In the experimental study, fresh spaghetti showed chroma a* values between 2.90 and 5.36 (Fig. 2A). The lower values of chroma a* occurred inside the area between points 3, c, d and e in formulations of fresh spaghetti with 75e80 g 100 g1 (highest concentrations) DPP, 9e14 g 100 g1 EPP and 10e13 g 100 g1 AF. The highest value for the chroma a* was recorded in the area between points 5, a and b in spaghetti with 68e69 g 100 g1 DPP, 7 and 8 g 100 g1 EPP and 24e25 g 100 g1 AF. Because the amount of AF was increased in the formulations the red color value of the spaghetti increased because dry AF had a redder.
