Pomegranates fruits (P. granatum cv.Wonderful) of uniform size
and appearance were washed and manually peeled, by separating
and weighting the four components: arils (83.2 13.4 g/100 g),
endocarp, mesocarp (14.2 2.6 g/100 g) and epicarp (2.6 0.7 g/

from a second lot of fruits was further treated with a pectolytic
