Aroma is the life of coffee quality, and it can best represent the coffee production process and baking technology, as well as the climate, elevation, variety, refined treatment, harvest, storage, and the appropriateness of baking technology in the consuming country. The results of gas chromatographic analysis showed that the aroma of coffee was composed of acid, alcohol, acetaldehyde, ketone, ester, sulfur compound, phenol, nitrogen compound and nearly hundreds of volatile components. Generally speaking, fat, protein and sugars are important sources of aroma, while lipids blend with the sour and bitter of coffee to form a smooth taste. Therefore, the disappearance of fragrance means that the quality is getting worse, and the relationship between aroma and quality is very close.

The "color and smell" of coffee makes people indulge in it. After reading the above, do you have a thorough understanding of the ingredients of coffee? with the comprehensive effect of these ingredients, coffee can show such mellow aroma, silky taste and good color.

The fat in coffee plays a very important role in flavor. It is found that there are many kinds of fat in coffee, the most important of which are acidic fat and volatile fat. Acidic fat means that the acid in fat varies with the type of coffee, and volatile fat is the main source of coffee aroma. Once the fat in roasted coffee beans comes into contact with the air, it will change chemically and the taste will become worse.

Caffeine is the most eye-catching of all the ingredients of coffee. It belongs to plant xanthamins (animal muscle ingredients) and has the same properties as theobromine in cocoa and theophylline in green tea with a very small percentage reduction after baking.

Caffeine is a mild stimulant that contains less caffeine in our daily drinks such as tea, cocoa and chocolate. Caffeine is also found in carbohydrate drinks such as cola and some anesthetics. It can keep people clear-headed and sensitive. The refreshing effect of coffee is very popular.
