Sunflower defatted meal is a good source of protein of nutritional quality. The defatted meal of the whole seed contains about 24.02+2.27 Vo hull and 75.35+2.1,7 Vo endosperm, with an endosperm to hull ratio of 3.17+0.38. The fibre content in the defatted meal amounts to 29.83+4.03 7a, out of which 17.18+2.1,4 7o is contributed from the hull alone, and the ratio of fibre content in the hull to kernel is 1.42+0.25. The results of the germination studies indicate that there is a gradual degradation of the globulins, glutelins, and prolamines in uilro, followed by a concomitant increase in the albumins after the third day of germination. IVPD analysis shows that the fibre content has hardly any effect on the protein digestibility by pepsin + pancreatin.
