Utilização de farinha extraída de resíduos de uva na elaboração de biscoito tipo cookie

Abstract

The industrialization of grape is widely held, for the processing of different products, including wine, juice, jam, marmalade and raisins, along with their application in other areas, such as the manufacture of beauty products. However in its processing wastes are generated, which mostly end up being discarded without giving it a suitable target, wasting what could have one use and then be used to make products with added value. Solid waste from industrialized grape that may have economic interests are the pulp, seeds, stems, sludge, seeded, brochures, and fun. Many of these wastes have a variety of biologically active species and are rich in phenolic compounds. In this context, evaluating the importâmcia these aspects mentioned above, this study aimed to prepare a meal from bagasse generated in the production of grape juice, to develop a meal of biscuits and assess the bioactive compounds present in the residue, flour and biscuits produced. The study was conducted by means of physical-chemical properties of flour, which were pH, acidity, moisture and ash to characterize them. From the formulations are prepared flour cookies with substitutions of 5, 10 and 15% of wheat flour for cake flour. Sensory analysis was subsequently performed with 80 judges being applied a test of consumer acceptance and intent in order to determine the most acceptable sample for later realization of bioactive compounds. The cookie with the addition of 10% flour grape marc was what had the most accepted being evaluated total polyphenols, total anthocyanins and antioxidant capacity of the same. The flour was within the limits stipulated by the legislation and the physico-chemical variables analyzed. Regarding the analysis of bioactive compounds bagasse, flour and cookie showed the compounds studied, being found in greater quantities in the bagasse. This study allowed the development of grape pomace flour and cookie, and characterization of bioactive compounds from grape pomace generated in the production of grape juice and byproducts, enabling the correct disposal of waste, its use , as well as providing the company products with potentially beneficial to health.
