Siga has developed a scientific methodology, published in 2020 (Food & Function, DOI: 10.1039/C9FO02271F) to evaluate the degree of processing of food. In a virtuous effort, Siga awards best products of their categories with medals, for the best formulated and more authentic ones. With its expertise, Siga advises and guides every contributor of the food chain (mass catering, manufacturers, distributors) in their transition to a truer food offer, by evaluating their products, locating them on the market, training teams on the ultra-processing stakes, to (re)formulate products and promote transparency. Simultaneously, Siga helps Health & Nutrition professionals who want to include the ultra-processing concept to their professional activities, with a complete Kit and guide to download for free. In addition to these activities, Siga also makes available its mobile app for free to every consumer, in order to guide them to make the best choice for their health : the most authentic products, with the least processing.
