Conferences, Workshops and Seminars
International conference on Sustainable Foods – Achieving the Sustainable Development Goals (ICSF)
On 24 and 25 of July, in Bragança, the final public seminar of the PulpIng project. The event called 𝗜𝗖𝗦𝗙 aimed to disseminate knowledge regarding innovative processes and the development of sustainable food products. It brought together researchers, industry professionals, and consumers to share innovative ideas in this field and to present results from their work on this area with a special focus on the sustainable food innovation in the Mediterranean and the development of sustainable vegetable pulps formulations. During these two days 135 persons of seven different countries participated on the conference. In total, 6 oral communications and 56 Panel Communications was presented, joined by 3 Keynotes and 2 Plenary lectures.

Sustainable recovery of compounds with preserving capacity from pumpkin by-products
The sustainable recovery of compounds with preserving capacity from pumpkin by-products was investigated at CIMO-IPB, as expected in WP2. For that purpose, a primary study was carried out evaluating more than 100 samples of different pumpkin genotypes, including the seeds, fibers strands, and peels, in terms of their chemical composition and bioactivity. With these studies, it was possible to select the most promising extracts for food preservation. An extraction optimization study was, then, carried out comparing two different methodologies in order to reach the more effective extraction conditions.
Quality evaluation of raw materials
The identification of carotenoids in the pulp fruit of the Tunisian, Greek, and Egyptian pumpkin cultivars is the present emphasis of CRAPC research center after the characterization of carotenoids in the Algerian pumpkin varieties. The ongoing research is related with WP1 Task 1.4 (Quality evaluation of raw materials).
We initially extracted the carotenoids from the samples of the pumpkin cultivars before characterizing by NMR 400 MHz spectrometer in CDCl3 and then identified in accordance with the elution order at 450 nm, and quantified by HPLC/UV-vis system equipped with a C18 column and β-carotene as an external standard. Mobile phase A is composed of methanol/water plus 10 mM of ammonium acetate, and mobile phase B was gradient-mode-operated ethyl acetate/methyl butanol.
