Park et al. (2008a, 2008b) also found that all sensory
characteristics decreased with increasing GTP levels, but there was no significant difference in overall acceptability between Yukwa
samples without and with 1 g/100 g GTP. Park and Kim (2002)
found that green tea extract delayed rancidity in Yukwa,
providing compelling evidence that green tea extract is an effective
antioxidant for Yukwa. Furthermore, Sung et al. (2011) concluded
Yukwa combined with green tea reduced the effect of
hypocholesterolemia.
