Isolation of pectin-enriched products from red beet (Beta vulgaris L. var. conditiva) wastes: Composition and functional properties
The present work was dedicated to the development of an extraction process for red beet (Beta vulgaris L. var. conditiva) by-products that preserves the high molecular weight of the macromolecules with the primary aim of waste upgrading. Our study concerns the extraction of pectin-enriched products...
