Pasteurization: What It Means and How It Changes Food
Milk offers a place where numerous pathogens grow and increase in numbers, including those that may cause tuberculosis, scarlet fever, E. coli, and more.
Before pasteurization, raw milk has been many milk-related diseases and deaths; only after the pasteurization process was introduced, milk-related diseases dropped drastically.

Refrigeration slows down the process of nutrition degradation. The nutritional loss varies from product to product.
Spinach loses 100% of its vitamin C content in seven days at room temperature and 75% if refrigerated. Carrots lose 27% of their vitamin C content when stored at room temperature for a week.
However, when vegetables are frozen, including spinach, they lose significantly less vitamin C, because freezing pauses the process of oxidization.
As soon as produce is harvested, it's a nutritional race against time.
Frozen produce has one problem: before it's frozen, it's blanched - heating food up for a few minutes at high temperatures to inactivate enzymes that degrade texture and color. Blanching also reduces nutrient content.

Most foods spoil because of the growth of microbes. Preserving food is an attempt to limit microbial growth. Food can be preserved by drying, salting, chilling, or storing in air-tight containers.
Preservatives are used in foods to extend their shelf lives. One of McDonald's Big Mac in Iceland is an example of a long-lasting processed food. It has been on display since 2009, in a glass box. Preservatives that has been discontinued by McDonald's are:
