BACKGROUND OF THE INVENTION
Cow milk allergy in infants caused by intolerance to certain proteins present in the cow milk is an important problem which can be commonly found. The number of infants suffering from such allergy has a tendency to constantly increase. The symptoms of cow milk allergy may vary, for example, atopic eczema, respiratory symptoms such as chronic cough or excessive sputum and gastrointestinal symtoms such as vomitting, diarrhea or stomachache, etc.
Nowadays, numerous formulas specialized for infants having cow milk protein intolerance have been invented and developed through several processes such as extensively hydrolyzed formulas or soy-based formulas, etc. However, such formulas still is allergenic to many infants. Therefore, the development of alternative formulas remains necessary to overcome the aforementioned problems. An example of such alternative formulas is amino acid- based formula. Hoever, although the commercially available amino acid-based formula can replace the common cow milk for infants having cow milk allergy, its affordability remains problematic to parents due to its high price.
