uuritava valgu asendamatute aminohapete ja võrdlusvalgu vastavate asendamatute aminohapete sisalduste jagamisel saadavatest suhtarvudest väikseim suhtarv
the lowest of the ratios between the quantity of each essential amino acid of the test protein and the quantity of each corresponding amino acid of the reference protein
Valgusisalduse alampiiri tõstetakse, kui keemiline indeks on käesolevate erinõuete lisas 1 toodud võrdlusvalgu 100%-st madalam. Valgu keemiline indeks peab võrduma vähemalt 80%-ga.
The chemical index of the proteins present shall be equal to at least 80 % of that of the reference protein (breast milk, as defined in Annex VI); nevertheless, for calculation purposes, the concentrations of methionine and cystine may be added together.
