Companies who create bottled fruit juices are legally required to make a distinction between a fruit drink and a fruit juice. Bottled products named with blend, drink or beverage usually contain ten percent juice or less. They are generally nothing more than water with sugar added. Items labeled as ciders or juice must be real fruit juice.
Just about all of the juice you find at your local grocery store has been pasteurized. Pasteurization is a process designed to kill harmful pathogens and bacteria. Pasteurization is a very effective sterilization process and allows us to extend the shelf life of many things. Regular pasteurization and flash pasteurization both use high temperature to remove the harmful.
The main drawback to pasteurization is that helpful elements are lost as well. According to General Bacteriology 12th edition, vitamin C is reduced by half during the process. It further states that children who drink only pasteurized milk may lack vitamin C and be at risk. Lori Lopinski makes the claim that fifty percent of the vitamin C is milk is destroyed in her article Milk: It Does a Body Good. Furthermore, additional vitamins like A, D and E are removed as well. The vitamin C loss is more significant since it is water soluble while the others are fat soluble.
Vitamin loss during pasteurization is a source of argument. There are claims that very little nutrients are eliminated in contrast to those presented above. One thing you can do is see if your particular juice is adding vitamin C. One of the ingredients on the label of your juice is likely ascorbic acid. Ascorbic acid is another name for vitamin C. Synthetic nutrients are added to replenish what was eliminated. The company does this so they can make claims that there is a daily supply of vitamin C in an eight ounce serving.
Some juices are not pasteurized. The west coast company Odwalla used to sell unpasteurized juice prior to 1996. In that year, Odwalla caused some E coli related deaths with their juice. All of their products have been pasteurized since this incident. Odwalla was acquired by The Coca-Cola Company in 2001. Companies are required to note on the package if the contents have been pasteurized. This is done to inform the public which juices are deemed safe for consumption.
Exposure to oxygen also destroys vitamin C. The vitamin is an antioxidant. In other words it oxides easily. Oxidation is a term used when substances react with oxygen to form stable compounds. The term anti-oxidant means that the oxygen will bind with it rather than other substances, preventing their oxidation. Free radicals like oxygen are chemicals that harm living tissues. By consuming antioxidants the free radicals are neutralized before they hurt organs or tissues. The oxygen present in the atmosphere will trigger a reaction.
