Abstract
A method of microfiltering milk, milk serum, colostrum, or colostral serum which provides effective bioburden reduction without substantial loss of immunoglobulins.
Claims11
A method of preparing a whey product fortified with immunoglobulins comprising the steps of:
- (a) Collecting milk or milk serum from a mammal;
- (b) Centrifuging the milk or milk serum to remove fat;
- (c) Acidifying the remaining skim milk or milk serum to precipitate casein from the milk or milk serum, followed by removal of the casein by centrifugation;
- and
- (d) Microfiltering the supernatant milk or milk serum using a charged depth filter to reduce bioburden with immunoglobulin recovery of about 90% or greater.
A method of microfiltration of mammalian milk serum, colostrum, or colostral serum, comprising adjusting the pH of the milk serum, colostrum or colostral serum to about 4.0 to 6.5 and then microfiltering the milk serum, colostrum or colostral serum using a charged depth filter, wherein the bioburden of the milk serum, colostrum or colostral serum is reduced by at least about 4 log with immunoglobulin recovery of about 90%.
