The Minitab ver16 software (Minitab Inc., State College, PA
16801-3008, USA) was used for analysis of variance (ANOVA),
and tests of significance at 95% confidence level. The total and bcarotene
retention values were expressed as the % of the carotenoid
content in each extrudate to that of the non-extrudate (Beerwah
Gold II (New)).
