Oil content analysis in oilseed crops requires methods that are non-destructive, accurate, fast, eco-friendly (without the use of solvent), inexpensive in terms of consumables, and easy to use. Pulsed low-resolution nuclear magnetic resonance (NMR) satisfies all these conditions. The objective of the present study was to develop an oil measurement method for seeds using NMR spectrometry. A bench-top pulsed NMR analyser was calibrated with respect to temperature. Six genotypes each of sunflower, safflower and castor were used for the analysis. Changes in sample conditioning temperature can lead to significant changes in the calibration graph. Based on the statistical parameters (correlation coefficient, variance and standard deviation) obtained, the best calibration was found for sunflower and safflower at 40°C and castor at 44°C among the temperature ranges tested.Keywords

To analyse the domestic consumption pattern of vegetable oils, ICAR-Indian Institute of Oilseeds Research, Hyderabad, undertook an online survey through Google forms. The survey aimed at generating estimates of average household monthly per capita consumption of vegetable oils, distribution based on urban or rural households, average consumption by income groups, most preferred type of oil and brand by consumers, crop-wise percentage of consumers, food habits and consumption of the same oil or multiple oils throughout the year. Results indicated that rural households consumed 15.6 kg of oil per person per annum, whereas urban households consumed 12.4 kg. Non-vegetarians (64%) consumed 14.2 kg of oil per person per annum, whereas vegetarians (36%) consumed 12.6 kg. Mustard oil was most preferred in the north (61%) and east (35%) zones of India, followed by sunflower oil. About 28% of people in the west zone consumed soybean oil, followed by mustard oil (25%) and sunflower (25%) oil. Sunflower oil (44%) was the most popular oil in the southern zone, followed by groundnut oil (29%). Total per capita consumption of oil, including other purposes, was 14.43 kg per annumKeywords
