“…Bioplastic applications for films, foams, etc., using other protein types, such as gliadins, whey, and soy protein, have clearly shown a correlation between protein molecular reorganization, including chemical cross-linking, and functional properties. − Previous studies have pointed out key parameters, such as selection of genetic materials (G) and cultivation environments (E), for a successful molecular organization and polymerization of plant proteins. , Furthermore, protein separation methods have been found to significantly influence the aggregation level of proteins as well as their ability to depolymerize before processing. , …”

“…14,15 Furthermore, protein separation methods have been found to significantly influence the aggregation level of proteins as well as their ability to depolymerize before processing. 16,17 Previous successful work on the use of plants as a "green factory" for developing high-strength gluten films led us to further focus on the selection of protein source and treatments to resolve the understanding of protein material properties and their relationship to protein aggregation. Therefore, the aim of this study was to combine different factors, such as genetics, environment, and protein separation procedures, and to evaluate whether and how these factors could be used to reshape and steer the secondary structure and nanoscale morphologies in glutenin proteins.…”

A combination of genotype, cultivation environment, and protein separation procedure was used to modify the nanoscale morphology, polymerization, and chemical structure of glutenin proteins from wheat. A low-polymerized glutenin starting material was the key to protein–protein interactions mainly via SS cross-links during film formation, resulting in extended β-sheet structures and propensity toward the formation of nanoscale morphologies at molecular level. The properties of glutenin bioplastic films were enhanced by the selection of a genotype with a high number of cysteine residues in its chemical structure and cultivation environment with a short grain maturation period, both contributing positively to gluten strength. Thus, a combination of factors affected the structure of glutenins in bioplastic films by forming crystalline β-sheets and propensity toward the ordered nanostructures, thereby resulting in functional properties with high strength, stiffness, and extensibility.

Crambe (Crambe abyssinica Hochst): A Non-Food Oilseed Crop with Great Potential: A Review

et al. 2020

Crambe (Crambe abyssinica Hochst) is an oilseed crop in the Brassicaceae family. Crambe’s ability to survive in diverse environmental conditions, its unique oil composition, the high oil content, suitability for the production of slip agents for plasticizers, the capacity to be easily included in common crop rotations, and its adaptability to equipment used for small grain cultivation has renewed the interest in this emerging crop. Crambe is considered one of the main sources of erucic acid, which can be up to 60% of its seed oil content. Erucic acid (C22:1) is a fatty acid with industrial importance since it is used to produce erucamide, key ingredient in the plastic industry. Inclusion of crambe into crop rotations can be beneficial because of its short life cycle, low fertility requirements, resistance to pest and diseases, and relative drought tolerance. Currently high erucic acid rapeseed (Brassica napus L.) (HEAR) is the principal source for erucic acid. However, the risk of contaminating food quality rapeseed (i.e., canola) by cross-pollination and the negative impact on climate, due to high inputs, are potential limitations to expand HEAR cultivation. Crambe has thus great potential to, at least, partially replace HEAR as a source of erucic acid, if the current knowledge-gap in agronomic management and crop improvement (seed yield and quality) can be addressed. Seed yield needs to be increased to be able to compete with HEAR. In addition, reducing glucosinolates and fiber in crambe meal may increase its inclusion in monogastrics rations. The objective of this review was to compile and summarize new and existing information on agricultural practices in crambe production and management to identify gaps in knowledge and areas for future research to increase the cultivation of crambe.
