Why gases are used in the fruit and vegetable and preserves supply chain
For fresh fruit and vegetables, fourth- and fifth-range products, preserves and sauces, oxygen management is the critical variable: it determines the rate of oxidation, bacterial growth and the loss of organoleptic properties.
The use of certified food-grade gases makes it possible to extend shelf life, preserve colors and aromas and reduce waste, from rapid cooling during production to final packaging
1
Extended shelf life with MAP without chemical preservatives
2
Instant cooling of sauces and gravies with Kryos 2.0
3
IQF freezing for berries and small-sized products

Certified food-grade gases and technological solutions for the entire supply chain: from rapid cooling of gravies and sauces to modified atmosphere packaging, from IQF freezing of berries to juice stripping, all the way to refrigerated transport.
SIAD, the first among all producers to introduce protective atmosphere packaging in Italy, supplies the FOODLINE range for MAP of fresh fruit and vegetables, fourth- and fifth-range products and preserves. Aroma+, patented and compliant with EC Regulation 1333/2008, developed in collaboration with Almi, combines food-grade gases and natural aromas to enhance the product’s olfactory qualities, keeping color and aroma unchanged until the end of shelf life.
The Kryos 2.0 system instantly reduces the temperature of sauces, gravies and creams in automatic mode, in batches or continuously, preserving the product’s organoleptic properties. For juices and food liquids, nitrogen stripping removes up to 70% of dissolved oxygen, counteracting rancidity and preserving aromas and colors. Nitrogen inertization in storage tanks protects oils and preserves from oxidation, increasing product life.
IQF freezing with liquid nitrogen allows every single piece to be frozen individually, ideal for berries and small-sized products. For distribution, SIAD supplies dry ice in pellets or carbonic snow for refrigerated transport, maintaining the cold chain without investment in insulated vehicles, with guaranteed preservation for up to 72 hours.
