Abstract
The objective of this study was to elaborate flours of sprouts and sprouts by-product, and to evaluate the potential of sprouts by-products in the fresh pasta prodution. Firstly, alfafa sprouts flours and sprouts by-products flours were produced using conventional drying and freeze-drying. The results showed that the drying method promoted significant differences in moisture, lipids, proteins, total fibers, acidity, water solubility index, water activity and flours coloration. After evaluating results of yield and physical-chemical parameters, sprout by-product flour was selected for fresh pasta production with the following formulations: 5%, 10%, 20% and 30% of sprout by-product flour on wheat flour base (q.s. to 100%). Physical-chemical analysis and technological properties were also performed in all elaborated pastas. Considering the developed pastas, there was an increase in the ash content with the increase of the sprout by-product flour proportion added in the formulation. The technological properties analysis showed an increase in the cooking time and loss of soluble solids in the cooking water with the increase of the sprout by-product flour proportion; the 10% formulation was more adequate compared to the concentration range tested. Therefore, the sprouts by-product demonstrated to be a potential ingredient for paste products, aiming at nutritional and functional improvement.
