Abstract

The objective of this research was to produce instant multigrain rice which has the potential as a functional food with high protein content, and as a source of dietary fiber. The design used in this study was a non-factorial Randomized Block Design (RBD), using 1 factor 5 treatments and 3 repetitions including F1 with concentrations (40% sorghum, 10% brown rice, 40% soybeans, 10% edamame) F2 (40% sorghum, 10% brown rice, 10% soybeans, 40% edamame) F3 (25% sorghum, 25% brown rice, 2 5% soybeans, 25% edamame) F4 (10% sorghum, 40% brown rice, 40% soybeans, 10% edamame) F5 (10% sorghum, 40% brown rice, 10% soybeans, 40% edamame). The analysis used in data processing is the ANOVA test followed by the Duncan test and analysis of the effectiveness index. The results showed that there was a significant effect on protein and dietary fiber content of several formulations. The resulting instant multigrain rice formulation has problems as a functional food, due to its high protein content and sufficient dietary fiber.

Abstract

Pisang merupakan buah lokal yang kaya akan gizi seperti vitamin C, protein, kalsium, vitamin A, dan zat besi, serta berpotensi dikembangkan menjadi produk pangan alternatif seperti beras pisang. Namun, kandungan enzim polifenol oksidase pada pisang dapat memicu reaksi pencoklatan (browning) saat proses pengeringan. Penelitian ini bertujuan untuk mengetahui pengaruh lama waktu blanching dan konsentrasi perendaman natrium metabisulfit terhadap karakteristik fisik dan kimia beras pisang Barlin yang dikeringkan menggunakan food dehydrator. Metode yang digunakan adalah Rancangan Acak Kelompok (RAK) dua faktor, yaitu tiga taraf lama blanching (0, 5, dan 10 menit) dan variasi konsentrasi natrium metabisulfit (0, 300 ppm). Hasil menunjukkan bahwa kedua perlakuan memberikan pengaruh nyata terhadap browning index dan kandungan karbohidrat. Semakin lama blanching, terjadi penurunan kandungan gizi akibat denaturasi, sedangkan perendaman natrium metabisulfit dapat menyebabkan pelarutan zat gizi ke dalam air. Perlakuan kombinasi perendaman natrium metabisulfit 300 ppm dan blanching 5 menit menunjukkan hasil paling optimal dalam menjaga tampilan warna cerah dengan browning indeks  70,50 ± 3,82, serta mempertahankan kadar karbohidrat yang relatif tinggi (67,27 ± 0,03%).
