The five stages of baking: 1. Dry, when the raw bean is heated, the water vapor in the raw bean will evaporate, and when it reaches about 135 degrees, the raw bean begins to lighten from green and gradually whitens. two。 Dehydration, as heating, raw beans from green to light yellow, when the temperature is about 160 degrees, will emit the smell of grass, or the aroma of baked grain, continuous heating, beans will turn light brown. 3. one

The baking degree ranges from the shallowest 100 to the deepest 25, which is expressed by the value that the baking degree is about Agtron50. The determination is based on a special colorimeter called AgtronM-Basic. Baking degree

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.

In the United States, the degree of roasting has long been defined by Cinnamon (shallow roasting), City (shallow roasting), Fully City (deep roasting) and Dark roast (heavy deep roasting, including Italian and French). However, the American preference for coffee flavor has always been strong in the west and light in the east, so on the west coast.

(for example, I-ROAST) is to try baking several times by adjusting the time on the machine, or by controlling the baking degree recommended by the manufacturer. Then adjust the baking degree according to the decreasing time. If you think the baking is too sour and too bright, extend it a little longer next time, on the contrary.

In this process, if there is a deviation in the procedure, the flavor of the coffee will be very different. Take baking, for example, it is divided into several levels. Next, Fulaigao coffee experts will introduce the degree and characteristics of roasting. An expert introduction to Fulaigao Coffee

Judging from the taste and aroma of coffee, delicious coffee is as sour as citrus fruit without strong sour taste. Bitterness is a soft bitterness. There is no bitterness like cigarette or scorch. The shape was discussed before judging from the quality of raw beans.

2015-09-14 Coffee roasting definition taste problem beans common sense again talk about all kinds ofFrom the point of view of the baking degree, the deeper the baking degree, the stronger the bitter taste; the lighter the baking degree, the stronger the sour taste. The choice of baking degree depends on the characteristics of the coffee bean itself. For coffee beans with strong bitter taste and light sour taste, they generally choose a moderate and shallow roasting degree. 1. Light baking (Light) the lightest fried culture, no aroma and concentration, and the beans are not ripe yet.

The above colors are for reference only according to the roasting degree preferred by each country. This is also coffee roasting.
