Some enzymes are inactivated during pasteurization, but they are not important for human health. Any other nutrients reduced in pasteurized milk are frequently found in other foods. The importance of pasteurization Milk is as natural as it gets. The power of pasteurization Pasteurization is the process of heating milk to destroy potentially harmful pathogens.
Illness from raw milk Recent trends in selling raw milk over the past few years have led to more than 80 outbreaks of food borne illnesses , including listeria, salmonella and E. This is especially important for soft and semi-soft cheeses like Brie, Camembert and blue-veined cheeses. If you are not sure if a cheese is pasteurized, look on the label or ask at the grocery store or restaurant.
Honey is pasteurized to help it last longer. Pasteurization does not make honey safer to eat. However, it is recommended that children under one year of age avoid honey whether it is pasteurized or not. This is because of the possible risk of infant botulism. Pregnant women who are healthy do not need to avoid honey. Cider and fruit juices are not required by law to be pasteurized. However, these drinks may become contaminated during handling, processing and transportation. Pasteurization helps to get rid of bacteria, viruses or parasites that may be in cider and fruit juices if they have not been handled properly.
It is best to buy pasteurized juices and ciders. However, if you buy unpasteurized cider or fruit juice, keep it refrigerated and look at the best before date shown on the package before drinking it.
It is not recommended that children, pregnant women, older adults or people with a weakend immune system drink unpasteurized juice and cider. If you would like to use raw or lightly cooked eggs in a recipe like eggnog, mayonnaise, salad dressing or homemade ice cream, use a pasteurized egg product instead of raw eggs. Pasteurization kills harmful Salmonella bacteria. Pregnant women, children, older adults and people with a weakened immune system should avoid eating foods with raw or lightly cooked eggs that have not been pasteurized.
Pasteurization helps to keep food safe for us to eat. Know the facts before consuming any food or drink that is unpasteurized. In most cases, the pasteurization process involves heat-treating products, usually with steam or immersion in hot water. The product may be pasteurized inside or separate from its packaging, but the idea is the heat will kill off any unwanted pathogens.
The heating process is very carefully controlled. It should be hot enough to get the job done, but not so hot that it alters the product in a detrimental way.
As such, very specific target temperatures are used in the process. Once a product reaches its target temperature, that temperature is held for a set time. Again, this is very carefully regulated to maintain the integrity of the product.
Once the time period is over, the temperature is lowered back to the desired level for the market. Pasteurizers come in various configurations, including steam box pasteurizers and tunnel pasteurizers. With a steam box pasteurizer , a case, pallet, or vat of the product is placed inside a chamber, which is raised to the desired temperature with steam.
This method is great for large batches of product at once. A tunnel pasteurization system runs the product through a series of chambers in which its temperature is gradually brought up with hotter and hotter jets of water. Tunnel pasteurization systems are perfect for fragile packaging and as part of continuous production lines. At Smart Machine Technologies, we design pasteurization systems that can handle solid and semi-solid products in a reliable, efficient manner. Let us help you improve your pasteurization process.
