At its Tartarica Treviso and Faenza plants, Caviro Extra produces natural tartaric acid – complying with the 100% bio-based carbon requirement – derived entirely from the sub-products of the wine-making industry, like wine marc and wine lees.
This emphasis on natural products represents a specific choice that matches the agricultural mission of the Caviro group – the largest wine industry in Italy – with 12,500 wine growers, 30 cooperative wineries and a production of 700,000 tons of grapes every year – and which is in sharp contrast with fossil-fuel derived synthetic tartaric acid.
The quality of the natural tartaric acid obtained has always been a source of pride for Caviro, being the result of an evolution originating in the 1920s, when the first production site was opened for what later became Tartarica Treviso, now incorporated into Caviro Extra.
In this way, Caviro controls the whole process, from the vine to the purity of a tartaric acid that has been chosen by the demanding producers of baby food, food supplements and functional beverages.
There are many sectors of industrial application for natural tartaric acid, whose importance and safety has been recognised by ancient studies and through centuries of widespread usage. In the modern context, the main sectors are:
FOOD. As an acidifying substance and natural preservative, as an emulsifier in industrial baking products and an ingredient in yeasts, biscuits, sweets, gelatine, marmalade, fizzy beverages and for sports products and baby food. It is obviously also employed in the oenological sector, as an adjuster of the natural acidity of wine.
PHARMACEUTICALS. It is used as an excipient and adjuvant of the active substances. It is used in syrups, capsules, effervescent powders, as well as in products that have a more restricted but highly specialised use, such as time-release band-aids, drugs to combat cardiac disease, etc.
CHEMICALS. It is used in cosmetics, for the production of cremes and powders, as well as for the production of surfactants, electronic devices, and used in printing, etc.
CONSTRUCTION. For the production of plaster and cements for renderings.
