dc.description.abstractDendeng berpotensi mengalami reaksi oksidasi yang dapat dihambat dengan antioksidan. Senyawa antioksidan banyak terkandung dalam bahan alami, seperti bunga rosella. Penelitian ini bertujuan untuk menguji sifat fisikokimia, organoleptik dan aktivitas antioksidan dendeng daging ayam dengan penambahan serbuk bunga rosella. Variabel yang diukur dalam penelitian ini meliputi nilai pH, aw, kadar air, aktivitas penghambatan terhadap 2,2-difenil-1-pikrilhidrazil (DPPH), kapasitas antioksidan, nilai TBARS, dan sifat organoleptik (warna, aroma, tekstur, dan rasa) dendeng daging ayam. Rancangan yang digunakan dalam penelitian ini adalah rancangan acak lengkap (RAL) dengan tingkat penambahan serbuk bunga rosella yang berbeda (0%; 0,15%; 0,30%). Hasil penelitian menunjukkan bahwa penambahan serbuk bunga rosella berpengaruh nyata (p<0,05) terhadap nilai pH yang semakin menurun, serta nilai aw dan kadar air yang semakin meningkat. Penambahan serbuk bunga rosella tidak berpengaruh nyata terhadap nilai TBARS, aktivitas penghambatan DPPH dan kapasitas antioksidan. Secara keseluruhan dendeng daging ayam dengan penambahan serbuk bunga rosella pada taraf 0,15% dan 0,30% tidak memberikan pengaruh terhadap sifat fisikokimia, organoleptik, dan aktivitas antioksidan.id
dc.description.abstractJerky has the potential to undergo oxidation reactions that can be inhibited by antioxidants. Many antioxidant compounds are contained in natural ingredients, such as rosella flowers. This study aimed to examine the physicochemical, organoleptic, and antioxidant activity of chicken meat jerky with the addition of roselle flower powder. The variables measured in this study included pH value, aw, moisture content, inhibition of 2,2-diphenyl-1-picrylhydrazyl (DPPH), antioxidant capacity, TBARS value, and organoleptic properties (color, aroma, texture, and taste) of chicken meat. The jerky design used in this study was a completely randomized design (CRD) with different levels of rosella flower powder addition (0%; 0.15%; 0.30%). The results showed that the addition of rosella flower powder had a significant effect (p<0.05) on the decreasing pH value and increasing water content. The addition of rosella flower powder did not significantly affect the TBARS value, DPPH inhibitory activity and antioxidant capacity. Overall chicken jerky with the addition of rosella flower powder at the level of 0.15% and 0.30% did not affect the physicochemical, organoleptic, and antioxidant activity properties.id
