Effects of Pitaya Peel Supplementation on Nutritional Quality, Overall Sensory Acceptance, In Vitro Glycemic Index, and Antioxidant Release from Fiber-Enriched Cookies

Figure 3

Antioxidant release from cookies supplemented with different ratios of pitaya peel powder in the in vitro digestion; the values with different lowercase letters (a–e) above the columns which have with the same pattern fill are significantly different ( < 0.05).
