Standardisation of natural dye powders via spray drying: initial physicochemical characterisation
Liquid natural dyes exhibit some drawbacks in terms of storage, distribution, dosage control, and quality consistency. This study aimed to evaluate the initial standardisation of natural dye powders from the bark of Tingi (Ceriops tagal), wood of Tegeran (Cudrania javanensis), and leaves of Indigofera (Indigofera tinct...
