Abstract:
The aim of this study was to investigate the effect of tray drying on antioxidant and
antimicrobial activities of coffee pulp extract (CPE). Coffee pulp (CP) was dried at 70 ℃, 80 ℃
and 90 ℃ using tray dryer until the moisture content of sample reached 13 %. Then, the CP
was extracted with water to obtain CPE70, CPE80 and CPE90, respectively. Bioactive
compounds, antioxidant and antimicrobial activities against some pathogenic bacteria of the
CPEs were determined and compared to those of the freeze dried sample (CPEFD). It was
found that total phenolic content of the CPE90 (2.46 ± 0.02 gallic acid equivalent (GAE) /100 g
CPE db) was higher than that of the CPEFD (2.19 ± 0.04 GAE/ 100 g CPE db), CPE70 (1.78 ±
0.02 GAE/ 100 g CPE db) and CPE80 (1.73 ± 0.02 GAE/100 g CPE db), respectively. The
antioxidant activity of CPE90 (1,303.44 ± 56.09 g trolox equivalent (TE)/ 100 g CPE db) was
higher than that of the CPEFD (732.69 ± 30.28 g TE /100 g CPE db), CPE80 (688.24 ± 41.10 g
TE /100 g CPE db) and CPE70 (548.36 ± 31.93 g TE/ 100 g CPE db), respectively. At 200
mg/ml of CPE solution, it was found that antimicrobial activity of the CPE90 exhibited the
highest inhibitory effect against Staphylococcus aureus, followed by CPEFD, CPE80 and CPE70,
respectively.
