1/31/2024 0 Comments Calculate pasteurization unitsThere has also been some progress with low temperature pasteurization methods using membrane processing technology. Milk based products– with 10% mf or higher, or added sugar (cream, chocolate milk, etc) Other time temperature combinations must be approved (e.g. Milk is deemed pasteurized if it tests negative for alkaline phosphatase.įrozen dairy dessert mix (ice cream or ice milk, egg nog): Or equivalent destruction of pathogens and the enzyme phosphatase as permitted by Ontario Provincial Government authorities. To ensure destruction of all pathogenic microorganisms, time and temperature combinations of the pasteurization process are highly regulated: Ontario Pasteurization Regulations An overview can be found on the next page. Thermal lethality determinations require the applications of microbiology to appropriate processing determinations. Minimum temperature and time requirements for milk pasteurization are based on thermal death time studies for the most heat resistant pathogen found in milk, Coxelliae burnettii. The extent of microorganism inactivation depends on the combination of temperature and holding time. Shelf life can be 7, 10, 14 or up to 16 days. Pasteurization can destroy some undesirable enzymes and many spoilage bacteria. Keeping Quality Aspect – to improve the keeping quality of milk and milk products.Public Health Aspect – to make milk and milk products safe for human consumption by destroying all bacteria that may be harmful to health (pathogens).Purpose There are two distinct purposes for the process of milk pasteurization: The heating of every particle of milk or milk product to a specific temperature for a specified period of time without allowing recontamination of that milk or milk product during the heat treatment process. The process was later applied to milk and remains the most important operation in the processing of milk. Therefore, a different sterilization schedule must be established for each product and each container.The process of pasteurization was named after Louis Pasteur who discovered that spoilage organisms could be inactivated in wine by applying heat at temperatures below its boiling point. Why are the sterilization schedules different ?ĭepending on the food, the recipes used and the type and volume of the can or jar, the heat penetration will be different. This is why the Thermotrack PC software integrates the automatic calculation of the sterilization value and the pasteurization value. The sterilization value is expressed as the equivalent of the time spent at 121.1☌ to obtain a destruction of the Clostridium botulinum spore. The higher the temperature and the longer the time is maintained, the higher the sterilization value. It is based on the destruction of the spores of Clostridium botulinum, the most resistant to heat. The sterilization value indicates the degree of efficiency of the heat treatment of a food. How to calculate the sterilization value ? The use of a waterproof temperature datalogger such as the iBee makes it possible to check at each production batch or periodically that the established time/temperature couple has been respected. In a HACCP approach, the control of the sterilization schedules established for your products is important to ensure that undesirable microorganisms have been destroyed. How do I check my sterilization schedule ? We carry out, if you wish, the calibration of your iBees, either with certificates linked to international standards or ISO 17025 certificates. It allows to use an unlimited number of iBees. It allows you to use a maximum of 5 iBees.Ĭontents of the pack : Thermotrack PC Pro software and a connection clamp for iBee. You can buy iBee by unit and complete with :Ĭontents of the pack : Thermotrack PC Cinco software and a connection clamp for iBee. Need : You only need one temperature datalogger for the product core control of your autoclave and you want to monitor your sterilizing and pasteurizing values on your PC.Ĭontents of the pack : 1 datalogger iBee 22T, a software Thermotrack PC solo as well as a connection clamp for reading.
