The demand for use of natural fruit-based raw material for the manufacture of non-dairy desserts has significantly grown over the past decennium due to the increased number of people suffering from lactose intolerance, allergy to milk proteins and obesity. This study investigated the main physicochemical and rheological properties of non-dairy creams prepared from white and black seedless grape varieties, sunflower oil and stabilizers (inulin and xanthan gum) without added sugar. Generally, all cream samples showed a slight decrease in total polyphenols and antioxidant activity after processing, as compared to the reference raw material (fresh grapes). The Bingham, Casson and Herschel-Bulkley rheological models were used to predict the flow behavior of the developed creams. From the performance data analysis, it was found that only the Herschel- Bulkley model has been adequately fitted to the shear stress-shear rate data of all cream samples, resulting in the lower mean absolute error (MAE) and the strong correlations (R > 0.8) with a significant evidence (p [removed]80%) and lower oil content ([removed]100 Pa) and were more viscous than the rest of the samples. |
