Mi basah jagung memiliki prospek yang cukup cerah untuk dikembangkan dalam skala industri. Namun, karakteristik mi basah jagung terutama resistensi terhadap tarikan dan elongasinya masih rendah. Oleh sebab itu, diperlukan eksplorasi lebih lanjut untuk dapat meningkatkan elongasi mi jagung. Selain itu, diperlukan kajian terhadap kemungkinan pemanfaatan hasil samping dari tahap pembuatan tepung jagung sebagai bahan pangan.
Eksplorasi lebih lanjut juga diperlukan sebelum melakukan penggandaan skala dalam pembuatan mi basah jagung. Eksplorasi dapat dilakukan dengan tetap mempertahankan beberapa variabel proses yang penting yaitu derajat gelatinisasi adonan yang dipregelatinisasi (21,7%) dan kadar air adonan (38%).
