The study aimed to compare the environmental impact, sensory properties, and nutritional profile of beef burgers with alternative burgers based on plant, insect, and mycoprotein biomass. Results showed that alternative burgers are more environmentally friendly than beef burgers, but only insect-based and soy-based options had satisfying sensory or nutritional properties. Pea-based and mycoprotein-based burgers were perceived as average in terms of environmental and sensorial perspectives. The study established a sustainability differentiation system for meat analogs in convenience products using a multicriteria framework including nutrient scoring, sensory testing, and Life Cycle Assessment.
Substitution of beef with alternative proteins is one practical trend taken by industry and consumers to reduce the negative impact of convenience products on the environment. Numerous products based on plant, insect and fungi proteins compete to replace beef burgers in an environmentally friendly and healthy way. At the same time, there is a lack of studies which assess different options from environmental impact perspective but also with consideration of production scales, recipes, nutritional values, and sensory properties. Therefore, the current study aimed to perform a holistic assessment (Life Cycle Assessment, sensory properties, and nutritional profile) of beef burgers in comparison to selected, alternative burgers, available on the market in Germany. The results indicated that alternative burgers based on plant, insect and mycoprotein biomass would be more environmentally friendly than beef burgers, but only a couple of them (insect-based and soy-based) have satisfying sensory or nutritional properties. Pea-based and mycoprotein-based burgers were perceived as average burgers from an environmental and sensorial perspective. The study demonstrated a sustainability differentiation system of meat analogs in convenience products using the multicriteria framework with inclusion of nutrient scoring, sensorial testing and Life Cycle Assessment.
