Various factors can affect the taste and quality of the beverages. These factors include temperature, nutrients in water which may lead to growth of microorganisms such as E. coli. and salmonella, pollutants in the water, and food ingredients like certain additives and preservatives.
Therefore, a stringent testing approach for water and ingredients is the first step towards beverage quality control. Moreover, beverages are subject to scrutiny by the global regulatory agencies. Application of quality control techniques through testing, inspection and auditing can help beverage manufacturing units comply with regulations and improve their product's acceptability among consumers.
