The data reported in this paper evidence that there is the need
for a better comprehension of pomegranate juice processing, and
major studies aimed to obtain a relationship among process and
health characteristic of PJ, in response to the increasing request of
pomegranate juice as a healthy food on the market. It was
demonstrated that the presence of peels during juice extraction,
allows obtaining PJ with higher polyphenols content and antioxidant
activity, therefore with higher nutritional properties. However,
it is necessary to control the percentage of the peels in order to
keep the bitterness under the threshold perceived as negative by
the consumers.
It also appears that enzymatic treatments, applied for the juice
clarification, increase the polyphenols content, even if obtained
juices presented a high turbidity and need a further clarification
step.
Further tests should be carried out on different pomegranate
cultivars and with different processing plants.
