Google. The Late Middle Ages: Social and Political Breakdown (1300-1527) Why does organic milk last so much longer than regular milk? If you’ve ever shopped for milk, you’ve no doubt noticed what our questioner has: While regular milk expires within about a week or sooner, organic milk lasts much longer—as long as a month.
So what is it about organic milk that makes it stay fresh so long? Actually, it turns out that it has nothing to do with the milk being organic. All "organic" means is that the farm the milk comes from does not use antibiotics to fight infections in cows or hormones to stimulate more milk production. Organic milk lasts longer because producers use a different process to preserve it. According to the Northeast Organic Dairy Producers Alliance, the milk needs to stay fresh longer because organic products often have to travel farther to reach store shelves since it is not produced throughout the country.
Compare that to pasteurization, the standard preservation process. Retailers typically give pasteurized milk an expiration date of four to six days. Regular milk can undergo UHT, too. Food Preservatives - Nicholas J. Russell, Grahame Warwick Gould. What Are The Dangers Of Preservatives? Manufacturers use preservatives in many products that people consume and depend on for health.
Many companies also use them in cosmetics. The intent of preservative use is well-meaning, because they prevent botulism, mold and bacteria, which gives products a longer shelf life and protect people from illness. Unfortunately, many preservatives have dangerous side effects that cause cancers, hyperactivity, nervous system damage and other problems. It should be noted that many studies incorporate feeding massive amounts of a preservative to laboratory rats, so some preservatives consumed in small amounts may not be as dangerous as some studies suggest. Many soda manufacturers use sodium benzoate to prevent mold. Sodium nitrate, which is found in many packaged meats like hot dogs, sausages and bacon, is used as a curing agent. Food manufacturers use propyl gallate as a stabilizer in packaged meats, dried milk, candy, potato chips and baked goods.
