Application of PAL-coffee Concentration Meter in Coffee Extraction Rate and Concentration Mixing in Chain Coffee Shop

Coffee should be based on the taste, the extraction rate data can help to correct the method when the taste of the coffee is wrong, the data has a reference, but it is not the absolute criterion of taste.
TDS = Total Dissolved Solids is a measurement tool used to measure the total solids content dissolved in water; concentration, extraction rate is a reference for measuring the quality of a cup of coffee. As long as the coffee concentration is between 1.15 and 1.35 and the extraction rate is between 18% and 22%, it can be said that the coffee is basically qualified. The so-called extraction rate is how much coffee powder is placed in the water and how much is dissolved in the water. According to SCAA theory, up to 30% of the material will be dissolved in water. Extraction rate formula = mass of extracted material / total mass of matter *100.
Recently, the General Administration of Quality Supervision, Inspection and Quarantine conducted a national supervision and inspection on the quality of tea beverage products and issued relevant quality standards. In some products, important physical and chemical indicators such as caffeine and tea polyphenols were unqualified. Tea polyphenols and caffeine indicators are characteristic indicators in tea beverages and are mandatory provisions in tea beverage standards. The content of tea polyphenols and caffeine in different types of tea beverages must reach the corresponding level, otherwise it cannot be called Drink. The main reason for the unqualified tea polyphenols and caffeine indicators in tea beverages is that the content of tea polyphenols and caffeine in raw materials is insufficient, the raw material testing is not strict, the production process parameters and batching measurement control are not strict, and the quality inspection of finished products is checked. Not enough or lack of necessary testing methods and other problems.
