The Effect Of Physical Treatment And
Fermentation On Chemical And
Nutritional Composition Of Malaysian
Rubber Seed.
Masters thesis, Universiti Sains Malaysia.
Abstract
Rubber seed (Hevea brasiliensis) as a by-product from rubber plantations
contains nutritive values that can be harnessed as food for human, feed for animals or
fuel for energy. Chemical analyses and the highest yield from the screw pressed
rubber oil and rubber meal have been done in this study. The study continued to
evaluate chemical analyses from the best conditions of press parameters,
detoxification treatments to reduce HCN content on rubber seed using some methods
(heat treatment, storage, soaking, and fermentation).
Results showed that rubber seed can alternatively be considered as potential
feed stuff and good companion for maize as feed for animal. Essential amino acid of
rubber seed showed rubber seed high in Valine but low in Methionine. Fermentation
process is the best result to reduce HCN content among other treatments. There were
significant differences among detoxification treatments, which is the fermentation
process reduced more HCN content comparing other treatments.
