Spent yeasts are by-products arising from beer and wine production which over many years have been chiefly used as feed additives for livestock. They contain many valuable and bioactive substances which has thereby generated much interest in their exploitation. Up till now, the main products obtained from beer-brewing yeasts are β-glucans and yeast extracts. Other like foodstuffs include dried brewer’s yeast, where this is dried and the bitterness removed to be fit for human consumption as well as mannan-oligosaccharides hitherto used in the feed industry...

Aflatoxin B1 (AFB1 ) is one of the most commonly found mycotoxins in food commodities, particularly cereals, oilseeds, spices and tree nuts. In the past decade, aptamers have come into limelight and emerged as a new biosensing element replacing antibodies in various detection formats. Herein we report a faster, more sensitive, high throughput method for the detection of AFB1 using AFB1 -specific aptamers. The assay format was based on a competitive reaction of the fluorescent tagged aptamer specific to AFB1 with the aflatoxin conjugate...

Fast detection of heavy metals in plant materials is crucial for environmental remediation and ensuring food safety. However, most plant materials contain high moisture content, the influence of which cannot be simply ignored. Hence, we proposed moisture influence reducing method for fast detection of heavy metals using laser-induced breakdown spectroscopy (LIBS). Firstly, we investigated the effect of moisture content on signal intensity, stability and plasma parameters (temperature and electron density), and determined main influence factors (experimental parameters F and the change of analyte concentration...

The proportions of woody and grassland taxa in terrestrial ecosystems played an important role in the origin and evolution of early Palaeolithic hominins. However the influence of ecosystem changes on hominin behavior and adaptations in Asia has not been studied in detail. Hominins have exploited the Luonan Basin in the Eastern Qinling Mountains, central China, since the early Paleolithic. Dated sites, consisting of alternating loess and soil deposits with in situ artefacts, are common in the region, and provide a detailed record of Early to Middle Pleistocene hominin environments...

Amphora sp. was isolated from the Sfax Solar Saltern and cultivated under hypersaline conditions. It contains moderate rates of proteins, lipids, sugars, and minerals and a prominent content of bioactive compounds: polyphenols, chlorophyll a, carotenoids, and fatty acids. The analysis of fatty acids with GC/MS showed that the C16 series accounted for about 75% of Amphora sp. lipids. Saturated fatty acids whose palmitic acid was the most important (27.41%) represented 41.31%. Amphora sp. was found to be rich in monounsaturated fatty acids with dominance of palmitoleic acid...

The subfamily Carpophilinae, in particular the genus Carpophilus Stephens, represents one of the most speciose lineages within Nitidulidae. The subfamily is comprised of more than 250 described species that are found worldwide in every habitable region, and have been transported by man in stored products to remote islands and archipelagos (Ewing & Cline 2005; Parsons 1943). The ubiquitous Carpophilus dimidiatus (L.) is an example of a cosmopolitan species that has been reported from every continent except Antarctica, but likely has been transported there as well...

The stability of mulberry-extracted anthocyanin is a main concern in food supplement application. In this article, the alginate/chitosan beads were fabricated by spray drying and external gelation techniques using different processes: (1) dropping a sodium alginate solution into a CaCl2 solution containing chitosan and (2) incubating calcium alginate beads in a solution of chitosan. These beads were introduced as microcarrier to enhance the stability and bioavailability of anthocyanin. We showed that the beads fabricated by different processes could encapsulate the anthocyanin at different amounts...

Optimal fluid resuscitation on the battlefield in the absence of blood products remains unclear. Contemporary Combat medics are generally limited to hydroxyethyl starch or crystalloid solutions, both of which present significant drawbacks. Obtaining US Food and Drug Administration (FDA)-approved freeze-dried plasma (FDP) is a top casualty care research priority for the US Military. Interest in this agent reflects a desire to simultaneously expand intravascular volume and address coagulopathy. The history of FDP dates to the Second World War, when American expeditionary forces used this agent frequently...

Ankit Kumar, Carlo Montemagno, Hyo-Jick Choi
The development of a smart microencapsulation system programmed to actively respond to environmental pH change has long been recognized a key technology in pharmaceutical and food sciences. To this end, we developed hollow microparticles (MPs) with self-controlled macropores that respond to environmental pH change, using an Oil-in-Water emulsion technique, for oral drug delivery. We observed that freeze-drying of MPs induced closure of macropores. The closing/opening behavior of macropores was confirmed by exposing MPs encapsulating different ingredients (sulforhodamine b, fluorescent nanoparticles, and lactase) to simulated gastrointestinal (GI) fluids...

Wheat is one of the major staple food of the world, which is badly affected by water deficit stress. To fulfill the dietary needs of increasing population with depleting water resources there is need to adopt technologies which result in sufficient crop yield with less water consumption. One of them is partial root zone drying (PRD). Keeping in view these conditions, a wire house experiment was conducted at University College of Agriculture and Environmental Sciences, The Islamia University Bahawalpur during 2015, to screen out the different wheat genotypes for PRD...
