Abstract: | Betalains have been widely used as natural colorants for many centuries, but their attractiveness for use as colorants of
foods (or drugs and cosmetics) has increased recently due to their reportedly high anti-oxidative, free radical scavenging
activities and concerns about the use of various synthetic alternatives. The main commercial sources of betalains are powders
and concentrates of red beet (Beta vulgaris) or cactus pear (Opuntia ficus-indica) extracts. However, in recent years the technical and commercial feasibility of various in vitro systems to produce them
biotechnologically has been explored. These research activities have included assessments of novel approaches for cultivating
plant cell or tissue cultures, and diverse bioreactor systems for increasing production levels of secondary metabolites. This
paper reviews recent progress in plant in vitro systems for producing betalain pigments. In addition, the factors that could
be manipulated, the bioreactor systems that could be used, and the strategies that could be applied to improve betalain production
are discussed. |
