Utilization of different oils and fats in cocoa hazelnut cream production

In this study, textural, rheological, particle size distribution (PSD), and sensory analyzes were performed to determine the possibility of using different oils or fats in production of cocoa hazelnut cream. The cream sample containing the margarine did not show oil separation as in the control samples. The closest accelerated fat separation values to the control samples were observed in cream samples containing margarine (6.87%) and sunflower seed oil (9.87%). The numerical D[4,3] values, represent the volume weighted mean particle diameter, obtained in samples with olive, sunflower seed, and palm super olein oils resembled results for control samples. Among the experimental samples, cream samples with hazelnut, margarine, and sunflower seed oils had the highest flavor and aroma scores. As fat or oil solidity increased, the oil separations and the flow behavior index decreased; however, the spreadability, stickiness, consistency index, apparent viscosity, the storage, and loss modulus and PSD parameters increased. Practical applications This study showed the effects of different fats and oils on technological characteristics of cocoa hazelnut cream. The results obtained will be beneficial in selecting the oils or fats in the production of cocoa hazelnut cream and determining the appropriate mixing ratios of them. Considering the cost and technological properties, anhydrous margarine, and sunflower seed oil could be suggested.
