Optimization of ph and temperature stability from extraction of natural anthocyanins from seed of buah kundang (Bouea Macrophylla) for potential food colorant purposes / Nurfarah Nadia Abdul Mutalib

‘Buah Kundang’ (Bouea Macrophylla) is one of the abundance fruits in Malaysia comes from the family Anacardiaceae. The seed of ‘buah kundang’ is a potential sources of anthocyanin which responsible for the bright purple color. Anthocyanin also is a cell antioxidant activities which play vital part i...

The objectives of this study was to assess the stability of anthocyanin extract from the ‘buah kundang’ seeds.

In conclusion, the purple color extracted from the ‘buah kundang’ was not suitable for food coloring since it is no ability to withstand high temperature and only stable in quite an acidic condition. 2016 Student Project NonPeerReviewed text en http://ir.uitm.edu.my/id/eprint/45233/1/45233.pdf Abdul Mutalib, Nurfarah Nadia (2016) Optimization of ph and temperature stability from extraction of natural anthocyanins from seed of buah kundang (Bouea Macrophylla) for potential food colorant purposes / Nurfarah Nadia Abdul Mutalib.
