Abstract

Purple corn is one of the corn varieties that is being developed by Indonesia as a form of food diversification. The purple color of corn is produced by the high presence of anthocyanins so it can provide health benefits such as antioxidant, anti-inflammatory, mutagenic, anti-cancer and anti-angiogenesis. To ensure that the bioactive components are not damaged, extraction is carried out in stages by applying the maceration method using a polar solvent with the correct ethanol content of 96%. Apart from using the appropriate solvent, the length of maceration time will determine the results of the extract obtained. This research aims to find out how long maceration affects the content of bioactive compounds found in purple corn. The research used a completely randomized design with one treatment, namely maceration times of 12, 24 and 48 hours. The tests carried out included color intensity, total phenol and anthocyanin content and antioxidant activity. The research findings explain that the length of maceration has a significant effect on color intensity, total phenols and antioxidant activity of purple corn extract. 2 hour maceration was the best treatment in extracting bioactive compounds, namely total phenols of 206.29 g/100 g, total anthocyanins of 0.19 g/100 g and antioxidant activity of 58.80%.

Abstract

Adanya pigmen karoten pada labu kuning dapat menjadikan tepung memiliki warna yang menarik. Akan tetapi, tingginya kandungan serat kasar dalam labu kuning dapat menyebabkan rendahnya nilai kecernaan, yang berdampak pada penyerapan zat gizi. Untuk mengatasi permasalahan tersebut perlu adanya teknologi fermentasi. Proses fermentasi dapat meningkatkan nilai nutrisi produk dengan penurunan senyawa antinutrisi, meningkatkan daya cerna dan ketersediaan makronutrisi. Tujuan dari penelitian ini adalah menganalisis karakteristik warna, karoten, serat kasar, kadar air, karbohidrat dan protein tepung labu kuning dengan variasi lama waktu fermentasi Saccharomyces cerevisiae; serta menentukan lama waktu fermentasi terbaik dalam pembuatan tepung labu kuning. Penelitian menggunakan metode rancangan acak kelompok satu faktor yaitu lama waktu fermentasi. Terdapat 6 perlakuan (0, 1, 2, 3, 4, dan 5 hari) dengan 4 kali pengulangan. Parameter yang dianalisis meliputi warna, karoten, serat kasar, kadar air, karbohidrat dan protein. Hasil penelitian menunjukkan bahwa lama waktu fermentasi meningkatkan kecerahan warna, warna kekuningan, kadar karoten dan karbohidrat; namun menurunkan warna kemerahan, serat kasar, kadar air dan protein tepung labu kuning. Lama waktu fermentasi terbaik dalam pembuatan tepung labu kuning adalah 3 hari. Tepung labu kuning terfermentasi 3 hari berpotensi sebagai tepung dengan warna menarik, tinggi akan kandungan karoten, protein dan karbohidrat, rendah serat dan kadar air sehingga memudahkan dalam proses penyerapan zat gizi dan memiliki umur simpan panjang.
