    Abstract

    A standardized whole cranberry extract (WCE) was used to stabilize a model sunflower-casein emulsion prototype for future formulation activities with a fresh cream cheese product. The WCE contained total organic acids (20% w/w) and polyphenols (5%), the latter consisting of total anthocyanins (10%, w/w) and proanthocyanidins (12% w/w). Antioxidant capacity of the WCE was determined by ORAC, (hydrophilic ORAC = 348.31 ± 33.45 µmol of Trolox equivalents/g; lipophilic ORAC = 11.02 ± 0.85 µmol of Trolox equivalents/g). WCE was effective at stabilizing the model emulsion at a level of 0.375% (w/w), yielding a final pH of 5.6. Generation of initial lipid peroxidation products, hexanal and pentanal was inhibited by 92.4% ± 3.9% and 66.6% ± 5.3% ( n = 3), respectively, when emulsions containing WCE were incubated at 50 °C for 90 h. This information was useful for formulating a fresh cream cheese product containing WCE to produce value-added potential and good self-life. The standardized WCE gave a final pH of 5.6 for the cheese premix and also significantly ( P < 0.05) lowered both the PV and CD after 28 and 21 days at 4 °C storage, respectively, compared to untreated control. We conclude that there are important functional role(s) for cranberry constituents when presented as a standardized ingredient for producing value-added, stable fresh dairy products.
