Synergistic enhancement of in-vitro antioxidant activity in essential oil and post-distillation residue-derived oleoresin combinations of Zingiber officinale cultivars and development of a microencapsulated antioxidant rich controlled release nutraceutical

Abstract

Two widely cultivated ginger cultivars in Sri Lanka, named Ceylon and Rangoon (Zingiber officinale) were investigated to develop a valorized, high potency microencapsulated nutraceutical from ginger processing by-products.
