Increment in drying temperature led to significant reduction of betacyanins and betaxanthins in pitaya peels, which is consistent with Mello et al.
The temperature of 50[degrees]C would be the most adequate for pitaya peel drying, because it retains high concentrations of betacyanins and betaxanthins, which highlights its potential to be used by industries to replace artificial dyes, promoting benefits to health, such as antioxidant activity.
A class of water soluble nitrogen containing plant pigments of the order Caryophyllales which consists of the yellow betaxanthins and the violet betacyanins (Gandia-Herrero, Escribano, & Garcia-Carmona, 2005; Yusuf, Shabbir, & Mohammad, 2017).
The cultivation media known as M1 and M2 were more efficient in the production of betaxanthins.
Additionally, previous studies reported a superior stability of betacyanins in comparison to betaxanthins
In contrast, beetroot extracts show a second absorption peak at about 480nm, which is characteristic of yellow betaxanthins
(VAILLANT et al.
tricolor) is rich in natural colorants such as carotenoids, betaxanthins
and anthocyanins (Cai et al.
The yellowish pigments that give the visible glow are called betaxanthins
Betalaines, another class of naturally occurring pigments found in beets, contain betacyanins, which are red, and betaxanthins
, which are yellow.
The Findings: Beets (except white varieties) contain water-soluble pigments called betalains, composed of the redpurple betacyanins and the yellow-orange betaxanthins
as pigments responsible for visible fluorescence in flowers.
1997), which are composed of two main groups: the red betacyanins and the yellow betaxanthins
