information on the chemical characterization of exotic fruits. Chapter 2 is devoted to exotic fruit beverages, which was the theme with the highest number of studies in a search in scientific databases. Chapter 3 deals with exotic fruit jams and pulps, the former being an interesting option for developing countries since they do not need refrigeration and the latter being useful as ingredients of a wide range of products. Finally,Chap. 4 addressesother relevantproducts,viz. structuredexoticfruitsand dried exotic fruits, which received specific sections due to the high number of reports on these themes, along with ice creams, marmalades, minimally processed exotic fruits, and so on, thus covering all relevant exotic fruit products. Given the wide diversity of the Brazilian biome, many studies were collected from indexed scientific Brazilian journals, thus allowing the reader to be aware of the many unique exotic fruits native to here, which I believe to be a strength of the manuscript.

The shelf-life of exotic fruits is very short of about a few days; therefore, it is interesting to use processing techniques to increase their shelf-life for allowing their consumption during the whole year and in other regions.
