Detailed background data
It has been assumed that the food processing industry is located in Denmark. Ingredients include only onion, flour and oil, salt is neglected. An estimate is made of the mass balance of frying, based on the dry mass of the product vs. raw onions. Flour input is estimated based on a home-made recipe (kitrusy 2020), looking at the ratio flour/onion in the ingredients. Input of oil is assumed to equal the fat content in the finished product. Manufacturing includes only energy for frying, with a factor for home-cooking of 7.5 MJ/kg product (Foster et al. 2006), assumed as natural gas. 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: Open Food Facts (2020ac); Foster et al. (2006); Kitrusy (2020).
