Keywords: Proximate analysis, Antioxidant, Gingerol, Shing and Nadia ginger (Zingiber officinale Roscoe)
In the north-eastern part of India, ginger (Zingiber officinale Roscoe) is one of the prominent and widely cultivated cash crops. In Manipur, apart from standard cultivar like Nadia, local cultivars, Shing is a part of everyday local cuisine. A proximate analysis and antioxidant property of the two cultivars of ginger (Nadia as standard cultivar and Shing as local cultivar) were studied. It was observed that the Local Shing (ginger) has more fibre content than the Nadia ginger. The pungency in ginger is related to the content of gingerol. Gingerol and its related compound are well known for imparting pungency and have several pharmacological properties. The local cultivar is found to have high content of 6-gingerol which results in having high pungency quality making it a popular aromatic crop. Nadia ginger has less fibrous rhizome with lemony flavour and has more concentration of phenol, flavonoids, tannins content and high antioxidant activity.
