Designation: 
Principal Scientist ( Horticulture)
Division/Section: 
Division of Post Harvest Technology and Agricultural Engineering
Specialisation: 
Post Harvest Technology- Processing of fruits and vegetables through osmotic dehydration,vacuum impregnation, osmodehydrofreezing
Qualification: 
M. Sc. Ag. (Hort), PhD
Experience (No. of Years): 
21
Research Accomplishments: 

Research experience 21years. The main research emphasis has been nutrient retention and evaluation of quality during processing and storage of processed products, blending of fruit juices and pulps to improve quality, retention of carotene and lycopene during vacuum concentration of mango and tomato pulps/juice respectively and dehydration and freezing of vegetables. Screening of fruits and vegetables varieties/hybrids for processing qualities. Present research interest are osmotic dehydration of fruits like mango and pineapple,papaya,banana,guava,jackfruit,aonla, vegetables carrot and pumpkin development of value added dried products from vegetables such as carrot, cauliflower, onion, French beans. Freezing preservation of vegetables and dehydro-freezing of fruit slices. Recent research interest is vacuum /pressure assisted osmotic dehydration of fruits and vegetables
