1. A method for producing a collagen peptide preparation, comprising:
a) expressing, from a coding nucleotide sequence, a collagen peptide having a molecular weight in a range from 8 to 100 kDa, and
b) enzymatically hydrolyzing the expressed collagen peptide under conditions to produce a collagen peptide preparation comprising hydrolyzed collagen peptides having an average molecular weight of 1 to 5 kDa, wherein
no more than 5.5 wt.-% of the hydrolyzed collagen peptides have a molecular weight less than 500 Da,
no more than 2.8 wt.-% of the hydrolyzed collagen peptides have a molecular weight between 7500 Da and 13500 Da, and
from 35 to 60 wt.-% of the hydrolyzed collagen peptides have a molecular weight between 1500 Da and 3500 Da.
