In the context of roasted and ground coffee, legumes, cereals, nuts and other vegetables are often used to augment the production volume; however, these adulterants lack the most important coffee compound, caffeine, which has health benefits. In this study, the mid-infrared Fourier transform spectroscopy (FT-MIR) technique coupled with chemometrics was used to identify and quantify adulterants in coffee (Coffea arabica L.). Coffee samples were adulterated with corn, barley, soy, oat, rice and coffee husks, in proportions ranging from 1–30%. A discrimination model was developed using the soft independent modeling of class analogy (SIMCA) framework, and quantitative models were developed using such algorithms as the partial least squares algorithms with one variable (PLS1) and multiple variables (PLS2) and principal component regression (PCR). -

The Economic Value of Coffee (Coffea Arabica) Genetic Resources
The economic value of coffee (Coffea arabica) genetic resources Lars Hein1* and Franz Gatzweiler2 * corresponding author 1 Environmental Systems Analysis Group, Wageningen University, P.O. Box 47, 6700 AA, Wageningen, Phone: +31-316-482994 / Fax: +31-317-484839, Email: [email protected] 2 Centre for Development Research (ZEF), Department of Ecology and Resource Management, Bonn University, Walter-Flex Str. 3, D-53113 Bonn, Phone: +49-228-731795 / Fax:+49-228-731889, Email: [email protected] Abstract Whereas the economic value of genetic diversity is widely recognized there are, to date, relatively few experiences with the actual valuation of genetic resources. This paper presents an analysis of the economic value of Coffea arabica genetic resources contained in Ethiopian highland forests. The valuation is based on an assessment of the potential benefits and costs of the use of C. arabica genetic information in breeding programs for enhanced coffee cultivars. The study considers the breeding for three types of enhanced cultivars: increased pest and disease resistance, low caffeine contents and increased yields. Costs and benefits are compared for a 30 years discounting period, and result in a net present value of coffee genetic resources of 1458 and 420 million US$, at discount rates of 5% respectively 10%. The value estimate is prone to considerable uncertainty, with major sources of uncertainty being the length of breeding programs required to transfer valuable genetic information into new coffee cultivars, and the potential adoption rate of such enhanced cultivars. Nevertheless, the study demonstrates the high economic value of genetic resources, and it underlines the need for urgent action to halt the currently ongoing, rapid deforestation of Ethiopian highland forests. -

An antioxidant is a compound that can be scavenged free radicals. Coffee is one of the natural antioxidants. This research aimed to study the antioxidant activity of medium roasted beans of liberica coffee (Coffea liberica) from three different regions by DPPH and CUPRAC methods. To determine total phenolic content (TPC) and total flavonoid content (TFC), analyze the correlation between TPC and TFC with AAI DPPH and CUPRAC and the correlation between two methods in sample extracts. The sample was extracted by reflux using n-hexane, ethyl acetate, and ethanol. AAI DPPH in the range of 0.397- 18.536, while CUPRAC 0.532-4.674. The highest TPC in ethanol extract of liberica coffee from Aceh (22.585 ± 1.610 g GAE/100 g) and the highest TFC in ethyl acetate extract of liberica coffee from Aceh (4.927 ± 0.355 g QE/100 g). TPC of all samples had a positive and significant correlation with AAI DPPH and CUPRAC. AAI DPPH and CUPRAC value gave a significant and positive correlation. -

However, a combined negative factor, including, among others, climate crisis, the incidence of diseases and pests, and poor land-use planning, have led to a decline in coffee yields, impacting on the family economy. Therefore, this research assesses land suitability for coffee production (Coffea arabica) in Amazonas region, in order to support the development of sustainable agriculture. For this purpose, a hierarchical structure was developed based on six climatological sub-criteria, five edaphological sub-criteria, three physiographical sub-criteria, four socio-economic sub-criteria, and three restrictions (coffee diseases and pests). -

