Lactoferrin

Lactoferrin is an iron-binding protein found naturally in numerous bodily secretions, including milk, tears, mucus, blood and saliva. It has an extensive range of biological properties and potential applications.

Properties

• very high affinity for iron
• bacteriostatic or bacterial agent
• antifungal (against Candida)
• antiparasitic
• immunomodulatory properties
• natural antioxidant
  

Lactoperoxidase

Lactoperoxidase is the most prominent enzyme found in milk.  In combination with its cofactors (peroxide and thiocyanate), it forms the lactoperoxidase system, which has potent antibacterial activity.  Lactoperoxidase is commercially available as a freeze-dried powder of defined activity.

Properties

• antibacterial (in combination with cofactors) against a wide range of pathogens, including Listeria and E.coli.
  

Glycomacropeptide

GMP is a large, glycosylated, heat-stable peptide cleaved from kappa-casein by the action of chymosin.  Many of its biological properties are associated with the presence of sialic acid residues.

Properties

• high level of glycosylation
• antibacterial
• antiviral adhesion
• anti-toxin
• modulator of digestive hormones
• low level of aromatic amino acids
• high levels of branched chain amino acids
  

Caseinate

Tatua produces an extensive range of caseinates, including calcium, sodium, magnesium, potassium and mixed caseinates.

Protein hydrolysates (whey, casein and vegetable)

By carefully controlling the enzymatic hydrolysis of proteins, Tatua produces a wide variety of protein hydrolysates and bioactive peptides for specialised nutritional purposes.

Properties

Compared to intact proteins, hydrolysates have:

• improved solubility
• enhanced heat and acid stability
• reduced viscosity, especially compared with casein

Studies have shown that nitrogen from small peptides (primarily di- and tri-peptides) is better absorbed than nitrogen from amino acids or whole proteins.

Whey protein concentrate

Tatua specialises in producing whey protein concentrates with enhanced gelling properties.

Anhydrous Milk Fat (AMF)

Tatua Anhydrous Milk Fat (AMF) is manufactured by the removal of moisture and non-fat solids from pure, fresh New Zealand cream. Tatua AMF is an ideal ingredient used to enhance mouthfeel, appearance, flavour and aroma in a wide range of food products.
