BACKGROUND: Grape pomace (GP), a wine‐making by‐product rich in dietary fiber (DF) and total phenolic compounds (TPC), is a potential functional ingredient in the fortification of baked goods. RESULTS: In the present study, fortified breadsticks samples were obtained by replacing wheat flour with 0, 5 and 10 g 100 g−1 of powdered GP (GPP). The GPP inclusion affected the rheological properties of the doughs by increasing the water absorption and tenacity (P) at the same time as reducing the extensibility (L), with a significant increase in the P/L value and a decrease in the swelling index (G) value and deformation energy (W). Textural characteristics of breadsticks were influenced by the GPP addition, showing a reduction in hardness and fracturability as the amount of GPP increased in the recipe. The GPP fortified breadsticks exhibited decreased pH, volume and specific volume values compared to the control. The TPC and the antioxidant capacity increased in GPP fortified breadsticks, whereas the increased amount of DF allowed the products to benefit from the claim 'high fiber content' at the highest level of GPP inclusion. The sensory evaluation revealed that GPP addition increased wine odor, acidity, bitterness, astringency and hardness, and decreased the regularity of alveolation and friability. Finally, the GPP fortified products achieved good sensorial acceptability. CONCLUSION: GPP improved the nutritional values of fortified breadsticks and changed the rheology of dough and breadsticks' technological properties without affecting sensory acceptability. © 2021 The Authors.

BACKGROUND Pasta is a staple food that is consumed worldwide and is an excellent product for the addition of ingredients rich in bioactive compounds. The fortification of pasta with such compounds could represent a healthy choice for consumers. RESULTS: In this study, fresh pasta was formulated by replacing durum wheat semolina with 0, 5, 10, and 15 g 100 g−1 of dried Moringa oleifera leaf powder (MOLP), rich in fibers, minerals, and antioxidant compounds. Increasing levels of MOLP influenced the technological and nutritional properties of wheat‐based fresh pasta. Moringa oleifera reduced the optimum cooking time, the swelling index and firmness, while increasing the cooking loss and adhesiveness. From a nutritional viewpoint, the inclusion of MOLP enhanced the phenol content, the antioxidant activity, and the mineral content of fresh pasta. The products obtained had good sensorial acceptability and can make several nutritional claims due to MOLP richness minerals. CONCLUSIONS: The fortification of fresh pasta with MOLP could represent a valuable strategy to increase the nutritional value of the product, preserving pasta technological properties without affecting sensory acceptability. © 2020 Society of Chemical Industry [ABSTRACT FROM AUTHOR]
