Identification of Cereal Remains from Archaeological Sites 2Nd Edition 2006
Identification of cereal remains from archaeological sites 2nd edition 2006 Spikelet fork of the “new glume wheat” (Jones et al. 2000) Stefanie JACOMET and collaborators Archaeobotany Lab IPAS, Basel University English translation partly by James Greig CEREALS: CEREALIA Fam. Poaceae /Gramineae (Grasses) Systematics and Taxonomy All cereal species belong botanically (taxonomically) to the large family of the Gramineae (Poaceae). This is one of the largest Angiosperm families with >10 000 different species. In the following the systematics for some of the most imporant taxa is shown: class: Monocotyledoneae order: Poales familiy: Poaceae (= Gramineae) (Süssgräser) subfamily: Pooideae Tribus: Triticeae Subtribus: Triticinae genera: Triticum (Weizen, wheat); Aegilops ; Hordeum (Gerste; barley); Elymus; Hordelymus; Agropyron; Secale (Roggen, rye) Note : Avena and the millets belong to other Tribus. The identification of prehistoric cereal remains assumes understanding of different subject areas in botany. These are mainly morphology and anatomy, but also phylogeny and evolution (and today, also genetics). Since most of the cereal species are treated as domesticated plants, many different forms such as subspecies, varieties, and forms appear inside the genus and species (see table below). In domesticates the taxonomical category of variety is also called “sort” (lat. cultivar, abbreviated: cv.). This refers to a variety which evolved through breeding. Cultivar is the lowest taxonomic rank in the domesticated plants. Occasionally, cultivars are also called races: e.g. landraces evolved through genetic isolation, under local environmental conditions whereas „high-breed-races“ were breed by strong selection of humans. Anyhow: The morphological delimitation of cultivars is difficult, sometimes even impossible. It needs great experience and very detailed morphological knowledge. -
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. -

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. -
Black Chaff of Wheat Stephen N
® ® University of Nebraska–Lincoln Extension, Institute of Agriculture and Natural Resources Know how. Know now. G1672 (Revised December 2012) Black Chaff of Wheat Stephen N. Wegulo, Extension Plant Pathologist widely distributed bacterial disease of small grains and can Cause, symptoms, disease cycle, and management cause yield losses of up to 40 percent. of black chaff of wheat. Cause and Symptoms Black chaff is a bacterial disease of wheat common in Black chaff is caused by the bacterium Xanthomonas irrigated fields or in areas with abundant rainfall during the campestris pathovar (pv.) undulosa. The disease derives its growing season. It is also known as bacterial stripe or bacte- name from the darkened glumes of infected plants (Figure rial leaf streak. The disease also occurs on barley, oats, rye, 1A). This symptom is similar to that caused by genetic triticale, and many grasses. It is the most important and most melanism (darkening of tissue) and glume blotch incited by Stagonospora nodorum. Black chaff can be distinguished from other diseases by the appearance of cream to yellow bacterial ooze in the form of slime or viscous droplets produced on infected plant parts during wet or humid weather. This ooze appears light colored and scale-like when dry. Bands of necrotic and healthy tissue on awns (“barber’s pole” appearance) are indicative of black chaff. A dark brown to purple discoloration may appear on the stem below the head and above the flag leaf (Figure 1B). On leaves, symptoms start as small water-soaked spots or streaks that turn brown after a few days. -

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 Cleaning Basics
Goal in Wheat Cleaning • Remove Non-Wheat Material – Metal – Foreign Material (Debris) – Stones – Grains other than wheat (soybean, corn, sorghum,… etc. – Weed Seeds • Remove Wheat not-fit for Milling – Shrunken & Broken – Diseased & Damaged Non-Wheat Material Wheat not-fit for Milling Shrunken/Shriveled Diseased- Scab Insect Damaged Black Tip (color defect) Ergot Heat Damaged Physical Properties of Common Impurities • Impurities are separated from wheat based physical differences which aid their removal. • Magnetic properties • Flow in air properties • Size and shape • Density • Friability (easily broken by impact) • Surface characteristics (color and texture) Wheat Cleaning System Cleaning System Design Principle 1. Eliminate impurities that pose a significant health and safety risk first. – Ferrous Metal (grain dust explosion hazard). – Grain Dust (explosion risk, health/safety risk). 2. Eliminate impurities which impact downstream machine efficiency. – Light chaff and dust (bulky, poor flow characteristics, decreases screening efficiency). Generic Cleaning Flow Principle Magnetic Separation Dust/chaff removal Size- coarse tolerance Larger/Smaller Size- fine tolerance Density Length Width Shape Friction/Abrasion Impact Friability Color/ Surface Characteristics Pre-Cleaning for Wheat Storage Benefits of Pre-Cleaning • Decrease infestation risk. • Improve sanitation and dust control. • Decrease microbial growth. • Improves flow of grain through the bin. • Increases storage life of grain. Generic Cleaning Flow Principle Grain Dust Explosion Risk. Magnetic Separation Explosion risk, sanitation, health and safety risk. Dust/chaff Removal Greatly improves equipment efficiency. Least similar to wheat based on size. Easy to remove. Larger/Smaller than wheat Reduces bulk. Lighter than wheat. Stones and mud removal. Density High and low density separation.

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. -
ELP and ESP Station Handout Grist Mill
ELP and ESP Station Handout Grist Mill INTRODUCTION The goal of this handout is to prepare you to lead the Grist Mill station during your Environmental Living Program or Environmental Studies Program. At the Grist Mill station, your students will experience firsthand what it was like to grind wheat into flour using a hand- powered grist mill. This station will allow you and your students to explore the history, science, language, and math related to agriculture. HISTORY The Fort’s primary crop was wheat and there were a number of fields near the Fort, so the grist mill had an important place at Sutter’s Fort. The mill was likely in operation both day and night, and prior to the establishment of the Fort, the nearest grist mill was about 65 miles away in Sonoma. It was not until 1846, when a grist mill was opened, near present day Sloughhouse, that there was another local source for flour. The mill and agriculture were central to John Sutter’s business plan for the Fort. He hoped create a thriving agricultural business. However, to be successful in agriculture, Sutter needed countless laborers. The large majority of those laborers were local California Indians. Early visitors to the Fort, such as the French diplomat and dignitary Comte de Mofras, wrote glowingly about the limitless potential for agriculture at New Helvetia. The rich soil and the flat grasslands were an agricultural paradise to the trained eye. However, potential does not always translate into production; Sutter and the large California Indian workforce had many obstacles to overcome. -
Hulled Wheat Productivity and Quality in Modern Agriculture Against Conventional Wheat Species

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. -
