Coffee mate case study

Mercola Have you ever heard the urban legend that non-dairy coffee creamer is flammable? I even know of some people who have used non-dairy creamer to start their campfires! Which, of course, begs the question… what is this stuff made of, and do you really want to add it to your morning coffee? If you drink coffee, the best way to drink it is black without sugar or cream and preferably organic.

November 15,Society for Industrial and Applied Mathematics a Espresso coffee is made by forcing hot water under high pressure througha compacted bed of finely ground coffee. In either method water flows through the bed, leaching soluble coffee components from the grains. Any undissolved solids in the fluid are filtered from the extract as the liquid leaves the filter.

Moroney Composed of over 1, chemical components, coffee is one of the most widely-consumed drinks in the world.

The seeds coffee beans from the plant of the same name are roasted and ground, allowing a flow of hot water to extract their soluble content.

Undissolved solids are filtered from the dissolved particles, and the resulting liquid becomes the concoction that much of the population drinks every day. Brewers have developed numerous techniques to prepare the popular beverage. All techniques are based on leaching via a solid-liquid extraction, and each method aims to produce the best quality coffee possible - a subjective feat that, despite evaluations from professional coffee tasters, is often a matter of personal preference.

Because so many chemical compounds comprise a single batch of coffee, determining precise correlations between the solubles' physical parameters and the beverage's quality is difficult. However, understanding the mathematics of extraction can help identify the influence of various parameters on the final product.

O'Brien, Freek Suijver, and Johan Marra present and analyze a new multiscale model of coffee extraction from a coffee bed. While past studies have investigated the mathematics of coffee extraction, researchers have previously paid little attention to the drip filter brewing system.

Gravity pulls the water through the filter, extracting coffee solubles from the grains during the flow. Our initial focus on the flow-through cylindrical brewing chamber allowed us to consider the model in one spatial coordinate and ensure that the model assumption of a static bed was valid.

Moroney The authors' earlier paper presents the derivation of this general model, which considers bed dimensions, flow rates, grind size distribution, and pressure drop. They assume isothermal conditions constant temperaturebecause optimal brewing circumstances require a narrow temperature range of degrees Celsius.

They also assume that coffee bed properties remain homogeneous in any cross section and that water saturates all pores in the coffee bed, eliminating the need to model unsaturated flow. A set of conservation equations on the bed scale monitor the transport of coffee and liquid throughout the coffee bed.

Now the authors take that model one step further. For example, real coffee contains a large number of dissolved substances; we simplify our model by considering the case of a single such substance.In May, , a Working Group of 23 scientists from ten countries met at the International Agency for Research on Cancer (IARC) in Lyon, France, to evaluate the carcinogenicity of drinking coffee, mate, and very hot beverages.

The genus Coffea is native to tropical Africa (specifically having its origin in Ethiopia and Sudan) and Madagascar, the Comoros, Mauritius, and Réunion in the Indian Ocean. Coffee plants are now cultivated in over 70 countries, primarily in the equatorial regions of the Americas.
