- W345651738 abstract "The environmental potential of an increased human consumption of grain legumes has been assessedusing life cycle assessment (LCA). The product type that has been studied is a sausage, and threevariants with different protein mix were included in the study: an animal product, an animal productwith some vegetable protein, and a fully vegetarian product. The animal product is based on the “HotDog”, manufactured by Swedish Meats in Orebro, Sweden. Site-specific data for the sausage factoryhave been obtained from that facility. The other recipes have been created using recipe software. Thefunctional unit in the study is “one kg sausage prepared and eaten in a household”. The protein contentis equal for all three products. Two scenarios were set up; one where 10% of the animal protein wassubstituted for a vegetable alternative; and one where a fraction of the sausages consumed wassubstituted for a vegetable product.Two kinds of vegetable proteins have been studied, soy and pea. The reason for including soy is thatno commercial pea product was found. Raw material and energy use, emissions, and waste data werecollected for involved materials and processes. Chosen impact categories were: global warmingpotential (GWP), acidification, and eutrofication. The net energy input to each product was alsocalculated, as well as land use, expressed in m2.The environmental impact of vegetable protein production is less than 10% of the impact of animalprotein production in all categories. The impact of pea protein is lower than the impact of soy protein.However, the substitution of 10% pea protein for animal protein in the hot dog only resulted in adecreased impact of about 5% due to a simultaneous change of recipe. To maintain certaincharacteristics of the Hot Dog the proportion of beef meat was increased in relation to pork. For the100% vegetable soy sausage the impact decreased by between 55 and 87% compared to the Hot Dog,for the three impact categories eutrofication, acidification and GWP.A hot spot analysis reveals that the meat production accounts for the absolute largest share of theenvironmental impact, with home transports as runner-up. Looking at the sausage factory processesonly, it can be seen that the peeling process (where a casing is removed from the sausage) accounts fora large impact, due to the steam production.The soy recipe is hypothetical in that it is constructed using a recipe software, due to that nomanufacturer was willing to participate with a vegetable recipe. Thus, the calculations of theenvironmental impact from the soy product are uncertain, apart from the impact of the soy protein.Also, the sensory properties are unknown.It is more environmentally efficient to use vegetables as a primary protein source, not to feed animalsbut to produce it for human consumption. The future potential of vegetable protein relies much on themarketing and acceptance of new products like the partially vegetable sausage that is presented inscenario 1." @default.
