Because of glass’s higher thermal conductivity, it does this faster than plastic and we sense the glass as being colder. So while it’s not -actually- colder and wouldn’t keep the milk from spoiling for longer, it would affect our perception of how cold it is and therefore also the taste.
How do you store milk at home?

New research shows that increasing the temperature of milk by 10 degrees Celsius for less than a second eliminates more than 99 percent of the bacteria left behind after pasteurization.
How do you tell if milk is spoiled?
Spoiled milk has a distinct sour odor, which is due to lactic acid produced by bacteria. Other signs of spoilage include a slightly yellow color and lumpy texture (15). Signs that your milk has spoiled and may not be safe to drink include a sour smell and taste, change in color, and lumpy texture.
Why some milk is not refrigerated?
Milk is made shelf-stable (refrigeration not required for storage) by it at a higher temperature. Which is called ultra-high temperature pasteurization, or UHT pasteurization. … Secondly, the milk packaged in those bottles is in a sterile environment so that no bacteria or pathogens can contaminate the product.
Does boiling milk destroy vitamins?
Vitamins and proteins are denatured and destroyed when milk is boiled at temperatures above 100 degrees Celsius for over 15 minutes. Milk is a vital source for Vitamin D and Vitamin B 12, which help in calcium absorption. Both these vitamins are highly heat sensitive and boiling milk destroys both substantially.
What to do if milk curdles while boiling?
If the milk curdles when boiling, the first thing to do is to strain it and remove all the excess water. But before that make sure you boil it for some extra time. You can also wash this in water to remove any smell that irritates you and then squeeze out all the water.
