Identification of Characterizing Aroma Components of Roasted Chicory
Article Cite This: J. Agric. Food Chem. XXXX, XXX, XXX−XXX pubs.acs.org/JAFC Identification of Characterizing Aroma Components of Roasted Chicory “Coffee” Brews Tiandan Wu and Keith R. Cadwallader* Department of Food Science and Human Nutrition, University of Illinois at Urbana−Champaign, 1302 West Pennsylvania Avenue, Urbana, Illinois 61801, United States *S Supporting Information ABSTRACT: The roasted and ground root of the chicory plant (Cichorium intybus), often referred to as chicory coffee, has served as a coffee surrogate for well over 2 centuries and is still in common use today. Volatile components of roasted chicory brews were identified by direct solvent extraction and solvent-assisted flavor evaporation (SAFE) combined with gas chromatography−olfactometry (GC−O), aroma extract dilution analysis (AEDA), and gas chromatography−mass spectrometry (GC−MS). A total of 46 compounds were quantitated by stable isotope dilution analysis (SIDA) and internal standard methods, and odor-activity values (OAVs) were calculated. On the basis of the combined results of AEDA and OAVs, rotundone was considered to be the most potent odorant in roasted chicory. On the basis of their high OAVs, additional predominant odorants included 3-hydroxy-4,5-dimethyl-2(5H)-furanone (sotolon), 2-methylpropanal, 3-methylbutanal, 2,3- dihydro-5-hydroxy-6-methyl-4H-pyran-4-one (dihydromaltol), 1-octen-3-one, 2-ethyl-3,5-dimethylpyrazine, 4-hydroxy-2,5- dimethyl-3(2H)-furanone (HDMF), and 3-hydroxy-2-methyl-4-pyrone (maltol). Rotundone, with its distinctive aromatic woody, peppery, and “chicory-like” note was also detected in five different commercial ground roasted chicory products. -

Pest and Diseases in Mango (Mangifera Indica L.) J
PEST AND DISEASES IN MANGO (MANGIFERA INDICA L.) J. González-Fernández, J.I. Hormaza IHSM la Mayora CSIC-UMA, 29750 Algarrobo, Malaga, Spain EXECUTIVE SUMMARY In this work, we review the most important pests and diseases that affect mango production worldwide as well as the main measures implemented to control them. Pests and diseases are the main factors that can impact sustainable mango fruit production in the tropics and subtropics worldwide. Commercial cultivation of mango, characterized by expansion to new areas, changing crop management, replacement of varieties and increased chemical interventions, has altered significantly the pest and disease community structure in this crop in the different mango producing regions. In addition, climate change is inducing the emergence of new pests and, whereas globalization and trade liberalization have created wide opportunities for mango commercialization growth, at the same time, this can result in faster dispersion of pests and diseases among different mango growing areas if proper sanitary measures are not implemented. This review covers different topics related to pests and diseases in mango. First, a thorough description of the main pests and diseases that affect mango is provided. Second, the different approaches used in different mango producing countries for chemical and biological control are described. Third, recommendations for appropriate mango management techiques that include integrated pest and disease management, reduction in the use of chemicals and the implementation of a good monitoring and surveillance system to help control the main pests and diseases, are also discussed. Finally, the current knowledge on agrohomeopathy and Korean Natural Farming is analyzed and recommendations on future lines of research to optimize mango pest and disease control are discussed. -
Wild-Harvested Edible Insects

