Abstract

Nowadays, consumers are interested in low-fat ice creams. The potential of monoglyceride-based oleogel and oleofoam as fat replacers in ice cream production was explored. Ice cream with 50% oleogel possessed appropriate partial coalescence degree (PCD, 44.17%), complete network structure endowed ideal qualities and the generation of perceived creaminess. Increasing oleogel substitution level (100%) resulted in a higher PCD (60.20%), a decreased overrun (35.43%), and a decline in quality due to larger ice crystal formation. Fifty per cent oleofoam promoted higher viscosity and structural strength of ice cream mix, but excessive coalescence (72.83%) caused the formation of large fat aggregates in ice cream.
