The results of the blanching tests did not allow for a good
adjustment of the proposed experimental design presenting low
determination coefficients (R2), which could be attributed to the
heterogeneity of the fresh fruits despite the initial selection of
the raw material used. Thus, neither the models nor the response
surfaces could be obtained to represent the influence of citric
and ascorbic acid concentrations on the color parameters under
study, and only the behavior of luminosity L* and total color
variation in relation to the fresh fruit (ΔE*) of the blanched and
non-blanched (control) star-fruits were evaluated
