The present investigation was intended to characterize pigments for the first time from Rhodotorula taiwanensis (LC011412) yeast isolated from the ethic fermentation starter culture source meant to evaluate its carotenoid contents for beneficial applications. The pigments were extracted by an optimized solvent system, purified by flash chromatography and were identified by TLC and UV/VIS spectroscopy. The absorbance spectra confirmed the presence of β‐carotene, β‐cryptoxanthin, torulene and torularhodin that showed maximum absorbance (λmax) within the ranges. The fractions were further characterized by LC/MS and analyzed through FT‐IR and NMR for structure elucidation. Spectral analyses also confirmed the presence of the compounds mentioned above. These compounds promise great commercial value and could be useful for large scale production anticipated for potential applications in food, nutraceutical, pharmaceutical and cosmetic sectors. It is pertinent that the characterized carotenoid pigments from the isolate have incredible prospects in industrial applications which require profound attention.