INTRODUCTION Coffee is the second largest export commodity in the world after petro leum products with an estimated annual retail sales value of US $70 billion in 2003 (Lewin et a1. 2004). Over 10 million hectares of coffee were harvested in 2005 (http://faostat.fao.orgl) in more than 50 devel oping countries, and about 125 million people, equivalent to 17 to 20 million families, depend on coffee for their subsistence in Latin Amer ica, Africa, and Asia (Osorio 2002; Lewin et a1. 2004). Coffee is the most important source of foreign currency for over 80 developing countries (Gole et a1. 2002). The genus Coffea (Rubiaceae) comprises about 100 different species (Chevalier 1947; Bridson and Verdcourt 1988; Stoffelen 1998; Anthony and Lashermes 2005; Davis et a1. 2006, 2007), and new taxa are still being discovered (Davis and Rakotonasolo 2001; Davis and Mvungi 2004). Only two species are of economic importance: C. arabica L., called arabica coffee and endemic to Ethiopia, and C. canephora Pierre ex A. Froehner, also known as robusta coffee and endemic to the Congo basin (Wintgens 2004; Illy and Viani 2005). C. arabica accounted for approximately 65% of the total coffee production in 2002-2003 (Lewin et a1. 2004). Dozens of C. arabica cultivars are grown (e.g., 'Typica', 'Bourbon', 'Catuai', 'Caturra', 'Maragogipe', 'Mundo Novo', 'Pacas'), but their genetic base is small due to a narrow gene pool from which they originated and the fact that C. -
Physiology of Flowering in Coffea Arabica L.: Role of Growth Regulators and Water Relations by Ursula K
AN ABSTRACT OF THE THESIS OF Ursula K. Schuch for the degree of Doctor of Philosophy in Horticulture presented on October 4. 1990 . Title: Physiology of Flowering in Coffea arabica L.; Role of Growth Regulators and Water Relations Abstract approved: _„ -r-— —~- - ' - ^~—— ——-7- / Leslie H. Fiichigam^ Coffee trees growing in the Kona district of Hawaii were treated with different concentrations of either BA, GA3, or Promalin, and pruned at the time of flowering. No significant differences in the flowering and fruit ripening pattern were found. High concentrations (100 mg/1) of growth regulators decreased fruit fresh weight. Pruning yielded the lowest number of fruit and flowers, and caused branch dieback. Fruit set was between 46 and 83% for the two years studied. Flower buds from trees growing in the field that were >4 mm, but not developed to the candle stage at the time of GA3 treatment, reached anthesis 20 days earlier than the controls. Their development was independent of rainfall, unlike the controls. Fruit from buds that had been treated at the >4 mm or the candle stage ripened more synchronously and earlier than the control. Buds smaller than 4 mm did not respond to GA3 treatment. A threshold leaf water potential of -2.7 MPa, and flower bud water potential of about -4.0 MPa was necessary to overcome dormancy of flower buds in greenhouse grown trees. GA3 stimulated anthesis in some plants that were stressed to leaf water potentials of -2.1 MPa. Ethylene evolution of flower buds where dormancy had been broken with water stress was low, compared to dormant flower buds. -

The coffee species most commercialized worldwide are Arabica (Coffea arabica) and Robusta (Coffea canephora). Roasted coffee beans are the most used, but coffee leaves are also consumed as infusion in several countries for traditional medicinal purposes. They contain several interesting phenolic antioxidant compounds mainly belonging to chlorogenic acids (CGAs). In the present work, a liquid chromatography-electrochemical detection (LC-EC) method was developed for the determination of three main chlorogenic acid isomers, namely 3-, 4-, and 5-caffeoylquinic acids (CQA), in coffee leaves aqueous extracts. -

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]. -
What Is Cascara? Coffee, Tea, Superfood?
What is Cascara? Coffee, Tea, Superfood? After walking into a coffee shop in Washington D.C. recently, I was quite surprised that they were promoting a new drink for 2017 on the menu called “Cascara”, with a subtitle stating “Warm and nutty caramel tones made from the skin of coffee cherry blossoms”. I asked the barista if this was tea or coffee. She looked perplexed and said to me, “no, it’s a syrup”. Needless to say I was confused, but intrigued. So I thought to myself, a new drink being showcased at this coffee shop which could seem to be a healthier alternative to coffee, yet it’s syrup. This is the brilliance of marketing, which makes you excited about something new being available as a coffee alternative. I proceeded not to order it because I didn’t fully understand what they were offering. Was it tea, coffee, syrup, or all of it mixed together? Either way, if I was to order Cascara, I would want the real super food coffee cherry tea version I heard of, not a syrup mixed into a hot drink. My visit to this coffee shop left me wondering, what is this elusive Cascara being offered, and is it really coffee or tea? After further research, I found that Cascara (translated from Spanish meaning ‘husk’ or ‘peel’) is also known as coffee cherry skins in English. Cascara must not be confused with the herbal plant with a similar first name, Cascara Sagrada (Chittem Bark), which is completely different and has natural laxative properties when consumed. -
