Bacillus coagulans was added as probiotics in instant coffee with microground roasted coffee which is recently rising premium coffee and the instant coffee (ProBio coffee) was compared with 3 commercial instant coffees with microground roasted coffee in quality characteristics to understand the competitiveness of ProBio coffee. In sensory evaluation, ProBio coffee had inferior aroma intensity and overall acceptance compared with control group (brewed coffee) (p<0.05) but it had equal quality or more compared with 3 commercials. Total polyphenol content, chlorogenic acid content, DPPH free radical scavenging activity and caffeine content were 110.72±1.99 ㎎/g, 2,700±20 ㎎/g, 146.22±3.62 TEAC ㎎/g, 28.1±3.2 ppm respectively. In general quality characteristics, water content, solubility, particle size and particle strength of ProBio coffee were similar to general instant coffee but had darker color than it. In safety assessment, acrylamide content was 502±10 ppb, and residual pesticides and ochratoxin A were not detected. Over 70% of B. coagulans were maintained in 4 months of storage and 16 months of shelf life was predicted in ProBio coffee by Q10 model. Therefore, ProBio coffee was confirmed to have a sufficient product competiveness compared with 3 commercials.
