At the end of storage, the lowest relative losses in FRAP values, in the range 20-34%, were noticed in samples with 1% pectin and the highest 31-411%) in jam samples with 0.3% pectin decreases.
Moreover, a similar distribution has been noticed observing samples treated with NANOMATCH1 product, independently from the site exposure.
Moreover, we noticed that samples of PFo collected from Hong Kong were all large whole leaves and they were sold in a bundle.
After 6 months of storage, the best retention of TMA was noticed in samples with LMAP and the lowest in jams with HMP.
Moreover, when high level of protective culture was used a significant reduction of L. monocytogenes counts were noticed in samples packaged in 60% of CO2 along the storage period, although sensory properties were also affected.
Based on the differences of polarity between the three solvents used (M, W and AA), higher EF values have been noticed for samples 1, 3 and 4, richer in polar molecules, such as phenolic compounds.
Due to observation of region 1 (specific to terpenoids), it has been noticed that samples 6, 5 and 4 possess bands located at higher wavenumbers in AA, similarly to the results of UV spectra.
It was noticed that samples prepared using FeCl2 solutions with concentrations 0.025 M 0.075 M, 0.100 M and 0.125 M, have the same size particles, about 11 nm, and same size of γ-Fe2O3 grains, about 8 nm.
At the end of storage, the lowest values of PC, in the range 21-29%, were noticed in samples with LMAP and the highest, in the range 31-45%, for jams with HMP.
