Romadhani, Triwulan (2019) Karakteristik Water Kefir Rambut Jagung Manis (Zea mays L. Saccharata) dengan Variasi Penambahan Konsentrasi Gula dan Kultur. Sarjana thesis, Universitas Brawijaya.
Abstract
Rambut jagung manis adalah salah satu limbah dari jagung yang kaya nutrisi dan senyawa bioaktif. Penelitian ini bertujuan untuk mengolah rambut jagung manis menjadi water kefir sehingga dapat meningkatkan manfaat fungsionalnya. Metode penelitian yang digunakan yaitu Rancangan Acak Kelompok (RAK) yang disusun secara faktorial dengan 2 faktor yaitu penambahan gula (8%,10%)(b/v) dan penambahan kultur (5%,7,5%,10%)(b/v). Perlakuan terbaik kefir air rambut jagung manis dengan penambahan gula 10% dan penambahan kultur 10%, kemudian dibandingkan dengan kefir air. Hasil analisa perbandingan menyatakan bahwa kefir air rambut jagung manis lebih baik daripada kefir air dengan karakteristik antara lain derajat keasaman (pH) 3,33 ± 0,12., total asam 1,33 ± 0,12 %; total bakteri asam laktat 4,13 x 106 ± 4,62 x 105 CFU/mL; total khamir 2,79 x 105 ± 9,11 x 104 CFU/mL, aktivitas antioksidan 65,24 ± 3,96 ppm dan kadar etanol <LOQ.
English Abstract
Sweet corn silk is one of the waste from corn which is rich in nutrients and bioactive compounds. This research is aimed to processing sweet corn silk becomes water kefir to increase the benefits of functional. Factorial randomized block design with 2 factors is used in this research. First factors was the concentration of variation of sugar addition (8%,10%) (b/v) and addition of culture (5%,7.5% and 10%)(b/v). The best treatment of water kefir sweet corn silk with 10% sugar and 10% culture additions, then compared to kefir water. The results of the analysis of water kefir sweet corn silk are better than water kefir with other characteristics the degree of acidity (pH) is 3.33 ± 0.12. total acid is 1.33 ± 0.12%; total lactic acid bacteria 4.13 x 106 ± 4.62 x 105 CFU / mL; total yeast 2.79 x 105 ± 9.11 x 104 CFU / mL, antioxidant activity 65.24 ± 3.96 ppm and ethanol content <LOQ.
