Title: Agri-food tech’s building block: narrating protein, agnostic of source, in the face of crisis
Inventive producers in Silicon Valley and other innovations sectors are going beyond the simulated animal products of plant-based proteins and cellular technologies to produce a third generation of protein products, making protein the leading edge of high tech food innovation. Since innovators draw on sources not generally recognized as food these products are speculative as both foods and investments. Building on scholarship that examines edibility formation of so-called alternative proteins, we show the deployment of three interlocking narratives that make novel protein products both edible and investible: protein is ubiquitous and protean, which provides myriad opportunities for technological transformation; its longtime associations with vigor, strength and energy, along with current day obsessions with the negatives of fats and carbohydrates, renders it the one remaining macronutrient that it is unequivocally good; and widely circulated discourses of both future shortages and the problems with contemporary livestock production makes producing more an almost indisputable solution. While innovators and investors act as if protein needs this sector to solve an impending crisis and bring its possibilities to fruition, we suggest the inverse—that without protein the sector would be nearly barren of novelty and food, much less the disruption and impact routinely claimed.  more » « less

    While the tech sector has seized upon the food system as an area in which it can have a major impact, innovators within the agri-food tech domain are dogged by concerns about public acceptance of technologies that may be controversial or simply not of interest. At the same time, because they operate within an investor-dependent political economy, they must demonstrate that the public will consume the products they are creating. To both secure markets and legitimate their approaches to problem-solving, entrepreneurial innovators draw on three existing imaginaries of consumers, each of which articulates with a particular tendency they have pursued in problem-solving. Reflecting a tendency of solutionism, those promoting technologies that promise minimal processing and/or short or traceable supply chains invoke a health- and eco-conscious consumer. In keeping with technofixes, those promoting technologies of mimicry invoke a complacent consumer. Reflecting the tendency toward scientism in problem-solving and related projections of public knowledge deficits, those promoting potentially controversial technologies invoke a fearful consumer and embrace transparency to inform and assure such consumers. By promising future consumers who will willingly accept emerging technologies, each of these imaginaries seeks to resolve – for investors – potential problems of consumer acceptance generated by the particular approaches to problem-solving innovators have adopted. While STS scholars have shown how public-facing engagement exercises and policy work are often limited by deficit-driven imaginaries of the public, in these investor-facing spaces possible objections are both imagined and overcome without any interaction with actual publics.

    Along with seeking to eliminate the inhumane conditions and slaughter involved in animal protein production, alternative protein companies aspire to ameliorate its environmental impacts. They claim to do so by making edible protein from (nearly) nothing, drawing on abundant or mundane resources that will presumably not be missed or have no negative externalities, or “upcycling” byproducts that would otherwise be wasted—to de-materialize in other words. At the same time, these entrepreneurs promise their substitutes will be nutritionally analogous to or better than animal-based proteins and have only salubrious effects on human bodies. Drawing on data collected on alternative protein companies that are based in or have come through Silicon Valley, this article catalogs and examines company representations of their various de-materialization promises. We find that attempting to meet the tripartite, yet competing imperatives of Silicon Valley innovation, namely disruption, transparency, and secrecy, results in representations of processes that obfuscate more than they reveal. The resulting obfuscation is not simply the intentional veiling of pernicious processes; more than selling specific food products, Silicon Valley food tech entrepreneurs aspire to bring a new food system into being and convince their audiences that this food future is both better and achievable. Nevertheless, their representational practices make it difficult, if not impossible, for the public—or anyone really—to meaningfully assess the promises and their potential consequences, much less hold their proponents accountable to anything but pecuniary concerns.

    Food waste is a major issue that is increasingly affecting our environment. More than one-third of food is wasted, resulting in over $400 billion in losses to the U.S. economy. While composting and other small recycling practices are encouraged from person-to-person, it is not enough to balance the net loss of 80 million tons per year. Currently, one of the most promising routes for reducing food waste is through microbial fermentation, which can convert the waste into valuable bioproducts. Among the compounds produced from fermentation, 2,3-butanediol (2,3-BDO) has gained interest recently due to its molecular structure as a building block for many other derivatives used in perfumes, synthetic rubber, fumigants, antifreeze agents, fuel additives, and pharmaceuticals. Waste feedstocks, such as food waste, are a potential source of renewable energy due to their lack of cost and availability. Food waste also possesses microbial requirements for growth such as carbohydrates, proteins, fats, and more. However, food waste is highly inconsistent and the variability in composition may hinder its ability to be a stable source for bioproducts such as 2,3-BDO. This current study focuses specifically on post-consumer food waste and how 2,3-BDO can be produced through a non-model organism, Bacillus licheniformis YNP5-TSU during non-sterile fermentation. From the dining hall at Tennessee State University, 13 food waste samples were collected over a 6-month period and the compositional analysis was performed. On average, these samples consisted of fat (19.7%), protein (18.7%), ash (4.8%), fiber (3.4%), starch (27.1%), and soluble sugars (20.9%) on a dry basis with an average moisture content of 34.7%. Food waste samples were also assessed for their potential production of 2,3-BDO during non-sterile thermophilic fermentation, resulting in a max titer of 12.12 g/L and a 33% g/g yield of 2,3-BDO/carbohydrates. These findings are promising and can lead to the better understanding of food waste as a defined feedstock for 2,3-BDO and other fermentation end-products.

    Abstract Glycerol monolaurate (GML) is a naturally occurring antimicrobial agent used commercially in numerous products and food items. GML is also used as a homeopathic agent and is being clinically tested to treat several human diseases. In addition to its anti-microbial function, GML suppresses immune cell proliferation and inhibits primary human T cell activation. GML suppresses T cell activation by altering membrane dynamics and disrupting the formation of protein clusters necessary for intracellular signaling. The ability of GML to disrupt cellular membranes suggests it may alter other cell types. To explore this possibility, we tested how GML affects human B cells. We found that GML inhibits BCR-induced cytokine production, phosphorylation of signaling proteins, and protein clustering, while also changing cellular membrane dynamics and dysregulating cytoskeleton rearrangement. Although similar, there are also differences between how B cells and T cells respond to GML. These differences suggest that unique intrinsic features of a cell may result in differential responses to GML treatment. Overall, this study expands our understanding of how GML impacts the adaptive immune response and contributes to a broader knowledge of immune modulating monoglycerides.

    Natural proteins present a sustainable and biocompatible alternative to conventional fossil fuel-derived plastics, with versatile applications in fields ranging from medicine to food packaging. Extending our previous research on silk–corn zein composites, this study utilizes soy protein—another plant protein extensively employed within biomedical applications—in conjunction with silk fibroin proteins extracted from a variety of domestic (Mori and Thai) and wild (Muga, Tussah, and Eri) silkworm species. By combining these proteins in varying ratios (0%, 10%, 25%, 50%, 75%, 90%, and 100%), silk–soy films were successfully fabricated with high miscibility. The structural and thermal stability of these films was confirmed through various characterization techniques, including Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM). Structural refinements were then achieved through post-water annealing treatments. After annealing, it was observed that when soy protein was introduced into both types of silk, the silks exhibited a greater amount of intermolecular and intramolecular β-sheet content. This phenomenon can be attributed to soy’s intrinsic ability to self-assemble into β-sheets through electrostatic and hydrophobic interactions, which also improved the overall thermal stability and morphology of the composite films. The unique self-assembling properties of soy and its ability to promote β-sheet formation facilitate the customization of the silk source and the soy-to-silk ratio. This adaptability establishes protein-based thin films as a versatile and sustainable option for diverse applications in fields such as medicine, tissue engineering, food packaging, and beyond.
