      Abstract
      Marinasi daging sapi dengan bahan tinggi antioksidan umum digunakan untuk menghambat terjadinya oksidasi yang dapat menghasilkan senyawa toksik, seperti malondialdehida (MDA). Penelitian bertujuan menganalisis pengaruh penambahan kecombrang pada bumbu dengan lama marinasi 12 atau 24 jam terhadap sifat fisikokimia, aktivitas antioksidan dan MDA daging sapi panggang. Rancangan yang digunakan adalah rancangan acak kelompok (RAK) 2 faktor, dengan faktor pertama, yaitu penambahan bumbu marinasi (tanpa bumbu marinasi (kontrol), 0%, dan 10% bunga kecombrang) dan faktor kedua waktu marinasi (12 atau 24 jam). Hasil penelitian menunjukkan bahwa penambahan bumbu marinasi berpengaruh secara nyata terhadap pH, aktivitas antioksidan dan kapasitas antioksidan (p<0,05). Penggunaan bumbu marinasi dengan ataupun tanpa bunga kecombrang menghasilkan penurunan pH dan peningkatan aktivitas antioksidan dibanding kontrol (p<0,05). Lama waktu marinasi nyata meningkatkan pH daging sapi panggang (p<0,05). Kadar air, aktivitas air (aw) dan kadar MDA tidak menunjukkan perbedaan nyata akibat perlakuan yang diberikan. Kesimpulannya, lama marinasi baik dengan atau tanpa bunga kecombrang lebih efisien dilakukan selama 12 jam.
       
      Marinating beef using high antioxidant ingredients is commonly used to inhibit oxidation which can lead to forming toxic compunds, such as malondialdehyde (MDA). This study aims to determine the effect of adding marinade and torch ginger flower with marinating time of 12 or 24 hours on physicochemical properties, antioxidant activity and MDA value of grilled beef. This study used two factor completely randomized designs (CRD) with three treatments marinade formulas (without marinade, 0%, and 10% torch ginger flower) and marinating times (12 or 24 hours). The result showed that the addition of marinade significantly effected pH value, antioxidant activity and antioxidant capacity (p<0,05). The addition of marinade with or without torch ginger flower decreased the pH value and increased the antioxidant activity than the control (p<0,05). Marinating time significantly increased pH value of grilled beef. Water content, water activity (aw) and MDA value did not show any significant differences due to the treatment given. So, 12 hours marination with or without torch ginger flower showed the best result.
