Webinar changes
by Don Osborn 15 Jul '25

15 Jul '25

A couple of announcements about our webinar format and calendar. 1. Our "third Thursday" rhythm will be interrupted this month, so this month's edition will not be held on July 17. This is due to a conjuncture of scheduling issues. We will follow with information on a discussion of fonio, our millet of the month in July. 2. We are also working on a changed approach to producing and sharing videos on millets, which will work better as we move forward. The monthly webinar approach was well-suited for the International Year of Millets, but may not be ideal outside of the context of an annual observance such as a UN international year. With more flexibility on when we can schedule guests to record interviews, we should be able to develop a even more interesting line-up of episodes to release on a regular basis. Stay tuned!

Two recent research articles on millets
by Don Osborn 10 Jul '25

10 Jul '25

Here are two recent articles on millets, one focusing on postharvest technologies, and the other giving an overview. Hossam S. El-Beltagi, Mohamed Abdel-Haleem, Nagwa Khedr, Tarek A. Shalaby, Mohamed M. El-Mogy, and Emad Hamdy Khedr, "Millets as climate-resilient crops: Emerging technologies for sustainable postharvest management," Journal of Food Composition and Analysis, Vol. 147, 2025, 107999, ISSN 0889-1575. https://doi.org/10.1016/j.jfca.2025.107999 ( https://www.sciencedirect.com/science/article/pii/S0889157525008142) * Abstract: "Millets, a diverse group of small-grained cereals, are gaining global attention due to their remarkable nutritional benefits, climate resilience, and sustainability in agricultural systems. Despite their potential as a solution to pressing challenges in food security, climate adaptation, and malnutrition, millets remain underutilized, largely due to significant postharvest challenges. These include inefficient processing technologies, high postharvest losses, limited storage infrastructure, and short shelf life. Addressing these issues is essential to unlock the full potential of millets in sustainable food systems. This review highlights the major challenges in millet postharvest management, emphasizing the need for innovative and sustainable solutions. Emerging technologies such as hermetic storage, smart packaging, and digital tools are transforming millet value chains, enhancing their quality and marketability. Sustainable practices, including renewable energy-based processing, biodegradable packaging, and circular economy models, are further advancing environmental and economic sustainability. Additionally, case studies illustrate the practical applications of these approaches in various contexts, showcasing their scalability and impact. The review also identifies key research gaps and future directions, including the need for multidisciplinary approaches to enhance millet postharvest technologies, and improve value chain efficiency. By addressing these challenges holistically, millets can play a critical role in achieving global food security." * Keywords: Food security; Nutritional grains; Nanotechnology; Climate resilience; Hermetic storage * Millets covered: "pearl millet (Pennisetum glaucum), finger millet (Eleusine coracana), sorghum (Sorghum bicolor), foxtail millet (Setaria italica), and proso millet (Panicum miliaceum), little millet (Panicum sumatrense), and barnyard millet (Echinochloa spp.)" * Comment: Article addresses a key issue in developing markets for millets. Authors are from institutions in Egypt and Saudi Arabia. Unfortunately the full article is paywalled. ___ Mohanan MM, Vijayakumar A, Bang-Berthelsen CH, Mudnakudu-Nagaraju KK, Shetty R. "Millets: Journey from an Ancient Crop to Sustainable and Healthy Food." Foods. 2025 May 13;14(10):1733. doi: 10.3390/foods14101733. PMID: 40428513; PMCID: PMC12111017. https://pmc.ncbi.nlm.nih.gov/articles/PMC12111017/ * Abstract: "Millets, often known as 'nutri-cereals', have garnered renewed global interest due to their numerous health benefits, rich nutritional composition, resilience to extreme climatic conditions, and minimal environmental footprint. The advent of rice and wheat as staple foods in the 1960s led to drastic decline in millet cultivation worldwide. Recognizing the importance of millet, the United Nations (UN) declared 2023 as the International Year of Millets in an effort to accomplish Sustainable Development Goal 2 (SDG-2), i.e., zero hunger, by increasing millet production and fostering research and development to improve the integration of these grains into mainstream food systems. In recent years, global production of millets has surged, with India leading as the top producer. Millets are nutritionally advantageous, consisting of carbohydrates, antioxidants, and biologically active compounds such as flavonoids, carotenoids, phenolic acids, minerals, and vitamins. Incorporating millets into a balanced diet can help control and prevent diseases such as cardiovascular disease, diabetes, inflammation, and malnutrition due to their enriched vital nutrients, low glycemic index, and gluten-free nature. This indicates a transition of millets from an 'orphan crop' to being used as ingredients for products (with or without fermentation) that are nutrient-rich, climate-resilient, sustainable, and health-promoting." * Keywords: millets, sustainable food, gluten-free, health, nutrient-rich, climate-resilient * Millets covered: finger, pearl, sorghum, little, foxtail, proso, kodo, barnyard (Japanese & Indian), and browntop; attention also given to two so-called "pseudo-millets," amaranth & buckwheat * Comments: Brings together useful information on millets. Unfortunately shifts sometimes from plural into the singular (e.g., "Millet, one of the earliest cultivated domestic crops ..." rather than "Millets, among the earliest cultivated domestic crops ...").

