Morphology and Distribution of Starch Granules from Trunking and Non-Trunking Sago Palm (Metroxylon sagu)

Sago palm (Metroxylon sagu) naturally grows in Malaysia and this species covers a large area in the state of Sarawak. The starch of sago palm is in its trunk. Sago palm is one of the oldest tropical plants exploited by man for its stem starch and one of the main starch-producing crops in the world....

The starch of sago palm is in its trunk. Sago palm is one of the oldest tropical plants exploited by man for its stem starch and one of the main starch-producing crops in the world.

The shape of the starch granules for trunking sago palm trunk was the same as non-trunking sago palm trunk, where the shape was oval and truncated. The average size of starch granules from trunk of both trunking and non-trunking sago palm are around 20-40 μm. The starch granules extracted from trunking and non-trunking sago palm leaves have disc shaped and oval, where the size of granules range between 1-5 μm. In TEM, the growth rings formation in the trunk of trunking and non-trunking sago palm were the same; they were made up of alternating amorphous and semi-crystalline layers.
