The ability of pomegranate extracts

The ability of pomegranate extracts to inhibit β-carotene bleaching was estimated according
to the method explained by Maria et al. (2010) with minor modifications. β-
Carotene/linoleate emulsion was prepared by mixing 10 mg of β-carotene, 40 mg of linoleic
acid, 600 mg of Tween 20 emulsifier and 100 mL of oxygenated deionized water. The so
prepared emulsion (2 mL) was mixed with 200 µL of extracts and incubated at 50oC. The
oxidative loss of emulsion was monitored using a UV visible spectrophotometer (UV 1601,
Shimadzu, Japan) at 470 nm wave length at every 15 minute for 120 minutes. The

Kemampuan ekstrak delima untuk menghambat β-karoten pemutihan diperkirakan sesuai
dengan metode yang dijelaskan oleh Maria dkk. (2010) dengan sedikit modifikasi. β-
karoten / linoleat emulsi dibuat dengan mencampur 10 mg β-karoten, 40 mg linoleat
asam, 600 mg Tween 20 emulsifier dan 100 ml air deionisasi oksigen. Sehingga
emulsi siap (2 mL) dicampur dengan 200 uL ekstrak dan diinkubasi pada 50oC. The
kerugian oksidatif emulsi dipantau menggunakan UV spektrofotometer terlihat (UV 1601,
Shimadzu, Jepang) di 470 panjang gelombang nm pada setiap 15 menit selama 120 menit. The
