The impact of environmental changes on coffee what affects the quality of coffee? The relationship between coffee and environment

1. Temperature change: the higher the external temperature, the finer the coffee beans will be ground; otherwise, the coffee beans will be ground coarsely. Generally speaking, the environment for coffee production is 18 to 23 degrees. two。 Changes in humidity: the greater the humidity, the thicker the coffee beans are ground. Compared with temperature and humidity, coffee production is mainly affected by ambient temperature. 3. Water quality requirements: generally speaking 70ppm (minerals in water)

The internal changes and characteristics of coffee roasting are mainly to make coffee produce aromatic coffee oil. The amount of heat baked will cause a series of chemical reactions in coffee beans. First, the starch will turn into sugar and acidic substances, and then the basic structure of the coffee bean will change, and the protein will be converted into enzymes, forming a layer of oil in the skin of the coffee bean.

Coffee tasting method Taste belongs to a complex feeling

Taste belongs to a complex feeling. When learning to taste, we must first understand the factors of taste composition, so that we can disassemble and analyze each factor when tasting, and then we can detect more delicate taste, that is, detailed changes.

Roasting technology of boutique coffee beans benefits of wood roasting coffee

All coffee roasting machines work on the same principle: heat raw coffee beans, produce physical and chemical changes and turn them into roasted beans. Physical change means that the color of raw coffee beans changes from green to brown, and the shape changes accordingly. Chemical changes are much more complex, which is the process of production, balance and transformation of substances with fragrance, acidity and other odor components.

Coffee beans wither, too?

Deterioration refers to the change in which the properties of polymers are reduced and cannot be recovered. Due to the action of heat, light, ultraviolet light, oxygen, ozone and various chemicals, polymer materials will change their physical or chemical properties, such as discoloration, cracking, intensity reduction and so on. These external conditions can cause the breakage or cross-linking of the polymer main chain, resulting in structural changes and reduced properties. Baked coffee
