Browning of fruit
Browning Of Fruit. Enzymatic browning because of polyphenol oxidases ppos contributes to the color quality of fruit and vegetable fv products. Polyphenol oxidase ppo and peroxidase pod are the main enzymes responsible for browning. Citric acid and malic acid occur naturally in fruits and so can be added safely to processed fruit without significantly affecting flavour. Enzymatic browning takes place when the enzyme polyphenol oxidase or other enzymes catalyze the oxidation of phenols in the fruit to form compounds called quinones.
Browning In Vegetables And Fruits From brainkart.com
Enzymatic browning is the second largest cause of quality loss in fruits and vegetables. Physical and chemical methods have been developed to inhibit the activity of ppos and several synthetic chemical compounds are commonly being used as ppo inhibitors in fv. Enzymatic browning because of polyphenol oxidases ppos contributes to the color quality of fruit and vegetable fv products. Examples of non beneficial enzymatic browning. Hydrochloric acid will reduce browning but cannot be safely added to food. This reaction is considered undesirable for most fruit and vegetable fv products and seafood such as shrimp.

Enzymatic browning because of polyphenol oxidases ppos contributes to the color quality of fruit and vegetable fv products. A non desirable enzymatic browning reaction is involved in the formation of brown spots on the peel of bananas. Adding acids reduces browning. Browning is a process of gradual change in the color of food products to brown or dark brown over time which can a ect the food quality in either a positive or negative manner 1. The quinones can then polymerize to form melanins which cause the brown pigments. Enzymatic browning is one of the largest causes of quality loss in fruits and vegetables even though it does not make the food harmful to eat.
