“…Beyond the red-violet amaranthin and its C 15 -epimer isoamaranthin, the authors reported the production of new pigments belonging to the betaxanthins’ group: methyl derivative of arginine-bx and an unidentified betaxanthin. The production of betacyanins by seedlings obtained from callus cell line of A. tricolor was also reported and positively influenced by light and cytokinins [ 131 ]. The expression of five betalains’ biosynthesis genes was modulated by phytohormones but there are presumably also other factors that influence betalain production [ 132 ].…”

Natural pigments are largely distributed in the plant kingdom. They belong to diverse groups, with distinct biochemical pathways. Betalains with colours that range from yellow to red-violet can de divided into two main subgroups: betaxanthins and betacyanins. These types of pigments are confined into 13 families of the order Caryophyllales and in some genera of higher fungi (Amanita muscaria, Hygrocybe and Hygrophorus). The Amaranthaceae family includes diverse genera in which betalains are present: Alternanthera, Amaranthus, Beta, Chenopodium, Celosia and Gomphrena. The biosynthesis of betalains and their general biological properties were reviwed in the present work. In addition, the types of betalains present in some species of the aforementioned genera, their stability and production, as well as biological attributes, were reviewed.

“…UV-and red-light-induced betalain synthesis appears to be mediated by phytochrome via gene activation [469]. Cytokinins have also been shown to promote betalain biosynthesis, presumably also via gene activation, even in the dark [470,471]. The…”

Preface to the second editionIn this second edition of Natural Food Colorants two new chapters have been added and we have taken the opportunity to revise all the other chapters. Each of the original authors have brought up to date their individual contributions, involving in several cases an expansion to the text by the addition of new material. The new chapters are on the role of biotechnology in food colorant production and on safety in natural colorants, two areas which have undergone considerable change and development in the past five years. We have also persuaded the publishers to indulge in a display of colours by including illustrations of the majority of pigments of importance to the food industry. Finally we have rearranged the order of the chapters to reflect a more logical sequence. We hope this new edition will be greeted as enthusiastically as the first.It remains for us, as editors, to thank our contributors for undertaking the revisions with such thoroughness and to thank Blackie A&P for their support and considerable patience.

“…The pigment can be induced by light and rapid synthesis can occur within 24 h after irradiation, but disappear in the dark due to pigment degradation and proliferation of white cells. Most in vitro studies have shown evidence for some effects of light on the accumulation of betalain pigments in cultured cells (Bianco-Colomas & Hugues 1990;Boehm etal. 1991), although the details of the light responses have not yet been clarified.…”

The wavelength range that activates betalain pigmentation has been studied following selection of light inducible betalain producing callus lines originating from Portulaca sp. 'Jewel' seedlings. Light sources with different wavelengths were used to irradiate the callus, resulting in blue light being effective in inducing betalain pigmentation. In addition, when UV light was combined with blue light, some calluses from this cell line showed high production of the pigment. This is a first report that betalaln pigmentation in callus was induced by blue and blue/UV lights.
