Uneven extraction in coffee brewing

Life Cycle Assessment of coffee consumption: comparison of single-serve coffee and bulk coffee brewing

Occurrence of furan in coffee from Spanish market: Contribution of brewing and roasting.

In this work, we evaluated the occurrence of furan in brews obtained from regular, decaffeinated, and instant coffee and commercial packed capsules. For this purpose, a previously developed automated headspace solid-phase microextraction method coupled to gas chromatography-mass spectrometry (HS-SPME-GC-MS) was used. Initially, the influence of HS-SPME conditions on furan formation was evaluate...

Using Uneven Margins SVM and Perceptron for Information Extraction

The classification problem derived from information extraction (IE) has an imbalanced training set. This is particularly true when learning from smaller datasets which often have a few positive training examples and many negative ones. This paper takes two popular IE algorithms – SVM and Perceptron – and demonstrates how the introduction of an uneven margins parameter can improve the results on...

The role of dissolved cations in coffee extraction.

The flavorsome compounds in coffee beans exist in the form of aprotic charge neutral species, as well as a collection of acids and conjugate salts. The dissolution and extraction of these organic molecules is a process dependent on the dissolved mineral content of the water. It is known that different rates and compositions of coffee extraction are achieved through the control of the water "imp...
