Coffee extraction: A review of parameters and their influence on the physicochemical characteristics and flavour of coffee brews
Publication date: Available online 12 December 2019Source: Trends in Food Science &TechnologyAuthor(s): Nancy Córdoba, Mario Fernandez-Alduenda, Fabian L. Moreno, Yolanda. RuizAbstractBackgroundThe physicochemical characteristics and flavour of coffee are related to the volatile and non-volatile compounds produced during roasting, which reach the coffee cup upon brewing.Scope and approachThis review focuses on interpreting the contribution that various parameters have during the coffee extraction process (coffee brewing). Coffee brewing methods and their extraction parameters were analysed in terms of phenomenological explanations and their effect on the physicochemical and flavour characteristics of brewed coffee.Key findings and conclusionsMany brewing methods have been developed to achieve a myriad of coffee flavour characteristics. Although several well-known brewing techniques have been adopted in the coffee industry, little associated relevant scientific data is available. Overall, these methods vary by extraction pressure, coffee/water ratio, water quality, contact time, particle size distribution, and temperature. An overview shows that all these factors modify the extraction of bioactive and volatile compounds that affect the flavour profile of the beverage. However, more in-depth explanation of the mass and energy transport phenomena would be useful to improve the understanding of the relationship between extraction variables and coffee flavour. Thus, phe...

CONCLUSION: Use of VR facility tours as an alternative to in-person tours of affiliate training facilities during a residency interview day is a viable and innovative option that can save time and money and favorably impact the applicant's impression of the program. More research is necessary to assess whether VR tours can replace in-person tours at the main teaching site, however, while social distancing measures are in place, VR tours may become necessary for programs moving forward.

Authors: Roberts V, Malone K, Moore P, Russell-Webster T, Caulfield R Abstract Our personal views about the challenges of continuing to deliver peer teaching during a pandemic. We are a group of 4th year medical students who are part of a student society which has delivered structured, highly formulaic peer-led teaching sessions for the past three years. During the COVID-19 pandemic, the reduced access to our normal clinical teaching highlighted the importance of peer-led teaching sessions. We wanted to continue with our peer-taught sessions but knew we would have to devise a new format to make our teaching accessi...
