SUMMARY
Purple glutinous corn and white glutinous corn (Zea mays L.) are plants that are rich
in anthocyanins and contain γ-aminobutyric acid (GABA). This study aims to
determine the effects of fermentation using two types of lactic acid (Lactobacillus
casei and Lactobacillus brevis) and the effects of fermentation time (0, 24, 48 and
72 hours) on GABA content, antioxidant bioactivity, and chemical characteristics
(pH, polyphenols, protein, organic acids) from fermented purple glutinous corn milk
and white glutinous corn. The results showed that the type of lactic acid bacteria and
fermentation time had significantly different effects on pH, GABA, ABTS radical
inhibition, total polyphenols and total soluble protein of the two types of corn.
Fermentation of white glutinous corn using Lactobacillus brevis bacteria for 24
hours produced the highest GABA, namely 989.25 mg/mL. The highest antioxidant
was obtained from fermented purple glutinous corn using Lactobacillus brevis
bacteria for 24 hours, namely 95.59%. The longer the fermentation time, the pH of
the two types of corn decreased, while the total polyphenols and total dissolved
protein in both types of corn fluctuated. Qualitative test of purple glutinous corn and
white glutinous corn fermented by Lactobacillus casei and Lactobacillus brevis
showed the presence of GABA stains on the silica plate and the determination of
organic acids by HPLC purple glutinous corn fermented by Lactobacillus brevis
produced 7.63 mg/mL of lactic acid and acid acetate 2.49 mg/mL, while
Lactobacillus brevis fermented white glutinous corn produced lactic acid with the
highest levels of 10.98 mg/mL, acetic acid 1.59 mg/mL and butyric acid 1.12
mg/mL.
