Pengembangan Hybrid Tepung Ubi Jalar Kaya Antioksidan

Abstract: <p>Sweet potato is one type of tubers found in Indonesia. <em>Hybrid</em> of sweet potato flour is obtained from the modification of the processing by fermentation using lactic acid bacteria. The purpose of this study was to determine the nutritional and antioxidant content of various types of <em>hybrid</em> sweet potato flour. This research is an experimental laboratory with a true-experiment design. The experiment was arranged in a complete randomized block design (RCB) with th… Show more

“…This assumption is in accordance with the opinion of Aini et al (2010), which states that the decrease in mineral content occurs due to the leaching process due to substrate soaking during fermentation. Putri (2019) added that fermentation activities using Lactobacillus plantarum with a concentration of 5% caused the loss of some of the minerals contained in the raw materials due to the dissolution of minerals with fermentation bath water and waste before pressing.…”

“…Peningkatan produk dari ubi jalar dapat dilakukan menjadi produk setengah jadi melalui hybrid tepung ubi jalar yang selanjutnya dapat digunakan sebagai bahan substitusi tepung terigu pada produk donat, brownies, roti tawar, mie, biskuit, muffin dan lainnya. Hybrid tepung ubi jalar didapatkan dari modifikasi proses pengolahan dengan cara fermentasi yang memanfaatkan bakteri asam laktat (BAL) seperti Acetobacter xylinum, metode ini menjadikan aktivitas antiokasidan dari ubi jalar ungu meningkat, hal ini disebabkan karena karbohidrat difermentasi oleh BAL yang menghasilkan senyawa fenolik yang menyebabkan aktivitas antioksidan semakin bertambah karena fenol adalah termasuk dari antioksidan (Putri, 2019). Tata cara pembuatan tepung hybrid ubi jalar dapat dilihat pada gambar 2 dibawah ini :…”

“…Pada perlakuan A. xylinum memiliki kadar air 13,3% sedangkan perlakuan S. cerevisiae memiliki kadar air 9,67%. Hasil ini sejalan dengan Putri, (2019) fermentasi, maka suhu bahan pangan tersebut akan mengalami kenaikan sehingga air akan menguap, sehingga terjadi penurunan kadar air (Putri, 2019). Kadar abu pada perlakuan S. cerevisiae memiliki kadar abu paling tinggi yaitu 11,28%.…”

“…Hasil ini dikategorikan buruk kualitasnya, kualitas tepung akan semakin bagus jika kadar abunya semakin kecil. Kadar abu mempengaruhi warna dan tingkat kestabilan suatu bahan pangan (Putri, 2019). Pemberian starter S. cerevisiae mampu meningkatkan kadar abu di dalam tepung umbi bit, hasil ini tidak sejalan dengan Kustyawati et al, (2013).…”
