Foods and drinks display a broad range of pH values, which relate to the sample’s acidity or alkalinity. Some foods such as meat, dairy products, alcohol, lemon juice, carbonated water, and vinegar fall towards the acidic end of the pH spectrum, whereas common vegetables and fruits fall towards the alkaline end, as shown in the following table. In book: Chemistry and Technology of Soft Drinks and Fruit Juices, Second Edition (pp.279 - 299)
How are soft drinks carbonated and what is the pH of soft drinks? Carbonation is a process wherein pressurized CO 2 is passed through water, producing carbonic acid along with dissolved CO 2 gas. Most carbonated drinks, which are approximately 94% water, have pH around 2.5 to 3.5, and hence are highly acidic.2. Soft drinks can cause weight gain as they interfere with the body’s natural ability to suppress hunger feeling. 3. Soft drinks have ability to dissolve the calcium so they are also harmful for our bones. 4. Soft drinks contain “phosphoric acid” which has a pH of 2.8. So they can dissolve a nail in about 4 days. 5. test no: 1 moisture content in fruit jui ces and soft drinks 1.1.0 Title Moisture content in Fruit Juices and Soft Drinks 1.1.1 Objective To estimate the moisture content in Fruit Juice s and Soft .
Phosphoric acid is one of several weak acids that exist in carbonated beverages. It is a component of all cola soft drinks. Phosphoric acid has a much higher concentration than other acids in a container of soft drink, so its concentration can be determined by a simple acid-base titration. In this experiment, you will titrate a sample of a cola soft drink with sodium hydroxide .5 and 7 respectively using Mann- Whitney test. . Grobler SR, Jenkins GN, Kotze D. Effects of the .In the case of carbonated soft drinks, the flavor concentrates, water and other ingredients are rarely the source of yeasts and lactic acid bacteria (Compendium of Methods for the Microbiological Examination of Foods, 2001, 2015).
