Protein Fractions

Whey Protein contains many bioactive components including immunoglobulins, lactoferrin, and lactoperoxidase, and also contains a range of growth factors. (Chmiel, 1998; Perraudin and Reiter, 1998; Regester et al., 1998; Smithers et al., 1998; Francis et al., 1995).

There are many proposed and possible biological actions of these minor components, and evidence is largely based on in vitro observations and animal studies. Ongoing research is required to substantiate many of the physiological benefits in man.

ß-Lactoglobulin

ß-Lactoglobulin is the predominant whey protein in NZMP WPI and is the richest source of the sulphur amino acids. ß-Lactoglobulin has immune enhancing properties, possibly via its cysteine content as a precursor for glutathione, or its retinol binding and transport properties. (Regester et al., 1997).

a-Lactalbumin

a-Lactalbumin has a high dietary essential amino acid content and is the richest natural source of Tryptophan. a-Lactalbumin may also have anti-tumour activity. (Hakansson et al., 1995)

BSA (Bovine Serum Albumin

BSA is high in sulphur amino acids and glutamylcycsteine, both of which are precursors for glutathione. (Bounous et al., 1993). It has been shown to have immune enhancing and anti-mutagenic actions. (Bossalaers et al., 1994).

Immunoglobulins

Immunoglobulins in whey have been shown to enhance immune defenses via passive immunity in the gut. Immunoglobulins help reduce the duration and severity of diarrhea caused by pathogens in infants, children and immune-compromised individuals (Mitra et al., 1995; Rump et al., 1992; Ungar et al., 1990; Tzipori et al., 1987)

Lactoferrin

Lactoferrin has natural antioxidant, antibacterial/antiviral and immune-stimulating properties. Its ability to bind, transport and deliver iron in the intestine is thought to be one of the mechanisms by which lactoferrin helps to maintain a balanced level of intestinal microflora. (Kuwata et al., 1998; Dionysius and Milne, 1997; Miehlke et al., 1996; Harmsen et al., 1995; Applemelk et al., 1994; Yamauchi et al., 1993). However, in addition of bovine lactoferrin to infant formula has not yet been proven to affect the iron status of infants. (Chierici et al., 1992;)

Lactoperoxidase

Lactoperoxidase is an enzyme which catalyses the oxidation of thiocyanate ions, together with hydrogen peroxide, to produce reactive intermediates with anti-microbial (Bjorck et al., 1975; Steele and Morricsons, 1969) and antioxidant properties (Perraudin and Reiter, 1998).

GMP (Glycomacropeptides)

GMP is a fraction from ?-casein that appears in whey after rennin action. NZMP MF WPI contains high levels of GMP (16% w/w). GMP contains high levels of BCAA and low phenylalanine. Research has indicated that GMP may regulate appetite, bind microbial toxins, exert antibacterial properties, enhance our immune system, possess anti-cell proliferation activity, be anti-thrombotic and reduce dental caries. (Monnai and Otani 1997; Abd-E-Salam et al., 1996; Doska et al., 1992; Maubois et al., 1991)