Oral Presentations
ORAL PRESENTATIONS Listed in programme order Technical analysis of archaeological Andean painted textiles Rebecca Summerour1*, Jennifer Giaccai2, Keats Webb3, Chika Mori2, Nicole Little3 1National Museum of the American Indian, Smithsonian Institution (NMAI) 2Freer Gallery of Art and Arthur M. Sackler Gallery, Smithsonian Institution (FSG) 3Museum Conservation Institute, Smithsonian Institution (MCI) 1*[email protected] This project investigates materials and manufacturing techniques used to create twenty-one archaeological painted Andean textiles in the collection of the National Museum of the American Indian, Smithsonian Institution (NMAI). The textiles are attributed to Peru but have minimal provenience. Research and consultations with Andean textile scholars helped identify the cultural attributions for most of the textiles as Chancay and Chimu Capac or Ancón. Characterization of the colorants in these textiles is revealing previously undocumented materials and artistic processes used by ancient Andean textile artists. The project is conducted as part of an Andrew W. Mellon Postgraduate Fellowship in Textile Conservation at the NMAI. The textiles in the study are plain-woven cotton fabrics with colorants applied to one side. The colorants, which include pinks, reds, oranges, browns, blues, and black, appear to be paints that were applied in a paste form, distinguishing them from immersion dyes. The paints are embedded in the fibers on one side of the fabrics and most appear matte, suggesting they contain minimal or no binder. Some of the brown colors, most prominent as outlines in the Chancay-style fragments, appear thick and shiny in some areas. It is possible that these lines are a resist material used to prevent colorants from bleeding into adjacent design elements. -
State-Of-The-Art on Use of Insects As Animal Feed
State-of-the-art on use of insects as animal feed Harinder P.S. Makkar1, Gilles Tran2, Valérie Heuzé2 and Philippe Ankers1 1 Animal Production and Health Division, FAO, Rome 2 Association Française de Zootechnie, Paris, France Full reference of the paper: Animal Feed Science and Technology, Volume 197, November 2014, pages 1-33 Link: http://www.animalfeedscience.com/article/S0377-8401(14)00232-6/abstract http://dx.doi.org/10.1016/j.anifeedsci.2014.07.008 Abstract A 60-70% increase in consumption of animal products is expected by 2050. This increase in the consumption will demand enormous resources, the feed being the most challenging because of the limited availability of natural resources, ongoing climatic changes and food-feed-fuel competition. The costs of conventional feed resources such as soymeal and fishmeal are very high and moreover their availability in the future will be limited. Insect rearing could be a part of the solutions. Although some studies have been conducted on evaluation of insects, insect larvae or insect meals as an ingredient in the diets of some animal species, this field is in infancy. Here we collate, synthesize and discuss the available information on five major insect species studied with respect to evaluation of their products as animal feed. The nutritional quality of black soldier fly larvae, the house fly maggots, mealworm, locusts- grasshoppers-crickets, and silkworm meal and their use as a replacement of soymeal and fishmeal in the diets of poultry, pigs, fish species and ruminants are discussed. The crude protein contents of these alternate resources are high: 42 to 63% and so are the lipid contents (up to 36% oil), which could possibly be extracted and used for various applications including biodiesel production. -

(BZC & MZC Entomology Students) Sericulture Farm. Shadnagar
ZOOLOGY FIELD TRIPS: B.Sc (BZC & MZC Entomology students) Sericulture Farm. Shadnagar (17 Sep 2019) The Department of Zoology has a study trip for the Students of B.Sc (BZC / MZC) final year (Entomology) to the Sericulture farm in Shadnagar. We have Visited Three Centers: 1. State Horticulture and Sericulture Office – a Government Institution located in Lingojiguda, Shadnagar under the supervision of Mrs. Nagaratna, disrict sericulture officer. 2. A private farm – where the larvae are reared from eggs to Pupal stage using Mulberry leaves. 3. A Forest area – where Mulberry plantation and Nursery is located. In the First place, the reeling of the Silk Cocoons is done. They purchase Cocoons from the private farm. The Cocoons are then separated based on the quality. The Finest quality of silk is produced from healthy cocoons. Each Cocoon produces 1200 meters of silk. Silk produced from 6 cocoons, is woven as one thread which is very soft & delicate, this is used in fine Kashmiri silk sarees. It weighs very less & the Silk is very soft. In some cases 12-15 cocoons are used which gives a rough texture to silk. The Second quality Cross breed cocoons are yellow in color which is usually mixed with other threads. The Third type is Double cocoons which produce Dupian silk. When unhealthy larvae form cocoons, flimsy silk is produced. In the next step, the larvae are killed inside the Cocoon by keeping them in ovens. The dead cocoons are stored in large trays in big racks in a room. The trays are numbered & dated. Everyday few cocoons are taken for reeling. -

Wax, Wings, and Swarms: Insects and Their Products As Art Media
Wax, Wings, and Swarms: Insects and their Products as Art Media Barrett Anthony Klein Pupating Lab Biology Department, University of Wisconsin—La Crosse, La Crosse, WI 54601 email: [email protected] When citing this paper, please use the following: Klein BA. Submitted. Wax, Wings, and Swarms: Insects and their Products as Art Media. Annu. Rev. Entom. DOI: 10.1146/annurev-ento-020821-060803 Keywords art, cochineal, cultural entomology, ethnoentomology, insect media art, silk 1 Abstract Every facet of human culture is in some way affected by our abundant, diverse insect neighbors. Our relationship with insects has been on display throughout the history of art, sometimes explicitly, but frequently in inconspicuous ways. This is because artists can depict insects overtly, but they can also allude to insects conceptually, or use insect products in a purely utilitarian manner. Insects themselves can serve as art media, and artists have explored or exploited insects for their products (silk, wax, honey, propolis, carmine, shellac, nest paper), body parts (e.g., wings), and whole bodies (dead, alive, individually, or as collectives). This review surveys insects and their products used as media in the visual arts, and considers the untapped potential for artistic exploration of media derived from insects. The history, value, and ethics of “insect media art” are topics relevant at a time when the natural world is at unprecedented risk. INTRODUCTION The value of studying cultural entomology and insect art No review of human culture would be complete without art, and no review of art would be complete without the inclusion of insects. Cultural entomology, a field of study formalized in 1980 (43), and ambitiously reviewed 35 years ago by Charles Hogue (44), clearly illustrates that artists have an inordinate fondness for insects.
