ABSTRACT In this work, hydroxypropyl methylcellulose (HPMC) was added into whipped cream for improving its textural and whipping properties. By determination of the particle size distribution, a single peak for the emulsion after homogenization and two distinguishable peaks for the emulsion after whipping for 5 min were observed. With the increase of HPMC level, the average particle size (d3,2) decreased for the emulsion after homogenization and increased for the emulsion after whipping for 5 min. Both whipping time and HPMC level showed positive effects on the partial coalescence of fat globules. The partial coalescence of whipped cream with 0.125% HPMC after whipping for 5 min reached 56.25%, significantly (P < 0.05) higher than that (4.77%) without whipping treatment. Surface protein concentration was measured to evaluate the change of protein content at the droplet interface. The results indicated that the increase of HPMC level could decrease the surface protein concentration slightly. The overrun of whipped cream slightly increased when the HPMC level increased in the range of 0.025–0.125%. Firmness, cohesiveness, consistency and viscosity of whipped cream were analysed in this work. HPMC showed a positive dose-dependent effect on all these textural properties.

    ABSTRACT: Small amounts of free (non-emulsified) fat in food emulsions can lead to an unacceptable appearance and product rejection. Most methods of analysis available for emulsions neglect this bulk scale heterogeneity and there is no generally accepted protocol to determine the amount of oiling-off. A new technique to determine free fat in emulsions was developed based on the principle that a lipid dye solution added to an oil-in-water emulsion will be diluted by the free fat but not by the emulsified fat present. The change in dye concentration (as measured from the decrease in absorbance) could then be used to calculate the amount of non-emulsified fat originally present. Oil Red O, a lipid soluble dye, diluted in corn oil was selected for this study. First it was shown the dye does not partition into typical aqueous food surfactant systems (2 wt% whey protein isolate, sodium caseinate, and polyoxyethylene sorbitan monolaurate) or emulsions (20 wt% corn oil) stabilized with the same surfactants. Corn oil spikes added to each of these emulsions, to represent different amounts of free fat, was quantitatively determined by this method. Finally the destabilization of the butter oil emulsion in ice cream mix during freezing was measured by dye dilution and compared to other methods (solvent extraction and turbidiometry).

    ABSTRACT: We studied four emulsions, stabilized by milk proteins, before and after application of whipping and freezing procedure. The emulsions were different in the whey protein/casein ratio and degree of heat-denaturation before mixing with the other ingredients. The supercooling needed for detection of crystalline fat was higher in emulsions than in bulk fat, and higher in emulsions containing casein or heat-denatured whey proteins than in emulsion containing non-pre-heated whey proteins. Furthermore, emulsions with high surface protein concentration and low crystalline fat content showed greater droplet aggregation under whipping and freezing. Our results indicated that differences in sensitivity to fat droplet aggregation was not caused by differences in resistance to protein displacement from the droplet surface in thawed whipped emulsions, but by low crystalline fat content prior to whipping and freezing. Data collected in this study were discussed in terms of effects of partial replacement of ‘native’ whey proteins by casein or heat-denatured whey proteins on partial coalescence of fat droplets in whipped-frozen emulsions.

    ABSTRACT: Understanding of the relationship between adsorbed milk protein layer characteristics and stability of butteroil emulsions may be applied to create emulsions with specific properties such as ice cream emulsions (quiescently stable, destabilizing under shear) formulated without chemical surfactant. Emulsions created from butteroil (25%) with skim milk powder (SMP) (0.2–0.7%), whey protein hydrolysate (WPH) (1.6–2.1%), whey protein isolate (WPI) (0.2–0.7%) and sodium caseinate (0.2–0.7%) were characterized for particle size distribution, protein surface concentration and relative stability when whipped. The SMP emulsions destabilized immediately after formation, possibly because of bridging flocculation. The levels of WPH required for quiescent stability prevented whipping-induced partial coalescence. At levels above 0.3% both WPI and sodium caseinate produced quiescently stable emulsions. Destabilization during whipping decreased as protein concentration increased. Whey protein isolate at a level of 0.3% was found to be the most suitable for producing an emulsion with the properties of an ice cream emulsion.
