PepsiCo posted this Technology Call

PepsiCo is seeking novel bottle and/or bottle closure sanitation methods that reduce or eliminate the use of chemicals and/or water in the sanitation process. It is very important to sanitize packaging containing beverages intended for human consumption. Failure to adequately sanitize bottles and bottle closures to remove bacteria, viruses, molds, yeasts, and spores may have serious consequences with respect to product quality and safety, potentially leading to negative customer reactions or even product recall. Peracetic acid (PAA) is a commonly employed and highly effective sanitizer, particularly when used in conjunction with hydrogen peroxide. However, PAA sanitation processes involve a significant amount of water throughout the process including dilution, water rinsing of packaging post-treatment and chemical disposal. Globally, trillions of gallons of beverages are bottled each year. While preserved carbonated soft drinks (CSDs) are the traditional leader in market share, other drinks such as bottled water, juices, non-preserved CSDs, and ready-to-drink teas and coffees are gaining in share. New inventions are needed to ensure that these drinks remain safe, while reducing unnecessary chemical and/or water consumption during production. Proposed solutions should achieve the following objectives: •Reduce or eliminate the amount of water used in bottle and/or bottle closure sanitation processes; and/or •Reduce or eliminate the use of chemicals in bottle and/or bottle closure sanitation processes.
