The industrial by-product of blueberry juice, a source of fibre with antioxidant capacity was used to develop cookies. Once dried and ground the blueberries by-product, its composition and functional properties were analyzed and used to develop fibre enriched cookies. A central composite design was used to optimize the cookie formulation maximizing antioxidant and total polyphenol content varying fibre content (3-9 g/100 g), baking temperature (160-180 °C) and dough thickness (0.5-1.0 cm). Antioxidant capacity and total polyphenol content showed both a similar behaviour, increasing when fibre content increases. The increasing of dough thickness and baking temperature decreases the antioxidant capacity and total polyphenol content. Cookie with 9% fibre, 180 °C baking temperature and 0.50 cm dough thickness and cookie with 9% of fibre, 170°C baking temperature and 0.75 cm dough thickness showed maximum antioxidant capacity and polyphenol content with no significant differences between them; both cookies can be labelled using a fibre claim.
Practical Application: Processing fruit into juice generates waste with its corresponding environmental impact. Blueberry by-product could be considered a bioactive-rich ingredient with a prolonged shelf-life, source of dietary fibre and phenols. The growing interest of consumers for eating healthy products has led the industry to improve the nutritional composition of food. This improvement may be achieved by adding functional ingredients, like blueberry pomace, to widely consumed food products.
