The term "unpasteurized" refers to a food or beverage that has not been treated with heat, specifically in order to kill bacteria and other microorganisms. This process is known as pasteurization, which was developed by Louis Pasteur in the 19th century as a way of preserving perishable items for longer periods of time.
Pasteurized products are heated to a specific temperature for a certain amount of time, killing off any harmful bacteria and extending their shelf life. However, some people believe that pasteurization can also destroy beneficial enzymes and nutrients in the food or beverage, leading them to seek out unpasteurized alternatives.
Unpasteurized products are typically found in natural or organic food stores, and may include items such as milk, cheese, yogurt, meat, honey, and wine. Consuming unpasteurized products can come with certain risks, including the possibility of contracting a foodborne illness from bacteria that has not been killed off during processing. For this reason, it is important for consumers to be aware of the potential dangers associated with consuming unpasteurized items and to make informed decisions about their dietary choices.
