Current responsibilities:

  • Biochemical studies on sucrose accumulation in sweet sorghum for efficient ethanol production in sweet sorghum (NFBSFARA project upto 2016 as a PI)
  • Studies on the therapeutic properties and establishing millets as a functional and health food (DBT project as a PI upto 2020)
  • Research responsibilities on sorghum health foods in sorghum in XII plan
  • Studies on 1st and 2nd generation fuel ethanol from sweet sorghum

Recent 3 major contributions:

  • Contributed for the release of the first public sector hybrid of sweet sorghum CSH 22 SS and variety CSV 24SS after establishing the commercialization of use of sweet sorghum cane for fuel ethanol production (Renuka Sugar factory, Belgaum, Karnataka, 2003, Sagar sugars Pvt. Ltd, Nelavoy, Chittoor Dt.2005 and EID parry India pvt ltd, Srikakulam, 2016). Identified suitable microbial cultures, Candida tropicalis and Saccharomyces cerevisiae (amylolytic strain) for fermentation of sweet sorghum juice
  • Developed process for making poha (beaten sorghum) from sorghum using rice flaking machine , extruded sorghum (pasta and vermicelli)and preconditioning of grain for the preparation of pops
  • High antioxidant activity measured as Ascorbic acid equivalent antioxidant activity (AEAA) and DPPH activity was standardized and measured in 127 genotypes and 33 genotypes are with high AEAA activity. Out of these 10 genotypes are having high polyphenolic content also. They are IS 29241, EP 20, IS 28614, SPV 1745, IS 24462, EP 105, IS 14861, IS 30572, IS 19445 and IS 28313.
