Monascus pigments (MPs) are important azaphilone-type polyketide pigments, yet yield control, stability, and safety pose challenges. Using an epigenetic derepression strategy, we constructed an Ash2 deletion mutant in th...

ObjectiveThe method of high performance liquid chromatography （HPLC） was developed to study the detection of synthetic colorants in natural pigments and condiment.MethodsThe analytes were extracted by direct ultrason...

This research delves into ancient pigment practices among the Goya-Malabrigo societies in the Upper Delta of the Paran a River during the Late Holocene. Utilising Raman microspectroscopy and X-ray diffraction, we analyse...

Ochre pigments, in all their varieties, have played a key role in Northwestern Argentinian pottery for more than 2000 years. Present in different styles, they are combined with other colours on surface paints. This artic...

X-ray diffraction analyses of five samples of pigments from a recently excavated mural at the archaeological site of Huaca Tacaynamo, a part of the Chan Chan archaeological complex, northern Peru, show that minerals rela...
