What is the secret of coffee baking? what materials can be used as supercapacitors?
Secret 1: to achieve the highest caramelization-caramelization is an important factor affecting the flavor of coffee, as raw beans absorb a lot of heat when roasting, then there is the first 1st cracking, at this time, the sugar begins to be converted into carbon dioxide, water continues to evaporate, the aroma of coffee will gradually come out and form coffee oil. This pyrolysis reaction can last until the second explosion (2nd cracking), but when the second explosion is completed, the temperature of the bean should be lowered immediately and as soon as possible, so that the highest caramelization can be obtained.
Tip 2: minimum carbonization-some ingredients will also be carbonized during the baking process, forming a bad bitter substance, so when you finish the second explosion, stop heating and minimize carbonization at the same time.
Tip 3: pay attention to the change in sound-coffee beans make two bursts during baking, and the first burst is low, indicating that the starch begins to turn into caramel and the water evaporates with carbon dioxide. The second burst sound is more violent and sharp, this is the sound of coffee bean cell fiber fracture, at this time should immediately stop heating, and as soon as possible with cold air to lower the temperature of the bean. The time of the first explosion and the second explosion can be very different, so baking different beans, it is necessary to find out the most suitable baking conditions for this bean.
Tip 4: pay attention to the changes in color and taste-the color of coffee beans will change from green to light brown as it continues to heat up, and then a small amount of oil will show a bright dark brown. At this point, you can no longer bake, otherwise the coffee oil on the surface of the beans will dry and give off a lot of smoke and scorched smell.
To sum up, coffee roasting is a science. The age, density, hardness and moisture content of raw beans will affect the quality of roasted coffee. Even the relative humidity and temperature on the day of roasting can not be ignored.
For coffee beans that have just been roasted, it is best to leave them for 2-5 days. It will be easier to drink after a large amount of carbon dioxide is discharged. Hong Kong Coffee Club uses aluminum foil bags with one-way breathable valves to preserve coffee beans, which can prevent the entry of air and cause oxidation. Carbon dioxide can also be discharged to ensure that the coffee beans are kept in the best condition of freshness.
