First, the role of carbon dioxide in carbonated drinks (sodas)
Carbonated beverage (soda) products refer to beverages filled with carbon dioxide gas under certain conditions. Carbon dioxide is an important component in carbonated drinks (sodas) and is a characteristic of carbonated drinks (sodas). The role of carbon dioxide in carbonated beverages (sodas) includes the following:
1. Bring out the heat in the human body and give people a cool feeling. When people drink carbonated beverages, carbon dioxide in the beverage is decomposed into carbon dioxide and water due to heat and pressure drop. When carbon dioxide escapes from the body, it will take away heat and make people feel cool. The role of summer heat.
2, can produce special flavor. Carbon dioxide can be combined with other ingredients in the beverage to produce a special flavor. The carbon dioxide escapes from the beverage to bring out the flavor and enhance the flavor characteristics.
3. Inhibit the growth and reproduction of microorganisms in beverages and extend the shelf life. Carbon dioxide in beverages changes the environmental conditions for normal growth and reproduction of microorganisms, resulting in an anoxic environment, which inhibits the growth of microorganisms. It is generally believed that an air content of 3.5 to 4 times can completely inhibit the growth of microorganisms and cause them to die.
Carbon dioxide gas capacity is an important quality characteristic index of carbonated beverages. GB / T10792-2008 carbonated beverages (sodas) specify the carbon dioxide gas capacity test method, as shown in the figure below.
The summary test steps are: pierce the bottle cap → open the vent valve to exhaust → close the vent valve → shake vigorously back and forth for 40 seconds → record the number of megapascals (measure the liquid temperature) after the pressure stabilizes → the result of the carbon dioxide gas volume test. The testing process is relatively complicated, manual operation is tedious, and the workload is heavy. Manual medicine bottles are dangerous. Human error may occur in each test link, resulting in inaccurate test data.
Jinan Theo Electromechanical Co., Ltd. develops and produces a pressure reducer method for carbon dioxide gas volume tester CLRT-01, which is professionally applicable to the test of the volume multiple of carbon dioxide gas volume of carbonated beverages (sodas). (Soda) pressure reducer method (conventional inspection method). The entire test process is completed automatically to improve test efficiency and avoid the impact of manual operations on results.
During the test, only the beverage bottle to be tested needs to be fixed on the sample holder, the instrument automatically pierces the container, vents it, shakes it back and forth continuously for 40 seconds, and then measures the pressure and temperature to obtain the experimental results.
