SOL users active in this field have to meet the needs of consumers with products that are more and more characterised by naturalness and safety, availability and wideness of range, convenience and practicality. SOL studies tailor-made solutions for its clients, assisting them in order to raise the qualitative standard of their products. In order to obtain higher quality products than those that would be produced using traditional methods, many kinds of food are deep-frozen using liquid nitrogen or carbon dioxide, others are packed in modified atmosphere controlled with nitrogen, which preserves their aesthetic and organoleptic features. Cuttings and plants are treated in greenhouses with atmospheres rich in carbon dioxide in order to accelerate and improve their growth, while fish are subjected to intensive breeding by using oxygen. Spices and coffee are ground at a very low temperature using liquid nitrogen to preserve their aroma and quality.
