The chemical composition of coffee what are the ingredients in coffee beans?
Caffeine: caffeine is the most eye-catching of all the ingredients in coffee. It belongs to a kind of phytoxanthin (animal muscle component). It has the same properties as theobromine contained in cocoa, green tea contains the same theophylline, and the percentage of reduction after baking is very small. Caffeine has a very wide range of effects. will affect the human brain, heart, blood vessels, gastrointestinal, muscle and kidney and other parts, the right amount of coffee

The basic chemical reaction of coffee knowledge during coffee roasting.
Many 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 process includes hydroxylamine.

Coffee training topic Organic Coffee beans
Only a small part of the world's coffee is truly organic certified coffee, because the certification process takes a long time, about three years. And such a deal would reduce coffee production by as much as 50%. So when coffee growers decide to do organic certification, it means that a time-consuming and costly investment begins. Many people think that when coffee is growing, only

What are organic coffee beans?
In many parts of the world, growers use pesticides to control the growth of coffee pests, and moist and foggy coffee at high altitudes are more vulnerable to fungi, so growers often use pesticides to treat them. Many people believe that coffee can be called organic coffee as long as synthetic pesticides, herbicides and chemical fertilizers are not used during coffee growth. in fact, it is only in third parties (except coffee makers and producers).

Basic chemical reactions that occur during coffee roasting
Many thermal and chemical reactions take place during baking: decarbonation, dehydration of quinic acid, fragmentation, isomerization, polymerization, and complex sugar reactions (caramelization). The main thermally reactive components are monosaccharides and sucrose, chlorogenic acid, displaced amino acids, and trigonelline amide. Both aravinone and calactose in polysaccharides are transferred, and basic sulfurization contains hydroxyamino acids.

Knowledge of product quality and food quality and safety
Product quality is the life of an enterprise, and market competition depends on product quality and performance. If an enterprise wants to be competitive in the market and have better economic benefits, it must make great efforts on product quality and take the road of winning by quality. Then, when it comes to the production of specific food and other products, we must effectively ensure the quality and safety of products. The country is people-oriented, and food is the most important thing for the people.

Chemical composition of milk in fine coffee
Milk is made up of protein, fat and sugar. Protein is the medium of foaming, and when the air is pumped into the milk, the protein forms a thin film around the air, wrapping the air to form bubbles. Fat inhibits and destroys the foaming process, although whole milk produces softer foam than skim milk and unfortified milk

Chemical reaction of Fine Coffee in roasting
Coffee has a rich, wide range of flavors. Coffee produced in different regions, different elevations, different climates and different producing areas has its own unique characteristics. Raw beans are fragrant and have no usual coffee taste at all; the taste of coffee comes from proper roasting. Show fruity (light roasting) or caramel sweetness (deep roasting). The lighter the baking, the more sour it tastes. Baking.
