Aroma is the life of coffee quality-the best expression of coffee production process and roasting technology
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.
