| Research Abstract |
The seeds of Karin (Chaenomelese sinensis), usually discarded, are surrounded with transparent mucilage, which appears readily extractable with water to give hydrocolloidal solution. We report the structural features of Karin seed-surface mucilage and its colloidal characteristics. The structural feature of Karin seed-surface mucilage was assumed as O-2-substituted D-glucurono-L-arabino-(1→4)-ss-D-xylan. This unique seed-surface mucilage may be built up with the above acidic polysaccharide and D-xylo (1→4)-ss-D-glucan, associated by intermolecular hydrogen bonding. Fibrous form cellulose was not found by hydrolysis of the Karin mucilage, not like quince. The thixotropic behavior and water-holding capabilities of the mucilage show Karin seed mucilage is appreciable to food additives and cosmetic utilization, such as lotion.
