The experimental protocol used for yogurt supplementation and production are shown in Fig. 1. Skim milk powder mixed in distilled water (9.5% w/v) served as the base for supplementation
and will be refereed to as the “control”. In two series of experimental assays, 1–3% (w/v) of lentil flour or 1–3% of skim milk powder were added separately to the skim milk base (control).
