“…When comparing with other protein-rich products, both TM protein extracts have eco-efficiency scores comparable to that of the lupin seed protein isolate and lower than that of other vegetable protein sources (Faba bean protein ingredient as well as microbial protein and soy protein isolate). The large error bars for microbial protein and soy protein isolate indicate the variations in eco-efficiency scores for these two protein sources, which are due to different production contexts . Indeed, the results for the soy protein isolate were obtained from 10 different studies, resulting in different GWP scores.…”

“…The large error bars for microbial protein and soy protein isolate indicate the variations in eco-efficiency scores for these two protein sources, which are due to different production contexts. 50 Indeed, the results for the soy protein isolate were obtained from 10 different studies, resulting in different GWP scores. In addition, a sensitivity analysis was performed for microbial protein by comparing the impact of different energy sources (hydropower vs average electricity mix in Finland) to produce this protein type, which led to different GWP scores.…”

The potential of edible insects as a novel ingredient in high value-added products has been investigated to find alternatives to conventional protein sources. Low acceptability of entomophagy is the main challenge, but the development of insect protein-based food products could improve consumer perception. Nevertheless, while insect rearing has a low environmental impact, there are no studies on environmental performance related to the production of insect protein extracts. In this work, Tenebrio molitor (TM) protein extracts were produced by protein alkaline solubilization (one or two steps) with or without isoelectric precipitation, and the global warming potential (GWP) related to the different protein extracts was calculated. The optimal lipid extraction rate was 86.9% using a hexane: ethanol ratio of 1:2. Protein extraction and purification rates ranged from 54.7 to 94.4% and 80.0 to 49.4%, respectively. Depending on the protein purification and allocation method applied, the GWP of a TM protein extract was 3,050 to 10,871 kg CO 2 eq. per ton of the extract produced. Eco-efficiency scores associated to TM proteins extracts were between those published with plant-based and animal-based protein sources, confirming the interesting environmental performance of insectderived protein ingredients.

“…Soy whey is the wastewater generated by soaking and boiling soybeans, or during tofu curd draining and soy protein isolate production . Soy whey is produced in abundant quantities, as approximately 9 kg of soy whey is generated from each kg of tofu produced. ,− Depending on the source and on the processing conditions, soy whey contains proteins in the range of 0.3–8.2 g/L, has a pH in the range of 5.4–6.6, and a high concentration of organic compounds. , This byproduct has a markedly limited shelf life (approximately 1 day), and its disposal remains challenging due to its organic load . In particular, the treatment of soy industry wastewater is expensive as a result of the high BOD and COD (6.8 and 12 g/L, respectively), and it is estimated to be on the order of 0.13 $/kg .…”

Turning Food Protein Waste into Sustainable Technologies

For each kilogram of food protein wasted, between 15 and 750 kg of CO2 end up in the atmosphere. With this alarming carbon footprint, food protein waste not only contributes to climate change but also significantly impacts other environmental boundaries, such as nitrogen and phosphorus cycles, global freshwater use, change in land composition, chemical pollution, and biodiversity loss. This contrasts sharply with both the high nutritional value of proteins, as well as their unique chemical and physical versatility, which enable their use in new materials and innovative technologies. In this review, we discuss how food protein waste can be efficiently valorized not only by reintroduction into the food chain supply but also as a template for the development of sustainable technologies by allowing it to exit the food-value chain, thus alleviating some of the most urgent global challenges. We showcase three technologies of immediate significance and environmental impact: biodegradable plastics, water purification, and renewable energy. We discuss, by carefully reviewing the current state of the art, how proteins extracted from food waste can be valorized into key players to facilitate these technologies. We furthermore support analysis of the extant literature by original life cycle assessment (LCA) examples run ad hoc on both plant and animal waste proteins in the context of the technologies considered, and against realistic benchmarks, to quantitatively demonstrate their efficacy and potential. We finally conclude the review with an outlook on how such a comprehensive management of food protein waste is anticipated to transform its carbon footprint from positive to negative and, more generally, have a favorable impact on several other important planetary boundaries.

“…has been one of the major sources of protein and oil for human food and livestock feed in Canada ( Singh and Hymowitz, 1999 ). Demand for this “king of beans” has been steadily increasing year-over-year due to its nutritional values for human and livestock, as well as industrial applications ( Thrane et al, 2017 ). This growing demand has created a significant market for varieties with increased seed quality and yield, along with a range of improved agronomic traits.…”

Multi-Parent Advanced Generation Inter-Cross (MAGIC) populations are emerging genetic platforms for high-resolution and fine mapping of quantitative traits, such as agronomic and seed composition traits in soybean (Glycine max L.). We have established an eight-parent MAGIC population, comprising 721 recombinant inbred lines (RILs), through conical inter-mating of eight soybean lines. The parental lines were genetically diverse elite cultivars carrying different agronomic and seed composition characteristics, including amino acids and fatty acids, as well as oil and protein concentrations. This study aimed to introduce soybean MAGIC (SoyMAGIC) population as an unprecedented platform for genotypic and phenotypic investigation of agronomic and seed quality traits in soybean. The RILs were evaluated for important seed composition traits using replicated field trials during 2020 and 2021. To measure the seed composition traits, near-infrared reflectance (NIR) was employed. The RILs were genotyped using genotyping-by-sequencing (GBS) method to decipher the genome and discover single-nucleotide polymorphic (SNP) markers among the RILs. A high-density linkage map was constructed through inclusive composite interval mapping (ICIM). The linkage map was 3,770.75 cM in length and contained 12,007 SNP markers. Chromosomes 11 and 18 were recorded as the shortest and longest linkage groups with 71.01 and 341.15 cM in length, respectively. Observed transgressive segregation of the selected traits and higher recombination frequency across the genome confirmed the capability of MAGIC population in reshuffling the diversity in the soybean genome among the RILs. The assessment of haplotype blocks indicated an uneven distribution of the parents’ genomes in RILs, suggesting cryptic influence against or in favor of certain parental genomes. The SoyMAGIC population is a recombined genetic material that will accelerate further genomic studies and the development of soybean cultivars with improved seed quality traits through the development and implementation of reliable molecular-based toolkits.
