Origin
E 904 is a resin that is a secretion produced by lac insects in India and China. The secreted resin accumulates on the host tree of the lac insects and is harvested from these trees for shellac production. Subsequently, the secretion is ground down and cleaned to food-grade quality. Approximately 300,000 lac insects are needed for one kilogram of shellac. Shellac is an odorless and tasteless substance that is brittle and insoluble in water.
Usage
E 904 is frequently used as a coating material for certain fruit varieties; it is also often combined with shellac and beeswax (E 901). E 904 can be found in the treatment of peaches, apples, pears, pineapples, melons, and citrus fruits. Additionally, E 904 is approved for use in coffee beans, dietary supplements, confectionery, snack foods, and chocolate.
Risks
The food additive E 904 is considered harmless to the human organism. An ADI value (Acceptable Daily Intake) has not been established.
