Beverage tubing is one of the most important process when you are making beverages, either at home or on a big scale. Usually this process takes place when you want to carbonate your beverage. This process is very important because if your beverage is not carbonated it will not have the taste which other sodas and beverages have. The beverage will be flat or tasteless. People enjoy fizzy drinks which are carbonated and which gives them burps. This is done by the help of carbonating your beverages.
Oxygen is element which keeps the humans, animals and plants alive because this is the element that we need to breathe to keep us alive. Oxygen is the enemy of food and beverage products, if you keep a beverage open for a long time you will find the beverage flat, this is because the oxygen has been accumulated with your beverage because flavor is one such property that changes when oxygen hits it because oxygen is highly reactive and chemically bonds with compounds found in food and changing their properties.
Usually empty bottles do not have Co2 in it, it is filled with oxygen, and beverage tubing is the process which helps carbonate your drink. To check that your beverage contains Co2 shake the bottle before opening the seal, the liquid will look mostly like bubbles and when you open the seal of the bottle the liquid will splash out of the bottle.
When making homemade beverages, try connecting two bottle caps with a piece of clear tubing and screwing them on to the bottles, one bottle will contain the beverage and the other bottle containing vinegar and baking soda, the Co2 from the bottle containing vinegar will pass through the tube and goes in the beverage containing bottle. This process carbonates your beverage and this device sells cheap for round about $7. This process makes it extremely impossible for air to go through.
Without beverage tubing process your beverage will be tasteless as beverages should contain some "fiziness". Usually most beverages contain carbonated water if you check through the ingredients. You should know that carbonating apple, grape, pomegranate, watermelon and cantaloupe juices.
Big companies use other techniques and machines to carbonate their drinks. Some use to process of dry ice, dropping 3 to 4 grams of pellets into a 2 liter bottle that is one third empty before capping the bottles, use 8 to 10 grams if it is half empty. If there is not enough liquid in the bottle to fully carbonize it then you should leave it as it will not help then. You must remove all the oxygen in the bottle and replace it will Co2 that was lost before. Much simpler method is that you buy yourself a home carbonation unit; you will find it available on many websites for sale which will range from $100 to maximum $250. There are many home beverage maker manufacturers who use this equipment.
