to 1→4 or 1→6 glycosidic linkage, respectively, which might becaused by the complexity of spatial structure of those two starches.Absence of peak at 4.5 ppm, diminishing of the peak at 4.3 ppm andstrengthening in intensity of the peaks at 3.6, 3.3 ppm demonstratethat H-2, H-3, and H-5 ofstarch mightinvolve in starch grafting andbring forth new terminal 1→2, 1→3 or1→5glycosidiclinkagesduring frozen process. The chemical shifts of those new linkagesoverlap those of C-4 and C-6. Further research should be carriedout to uncover the pattern of the grafting.
