VEGETABLE OILS TECHNICAL

Introduction

The domestic production of 11 oilseed crops is being outstripped by growing demand for edible oils. The Agriculture

Ministry had estimated a shortage of about 1.4 million tonnes of edible oils both in 1996-97 and 1997-98 which was

expected to rise to 2.2 million tonnes by the year 2000. Figures however show that the actual imports was

approximately 4.3 million tonnes for 1998-99 and is estimated at about 5.0 million tonnes in 1999-2000.
