SUSTAINABILITY FEED & ADDITIVE MAGAZINE February 2025 63 Nutritional evaluation of former food products intended for pig nutrition by Giromini et al (2017) referred to processed former foodstuffs as a "fat-enriched version of cereal grains" because they contain more fat while still providing a similar amount of starch. This makes them particularly valuable for compound feed production, where mixing fats with other ingredients is normally an additional step in the processing. Since the fats in former foodstuffs are already integrated into the product, they simplify the feed production process while providing a rich energy source and nutrients for animals. A LOW CARBON FOOTPRINTING VALUE The agri-food industry is increasingly scrutinized for its environmental impact and sustainability practices. In this context, feed sourcing and production play a significant role in driving these impacts.
