The basic chemical reaction of coffee technology in the process of coffee roasting

The basic chemical reaction of coffee technology in the process of 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.

Why does coffee smell so good? Caramelization and Mena reaction during coffee roasting

The charming aroma of coffee is also the main reason why Napoleon, me and many coffee fans miss coffee all the time. But why on earth does the coffee smell so good? The most important thing, of course, is that coffee beans themselves are rich in a variety of raw materials, such as carbohydrates, proteins, lipids, organic acids, etc., and then heated and baked will start a series of complex reactions and create an attractive aroma.

Introduction to the kinds of Coffee Sugar

White granulated sugar, also known as sucrose, is a granular crystal and is the basic raw material for sugar production. According to the size of the crystal, there are three kinds of sugar: coarse sand, medium sand and fine sand, all of which are made from sugar cane or sugar beet. It is characterized by high purity, low moisture and few impurities. The content of domestic granulated sugar is more than 99.45% and the moisture content is less than 0.12%. According to the standard, it is divided into three types: excellent grade, first grade and second grade.

Do not drink unbaked coffee roasting degree

Do not drink unbaked coffee roasting degree

The heat of shallow roasting is mild, because the sour aroma of flowers and fruits is most preserved by fermentation, so it is easy to smell the sour aroma of coffee. If the baking continues, that is, from the end of the first explosion to the middle baking before the second explosion, or even the medium and deep baking from the first explosion to the second explosion, most of the sour aroma of the fermentation catalysis has been broken up, instead of the taste spectrum of the sugar browning reaction (Sugar Browning) and Mena reaction.
