dc.description.abstract | The aim of this research was to investigate the effect of the yeast viability, the role
of yeast on physico-chemical changing and the varieties of yeast on fermented
tauco in salt solution. This research had been performed using nonfactorial
completely randomized design (CRD) with fermentation time as a factor (i.e., 0, 1,
2, 3, 4, 5, 6, 7, 8 weeks) and three replicates. The result showed that the
fermentation time had significant effect on the yeast viability, pH, asetat acid and
reduction sugar. The result indicated that the highest total yeast was 14.4 x 107
CFU/ml on fourth week and the lowest was 0.1 x 107 CFU/ml on eighth week. The
results of physico-chemical changing indicated that the highest of reduction sugar
was 4.624 mg/g on seventh week and the lowest was 0.022 mg/g on fourth week.
The highest of pH was 5.5 on control and the lowest was 4.74 on eighth week. | en_US |
dc.description.abstract | Penelitian ini bertujuan untuk mengetahui pengaruh viabilitas khamir, peranan
khamir dalam perubahan fisiko-kimia dan keragaman khamir dalam proses
fermentasi tauco dalam larutan garam. Penelitian ini menggunakan rancangan
acak lengkap nonfaktorial dengan lama fermentasi (0, 1, 2, 3, 4, 5, 6, 7, 8
minggu) sebagai faktor perlakuan dengan tiga ulangan. Hasil penelitian
menunjukkan bahwa lama fermentasi berpengaruh nyata terhadap viabilitas
khamir, pH, kadar asam asetat dan gula reduksi. Hasil penelitian menunjukkan
bahwa jumlah koloni khamir tertinggi pada minggu ke-4 yaitu sebesar 14,4 x 107
CFU/ml dan jumlah koloni khamir terendah pada minggu ke-8 yaitu sebesar 0,1 x
107 CFU/ml. Hasil dari perubahan fisiko-kimia menunjukkan bahwa kadar gula
reduksi tertinggi pada minggu ke-7 yaitu sebesar 4,624 mg/g dan kadar gula
reduksi terendah pada minggu ke-4 yaitu sebesar 0,022 mg/g. pH tertinggi
terdapat pada kontrol (minggu ke-0) yaitu 5,5 dan pH terendah pada minggu ke-8
yaitu 4,74. | en_US |
