Abstract
Penelitian bertujuan untuk mengetahui karakteristik fisik dan kimia permen jelly sari isi dan empulur buah nanas (Ananas comosus (L.) Merr.) berdasarkan tingkat penambahan konsentrasi gelatin yang berbeda. Faktor perlakuan dianalisis dengan metode Rancangan Acak Lengkap (RALF) Faktorial dengan 2 faktor perlakuan sari isi dan empulur buah nanas 90%, 86%, 82%, 78%, dan 74% dan taraf konsentrasi gelatin 10%, 14%, 18%, 22%, dan 26% serta perlakuan diulang sebanyak 2 kali. Penelitian menggunakan parameter karakteristik fisik (kekenyalan dan warna) dan karakteristik kimia (kadar air, kadar abu, kadar gula reduksi, dan aktivitas antioksidan). Hasil penelitian menunjukkan penambahan gelatin berpengaruh nyata terhadap kekenyalan, warna, kadar air, kadar abu, dan aktivitas antioksidan serta berpengaruh tidak nyata terhadap kadar gula reduksi. Perlakuan A1B4 dan A2B4 sari buah nanas 78% dan konsentrasi gelatin 22% merupakan perlakuan terbaik berdasarkan karakteristik fisik dan karakteristik kimia. Perlakuan A1B4 dan A2B4 mendapatkan hasil kekenyalan, warna, kadar air, kadar abu, kadar gula reduksi, dan aktivitas antioksidan berturut-turut sebesar 683,9% ; 749,9%, 45,8% ; 44,5%, 16,4% ; 16,2%, 29,18% ; 29,12%, 15% ; 14,9, 0,54% ; 0,29%, 26,7% ; 26,2%, 7,2% ; 6,1%. Uji aktivitas antioksidan permen jelly sari isi dan empulur buah nanas dengan variasi konsentrasi gelatin menghasilkan nilai IC50 dibawah 50% sehingga dapat dinyatakan bahwa aktivitas antioksidan pada permen jelly kuat.
