The influence of Cistus incanus L. leaves on wheat pasta quality

Modern nutritional trends and looking for functional food and dedicated products for various consumers are a source of inspiration for scientists to develop new pro-health supplemented foods with high quality. Therefore, the present study aimed to determine the selected properties of common wheat pasta fortified with dried Cistus incanus in amount from 1 to 5% as a replacement of wheat flour. Pasta was made with a spaghetti shape and dried. Supplemented pasta was tested for total phenolics content, the total activity against DPPH, the ability to neutralize free radicals to ABTS and the antioxidant capacity reduction power, using various extraction procedures. Selected physicochemical properties of pasta were evaluated: cooking time, cooking weight, cooking loss, hardness and color profile of dry and cooked pasta in CIE-Lab scale, as well as the sensory properties of supplemented products. The addition of C. incanus to fortify wheat pasta increased total phenolics content and antioxidant activity with some significant differences according to the extraction procedure used. Methanolic extraction was more efficient than buffer extraction. Increased addition of dry Cistus herb caused higher cooking weight, cooking loss and increased hardness of cooked pasta. Studies have shown that C. incanus addition had a slight effect on color change with the largest decrease in brightness, especially for cooked products. Finally, it was found that advisable application of C. incanus addition to achieve nutritionally improved composition of pasta should not exceed 3% due to the proper sensory characteristics.