Brewing with fonio
by Don Osborn 05 Jul '25

05 Jul '25

In a search for recent podcasts relating to fonio, I found that some of the most recent ones focus on the use of fonio in brewing beers. Here are 4, followed by my general comments. "Garrett Oliver Dishes on Fonio Rising; Plus, Breeze Galindo Discusses the Michael James Jackson Foundation for Brewing & Distilling," Brewbound Podcast, 2 Jan 2025 https://podcasts.apple.com/us/podcast/garrett-oliver-dishes-on-fonio-rising… (Jump to 50:03 for the segment with Garrett Oliver, which altho only about 10 min., is very good. Mr. Oliver is the brewmaster at Brooklyn Brewery, and collaborated with Chef Pierre Thiam of Yolélé Foods on a noted fonio beer brand.) "Fonio, Fonio, What The Heck Are You, Fonio?" Experimental Brewing (Episode 207), 14 April 2025 https://podcasts.apple.com/us/podcast/episode-207-fonio-fonio-what-the-heck… (There's mention of fonio in brewing at 21:25, and then a longer segment beginning at 27:30. This discussion with Ashton Lewis of Brewers Supply Group gets very technical.) "Garrett Oliver and Vinnie Cilurzo are Brewing for Impact With Fonio Grain," Craft Beer & BrewingMagazine Podcaast, 27 September 2024 https://podcasts.apple.com/us/podcast/garrett-oliver-and-vinnie-cilurzo-are… (Two noted craft brewers, Garrett Oliver, mentioned above, and Vinnie Cilurzo, of Russian River, share information about fonio and their own experiences in a wide ranging and sometimes technical discussion. Full duration 1 hr., 8 min.) "Fonio Friends, There's a New Grain in Town," False Bottomed Girls, 24 March 2025 https://podcasts.apple.com/us/podcast/fonio-friends-theres-a-new-grain-in-t… (The two podcast hosts discuss fonio and its use in brewing beer. Duration 44 min.) Comments on content of one or more of the above: * Fonio at the edge of the desert: Fonio does indeed grow in marginal areas including with low rainfall, but appears to be more common in areas with somewhat higher rainfall (savanna) and at elevation. Personally, my introduction to fonio was in the Plateau region of southern Togo (rainfall over 40" / 1000mm per year), and then the Futa Jalon region of Guinea (rainfall perhaps as high as 80" / 2300 mm). * Sand: The sand in fonio may come from a common traditional method of dehulling the grain - pounding in a mortar with sand. I'm not sure to what degree sand may be introduced in threshing and subsequent gathering of the seed. Also not sure whether mechanization of threshing and dehulling may eliminate the problem * Reason for marginalization of fonio as a crop: It's more complicated than a colonial plan to suppress its cultivation - without making excuses for colonialism. Fonio has always been labor intensive to harvest & process. relative to pearl millet, sorghum, corn, & arguably even rice. At the same time, in drier areas, pearl millet and sorghum, which are both indigenous staples, are more common crops. In humid areas, corn - introduced long ago - is unsurprisingly very productive, which has obvious appeal to smallholder farmers. Colonial regimes did push cash crops - such as peanuts in Senegal - and monocultures, and such policies certainly can compete with staple production. But I have not seen anything to suggest any active discouragement of fonio cultivation. * Fwiw, I personally don't drink alcoholic beverages, so can't comment on the fonio beer products mentioned, but if any of you do and can, please share your experience.

