A total of 4 carbonated soft drink (CSD) samples, from various locations in nine places of India were examined to determine their biological quality. Most samples were not in compliance with microbiological standards set by organizations like the World Health Organization (WHO). The prevailing bacterial isolates were Gluconobacter sp., Lactobacillus sp., and Leuconostoc sp. The prevailing fungal isolates were Penicillium expansum and the next isolate was Penicillium roqueforti. Many microorganisms are found in soft drinks as environmental or raw materials contaminants, but relatively can grow within the acidic and low oxygen environment. It is crucial for soft drink manufacturers to inspect raw materials before they are mixed with other ingredients. Concern with consumer health, safety and the environment will continue to have a positive impact on trend in the soft drink industry.
