How is the milk you had for breakfast made safe to drink through technology?

Answer 1

Pasteurization involves heating milk to high temperatures to kill harmful bacteria that can cause illness. Milk is heated to a high temperature and then rapidly cooled. Pasteurization does not involve the use of any additives.
Apart from making milk safe to drink, pasteurization increases the length of time it can be kept before it spoils. The nutrient losses due to pasteurization are so small, they are considered insignificant.
Milk that has not been pasteurized is raw milk. Bacteria found in raw milk can be harmful.
Homogenization is a mechanical process that changes the size of the fat globules in milk. It keeps the fat from separating from the rest of the milk and gives milk a smooth creamy texture.
Homogenization does not change the nutrient value of the milk.
Milk that has been pasteurized by a special method involving ULTRA HIGH TEMPERATURES is called UHT milk. This process extends the shelf life of the milk without changing the nutrient value. UHT milk does not need refrigeration until after it is opened.

Answer 2

The milk I had for breakfast was raw milk, neither pasteurized nor homogenized.

It's safe because technology makes it reasonable to test the herd every two weeks, to make sure it's healthy.

It's safe because CIP (Clean-In-Place) technology ensures that the milking machine doesn't introduce bacteria to the milk.

It's safe because the cows are washed thoroughly before they are milked, using cleaners that were developed using modern surfactant technology.

It's safe because the milk was promptly chilled using modern technology, packaged in virgin plastic jugs, and refrigerated with modern refrigeration to a safe temperature.

Homogenization? There is *no* known health benefit to that. It's just a way to keep the cream from rising to the top, which makes it possible for large dairies to sell old milk in stores, instead of people having to buy fresh milk from farmers.

Pasteurization allows farmers with unsanitary practices to sell milk that doesn't kill everybody - but proper sanitation is a better way to do things. Pasteurizing milk removes all the beneficial bacteria in milk, so that the milk cannot defend itself from harmful bacteria; when pasteurized goes south, it goes very bad, very fast. On the other hand, I have a couple of gallons of milk that have sat unrefrigerated for a couple of months. It's turned to curds and whey, and when I get around to it, I'll finish turning it into cheese, but it doesn't stink.

Answer 3

The technology used to provide the safety of the milk you drink starts on the farm. The udder of the cow is sanitized before the milking machine is placed on the teats, After the milk is collected in the bulk tank it is rapidly cooled to prevent bacterial buildup in the milk. It is stored at a cool temperature until it is picked up in a refrigerated truck. When it reaches the processing plant it is pasteurized to eliminate bacterial contamination, placed in sterilized containers, and refrigerated to prevent bacterial buildup until purchased in the store. You then refrigerate it at home. This is just a brief summary of handling milk to make it safe. Technology also plays a role in the breeding and feeding of the livestock to promote the production of the milk.

Answer 4

Pasteurizing milk was began to extend the shelf life of milk. It now allows milk producers to produce milk in unsanitary conditions from diseased cows and make it "safe" to drink. Pasteurizing milk DOES harm the nutrients in the milk

"In recent years, there has been growing consumer interest in raw (unpasteurized) milk products, due to potential health benefits. Advocates point out that many beneficial components of milk are destroyed by pasteurization. Specifically, raw milk contains immunoglobulins and the enzymes lipase and phosphatase, which are inactivated by heat. Raw milk contains vitamin B6 of which up to 20% may be lost to heat treatment. Raw milk contains living bacteria which are in milk naturally but are killed by pasteurization, such as Lactobacillus acidophilus, the bacteria mainly responsible for the culturing of yogurt. Raw milk proponents point out that these "friendly" bacteria aid digestion and boost immunity." -wikipedia

Homogenization is being debated. Some studies say its bad and some say its not. Either way there is no benefit for the consumer to drink homogenized milk.

The best thing technology has done for milk is by refridgerating it from production, transportation and even in your house.

Answer 5

Besides the pasteurization already mentioned (heating up to almost boiling for s short time) the most important is the use of refrigeration from when the milk is collected until it is sold by the stores.

Answer 6

By largely avoiding technology. Other than pasteurization, my milk is produced naturally by hormone- and antibiotic-free grassfed cows. It is not only safer to drink, but tastes incredible and supports environmentally-friendly and sustainable agriculture on a local family farm. Which is good for all of us.

Answer 7

Actually, most of the above answers are incorrect. Industrialization developed most of the techniques mentioned above, such as refrigeration, homogenizatoin and pastuerization (bad spelling I know). Technology has allowed us to improve these techniques and keep better checks and balances in place which has led to greater productivity.

So in effect, technology has done nothing to keep your milk safer, it has only allowed those techniques used to be performed cheaper and faster.

Answer 8

its paturised :]

BUT if your one of those people who worrys their going to get ill from milk id really stop worrying.

for 15years ive lived on a dairy farm and probably everyday ive drank pure cows milk from our tank, and thats only been filtered through a fine filter and then chilled and ive always been really healthy and very rarely ill

sorry if you didnt want tht random info at the bottom :]

Answer 9

it's pasteurized , before that it is sucked out of the cows by machine that is sopsed to be very clean ie sterilized , but hand milking is the same.

Answer 10

Is pasteurized (look up Louis Pasteur) to remove harmful microbes.