This Thursday (6/19) - webinar on processing sorghum for food
by Don Osborn 15 Jun '25

15 Jun '25

Dear all, Our Millets Webinar this month will shed light on the "hidden middle" of processing sorghum grain for food. We hope to advance current discussions of how to encourage more people to consume grain sorghum by helping demystify the processes by which it comes to us in comestible form, and to explore what the possibilities are of these processes for food innovation. We will be joined by Earl Roemer, whose bio follows. We'll also vary the webinar format a bit this time, "Earl Roemer is a fourth-generation agricultural producer and businessman from West Central Kansas with backgrounds in both animal and plant science. Earl has held state and national leadership roles in both the State of Kansas and National Sorghum Industry Organizations. Earl is the Founder and President of Nu Life Market. This company focuses on the production, milling, and processing of specific sorghum grains containing defined quality and chemistry characteristics for applications in the food and beverage industries. The sorghum grains utilized by Nu Life Market are produced under an extremely strict identity preservation and regenerative production management system by their team of growers to reduce carbon and other greenhouse gases being released into the atmosphere and utilize less of our natural resources in the production of the sorghum grains milled by this food company." Earl was among experts quoted in a recent Wall Street Journal feature about promoting sorghum as food in the US. Zoom details for the webinar follow the sig.

"Zahina" or "zahína" for marketing sorghum?
by Don Osborn 13 Jun '25

13 Jun '25

On the talk about marketing names for sorghum, the less-used Spanish name for this grain, zahína, seems to me (a non-Spanish speaker) like it might be an excellent possibility for sorghum-based products. Only possible slight drawback is that it has a secondary meaning of a thin flour porridge, or one that doesn't thicken (not sure how that works). Interestingly, Zahina (or Zaheena) in Arabic - زهينّا - is a woman's name meaning "intelligent." Back to the Spanish zahína, it traces back to an entirely different word in the Andalusian Arabic dialect (once spoken in Spain) that means ... sorghum. So there doesn't seem to be any really problematic meaning to watch out for. Anyway, it seems to me that this "zahina" could be a useful sorghum product or product line name, at least in English, but not to replace "sorghum" or "milo" in common parlance. How it might play in Hispanophone communities and countries would be another question. Does "sorgo" have the same mixed reception among Spanish speakers that "sorghum" is said to have in English? "Milo" - having mentioned it - is actually a very convenient way to refer to grain sorghum, altho apparently on farms in Kansas (the biggest producer of sorghum in the US) it's associated with feed for animals. Also, in English we don't generally have names for edible grains different from those of the crop (as they sometimes do in Chinese, for example, or as we in English have for some meats vs. the names of the animals they are taken from). Etymologically, "milo" may trace back to the Portuguese word for millet, "milho." Will leave it there, Don Don Osborn, PhD (East Lansing, MI, US) North American Millets Alliance

