Biscuits with Oleogels and Green Tea Extract Addition––Sensory Evaluation and Consumer Perception

Oleogels are a new trend in food technology aimed at enhancing the nutritional value of products that contain solid fats. Solid fats are rich in nutritionally unfavorable saturated fatty acids (FAs), but oleogels (lipid systems derived from oleogelator and oils) are in unsaturated FAs. The use of oils rich in oxidation-prone unsaturated FAs in pastry products requires the use of an antioxidant, such as green tea extract (GTE). However, new products with altered composition should also be acceptable to consumers. The purpose of this study was to carry out a sensory evaluation of short-dough biscuits obtained with 1% of GTE and high-oleic oleogels and to find what may influence consumers’ anticipated perception. Products with monoacylglycerols (MAG) and candelilla wax (CLX) oleogels and non-gelled high-oleic rapeseed oil (HORO) were found to have equal or better sensory quality compared to products with traditional baker’s (palm) fat (PF). In terms of sensory attributes, products with ethyl cellulose oleogels were the most distinct from the other biscuits. Their sensory qualities were significantly lower, with a more noticeable rancid odor and taste. Products with CLX and MAG oleogels were more preferred than those with PF, as consumers were more likely to purchase them based on sensory impressions. Information about the presence of GTE and HORO in the formulation was shown to affect the perception of the product. Similarly, the information about the low saturated fat content encouraged consumers to purchase such products. Based on this, it can be concluded that displaying this type of information can help educate consumers, support better decision-making, and promote the selection of more nutritious options.
