Polyphenol oxidase is an enzyme found throughout the plant and animal kingdoms, [31] including most fruits and vegetables. [32] PPO has importance to the food industry because it catalyzes enzymatic browning when tissue is damaged from bruising, compression or indentations, making the produce less marketable and causing economic loss.
They were developed through a process of genetic engineering by Okanagan Specialty Fruits Inc. [4] [5] Specifically, gene silencing reduces the expression of polyphenol oxidase (PPO), thus delaying the onset of browning. [6] It is the first genetically engineered apple to be approved for commercial sale. [7]
An example of such accomplishments in food engineering is in the production of Arctic apples. These apples, engineered by Okanagan Specialty Fruits Inc, are a result of applying gene splicing, a laboratory technique that has allowed for the reduction in polyphenol oxidase. Another type of issue that is closely studied is the browning of seafood ...
Apple skins and seeds contain polyphenols. [94] These are oxidised by the enzyme polyphenol oxidase, which causes browning in sliced or bruised apples, by catalyzing the oxidation of phenolic compounds to o-quinones, a browning factor. [95] Browning reduces apple taste, color, and food value.
Research has linked consumption of 70% dark chocolate with improved cognitive performance, so aim for chocolate that contains at least 70% cocoa or higher to get optimal polyphenol and anti ...
Apples. This is one of Eisenberg’s favorite fruits. Apples are a major source of fiber, and contain vitamin C and polyphenols, a type of phytochemical with a cholesterol-lowering effect, the ...
These potential benefits may have something to do with the antioxidants found in coffee, like chlorogenic acid and polyphenols, which help reduce inflammation and support blood vessel function ...
opal® is the brand name for apple cultivar 'UEB 32642'. The variety originates from a natural crossing of 'Golden Delicious' with 'Topaz'. [1]Developed by the Institute of Experimental Botany in Prague, [2] it is grown by FirstFruits Farms LLC in Washington and marketed by FirstFruits Marketing.