Funding for research on millets
by Don Osborn 07 Jun '25

07 Jun '25

Following up on Dipak's mention of funding issues, here are some thoughts and a proposal. Lack of funding for millets research has always been an issue, and that seems to be even more of an issue with US cuts to Federal research funding in general (without getting into the politics of it)./1 In 2023, Prof. James Schnable, Dipak's colleague at the University of Nebraska - Lincoln, was quoted as saying: "(Proso millet) is in this weird hole in the federal funding schemes, which is part of why we ended up using private money to start Dryland Genetics. Because it’s a grain, it doesn’t qualify for a lot of the specialty crop grants,"/2 I think that gap is if anything bigger and deeper in the case of other millets (and "alternative crops"). In that same article, Dr. Rob Myers at University of Missouri (who was instrumental in getting us to the Millets Webinars series in 2023) remarked how what might be a relatively minor grant for major crops could be a game changer in the case of millets (my wording)./2 I hear Dipak's mention of it in his recent post as reflecting the recent changes and cuts in ag research funding in the US generally (without getting into the politics of it), and alerting us to a critical need at this point in time that goes beyond the previous dearth of funding for millets. So here's a question: How might we - NAMA and the community of interest in millets - call attention to the need and opportunity for funding ongoing and new research on millets, and the potential costs of not funding such research? Can we and should we in such an effort highlight specific programs such as Dipak's which (if I understand correctly) are at risk? How might such an appeal address a range of public, commercial, and foundation possibilities? Please let me know what you think is possible and realistic (or productively ambitious). Don Don Osborn, PhD (East Lansing, MI, US) North American Millets Alliance Notes: 1. I turned up a bevy of articles from around the US in a Google search under "News" on "current state of agriculture research funding" 2.

Foxtail millet husks for bioplastics, sound absorption, & antimicrobials
by Don Osborn 05 Jun '25

