Investigating the complete replacement of conventional fat with oleogel on the structural behavior of five different pastry products

Saturated and trans fat intake have been linked to an increased risk of developing diseases such as cardiovascular and coronary heart disease, obesity, and myocardial infarction. As a result of the actions and regulations proposed to reduce and eliminate the content of saturated and trans fats, it is necessary to develop and implement new structuring technologies, such as oleogelation. Oleogelation is a promising strategy for structuring liquid oil, that allows the incorporation of vegetable oils rich in unsaturated fatty acids into food matrix and which can provide the functionality of solid fats and improved nutritional characteristics. The partial or total replacement of conventional fats with oleogels in pastry products is of great interest due to their larger consumption. In this research paper, the puff (jam-filled puff pastry) and tender pastries (bow tie cookies, cheese crackers, apple pie, and cookies) have been reformulated by totally replacing of conventional fats with oleogel and the structural behavior in the dynamics of the technological process was evaluated. The textural properties of oleogel were comparable to those of some conventional fats, but frequency sweep measurements showed that the oleogel formulated with refined sunflower oil and carnauba wax (10
