Original Title:
Ανάπτυξη και εφαρμογή μεθοδολογίας για την ανάκτηση προϊόντων υψηλής προστιθέμενης αξίας από βιομηχανικά απόβλητα ροδάκινου (Prunus persica)
Translated title:
Development and application of a methodology for the recovery of high added value products from peach industry waste
Summary:
Every year, in Greece, more than 300.000 tonnes of peach fruit (Prunus
persica), are used to produce juices and canned products. Consequently,
thousands tones of fruit waste are discarded, aggravating annually the
environment by a total of 3 million m3 of liquid and 23.000 tonnes of solid
waste. Peach solid and liquid wastes are rich in phytochemicals like phenolics
and carotenoids that have high economic added value. Within this project, a
method for the recovery of polyphenols has been developed and applied with eco
friendly approach. The methodology has been designed and improved in lab scale
and then was applied in pilot scale. The whole process was based on the
absorption resin technology and in pilot scale 220 kg peach pulp were extracted
and treated with resin XAD4 type in order to recover polyphenolic compounds.
Using a few simple steps of separations we have isolated and identified several
phenolic compounds that belong to flavonoids, phenolic acids, lactones and
triterpenes. All the isolated molecules were identified by Nuclear Magnetic
Resonance 1D & 2D NMR and Mass Spectroscopy. In addition, the peach kernel
(by-product) has been submitted successfully to Super Critical Fluid extraction
and we have obtained the kernel oil.
