Elementary mixtures are milk-replacement mixtures containing practically no traces of cow's milk protein, as its protein component is only free amino acids.
HTN (hypoantigenic) mixtures are preparations based on cow's milk in which the protein has been partially hydrolysed (broken down) so as to reduce the allergenic effect of the cow's milk.
Highly hydrolysed whey hydrolysates are a group of milk replacers (hypoallergenic) used for the treatment of cow's milk protein allergies in children.
Highly hydrolysed casein hydrolysates are a group of milk replacers (hypoallergenic) used for the treatment of cow's milk protein allergy in children.
