Generally, untreated pomegranate juices present an excessive
turbidity, and a clarification is required during processing. Clarification
can be obtained by means of several methods: simple
filtration, precipitation of polyphenols and/or enzymation
processes.
In this paper, experimental pomegranate juices obtained from
different cleaning and enzymatic clarification steps were analysed
for their polyphenols and protein content and for other quality
parameters including pH, total soluble solids and acidity, in order to
correlate the technology to the composition of the juices, and find
the better processing conditions to increase the extraction of
polyphenol and other compounds with health beneficial effects
without exceeding the bitterness threshold accepted by consumers
