  • Observations on the Malting of Ancient Wheats: Einkorn, Emmer and Spelt
    fermentation Article Observations on the Malting of Ancient Wheats: Einkorn, Emmer and Spelt Alice Fujita, Senay Simsek and Paul B. Schwarz * Department of Plant Sciences, North Dakota State University, Fargo, ND 58108, USA; [email protected] (A.F.); [email protected] (S.S.) * Correspondence: [email protected]; Tel.: +1-701-231-7732 Received: 25 November 2020; Accepted: 10 December 2020; Published: 14 December 2020 Abstract: There have been tremendous marketing efforts and consumer interest in the so-called ancient grains. Einkorn, emmer and spelt, which are sometimes referred to as ancient wheats, are frequently included in this category, and have gained some attention among brewers. The objective of the current study was to compare the malting behavior and quality of einkorn, emmer and spelt cultivars obtained from the same growing environment. Aside from standard malt quality traits, the levels of β-amylase, protease, xylanase, wort arabinoxylans and wort phenolic acids were measured. While protein levels of the samples were higher (11.4–14.0%) than normally selected for wheat malt, the results indicated that malts of acceptable quality in terms of extract and amylolytic activity can be prepared from the three grain types. However, the ideal malting protocol will likely differ between the grains. The kernels of einkorn are significantly smaller, and steep hydration and malt modification are quicker. In terms of potential health benefits from antioxidant capacity and dietary fiber, wort from einkorn trended to higher levels of free and conjugated ferulic acid, as well as high-molecular-weight arabinoxylan. Keywords: arabinoxylan; brewing; einkorn; enzyme activity; emmer; malt; phenolic acid; spelt; and sprouting 1.

  • Nutritional Value and Bioactive Compounds in Andean Ancient Grains †
    Proceedings Nutritional Value and Bioactive Compounds in Andean Ancient Grains † Ritva Repo-Carrasco-Valencia Centro de Investigación e Innovación en Productos Derivados de Cultivos Andinos CIINCA, Universidad Nacional Agraria La Molina, Avenida La Molina s/n Lima 18, Lima 15024, Peru; [email protected] † Presented at the 2nd International Conference of Ia ValSe-Food Network, Lisbon, Portugal, 21–22 October 2019. Published: 3 August 2020 Abstract: Quinoa (Cheopodium quinoa), kañiwa (Cheopodium pallidicaule), kiwicha (Amaranthus caudatus) and tarwi (Lupinus mutabilis) are ancient crops from the Andean region of South America. Recently, interest in these crops has grown, and worldwide demand for them has increased considerably. The aim of this study was to study the bioactive compounds and nutritional compositions of different varieties/ecotypes of quinoa, kañiwa, kiwicha and tarwi. Proximate, mineral, dietary fibre, fatty acid and amino acid compositions were evaluated. The content of phenolic compounds, tocopherols and phytosterols, and the folic acid and antioxidant capacity, were determined as well. The protein content of the grains was between 13.00% and 20.00%. More important than protein quantity is protein quality, which is demonstrated by the composition of the amino acids. All analysed grains, and especially the kañiwa, had very high lysine content. This amino acid is especially important in vegetarian diets because it is the limiting amino acid in cereal protein. The content of the total phenolic compounds in the studied grains was 27–58 mg gallic acid/100 g of sample. In quinoa, the principal flavonoids found were quercetin and kaempferol, in kañiwa quercetin and isorhamnetin. In kiwicha, no detectable amounts of flavonoids were found.

The Macrobotanical Evidence for Vegetation in the Near East, c. 18 000/16 000 B.C to 4 000 B.C. Abstract Vegetation during the glacial period, post-glacial warming and the Younger Dryas does not seem to have been affected by human activities to any appreciable extent. Forest expansion at the beginning of the Holocene occurred independently of human agency, though early Neolithic farmers were able to take advantage of improved climatic conditions. Absence of macrobotanical remains precludes discussion of possible drought from 6,000 to 5,500 ВС. By farming, herding, and fuel-cutting, human populations began to have an impact on the landscape at different times and places. Deleterious effects of these activities became evident in the Tigris-Euphrates drainage during the third millennium ВС based on macrobotanical evidence from archaeological sites.

The assay was applied to a set of 300 samples, including 15 cultivars each of common wheat, spelt, durum wheat, emmer and einkorn cultivated at four locations in Germany in the same year. The total protein content was equally influenced by location and wheat species, however, gliadin, glutenin and gluten contents were influenced more strongly by wheat species than location. Einkorn, emmer and spelt had higher protein and gluten contents than common wheat at all four locations. However, common wheat had higher glutenin contents than einkorn, emmer and spelt resulting in increasing ratios of gliadins to glutenins from common wheat (< 3.8) to spelt, emmer and einkorn (up to 12.1). With the knowledge that glutenin contents are suitable predictors for high baking volume, cultivars of einkorn, emmer and spelt with good predicted baking performance were identified.

