Figure 4

Digestion Model. The model has two digestion steps. In the first, the target protein is digested into intermediate fragments with the same length as FgLen. In the second, these intermediate fragments are further digested and the respective ALFFs are calculated. The longest ALFF is selected, shown as the dotted line. FgLen is changed from 50 to 80, the longest ALFF at different FgLen is collected into a set, and the average of the set is used to evaluate the resistance of the protein to gastric fluid digestion.
