The Harvest and Post-Harvest Management Practices' Impact On
Chapter The Harvest and Post-Harvest Management Practices’ Impact on Coffee Quality Mesfin Haile and Won Hee Kang Abstract Coffee is one of the most important agricultural commodities in the world. The coffee quality is associated with pre-harvest and post-harvest management activi- ties. Each step starting from selecting the best coffee variety for plantation until the final coffee drink preparation determines the cupping quality. The overall coffee quality influenced by the factors which involve in changes the physicochemical properties and sensorial attributes, including the post-harvest operations. The post- harvest processing activities contribute about 60% of the quality of green coffee beans. The post-harvest operations include pulping, processing, drying, hulling, cleaning, sorting, grading, storage, roasting, grinding, and cupping. This chapter comprises the harvest and post-harvest operations of coffee and their impacts on coffee quality. Keywords: digestive bioprocessing, coffee cherry, caramelization, Maillard reaction, speciality coffee 1. Introduction Coffee trees are widely grown in tropical and subtropical regions of Africa, Southeast Asia, and South America [1]. The world annual coffee production esti- mated 158.6 million 60-kg bags as of 2017/2018, up from 148.6 million 60-kg bags in 2014/2015. South America, Asia and Oceania, Mexico and Central America, and Africa produced as presented, respectively, 81.5, 47.7, 21.7, and 17.8 million 60-kg bags of coffee.

But we may have a money saving solution for you. David Gregg, senior editor of BehindTheBuy.com, visited The Early Show with a flavor and cost comparison of the latest single-serve home coffee machines and travel mugs for your java drinking on the go. Gregg says the machines he cites deliver a coffee shop-worthy brew while saving you money in the long run. PRIMARY REASONS PEOPLE GO TO COFFEEHOUSES: -Always Fresh -Favorite Flavor/Brew/Variety -Convenient/Instant Gratification -Consistent in quality of product PRIMARY REASONS PEOPLE LIKE SINGLE-SERVE COFFEEMAKERS OVER CARAFE- BASED MACHINES AND/OR GOING TO A COFFEEHOUSE: -Always Fresh -- can't get stale or acidic by sitting in a pot like carafe-based machines -Simple to Use/Convenient/Instant Gratification -Variety/Always choose your favorite brew -Cost Less Per Serving Compared to a Coffee House -Consistent quality--Single serve machines are computer controlled therefore they deliver just the right mixture of all of the variables (exact temperature of water, controlled pressure and volume of water to maximize flavor extraction, perfectly premeasured portions, built in filters) that are needed to deliver a good tasting beverage. -More Options than Carafe Based Machines (not everyone in the office or family drinks decaf, caffeinated, flavored coffee).

Coffee Flavor and Flavor Attributes That Drive Consumer Liking for These Novel Products
beverages Review Coffee Flavor: A Review Denis Richard Seninde and Edgar Chambers IV * Center for Sensory Analysis and Consumer Behavior, Kansas State University, Manhattan, KS 66502, USA; [email protected] * Correspondence: [email protected] Received: 1 June 2020; Accepted: 3 July 2020; Published: 8 July 2020 Abstract: Flavor continues to be a driving force for coffee’s continued growth in the beverage market today. Studies have identified the sensory aspects and volatile and non-volatile compounds that characterize the flavor of different coffees. This review discusses aspects that influence coffee drinking and aspects such as environment, processing, and preparation that influence flavor. This summary of research studies employed sensory analysis (either descriptive and discrimination testing and or consumer testing) and chemical analysis to determine the impact aspects on coffee flavor. Keywords: coffee flavor; processing; preparation; emotion; environment; consumer acceptance 1. Introduction The coffee market is currently worth USD 15.1 billion and growing. This market is mainly comprised of roasted, instant, and ready-to-drink (RTD) coffee [1]. The flavor of a roasted coffee brew is influenced by factors such as the geographical location of origin, variety, climatic factors, processing methods, roasting process, and preparation methods [2–10]. The differences in sensory properties can, in turn, affect consumers’ preferences for and emotions or attitudes toward coffee drinking [11]. 1.1. Motivations for Drinking Coffee As indicated by Phan [12], the motivations for drinking coffee can be grouped under 17 constructs: liking, habits, need and hunger, health, convenience, pleasure, traditional eating, natural concerns, sociability, price, visual appeal, weight control, affect regulation, social norms, social image [13], choice and variety seeking [12,14,15]. -

Carbon Footprint of Different Coffee Brewing Methods Matteo Cibelli, Alessio Cimini, Mauro Moresi*

ISBN 978-88-95608-85-3; ISSN 2283-9216 Carbon Footprint of Different Coffee Brewing Methods Matteo Cibelli, Alessio Cimini, Mauro Moresi* Department for Innovation in the Biological, Agrofood and Forestry Systems, University of Tuscia, Viterbo, Italy [email protected] The aim of this work was to assess which coffee brewing method was the most environmentally friendly one among a 3-cup induction Moka pot, and two single-serving coffee machines. To this end, a streamlined Life Cycle Assessment including the use of the above coffee machines, production, transportation, and disposal of all packaging materials used, and disposal of spent coffee grounds was carried out in compliance with the Publicly Available Specification (PAS) 2050 standard method. The production of one 40-mL coffee cup with the induction Moka pot gave rise to as low as 8 g CO2e, these emissions being about 18% or 56% lower than those resulting from the use of a coffee capsule (10 g CO2e) or pod (18.5 g CO2e) coffee machine. These estimates might help the eco-conscious consumer to assess the environmental impact of his/her consumption habits. 1. Introduction About 500 billion cups of coffee are consumed worldwide every year (Much Needed, 2020). Thus, coffee is one of the most popular beverages in the world. In 2019 the Italian consumption of roasted and ground coffee amounted to around 304,000 metric tons (Iascone, 2020). -
