The effects of the inclusion of broccoli co‐products into crackers on the bioaccessibility as well as their overall physical and nutritional quality were evaluated. Crackers were formulated using a 12.5 or 15.0% flour substitution level. Broccoli‐containing crackers presented higher specific volume and spread ratio and lower weight and specific volume than control crackers (P < 0.05). Crackers containing broccoli co‐products showed an increased green hue and a higher colour intensity (P < 0.05). Incorporation of broccoli co‐products into crackers significantly increased the total phenolic content and antioxidant capacity (P < 0.05). A simulated gastrointestinal digestion suggested that the amount of phenolic and antioxidant compounds released during digestion might be higher than what could be expected from common water‐organic extracts. The incorporation of broccoli co‐products into baked crackers would not only reduce the amount of food discarded as waste but also promote health and open novel commercial opportunities to food processors.
