      I hope someone can answer this question. On occassion a lactating mother will find that her pumped, frozen breastmilk has become "rancid". They report it to smell and taste sour. Babies refuse to drink it. Apparently the lipase in the milk breaks down the fat leading to this problem. All research instructs mothers to heat the milk prior to freezing to stop this process. Unfortunately, heating also destroys some cells in the milk. Is there any way to stop the process of the lipase other than heating?

      Why would you care about preserving cells?

      Yeah, there are, although i’ve no idea why you’d like not to destroy the cells. See, lipase, as you probably know, is an enzyme, so just take a biology book and look up for the other factor that affects the function of enzymes other than temperature, i.e. pH.
