Concentrations of Beetroot (Beta vulgaris L.) Peel and Flesh Extracts by Reverse Osmosis Membrane

The objective of this investigation was to concentrate betalains, phenolics, and antioxidants from the extract peel flesh beetroot (Beta vulgaris L.). Thin-film composite reverse osmosis (RO) membrane composed thick polyamide barrier layer, microporous polysulfone interlayer, polyester support web used in module. In a later exercise, thermo-instability betalain color compounds investigated with different temperatures. After filtration aqueous flesh, betacyanins, betaxanthins, total betalains were increased by 5.2, 6.1, 5.5 times, respectively. Likewise, mentioned bioactive 3.7, 4.9, 4.2 times after peel. amounts measured final two lower (14.33 ± 0.15 mg·g−1 dm) compared (30.02 0.28 dm). superior amount phenolic shown (34.47 0.19 mg GAE·g−1 (12.74 0.42 antioxidant activity 24.65 1.42 ASE·g−1 dm 11.6 0.1 dm, recovery thermo-sensitive bio-colorants achieved least thermal degradation.
