摘要：

Edible grade meal was prepared from dehaulled and defatted and sunflower seed kernels and analyzed for proximate principles, polyphenols and phytate and its nitrogen extractability was studied at different variables. The kernels contained 19.8 % proteins, 50.1% fat, 3.7 % ash, 1.6 % polyphenols and 1.7 % phytate on dry weight basis. Dehulling kernels increased relative concentrations of these components on unit weight basis. A solid: liquid ratio of 1:20 and extraction time of 30 min were found to be the most optimum nitrogen solubilizing parameters. Addition of sodium chloride increased the nitrogen extractability in isoelectric pH range.
