| description | Gaining sustainability in the textile finishing industry deals among others with the replacement of synthetic dyes with non-toxic and biodegradable natural dyes. Lately, increasing preoccupation has been noticed with the reassessment of the North America and Europe flora, as potential resources for extraction of natural colorants. Within the wide range of natural colorants, anthocyanins - found in fruits and vegetables, dye natural fibers in beautiful pink and purple shades. Chokeberry (Aronia melanocarpa) fruit, ordinarily used as a nutraceutical, has one of the highest contents of anthocyanins in the plant kingdom. This paper deals with the extraction of anthocyanins from dried chokeberry fruits and pomace, using a conventional solvent extraction with acidulated acetone-water mixture and a non-conventional aqueous two-phase extraction based on salt-alcohol mixtures. The anthocyanins extraction yield from chokeberry fruits was very low and had comparable values for both extractants, of around 70 mg/100 g dried fruit. Pomace had a much higher anthocyanins content, namely 876.37 mg/100 g dry pomace for the acetone extractant and 1287.2 mg/100 g dry pomace for the two-phase extractant. Anthocyanins’ color and stability showed an expected variation when the solution pH shifted from acidic to alkaline. Aronia juice extraction leftovers can be turned from a potential waste into a valuable and easily available source of natural dyes. |
