Little knowledge of coffee extraction rate and concentration in chain coffee and beverage stores

Coffee should be based on the taste, the extraction rate data can help to correct when there is something wrong with the taste of coffee, the data can be used as a reference, but it is not the absolute criterion of taste.

TDS=TotalDissolved Solids is a measuring tool used to measure the total content of dissolved solids in water; concentration and extraction rate are the reference indicators to measure the quality of a cup of coffee. As long as the coffee concentration is 1.15-1.35 and the extraction rate is 18%-22%, it can show that this cup of coffee is basically qualified. The so-called extraction rate is how much coffee powder will be dissolved in water when it is placed in water. According to SCAA theory, up to 30% of the material will be dissolved in water. Extraction rate formula = the mass of the extracted material / the total mass of the substance * 100.

Recently, AQSIQ has conducted a national supervision and spot check on the quality of tea beverage products and laid down relevant quality standards. Some important physical and chemical indexes such as caffeine and tea polyphenols are not up to standard. Tea polyphenols and caffeine are characteristic indexes in tea beverages, and they are mandatory provisions in tea beverage standards. The contents of tea polyphenols and caffeine in different types of tea drinks must reach the corresponding level, otherwise they cannot be called beverages. The main reasons for the unqualified indexes of tea polyphenols and caffeine in tea beverages are the insufficient content of tea polyphenols and caffeine in raw materials and the lack of strict inspection and control of raw materials. problems such as inadequate metering control of production process parameters and ingredients, inadequate quality inspection of finished products or lack of necessary testing means, etc.

ATAAGO (Alto) PAL-coffee (TDS scale) Coffee concentration Meter is light and easy to carry, humanized engineering design, can be measured with one hand at the press of a button, and clear water returns to zero. It can quickly keep the sample consistent with the prism temperature, easy to sample and not easy to leak and pollute the instrument, easy to maintain, meet the IP65 standard, and can be washed directly with running water. PAL-coffee (Brix scale) Coffee concentration Meter, if the coffee concentration is higher, the new product model PAL-coffee (Brix value) can be used to measure the range of 0.00525.00%. Manage and control the blending concentration of coffee to ensure the quality of the product.
