1b. Approach (from AD-416):
New off-season crop development is critical to the future sustainability of the United States (U.S.) agriculture by reducing the farmer’s dependence on government subsidies for a select few commodity crops such as corn and soybeans, and by supplementing our need for energy without decreasing food production (food vs. fuel). A number of off-season new crops (pennycress and coriander) will be further developed for the U.S. by developing cost effective industrial products and processes from these agricultural feedstocks. A collaborative effort to the development of pennycress, camelina, and coriander will occur: 1) Off-season germplasm development will be supported through developing analytical methods to rapidly analyze glucosinolates, oil, and seed quality. Additionally, off-season crop germplasm resources will be surveyed and publicly accessible databases generated; 2) Development of chemical and physical processes that enable the commercial production of oils, meal, gums, and proteins in off-season oilseed crops. In order to produce and demonstrate economic data, the new crop raw materials will be produced in pilot scale quantities. 3) Development of novel industrial chemicals and processes through organic synthesis based on off-season crop raw materials derived above. Products to be developed include biodegradable lubricants, biobased viscosity modifiers, lubricant additives, cosmetics, and chelating or sequestering agents. Overall, this research will lead to the development and expansion of off-season oilseed crops which will help diversify the U.S. farm as well as expand the U.S. arsenal of industrial biofriendly chemicals and processes.
3. Progress Report:
New off-season crop development is critical to the future sustainability of U.S. agriculture by reducing farmer’s dependence on government and by supplementing our need for biobased products without decreasing food production. Past efforts by ARS scientists in Peoria, Illinois, have led to the development of pennycress (Thlaspi arvense L.) as an off-season rotation crop. Pennycress continued to be commercially grown (by a St. Louis, Missouri based company) during the 2017-2018 season. Pennycress oil has properties suitable for the development of biofuels – i.e. as an aviation jet fuel drop-in replacement. Commercialization and collaborative research efforts continue as ARS scientists provided consultative oversight for production and processing the seeds for oil/meal/protein and have also developed other potential industrial products from the oil. Other off-season crops are also being evaluated as possible commercial oilseed crops. For example, Camelina (C. sativa), which the United States Navy chose as their feedstock for an aviation biofuel, was studied in Peoria, Illinois, as a late season rotation crop with winter wheat. Camelina rotation studies and evaluations are positive and ongoing. Additionally, ARS scientists have also achieved successful functionalization of camelina oil to a corresponding polyketone derivative which has shown unusual chelating character for silver (Ag+) and mercury (Hg2+) ions. ARS scientists yielded a newly-developed integrated process for coriander that produces essential oil, edible oil, and protein isolates, thus adding value to the coriander crop. The results demonstrated that a protein concentrate could be a co-product from a dual oil process for dehulled coriander seeds, with nutritional and functional properties that are suitable for both food and non-food. The ARS scientists, in Peoria, Illinois, responsible for these results were awarded the 2018 Best Paper Protein and Co-products division Engineering and Technology category by the Journal of the American Oil Chemists Society. Finally, one of the most successful products developed by ARS scientists, in Peoria, Illinois, have been the estolides which are a vegetable-based-type lubricant. Commercialization efforts continue as ARS scientists provided consultative oversight for scale-up production and the development of new products and applications.
1. Repelling biting flies. Biting or blood-sucking insects (flies, mosquitos, ticks, and bed bugs) can transmit various diseases that cause major health concerns and economic losses for both animals and humans worldwide. Currently, there are no effective pesticides available for use against either biting stable flies or biting face flies. ARS scientists in Peoria, Illinois, and Lincoln, Nebraska, identified and developed a new bio-based insect formulation repellent designed to meet the challenges posed by these insect vectors. These researchers discovered that naturally derived fatty acids from coconut oil function as a very effective biobased repellent having broad repellency and long effectiveness against multiple blood-sucking insect vectors. The all-natural aqueous formulation, developed in Peoria, Illinois, provided promising results in field trials conducted on cattle in North Platte, Nebraska. The current biting fly issue in the United States costs the cattle industry over $2.4 billion annually. This new finding will aid cattle farmers and rangers with additional products to address their biting insect issues.
