Effect of antioxidant-enriched microcrystalline cellulose from almond residue on physicochemical and textural characteristics of mayonnaise

Abstract

The purpose of this study was to investigate whether antioxidant-enriched microcrystalline cellulose from almond residue (AE-MCC-AS) affects the physicochemical and textural characteristics of mayonnaise during 56 days of storage at 25 °C. The L * value of the mayonnaise decreased by increasing the AE-MCC-AS ratio; whereas the redness and yellowness values increased. The emulsion stability and viscosity increased by increasing the AE-MCC-AS ratio from 0.2% to 0.4%; however, they decreased with an increase in the AE-MCC-AS ratio from 0.4% to 0.6%. The largest oil droplets were observed in the micrographs of the control, 0.2% AE-MCC-AS-M and 0.6% AE-MCC-AS-M; while the smallest ones were observed in the micrographs of α-tocopherol-M, BHT-M and 0.4% AE-MCC-AS-M. During the storage period, the total MUFA and PUFA showed a declining trend in all treatments with a higher decrease in the control; while total SFA showed an upward trend with a higher increase in the control. In terms of textural characteristics, a significant declining trend (P < 0.01) was observed in firmness and consistency; whereas an upward trend was observed in cohesiveness during the storage in all treatments.
