Preservation of reddish color of lychee pericarp

摘要

The reddish pericarp color of whole fresh lychee fruit is preserved by applying a composition of a food acid, an edible reducing agent, and a carbohydrate thickener to the pericarp surfaces, and thereafter storing the coated fruit at a low temperature. After initial coating, the lychee fruit is preferably frozen and then recoated before storage in frozen condition.
