The aim of the research was to evaluate the effect of homogenization process conditions and formulation on physicochemical attributes of suspensions of pumpkin pulp ( Cucurbita moschata ) and hawthorn yam ( Dioscorea rotundata ) starch (OSAYS) modified with 2‐octenylsuccinic anhydride ( E / Z ) (OSA). A response surface methodology with a central composite experimental design was used to evaluate the effect of the independent variables: total solids contributed by the pumpkin pulp (TSPP) (3.5–3.8% w/w), OSAYS content (1–2% w/w) and homogenization time ( t hom ) (6–10 min), on the dependent variables: viscosity (μ), moisture ( X w ), pH, color coordinates ( L *, a *, b *), volume arithmetic mean diameter ( D [3,4] ), surface arithmetic mean diameter ( D [2,3] ), zeta potential (| ζ |), spectral stability index ( R ) and antioxidant capacity [2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) and 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS) methods]. Suspensions were prepared in a colloid mill equipped with a cooling jacket and operating at 466 × g . RESULTS The suspensions were physicochemically stable, conferred mainly by the synergy between the μ and the repulsive forces of the colloidal system (negative ζ ), even though the attractive forces were significant (relatively high D [2, 3] and D [3, 4] ). CONCLUSION Experimental optimization of the suspensions defined the independent variables: TSPP: 3.8%, OSAYS: 1.39%, t hom : 6 min, as: μ : 154.4 cP, X w : 94.3%, pH: 4.3, L *: 61.8, a *: 6.2, b *: 30.8, D [3,4] : 1321.9 μm, D [2,3] : 731.9 μm, R : 0.660, ABTS: 88.6 μ m Trolox and DPPH: 0.79 mg Trolox mL –1 . © 2025 Society of Chemical Industry. 10.1002/jsfa.70176 http://onlinelibrary.wiley.com/termsAndConditions#vor |
