Coffee and Its Effect on Digestion
Expert report Coffee and its effect on digestion By Dr. Carlo La Vecchia, Professor of Medical Statistics and Epidemiology, Dept. of Clinical Sciences and Community Health, Università degli Studi di Milano, Italy. Contents 1 Overview 2 2 Coffee, a diet staple for millions 3 3 What effect can coffee have on the stomach? 4 4 Can coffee trigger heartburn or GORD? 5 5 Is coffee associated with the development of gastric or duodenal ulcers? 6 6 Can coffee help gallbladder or pancreatic function? 7 7 Does coffee consumption have an impact on the lower digestive tract? 8 8 Coffee and gut microbiota — an emerging area of research 9 9 About ISIC 10 10 References 11 www.coffeeandhealth.org May 2020 1 Expert report Coffee and its effect on digestion Overview There have been a number of studies published on coffee and its effect on different areas of digestion; some reporting favourable effects, while other studies report fewer positive effects. This report provides an overview of this body of research, highlighting a number of interesting findings that have emerged to date. Digestion is the breakdown of food and drink, which occurs through the synchronised function of several organs. It is coordinated by the nervous system and a number of different hormones, and can be impacted by a number of external factors. Coffee has been suggested as a trigger for some common digestive complaints from stomach ache and heartburn, through to bowel problems. Research suggests that coffee consumption can stimulate gastric, bile and pancreatic secretions, all of which play important roles in the overall process of digestion1–6. -
Phenolic Compounds in Coffee1
M I N I R E V I E W Phenolic compounds in coffee1 Adriana Farah and Carmen Marino Donangelo* Laboratório de Bioquímica Nutricional e de Alimentos. Departamento de Bioquímica, Instituto de Química, Universidade Federal do Rio de Janeiro, Cidade Universitária, CT, Bloco A, Sala 528-A. Ilha do Fundão, Rio de Janeiro, RJ, 21949-900, Brazil. *Corresponding author: [email protected] Phenolic compounds are secondary metabolites generally involved in plant adaptation to environmental stress conditions. Chlorogenic acids (CGA) and related compounds are the main components of the phenolic fraction of green coffee beans, reaching levels up to 14 % (dry matter basis). These compounds have a number of beneficial health properties related to their potent antioxidant activity as well as hepatoprotective, hypoglycemic and antiviral activities. The main groups of CGA found in green coffee beans include caffeoylquinic acids, dicaffeoylquinic acids, feruloylquinic acids, p-coumaroylquinic acids and mixed diesters of caffeic and ferulic acids with quinic acid, each group with at least three isomers. During coffee processing, CGA may be isomerized, hydrolyzed or degraded into low molecular weight compounds. The high temperatures of roasting also produce transformation of part of CGA into quinolactones and, along with other compounds, melanoidins. This review focuses on the chemical characteristics, biosynthesis, and distribution of CGA and related compounds in coffee. The influence of genetic, physiological and environmental factors as well as processing on the chemical composition of coffee beans is discussed. The impact of CGA composition of green coffee on cup quality is also approached. Despite the existence of substantial published information on the total levels of CGA in coffee, more research is needed on the composition of minor phenolic compounds and specific CGA isomers (and related substances) in green and roasted coffee beans, as well as their impact on coffee quality. -

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). -

Identification of Characterizing Aroma Components of Roasted Chicory
Article Cite This: J. Agric. Food Chem. XXXX, XXX, XXX−XXX pubs.acs.org/JAFC Identification of Characterizing Aroma Components of Roasted Chicory “Coffee” Brews Tiandan Wu and Keith R. Cadwallader* Department of Food Science and Human Nutrition, University of Illinois at Urbana−Champaign, 1302 West Pennsylvania Avenue, Urbana, Illinois 61801, United States *S Supporting Information ABSTRACT: The roasted and ground root of the chicory plant (Cichorium intybus), often referred to as chicory coffee, has served as a coffee surrogate for well over 2 centuries and is still in common use today. Volatile components of roasted chicory brews were identified by direct solvent extraction and solvent-assisted flavor evaporation (SAFE) combined with gas chromatography−olfactometry (GC−O), aroma extract dilution analysis (AEDA), and gas chromatography−mass spectrometry (GC−MS). A total of 46 compounds were quantitated by stable isotope dilution analysis (SIDA) and internal standard methods, and odor-activity values (OAVs) were calculated. On the basis of the combined results of AEDA and OAVs, rotundone was considered to be the most potent odorant in roasted chicory. On the basis of their high OAVs, additional predominant odorants included 3-hydroxy-4,5-dimethyl-2(5H)-furanone (sotolon), 2-methylpropanal, 3-methylbutanal, 2,3- dihydro-5-hydroxy-6-methyl-4H-pyran-4-one (dihydromaltol), 1-octen-3-one, 2-ethyl-3,5-dimethylpyrazine, 4-hydroxy-2,5- dimethyl-3(2H)-furanone (HDMF), and 3-hydroxy-2-methyl-4-pyrone (maltol). Rotundone, with its distinctive aromatic woody, peppery, and “chicory-like” note was also detected in five different commercial ground roasted chicory products. -

Understanding the Evolving Roles of Outbound Education Tourism in China: Past, Present, and Future
Athens Journal of Tourism - Volume 7, Issue 2, June 2020 – Pages 100-116 Understanding the Evolving Roles of Outbound Education Tourism in China: Past, Present, and Future By Sandy C. Chen* This paper discusses the evolving roles of outbound education tourism in China. To provide a thorough understanding, it first surveyed the origins and philosophy of travel as an educational device as well as education travelers’ motivations in Chinese history from the first pioneers in the Confucian era to the late 20th century. Then, it described key events and factors that have stimulated the development of the outbound education tourism in modern China and its explosive growth in the 21st century. Through in-depth personal interviews, the study developed a set of measures that reflected present Chinese students’ expectations of traveling abroad to study. A follow-up large-scale survey among Chinese students studying in the United States revealed two dimensions underlining these expectations: Intellectual Growth and Lifestyle. The findings of the study have significant implications for key stakeholders of higher education such as administrators, marketers, faculty, staff, and governmental policy-making agencies. Keywords: Education tourism, Outbound tourism, Chinese students, Travel motivation, Expectations. Introduction Traveling abroad to study, which falls under the definition of education tourism by Ritchie et al. (2003), has become a new sensation in China’s outbound tourism market. Indeed, since the start of the 21st century, top colleges and universities around the world have found themselves welcoming more and more Chinese students, who are quickly becoming the largest group of international students across campuses. Most of these students are self-financing and pay full tuition and fees, thus every year contributing billions of dollars to destination countries such as the United States, the United Kingdom, Canada, Australia, Germany, France, and Singapore.
