The new pasteurization method of milk has been put into practical use, and it is said that the shelf life of milk has been increased by four times compared to the existing pasteurization method. It is said that the idea of a new technology put into practice this time was developed in the former Soviet Union during the Cold War.
Puerto Rican dairy company Tres Monjitas has teamed up with Millisecond Technologies, which develops the next generation of pasteurization technology, to develop a new pasteurization method that quadruples the shelf life of milk.
The pasteurization method jointly developed by the two companies is to pasteurize the milk while applying pressure. It is said that pressure is applied to liquid milk to push bacteria and other microorganisms out of the droplets, making pasteurization more efficient. This technology is based on a study from Purdue University in the United States published in 2016. Purdue University research is based on ideas developed by the former Soviet Union during the Cold War. It is said that the Soviet research team, whose research was suspended due to difficulties in the Cold War period, came to the United States for a new research field, and they continued to conduct research in collaboration with Purdue University to lead the development of this technology.
According to the paper, this pasteurization technique effectively kills the bacteria that cause degradation in milk. Increased milk shelf life to 57 days. The shelf life of milk using the existing pasteurization technology is 14 days, but the milk sterilized with the new technology lasts four times longer. Purdue University’s research team revealed that there was no difference in taste between milk using a new sterilization technology and ordinary low-temperature fattening milk by conducting a taste examination of milk through a blind test.
Tres Monhitas is planning to release milk using the new technology in October. The expiration date for this milk is set to be 40 days. The company plans to start selling milk in the U.S. Virgin Islands and expand sales throughout the Dominican Republic. Related information can be found here .
