Abstract

ABSTRAK Virgin Coconut Oil (VCO) merupakan produk olahan kelapa tanpa pemanasan. VCO merupakan produk yang memiliki aktivitas antioksidan. Tujuan penelitian yaitu menguji aktivitas antioksidan Virgin Coconut Oil yang diberikan pencahayaan. Sistem fotooksidasi menggunakan kota cahaya yang dimodifikasi menggunakan lampu fluorescen. Fotooksidasi VCO menggunakan eritrosin sebagai sensitizer. Aktivitas antioksidan diuji menggunakan metode penangkalan radikal bebas DPPH, selanjutnya nilai IC50 ditentukan menggunakan analisis probit. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi VCO maka aktivitas antioksidan akan semakin tinggi, nilai IC50 sebesar 12,02%. Aktivitas antioksidan Virgin Coconut Oil yang dicahaya selama 7 jam mengalami menurunan menjadi 96,13%. Larutan VCO yang mengandung eritrosin mengalami penurunan absorbansi sebesar 0,121 selama proses fotooksidasi. Kesimpulan penelitian ini ialah cahaya menyebabkan reaksi fotooksidasi sehingga menurunkan aktivitas antioksidan VCO.ABSTRACT Virgin Coconut Oil is a coconut processed product without heating.

Photooxidation system using a modified light box of fluorescent light, while its antioxidant activity was tested using the DPPH free radical scavenging method, the IC50 value was determined using probit analysis. The results showed that the higher the VCO concentration, the higher the antioxidant activity. Antioxidan activity of Virgin Coconut Oil that is exposed to light decreased to 96.13%. The absorbance of VCO solution containing erythrosine as sensitizer decreased to 0.121 due to photooxidation. The conclusion of this study is that light will cause a photooxidation reaction, thereby reducing the antioxidant activity of VCO.

光氧化对处女椰子油的抗氧化剂活性的影响

原始椰子油(VCO)是一种没有加热的精制椰子产品。VCO是一种有抗氧化剂活性的产品。这项研究的目的是测试照明的抗氧化物处女椰子油的活性。光氧化系统使用经过改建的照明系统使用荧光灯。VCO利用红霉素作为感受器。反氧化活性使用DPPH自由反氧化方法进行测试，然后用probit分析确定IC50值。研究结果表明，VCO浓度越高，抗氧化剂活性就越高，IC50为12.02%。7小时内处女椰油的抗氧化剂活性下降到96.13%。在光合作用过程中，VCO含有eritrosin的吸收率下降了0.121。研究的结论是，光会引起光合作用，降低抗氧化剂和VCO的活动。未经加热的加工过程产物是一个不进行加热的过程。VCO是一种制毒活动。这项研究的目标是测试一盏灯下的处女椰子油的抗氧化剂作用。photooxixisystem采用了一种修饰的光盒的光，而它的抗氧化剂行为采用了DPPH自由放射scavengd的方法，而IC50值正在确定使用probit analysis。最近的人指出，VCO的浓度越高，反有毒活动就越高。处女椰子油的反oxiand activity，表示灯de奶油到96.13%。VCO解决方案的消毒液消毒。这项研究的结论是，由于一种磷酸反应，即减少VCO的抗氧化剂作用。
