Soya sauce
Climate footprint in kg CO2e/kg
Detailed background data
It has been assumed that the food processing industry is located in Denmark. Ingredients obtained from Ariza (2020). Nutritional composition from Kikkoman product in Open Food Facts (2020ad). A coarse mass balance is done to calculate the amount of soy sauce cake byproduct. This mass balance uses the product density according to FAO (2012) of 1.12 kg/L, the amount of water and dry mass in ingredients, and the amount of water and dry mass in the product. The amount of by-product in dry mass is calculated as the amount of dry mass not incorporated in the product. Energy use is approximated by ketchup production (Andersson et al. 1998). Retail is modelled assuming the following storage: Ambient. See more details as well as literature references in the methodoly report on: www.denstoreklimadatabase.dk.
Data on inputs and outputs of the food processing industry is modelled using: Ariza (2020ad); Open Food Facts (2020); Andersson et al. (1998); FAO (2012).
