Abstract

Cascara Arabica merupakan kulit kering buah kopi Arabica yang umumnya disajikan dengan cara diseduh seperti teh, sehingga dikenal sebagai cascara tea. Cascara Arabica berpotensi dikembangkan lebih lanjut menjadi serbuk minuman instan sebagai upaya diversifikasi produk. Pembuatan serbuk instan dengan metode foam mat drying memerlukan penambahan gum arab sebagai bulking agent yang berperan menambah total padatan, meningkatkan volume, melapisi komponen rasa, serta melindungi bahan dari kerusakan akibat panas. Penelitian ini bertujuan mengkaji pengaruh rasio ekstrak air cascara Arabika dan gum arab terhadap karakteristik fisik dan kimia serbuk instan cascara Arabika. Penelitian menggunakan rancangan acak lengkap (RAL) satu faktor, yaitu rasio ekstrak air cascara Arabika dan gum arab, yang terdiri atas lima taraf perlakuan dengan empat ulangan, yaitu P1 = 95:5, P2 = 90:10, P3 = 85:15, P4 = 80:20, dan P5 = 75:25. Data yang diperoleh dianalisis menggunakan ANOVA untuk mengetahui adanya pengaruh perlakuan, kemudian dilanjutkan dengan uji DMRT pada taraf signifikansi 5% (α = 5%) guna membandingkan perbedaan antar perlakuan. Hasil penelitian menunjukkan bahwa penurunan proporsi ekstrak air cascara Arabica dan peningkatan proporsi gum arab cenderung menurunkan kadar air, kadar flavonoid total, densitas kamba, angle of repose, serta kelarutan (waktu larut) dalam air panas maupun dingin. Sebaliknya, perubahan rasio tersebut meningkatkan kadar abu dan aktivitas antioksidan serbuk instan cascara Arabica yang dihasilkan. Secara keseluruhan, perlakuan dengan rasio ekstrak air cascara Arabica dan gum arab 75:25 memberikan karakteristik fisik dan kimia terbaik untuk serbuk instan cascara Arabica.
