Once again, glass packaging in food storage confirms its qualities and is the preferred container.
This emerged from research conducted by the Department of Science and Innovation of the University of Eastern Piedmont, which studied the conservation in containers of different materials on the chemical-physical and food characteristics of tomato puree.
Glass, tin and multilayer containers containing tomato puree were compared.
Then both organic and inorganic species were analyzed, with particular attention to vitamins (B1, B2, B5, B6, folic acid (B9) and ascorbic (C), carotene, antioxidant species (of which the puree is particularly rich) and other interesting species for their health properties (quercetin, epicatechin) and also the inorganic contaminants that could be released from the containers.
Research has shown how storage in glass keeps all the good things (vitamins and nutrients) that are in the past unaltered.
Tinned samples, in general, show a higher content of tin, iron, possibly as a result of migration from the container, as well as a number of volatile compounds.
While the samples stored in multilayer containers show, on the other hand, a much lower content of vitamins, especially the very important ones of group B, and a higher content of a group of volatile compounds.
Packaging is increasingly fundamental because it could unintentionally be a means of contamination, producers must choose the safest one.
It is only a glass packaging that guarantees the total integrity of the product while preserving all its quality. So when it comes to food safety the chosen container is the one made of glass.
We choose our tomato purees packed in glass jars, to taste one of our “made in Italy” excellences.