  • Wheat Improvement: the Truth Unveiled
    Wheat Improvement: The Truth Unveiled By The National Wheat Improvement Committee (NWIC) From wheat farmers to wheat scientists, we know consumers are yearning for more transparency and trust within their food “system.” We understand those concerns as consumers ourselves. In an effort to give consumers full scientific knowledge of how wheat has been improved over the years, we have worked together to publish a concise response to recent claims made by Dr. William Davis. The National Wheat Improvement Committee has compiled the following responses to Davis’ slander attack on wheat’s breeding and science improvements. Responses were developed with a scientific and historical perspective, utilizing references from peer-reviewed research and input from U.S. and international wheat scientists. Wheat Breeding & Science The wheat grown around the world today came from three grassy weed species that naturally hybridized around 10,000 years ago. The past 70 years of wheat breeding have essentially capitalized on the variation provided by wheat’s hybridization thousands of years ago and the natural mutations which occurred over the millennia as the wheat plant spread around the globe. There is no crop plant in the modern, developed world – from grass and garden flowers, to wheat and rice – that is the same as it first existed when the Earth was formed, nor is the environment the same. There is no mystery to wheat breeding. To breed new varieties, breeders employ two basic methods: Conventional crossing involves combining genes from complementary wheat plant parents to produce new genetic combinations (not new genes) in the offspring. This may account for slightly higher yield potential or disease and insect resistance relative to the parents.

  • Qualities of Einkorn, Emmer, and Spelt
    Qualities of Einkorn, Emmer, and Spelt Frank J. Kutka Farm Breeding Club Co-Coordinator Northern Plains Sustainable Agriculture Society Einkorn | Favored for adding excellent flavor to foods. | Suitable for baked products, some good for bread. | Higher lipid content than bread wheat (4.2 vs. 2.8 g/100g. | Usually high in minerals although low in Cadmium. | Usually higher in protein, lutein, and Vitamin E; Lower in total phenols. | Has same allergenic proteins as other wheats but may be lower in some of the gliadins that cause responses in those with celiac disease: more research is needed. Emmer | Favored for adding excellent flavor to foods. | Recommended for children and new mothers in Ethiopia and for diabetics in India. | Gluten varies from very low to higher than bread wheat: bread making properties vary but are usually lower than bread wheat. Missing some gliadin proteins. | Usually has higher minerals, higher fiber and lower glycemic index. | Often has higher antioxidants (total phenolics and flavonoids) and protein. Not high in carotenoids. | Often has higher phytic acid concentration. Emmer | The species is a known source of disease and pest resistance traits (common bunt, stem rust, leaf rust, powdery mildew, Septoria Leaf Blotch, Loose smut, Tan Spot, Russian wheat aphid, Hessian Fly) | Asian and African types appear to be more drought tolerant | Some varieties have shown tolerance to higher soil salinity | Alternate source of dwarfing trait Spelt | Spelt has gluten and similar protein composition to bread wheat but reduced bread making quality. | Higher lipid and unsaturated fatty acid content. | Some minerals tend to be higher in spelt: Fe, Zn, Mg, P.

  • Ancient Grains for Today's Tastes
    Ancient Grains for Today’s Tastes You may have heard the term “ancient grains” and wondered just which grains are considered ancient. Though there’s no strict list of grains that qualify, generally the term refers to grains that have come down to us largely unchanged over centuries. Examples might include quinoa, amaranth, millet, teff, and wild rice, along with wheat varieties such as einkorn, emmer (farro), spelt and khorasan wheat (Kamut®). There are three good reasons to eat ancient grains: 1. Good Taste. Each different grain has its own particular taste and texture. When you change it up, you’ll discover new flavors that could become longtime favorites. Life is too short to eat the same thing day after day! 2. Better Health. If your doctor asked you to eat more vegetables, you wouldn’t simply eat carrots (as healthy as they are!) – you would realize intuitively that different vegetables offer different nutrients your body needs. Same with grains. When you bring more diversity to your grain choices, your body gets a wider range of important nutrients. Recent research, for instance, shows that Kamut® (right) has higher levels of certain minerals and antioxidants than modern wheat and increased ability to combat infection; black and red rice are also higher in antioxidants than brown rice. 3. Great Stories. Eating food with a story behind it connects us to life on earth in meaningful ways. This is of course true when you “eat local” and connect with growers at your farmers market. It’s also true when your food comes from far away but arrives with a story.

Three years of field experiments were carried out from 2015 to 2017 in the Lubelskie province (Poland) on rendzina soils. The experimental results indicate that the hulled wheats, even when cultivated with advanced technology, produced lower yields compared to the common and durum wheats (reduced by 30–56%). In spite of their lower yields, emmer and spelt retained appropriate technological parameters. Higher ash, protein, and wet gluten yields were characteristic of the hulled wheats; however, the high gluten spread of emmer (13.3 mm) may limit its application as a raw material in some food processes. In summary, hulled wheat species can be recommended for modern agricultural production as an alternative source of high-quality materials for the agricultural and food industries.

INTRODUCTION Crop plants are our greatest heritage from prehistory (Harlan 1992; Diamond 2002). How, where, and when the domestication of crops plants occurred is slowly becoming revealed although not completely understood (Camp et al. 1957; Smartt and Simmonds 1995; Gepts 2003). In some cases, the genetic distance between wild and domestic plants is so great, maize and crucifers, for example, that their origins are obscure. The origins of the ancient grains (wheat, maize, rice, and sorghum) and pulses (sesame and lentil) domesticated in Neolithic times have been the subject of intense interest and the puzzle is being solved with the new evidence based on molecular biology (Gepts 2003).
