Pasteurization reduces the number of vegetative forms. Does pasteurization kill all vegetative forms? Pasteurization kills harmful microbes in milk without affecting the taste or nutritional value (sterilization= all bacteria are destroyed). Pasteurization involves heating liquids at high temperatures for short amounts of time. Pasteurization is named for Louis Pasteur, who developed a method to kill microbes in 1864. It does not kill bacterial spores, so pasteurization does not truly sterilize products. Pasteurization is the process of applying low heat to kill pathogens and inactivate spoilage enzymes. Is boiling milk same as pasteurized?īoiling of milk certainly destroys all the pathogenic organisms and makes it safe for human consumption, but there is no need for heating the milk for such a higher temperature when the same objective is fulfilled by pasteurization process. Cool as quickly as possible after a little while they may be set into a pail of cold water. The steam surrounding the bottles, or jars of milk, heats them.
Pour water into the bottom of the pan below the rack of bottles and let boil twenty minutes after boiling begins. You might be interested: Often asked: How Much Calories Does A Glass Of Milk Have?

Pasteurizing milk is a simple concept: the recommendation is to heat milk to 161 degrees for 15 seconds (please note that this is far gentler than grocery store pasteurized milk, which is heated to nearly 300 degrees!) or to 145 degrees for 30 minutes.
