Introduction      :
Citrus limonoids are responsible for the bitter taste in citrus fruits. The most prevalent limonoids are limonin and nomilin. They are present in the rutaceous plants that include lemon, lime, orange and grapefruits. An important characteristic of this class of compound is a substituted furan moiety.
It has been determined by animal studies that citrus limonoids and derivatives have certain biological activities that may be used as chemopreventive agents for cancer.

Limonin is a limonoid, and a bitter, white, crystalline substance found in citrus and other plants. It is also known as limonoate D-ring-lactone and limonoic acid di-delta-lactone. Chemically, it is a member of the class of compounds known as furanolactones.

Limonin is enriched in citrus fruits and is often found at higher concentrations in seeds, for example orange and lemon seeds. Limonin is also present in plants such as those of the Dictamnus genus.

Limonin and other limonoid compounds contribute to the bitter taste of some citrus food products. Researchers have proposed removal of limonoids from orange juice and other products through the use of polymeric films.
