ABSTRACT
Baccaurea angulata or locally known as ‘belimbing dayak’ or
‘belimbing hutan’ is an underutilized fruit indigenous to Borneo with
its proximate analysis and antioxidant values are yet to be explored. Proximate
analysis and antioxidative properties of oven-dried B. angulata fruits
of three fractions; whole fruit, skins and berries were evaluated. From the
analysis conducted, whole fruit, berries and skins fraction of B.
angulata contained 2.83%, 5.15% and 0.28% of total fat; 3.11%, 3.43% and
3.89% of protein; 16.66%, 19.09% and 11.37% of moisture; 4.57%, 3.68% and 7.28%
of total ash and water activity (Aw) of 0.41, 0.44 and 0.44, respectively. Evaluation
of antioxidant activities using ferric reducing ability of plasma (FRAP),
1,1-diphenyl-2-pycrylhydrazyl (DPPH) and Trolox/ABTS equivalent
antioxidant capacity (TEAC) revealed that the skins fraction
exhibits highest antioxidant activities (p<0.05) followed by whole fruit and berries fractions. The
antioxidant activities were significantly correlated (p<0.05) with
total phenolic and total flavonoid content but not to anthocyanins. Considering
the nutritional values it contained, B. angulata is another good
source of natural antioxidants with significant health benefits and high value
for commercialization.

ABSTRAK
Baccaurea angulata atau lebih dikenali sebagai belimbing dayak atau belimbing hutan oleh masyarakat tempatan
merupakan sejenis buah yang tergolong dalam buah-buahan nadir dan berasal dari
Borneo. Makronutrien dan bahan antioksida yang
terkandung di dalam buah ini masih belum dikaji. Analisis proksimat dan
ciri-ciri bahan antioksida yang terkandung di dalam tiga pecahan buah B.
angulata, iaitu keseluruhan bahagian buah, bahagian kulit dan bahagian isi
buah telah dijalankan. Ketiga-tiga pecahan tersebut terlebih
dahulu dikeringkan dengan menggunakan ketuhar. Hasil analisis
menunjukkan bahawa keseluruhan bahagian buah, bahagian kulit dan bahagian isi
buah B. angulata masing-masing mengandungi 2.83%, 5.15% dan 0.28% jumlah
lemak; 3.11%, 3.43% dan 3.89% protein; 16.66%, 19.09% dan 11.37% kelembapan;
4.57%, 3.68% dan 7.28% jumlah abu dan 0.41, 0.44 dan 0.44 aktiviti air (Aw).
Penilaian aktiviti antioksida menggunakan ujian kebolehan penurunan ferum pada
plasma (FRAP),
ujian 1,1-difenil-2-pikrilhidrazil (DPPH) dan ujian kapasiti antioksida setara
Trolox/ABTS (TEAC) menunjukkan aktiviti antioksida yang
paling tinggi (p<0.05) pada
bahagian kulit diikuti dengan bahagian keseluruhan buah dan bahagian isi buah. Aktiviti antioksida tersebut secara signifikan (p<0.05)
berkorelasi dengan kandungan jumlah fenol dan flavonoid, tetapi tidak dengan
antosianin. Justeru, dengan nilai nutrisi yang terkandung dalam B.
angulata tersebut, ia boleh dianggap sebagai antara sumber bahan antioksida
semulajadi yang baik untuk kesihatan dan mempunyai nilai komersial yang tinggi.
