Concentration of foodborne viruses eluted from fresh and frozen produce: Applicability of ultrafiltration
The objective of this study was to optimize an ultrafiltration (UF) concentration method for HAV and HuNoVs present on various fresh and frozen produce. The detection range of the optimized method and its applicability to different food matrices was compared to the reference method ISO 15216-1:2017. Strawberry, raspberry, blackberry, lettuce, and green onion (25 g) were contaminated with HAV, HuNoV GI.7 and HuNoV GII.4 and then recovered therefrom by elution. A commercial benchtop UF device was used for the concentration step. Viral RNA was extracted and detected by RT-qPCR. From fresh strawberries, recovery of HAV loaded ...

Highly flexible carbon nitride-polyethylene glycol-cellulose acetate film with photocatalytic antibacterial activity for fruit preservation
Int J Biol Macromol. 2024 Mar 26:131161. doi: 10.1016/j.ijbiomac.2024.131161. Online ahead of print.ABSTRACTCellulose acetate film, as a biodegradable and biomass-derived material, has great potential applications in food packaging. However, the poor mechanical and antibacterial properties limit its applications. Herein, a highly flexible carbon nitride-polyethylene glycol-cellulose acetate (CN-PEG-CA) film was successfully prepared by combining graphitic carbon nitride (g-C3N4) photocatalyst with cellulose acetate (CA). The g-C3N4 enables the film with antibacterial activity, as a green photocatalyst. PEG softens the rigi...

The Mediterranean diet: a historical perspective
Aging Clin Exp Res. 2024 Mar 23;36(1):78. doi: 10.1007/s40520-023-02686-3.ABSTRACTThe Mediterranean diet, which was born in the Mediterranean basin, was initially quite poor and simple, essentially based on the products that grew almost spontaneously along the shores of the Mediterranean, i.e., olives, grapes, and wheat, which were long cultivated in the Mediterranean region. The invasions of the Roman Empire by barbarian populations, between 400 and 800 AD, made the diet enriched with products from wild uncultivated areas, meat from game and pigs, and vegetables. With the arrival of the Arabs in southern Italy in the nint...

Pectin From Fruit Peel Waste: A Sustainable Source for Production of Active Packaging Films
Composite film prepared using PVA, pectin form passion and lime peel had excellent mechanical, optical, thermal and bioactive properties. This film was used to pack strawberries and plums during chilled storage. Active film could significantly increase the shelf life of both the fruits. ABSTRACTPectin from lemon and passion fruit peels was studied for its potential to serve as a source of biopolymer for preparation of active film. To develop a packaging film appropriate for fruits, different combinations of polyvinyl alcohol (PVA), pectin from lemon and passion fruit peel and rosemary essential oil (REO) were evaluated. Ex...
