Abstract:

The occurrence of the limonoid aglycone limonin, responsible for bitterness in citrus juice, remains a major
impediment to the development of citrus juice industry worldwide. Biotransformation of limonin for ameliorating bitterness
has been unequivocally suggested to be the current method of choice. This article mainly focuses on the recent progress
in the structure and classification, natural biotransformation and delayed bitterness of limonoids as well as debittering by
enzymatic methods, immobilized cells and genetic engineering.

Key words: citrus, limonoids, limonin, natural biotransformation, biological debittering
