Abstract

Corn flour has undergone numerous modifications, however, the use of fermentation with Indigenous mixed cultures (molds and bacteria) followed by pregelatinization has not been extensively explored. The aim of the study was to assess the impact of fermentation with indigenous mixed cultures, specifically Aspergillus sp. (AS) and Lactobacillus fabifermentans (LF), on the physicochemical properties of modified corn flour, as well as its application in product quality. Corn flour was fermented using mixed cultures of AS and LF in a Complete Random Design (CRD) at five different ratios (AS: LF) of 1:0, 1:1, 1:2, 1:3, and 0:1. Each culture was incubated for 120 hours for AS and 48 hours for LF, then diluted by mixing 1 mL of the culture with 10 mL of sterile water. This diluted solution (according ratio) was aseptically added to a sterile corn flour dispersion at a ratio of 1:2 (w/v) and fermented under microaerophilic conditions for 48 hours. The fermented dispersions were dried and subsequently steamed (80°C) for 15 minutes at a 30% (w/v) ratio to prepare samples for analysis of amylose content, starch content, pasting, and rheological properties. The optimal AS: LF ratio determined through statistical analysis was 1:3, resulting in a final pH of 3.60 ± 0.10. The physicochemical properties of the corresponding steamed samples were as follows: amylose content (%), 17.45 ± 0.62; starch content (%), 68.94 ± 0.69; apparent consistency index (cP), 25,286 ± 512.9; and apparent power-law index, 0.32 ± 0.005, indicating pseudoplastic rheological behavior. The modified corn flour (AS: LF at 1:3) was then used in a 50% formulation for making bread and noodles. The resulting products showed potential for larger-scale development.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh waktu inkubasi terhadap aktivitas enzim selulase yang dihasilkan oleh kapang Aspergillus niger menggunakan substrat bubuk kulit tanduk biji kopi arabika serta karakterisasi pH dan suhu optimum enzim selulase yang dihasilkan. Jenis penelitian merupakan penelitian eksperimen model Rancangan Acak Lengkap (RAL). Penelitian ini dilakukan dengan terlebih dahulu menyiapkan bubuk kulit tanduk kopi arabika untuk dilakukan analisis awal, selanjutnya perhitungan kepadatan spora kapang A. niger dilakukan. Setelah itu, penentuan waktu inkubasi optimum, pH dan suhu optimum enzim selulase dikaji. Kapang A. niger ditumbuhkan pada media bubuk kulit tanduk biji kopi arabika dan diinkubasi pada rentan interval 0, 24, 48, 72, 96, 120, dan 144 jam untuk penentuan waktu inkubasi optimum, selanjutnya enzim selulase dikarakterisasi untuk menentukan pH dan suhu optimumnya. Karakterisasi enzim dilakukan pada pH 3, 4, 5, 6, dan 7 serta suhu 30oC, 40oC, 50oC dan 60oC. Hasil pengujian penentuan waktu inkubasi optimum menunjukkan bahwa enzim selulase dihasilkan oleh A. niger pada substrat bubuk kulit tanduk biji kopi arabika adalah pada waktu inkubasi 96 jam dengan nilai enzim 2181.93 U/ml, kemudian pH optimum diperoleh pada pH 4 dengan nilai 2053,04 U/ml, dan suhu optimum diperoleh pada suhu 50℃ dengan nilai 2614,88 U/ml.
