Effects of various drying methods on the vitamin C level of papaya locally grown in Brunei Darussalam
Nur Amirah Hair Mustapa1, Siti Rohaiza Ahmad2.
Papaya (Carica. papaya L.) belongs to the Caricaceae family. They are grown in almost
all tropical and subtropical regions in the world. In Brunei Darussalam, papaya is a nonseasonal
fruit that is locally grown. It is also common to dry papaya. Drying is the process
of removing water or moisture from a product with the benefit of improving shelf-life by
impeding food spoilage by microorganisms. In this research, freshly ripened papaya was
subjected to various drying methods and its effect on the vitamin C levels was investigated.
The drying methods include sun drying (SD), oven drying (OD), freeze-drying (FD) and
deep freezing (DF). Fresh samples were also investigated and acted as the control. The
determination of vitamin C levels was carried out using an accredited Association of
Official Agricultural Chemists (AOAC) indophenol titrimetric method. The result showed
that FD samples had the highest vitamin C levels (5.84 ± 0.83 mg/100g) while SD has the
least value of vitamin C (2.96 ± 0.47 mg/100g). In conclusion, the FD method resulted in
highest vitamin C levels. Therefore, the FD method serves as the best industrial application
with good vitamin C retention in papaya.
