Researching the special and infraspecial structure in causative agent populations of the most dangerous diseases root rots of cereals in various regions of the Russjan Federation has been carried ...out. The defeat of cereals root rots old in Russia causes in the a complex patogenic. More often meet Fusarium culmorum (W.G.Sm.) Sacc., F. oxysporum (Schlecht.)

A large assemblage of charred cereal grains was found at the multicultural site Kraków Nowa Huta – Mogiła 62 during a rescue excavations performed in the late 1960s. It provided valuable source of ...material for archaeobotanical and stable isotope studies. Both current botanical analyses of six subsamples and new radiocarbon dates of the top and the bottom of the layer indicated their Middle Neolithic origin (the Funnel Beaker culture). Despite the earlier suspicion that the material was disturbed by the construction work, the field documentation stored in the Archaeological Museum and the new archaeobotanical analyses indicate that the layer with the cereal grains, which was found at the depth of 300–330 cm was in fact, undisturbed. The cereals (mostly emmer with admixture of einkorn) were stored in a form of spikelets (as indicated by proportions of chaff and grains) and the assemblage was a final product of harvest cleaning (as suggested by low number of arable weeds). Values of stable carbon and nitrogen ratios suggest that the storage contained cereals originated from plots of different level of manuring and similar soil moisture, however more isotopic measurements are necessary to confirm that hypothesis. It is also supported by different proportions of taxa in the studied subsamples. Most of the emmer grains were sprouted before charring. We assume the grain was spoilt by excessive humidity of the storage conditions.
The contamination of food products by mycotoxin particularly trichothecenes is a serious health concern. While several studies investigated the concentration and prevalence of trichothecenes in ...cereal-based products, a comprehensive meta-analysis is not available.
The concentration and prevalence of trichothecenes (TCNs) such as deoxynivalenol (DON), nivalenol (NIV), 3-acetyldeoxynivalen, 15-acetyldeoxynivalen, toxins T-2 and HT-2, neosolaniol (NEO), fusarenon-X and 4,15-diacetoxyscirpe in cereal-based food products among databases including Scopus, Web of Science, PubMed and Embase was investigated between 1 January of 1983 and 1 February of 2019 by the aid of a systematic review and meta-analysis prevalence. Among 950 explored articles in the identification stage, 57 articles with 372 samples were included in the current meta-analysis.
Among all studied TCNs, the concentration of DON in cereal-based products were higher than others, exceptionally in bread samples which fusurenon x was the dominant TCNs. Also, the highest TCNs prevalence was correlated with DON, except for baby and infant foods which had predominantly T-2. The overall rank order based on the concentration and prevalence of TCNs were breakfast cereals > noddle > bread > wheat foods > pasta > infant foods > barley prevalence and prevalence barley > wheat foods > infant foods > pasta > bread > breakfast cereals > noddle, respectively. The outcomes of the present meta-analysis highlighted the demand for further improvements in controlling of TCNs among cereal-based products, besides approaching mitigation techniques in order to reduce the dietary exposure to TCNs via the consumption of cereal-based foods.

Summary
Millets are sustainable drought‐resistant crops capable of surviving a wide range of climatic conditions. They are small‐seeded grains rich in proteins, minerals and bioactive compounds ...inducing several health benefits and provide protection against chronic and degenerative modern lifestyle disorders. Hypoglycaemic profile and bioactive composition are the key elements for the popularity of millets as functional ingredients for the development of novel food products of commercial importance. Despite numerous health benefits and agro‐economic potential, millets have lost their popularity due to coarse nature and are underutilised in developed countries. Food scientists and nutritionists are characterising and valorising millets to enhance their use for food applications. The present article reviews research investigations about nutritional composition (macro‐ and micro‐nutrients), biologically active components (phenolic acid, flavonoids, phytosterols and related antioxidant potential) and techno‐functionality of millets. Pharmacological impact and their utilisation in value‐added products have also been included.
Millets: Functionality, Bioactivity and Health Benefits.
Reliable tables of glycemic indexes (GIs) and glycemic loads (GLs) are critical to research examining the relationship between glycemic qualities of carbohydrate in foods, diets, and health. In the ...12 years since the last edition of the tables, a large amount of new data has become available.
To systematically review and tabulate published and unpublished sources of reliable GI values, including an assessment of the reliability of the data.
This edition of the tables lists over 4000 items, a 61% increase in the number of entries compared to the 2008 edition. The data have been separated into 2 lists. The first represents more precise values derived using the methodology recommended by the International Standards Organization (∼2100 items). The second list contains values determined using less robust methods, including using limited numbers of healthy subjects or with a large SEM (∼1900 food items).
Dairy products, legumes, pasta, and fruits were usually low-GI foods (≤55 on the 100-point glucose scale) and had consistent values around the world. Cereals and cereal products, however, including whole-grain or whole-meal versions, showed wide variation in GI values, presumably arising from variations in manufacturing methods. Breads, breakfast cereals, rice, savory snack products, and regional foods were available in high-, medium-, and low-GI versions. Most varieties of potato were high-GI foods, but specific low-GI varieties have now been identified.
The availability of new data on the GIs of foods will facilitate wider research and application of the twin concepts of GI and GL. Although the 2021 edition of the tables improves the quality and quantity of GI data available for research and clinical practice, GI testing of regional foods remains a priority. This systematic review was registered in PROSPERO as #171204.

Sprouting induces activation and de novo synthesis of hydrolytic enzymes that make nutrients available for plant growth and development. Consumption of sprouted grains is suggested to be beneficial ...for human health. Positive consumer perceptions about sprouted cereals have resulted in new food and beverage product launches. However, because there is no generally accepted definition of “sprouting,” it is unclear when grains are to be called sprouted. Moreover, guidelines about how much sprouted grain material food products should contain to exert health benefits are currently lacking. Accordingly, there is no regulatory base to develop appropriate food labeling for “sprouted foods.” This review describes the nutritional and technological properties of sprouted grains in relation to processing conditions and provides guidelines to optimize sprouting practices in order to maximize nutritive value. Relatively long sprouting times (3 to 5 days) and/or high processing temperatures (25 to 35 °C) are needed to maximize the de novo synthesis and/or release of plant bioactive compounds. Nutrient compositional changes resulting from sprouting are often associated with health benefits. However, supportive data from clinical studies are very scarce, and at present it is impossible to draw any conclusion on health benefits of sprouted cereals. Finally, grains sprouted under the above‐mentioned conditions are generally unfit for use in traditional food processing and it is challenging to use sprouted grains as ingredients without compromising their nutrient content. The present review provides a basis for better defining what “sprouting” is, and to help further research and development efforts in this field as well as future food regulations development.
