    Notes: Abstract The amino acid composition of food products frequently used in the diets of amino acid and protein disorders – including tryptophan – was estimated using ion-exchange column chromatography and high performance liquid chromatography. It includes fruits (different varieties of apples, pears, ananas, bananas, peach, strawberries, honey melon, water melon, kiwi, plums, grapes), vegetables (different varieties of potatoes, potato products, cauliflower, broccoli, cabbages, spinach, olives, lettuce, cucumber, peas, mushrooms) and commercially available or home-made food products (meat broth, fine gravy paste, ketchup, liquid seasoning, soja sauce, different varieties of Chinese noodles, sausages for phenylketonuria patients), and different new fiber concentrates.

    Notes: Abstract The protein quality of the diets of phenylketonuria (PKU) children of different ages (3 months, 10 months, 3 years, 8 years, 12 years, 16 years) with low or high phenylalanine (Phe) tolerance was assessed according to the recommendations of the FAO/WHO consultation group [13]. The amount of each essential amino acid (AA) per gram dietary protein was calculated and compared to the reference. The resultant amino acid score (AAS) indicated a limited to inadequate biological protein quality of the diets in 3-month-old infants (2.2 g protein/kg body weight/day) and 10-month-old infants (2.0 g protein/kg body weight/day) with a “high” Phe tolerance. In all other age groups the AAS was 〉 100%. However remarkable imbalances in the AA pattern were apparent. Beginning with the age of 3 years (1.7 g protein/kg body weight/day) the intake of the AA lysine and isoleucine was three or two times higher than recommended. At the age of 8 years (1.4 g protein/kg body weight/day) the intake of three AA (valine, isoleucine, lysine) was – related to the WHO recommendations – 217%, 229% and 291%. Similar results could be found in the age groups of 12 years (1.1 g protein/kg body weight/day) and 16 years (0.9 g protein/kg body weight/day), respectively. These calculations might help to reconsider the composition of the AA mixtures used in the dietetic treatment of PKU patients.