05 Jun '25

We have previously discussed how proso millet husks are sometimes used for pillow fill. Foxtail millet husks would seem to be too small to be practical for such use. However, there is research on possible uses of this by-product - or actually of compounds in it - for other purposes. Those include bio-plastics, sound absorption materials, and antimicrobials. What are implications for potential uses of hulls of other small millets? ---- Akhil Babu, Abhirami R. Kumar, N.R. Amrutha, S. Madhurya, H.N. Punil Kumar, Jeevan Prasad Reddy, P.S. Keshava Murthy, Kokkarachedu Varaprasad, "Utilizing foxtail millet husk waste for sustainable new bioplastic composites with enhanced thermal stability and biodegradability," International Journal of Biological Macromolecules, Vol. 282, Part 5, 2024, https://doi.org/10.1016/j.ijbiomac.2024.137283 Abstract: Foxtail millet husk (FMH) is a byproduct that is not suitable for consumption and is often discarded as solid waste. However, it can be used as a raw material to develop novel bioplastic composites that transform agro-based leftovers into value-added goods. Herein, new bioplastic composites were developed from poly(lactic acid), poly(butylene adipate-co-terephthalate) and FMH based granules by Injection Molding. The required granules were generated via a solvent evaporation method. The resulted bioplastic composites were analyzed for their morphologies, mechanical properties, crystal structures, thermal stability, and melting and crystallization behaviors using various techniques, such as scanning electron microscopy, universal testing machine, X-ray diffraction, thermogravimetric analysis, and differential scanning calorimetry. Expressly, chemical bonding between FMH fibers and poly(lactic acid)/poly(butylene adipate-co-terephthalate) PLA/PBAT was confirmed through Fourier Transform infrared spectroscopy analysis. The inclusion of FMH lowered the impact strength of the PLA/PBAT combination, which was confirmed by mechanical analysis. Morphological findings confirmed that the PLA/PBAT combination had FMH aggregation. DSC thermograph revealed negligible differences in glass transition and melting temperatures of PLA/PBAT blend with and without FMH. The thermogravimetry results exhibit that the FMH can improve bioplastic thermal stability. The addition of FMH improved the biodegradability of the PLA/PBAT bioplastic composites. Overall, FMH waste can be repurposed for bioplastic composites with enhanced thermal stability and biodegradability. This reduces solid waste from agricultural practices and creates eco-friendly products. Further research could lead to more sustainable alternatives. ---- Balasubramanian, Dhayalini, Senthil Rajendran, Bhuvanesh Srinivasan, and Nirmalakumari Angamuthu. 2020. "Elucidating the Sound Absorption Characteristics of Foxtail Millet (Setaria Italica) Husk" Materials 13, no. 22: 5126. https://doi.org/10.3390/ma13225126 Abstract: The current study deals with the analysis of sound absorption characteristics of foxtail millet husk powder. Noise is one the most persistent pollutants which has to be dealt seriously. Foxtail millet is a small seeded cereal cultivated across the world and its husk is less explored for its utilization in polymer composites. The husk is the outer protective covering of the seed, rich in silica and lingo-cellulose content making it suitable for sound insulation. The acoustic characterization is done for treated foxtail millet husk powder and polypropylene composite panels. The physical parameters like fiber mass content, density, and thickness of the composite panel were varied and their influence over sound absorption was mapped. The influence of porosity, airflow resistance, and tortuosity was also studied. The experimental result shows that 30-mm thick foxtail millet husk powder composite panel with 40% fiber mass content, 320 kg/m3 density showed promising sound absorption for sound frequency range above 1000 Hz. We achieved noise reduction coefficient (NRC) value of 0.54. In view to improve the performance of the panel in low-frequency range, we studied the efficiency of incorporating air gap and rigid backing material to the designed panel. We used foxtail millet husk powder panel of density 850 kg/m3 as rigid backing material with varying air gap thickness. Thus the composite of 320 kg/m3 density, 30-mm thick when provided with 35-mm air gap and backing material improved the composite’s performance in sound frequency range 250 Hz to 1000 Hz. The overall sound absorption performance was improved and the NRC value and average sound absorption coefficient (SAC) were increased to 0.7 and 0.63 respectively comparable with the commercial acoustic panels made out of the synthetic fibers. We have calculated the sound absorption coefficient values using Delany and Bezlay model (D&B model) and Johnson–Champoux–Allard model (JCA model) and compared them with the measured sound absorption values. ---- P.P. Darshitha, Athul Ravi, P. Lasya, Maneesha Menon, G. Sivasubramanian, K.M. Sreekanth, K.M. Sreedhar, "Foxtail millet husk as an innovative biomass in the preparation of silica-silver composite with antimicrobial and free radicle scavenging activities," Materials Today: Proceedings, Volume 66, Part 4, 2022, Pages 1830-1836, https://doi.org/10.1016/j.matpr.2022.05.285. Abstract: The crop, Foxtail millet is rich in dietary fibres and proteins with low glycaemic index. Hence it qualifies as a regular food in the Indian diet. This has raised the importance of the millet in increased agricultural production. The husk is a waste that can be effectively utilised. Opaline silica is present as phytoliths in the spikelet of the husk. This can be solubilized and precipitated out. In this work, opaline silica was converted to sodium silicate and the composite was precipitated at a pH of 4 using the sol–gel technique. The amount of silica was first quantified using XRF. The results obtained from XRF correlated well with those obtained from thermogravimetric analysis (TGA). The chemical groups are identified using IR spectroscopy. The phase identification of opaline silica and silver was done by powder X-ray diffractometry. The morphological characterization of the composite revealed an irregular structure with particle dimensions of 1.880 μm to 10.82 μm. EDX analysis showed the existence of silver and silicon. Prepared composite was tested for anti-microbial action against five pathogens and was found to be comparable with antibiotics ciprofloxacin and ampicillin. The composite also presented outstanding scavenging action against 5 radicals with BHT as a standard. Don Osborn, PhD (East Lansing, MI, US) North American Millets Alliance
