Application of yellow mustard gum‐fenugreek mixed gum in preparation of non‐dairy fat whipping cream

Abstract

SummaryYellow mustard gum (YMG) and fenugreek gum (FG) are both natural hydrocolloids derived from plant seeds. They showed synergistic effects of increased viscosity upon mixing thus expanding their applications. In this study, a synergistic YMG‐FG (7:3) blend of different total gum concentrations (0%, 0.05%, 0.1%, 0.15%, 0.2% and 0.25%, w/w) was used to develop a whipping cream formula with dairy fat replaced by palm kernel oil. Whipping creams of both liquid emulsion and whipped cream were characterised in terms of particle size, rheological properties, whippability and foam stability, texture and microstructure. The liquid emulsion before whipping showed a shear‐thinning behaviour regardless of the gum concentration. Upon whipping, the overrun of whipped cream decreased while the foam stability increased with increasing gum mixture content. The whipped cream with the addition of gum mixture retained the shape after storing overnight at 22 °C in comparison with two collapsed commercial samples. The whipped cream with 0.1% gum mixture exhibited optimal foam stability and textural properties among all the samples. Overall, the synergistic blend of YMG‐FG can be used as a natural stabiliser in formulating non‐dairy fat whipping cream products to improve foam stability and airy/fluffy texture.
