The role of beer carbon dioxide content analyzer in the development experiment of beer brewing
Date: 2025-08-13Read: 2
Carbon dioxide (CO ₂) is an important gas produced during the beer brewing process. It is not only a byproduct naturally produced during beer fermentation, but also has a significant impact on the foaming effect, taste, and oral sensation of beer. Appropriate carbon dioxide content can endow beer with rich foam, enhance the refreshing feeling and rich taste when drinking.
Low carbon dioxide content may cause beer to lose foam and taste bland; If the carbon dioxide content is too high, it may lead to a pungent or unpleasant sour taste in beer. Therefore, in the production and packaging process of beer, it is necessary to accurately measure the content of carbon dioxide and adjust the appropriate amount of carbon dioxide according to different types of beer (such as lager, ale, beer aroma, etc.).
Beer carbon dioxide content analyzerWorking principle:
(1) Pressure method (dissolved gas method)
The pressure method calculates the gas content by sealing a beer sample in a pressure vessel and measuring the dissolution pressure of carbon dioxide gas. According to Henry's Law, the amount of gas dissolved is proportional to its partial pressure in a liquid. By controlling the temperature and reading pressure changes, the instrument can estimate the concentration of carbon dioxide dissolved in beer.
(2) Infrared absorption method
The infrared absorption method utilizes the specific absorption wavelength characteristics of carbon dioxide in the infrared spectrum. When the beer sample passes through an infrared light source, carbon dioxide molecules absorb specific wavelengths of light. Measuring the light intensity absorbed by carbon dioxide molecules can accurately calculate their concentration in the sample. This method usually has high accuracy and can respond quickly.
(3) Chemical titration method
The chemical titration method converts carbon dioxide in beer into titratable chemicals, and calculates the carbon dioxide content based on the amount of titrant used. This method is generally suitable for laboratory environments and can obtain high-precision results, but the operation is relatively cumbersome and suitable for precise laboratory testing.
Application of Beer Carbon Dioxide Content Tester:
(1) Beer production
The control of carbon dioxide content is crucial for the quality of the final product in the beer production process. Widely used in various stages of the production process, from monitoring the fermentation stage to quality control during filling, precise measurement of carbon dioxide content is required.
(2) Laboratory research
In the research and development experiments of beer brewing, researchers need to accurately measure the changes in carbon dioxide to study the effects of different brewing processes, fermentation times, and temperatures on the concentration of carbon dioxide in beer. This type of measuring instrument can provide reliable data support for experiments and optimize brewing processes.
(3) Quality control
The stability of carbon dioxide content is an important criterion for measuring product quality in the production and sales process of beer. It can help manufacturers conduct real-time inspections throughout the entire production cycle to ensure that each bottle of beer meets quality requirements.
(4) Imported beer testing
For imported beer, especially beer produced in different countries and regions, there may be differences in the carbon dioxide content standards. By using a carbon dioxide content analyzer, it is possible to verify whether imported beer meets domestic standards and ensure the interests of consumers.
