2016-01-23 Coffee roasting process medium hair raw basic chemical reaction degree produced madeMany thermal and chemical reactions take place during baking: decarbonation, dehydration of quinic acid, subdivision, isomerization, polymerization, and complex sugar reactions (caramelization). The main components of the thermal reaction are monosaccharides and sucrose, chlorogenic acid, free amino acids, and fenugreek amide. Both aravinose and calactose in the polysaccharides are transferred, and the basic vulcanization contains hydroxylated amino acid.

2014-10-09 Coffee knowledge coffee technology coffee roasting baking chemical reactionYega Xuefei's grading system is not based on the number of eyes, but on the proportion of defective beans in the total number of raw beans. Commonly seen are wash G2 and sun G3 Yega Chuefei, G1 is the highest grade, Yega Xuefei, which has the lowest defect rate and the best quality, can be rated as Grade 1 only after hand selection. A system is scattered in the northern part of the Great Rift Valley of East Africa.

2016-08-15 Soft fragrant granular full Rwanda coffee manor producing area flavor tasteFirst of all, we should know clearly that the factors that ultimately determine the flavor of coffee come from the environment of its producing area, the way of treatment and the quality of raw beans. I believe that without better raw beans, no matter how good the roaster will not bake amazing coffee. Of course, when good coffee beans are in the hands of baristas, baristas should fully understand their characteristics and then add icing on the cake.
2016-04-18 Coffee common sense grading system summary countries methods selection determination originThe evaluation criteria of Egyptian beans were developed with the assistance of the American Fine Coffee Association (SCAA). (why can't Egypt, as the home country of coffee, formulate it independently? Yeah! Think about it)-Egypt fully implemented a central auction system in 2008 (used to be purchased by exporters)-briefly talk about some pre-auction processes. 1) Farmers pick fresh coffee fruit; 2) Farmers take fresh coffee

Most of the beans are small and pointed long beans, the so-called longberry, and often mixed with small oval-shaped short beans, the so-called shortberry, looks uneven in size and uneven in appearance
