“…The drawbacks of conventional approaches, such as time-consuming methods, safety risks with some hazardous solvent systems, contaminated product, and comparatively less yields, have increased the demand for the novel processing methods Reaction which confirmed the presence of vinylene connecting group. [16,17]. To improve the betalain extraction, some of the pretreatment methods have been proposed, such as pulsed electric fields [18], gamma irradiation [8], and low-direct current electric fields [19].…”

“…But, such methods are quite expensive when compared to the solvent extraction techniques. Further, certain nonthermal techniques, like ultrasound (sonication) processing, and microwave-assisted extractions are also significantly productive in order to enhance the extraction yields of bioactive molecules with minimum degradation [17].…”

“…The ratio of color contents is decisively influenced by specie source, genetic, cultivar, or the environment of cultivation throughout growing, and the stages of harvesting [4,12,13]. Practically, one kilogram of fresh beetroot contains 300-600 mg of betacyanin and 320-420 mg of betaxanthin [14]; compared to the flesh, betalain concentration ranges from 40 to 70% higher in the peel and it also depends on genotypes [15].…”

“…No Esquema 5 são apresentadas algumas vias de degradação de betacianinas, bem como os principais agentes para estas transformações. 48 Além de descarboxilação, desidrogenação e desglicosilação, as betalaínas ainda podem sofrer hidrólise, dando origem ao precursor ácido betalâmico e a amina correspondente. Na presença de ácido, pode ocorrer epimerização, dando origem às isobetalaínas, e abertura do anel 1,2,3,4-tetraidropiridínico, levando à formação de 4,5-seco-DOPA.…”
