<\/a><\/div>\n\nBeer Pasteurization – When and how it started?<\/span>\u00a0\u00a0<\/span><\/h2>\n<\/div>\n\nPasteurization process was discovered after the great French scientist Louis Pasteur<\/b> was able to extend the quality of beer by holding the beer at 55 –\u00a0<\/b><\/span>60o<\/sup>C\u00a0<\/span><\/b>(131 – 140<\/b><\/span>o<\/sup><\/span><\/b>F) <\/b>for a short time. Pasteurization and sterilization are confusing terms. In pasteurization, the beer is subject to sufficient heat to make the beer<\/span><\/a> free from microbial spoilage. However, low levels of some microorganisms might still survive the heating, without causing spoilage of the beer. In sterilization, high temperature is applied to destroy microorganisms. The targeted microorganism of pasteurization is <\/span>Saccharomyces cerevisiae<\/b><\/i>.<\/span><\/p>\n\nBeer is pasteurized by two methods-<\/span><\/h4>\n<\/div>\n\n\nTunnel Pasteurization<\/p>\n\n![](\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEhV2TEg41TT1VR7c6aH7NuxsHrR7U70VK0hCMnzV5grB25geROaZ8mHwX5M5yfbHkYmRiQvpTL9eZ5Jo7losqFgFKf42Xqa3W7TFRJwiJc4LoNbKC_L-uQwW1_wp6jjRrwNRqXoRgq1Gg\/s320\/tunnel+past..jpg\")

\nThis pasteurization is applied to bottles and cans of beer. In tunnel pasteurization, there is a tunnel of stainless steel. The liquid-filled bottles and cans are passed through the tunnel where hot water at temperature 60\u00a0– 65<\/b><\/span>o<\/sup><\/span><\/b>C<\/b>\u00a0is sprayed on the finished product. After the hot bath, the bottles and cans are sprayed with cold water to cool them down to <\/span>20 – 25<\/b>o<\/sup><\/span><\/b>C<\/b>. This pasteurization process is an ideal way to pasteurize beer. Tunnel pasteurization is very useful for commercial craft brewers for its advantages, such as –\u00a0<\/span><\/p>\n\n\n- Tunnel pasteurization offers an effective process in inhibiting pathogens and microorganisms.<\/span><\/li>\n
