Abstract
Because of their high nutritional value, short growth cycle, and diverse sensorial characteristics, microgreens have gained increasing attention as a potential candidate in the fight against food and nutritional insecurity. According to USDA Economic Research Report No. (ERR-270), an estimated 11.1 percent of U.S. households were food insecure at least some time during the year in 2018, meaning they lacked access to enough nutritious food for an active, healthy life for all household members. Suboptimal diet is one of the leading risk factors for poor health, both globally and in the US, and is responsible for up to 45% of all cardiometabolic disease (CMD) deaths. (Lim et al., 2010; Murray et al., 2013; Micha et al., 2017). In the U.S. in particular, suboptimal diets accounts for 18.2% of diet-related chronic disease health care costs in the US, and the cost estimate is staggering. (Jardim et al., 2019). Annual diet-related cardiometabolic disease costs alone through 2019 are estimated at $301/person, which translates to approximately $50.4 billion per year. (Jardim et al., 2019).
Data on the benefits of consuming high levels of phytonutrients in vegetables to prevent or ameliorate chronic disease are very persuasive. (Wagner, 2013). It is well established that there are many minor components in plant-derived foods – called phytonutrients – that elicit biologic responses in mammalian systems that are consistent with reducing risk factors of diet-related chronic diseases. (Beecher, 1999). For example, broccoli vegetables produce glucosinolates and isothiocyanates. These phytonutrients enzymatically degrade to form another beneficial compound, sulfurophane, during food digestive processes. Sulfurophane, is known to promote antioxidant, antimicrobial, anticancer, and other metabolic health functions in the human body.
In general, microgreens are edible crop plants that are only grown to the first true leaf stage and that feature short, repeatable cultivation cycles - around seven to ten days per harvest. Within these short cycles, microgreens are capable of producing glucosinolates and isothiocyanates at significantly higher levels than their mature vegetable counterparts. The unique characteristics of microgreen phytonutrients provide strong motivation to preserve their function-enhancing properties as they move from farm-to-table.
The purpose of this study is to assess the feasibility and viability of microgreen production on an industrial scale. In the course of assessment, two undergraduate student participants of a Research Experience for Undergraduates program hosted at Prairie View A&M University performed a preliminary technoeconomic analysis on the cultivation, harvest, and post-processing of broccoli microgreens in Texas. Results from the analysis will be presented and discussed in this talk.
