Penelitian ini mengevaluasi perubahan mutu selai bunga rosella dan jahe selama
penyimpanan serta menelaah pendugaan umur simpannya dalam kerangka Accelerated
Shelf Life Testing (ASLT). Lima perlakuan penambahan jahe terdiri atas N1 0 g, N2 5 g, N3
10 g, N4 15 g, dan N5 20 g. Parameter yang disajikan meliputi pH, total padatan terlarut,
warna, tekstur, aroma, dan rasa. Data dianalisis secara deskriptif dari tabel hari ke-0 dan
ke-31 serta grafik mingguan. pH awal berkisar 3,40–3,74 dan total padatan terlarut 65,7
74,7 °Brix. Skor keempat atribut sensori menurun pada seluruh perlakuan antara hari ke-0
dan ke-31. Penolakan yang dilaporkan pada hari ke-31 mencapai 75,83%, sedangkan
dokumentasi minggu ketiga menunjukkan pertumbuhan yang menyerupai kapang. Estimasi
14 hari pada suhu 24–25 °C dipertahankan sebagai dugaan awal. Tanpa data suhu
percepatan, konstanta laju, energi aktivasi, dan batas mutu kritis, estimasi tersebut belum
dapat diverifikasi sebagai prediksi Arrhenius maupun batas keamanan pangan
