NEW YORK (Reuters) -Unilever’s Magnum ice cream business, set to publicly list in November, plans to use Chilean start-up NotCo’s artificial intelligence to reformulate products and create new ones. Magnum plans to use NotCo’s AI to look at the calories in ice cream, make new plant-based products and help manage rising commodity costs, said Zbigniew Lewicki, chief research, design and innovation officer at the Magnum Ice Cream Company, in a statement. Lewicki said consumers want to indulge but are also looking for smaller portions and more sustainable products.
