Characterization of zein extracted from beer solids, a coproduct of dry-grind ethanol
… as a possible new application. The effect of extraction conditions: ethanol content of the solvent (55, 70 and 90% ethanol), pH, processing temperature and time, on zein quality and functionality parameters was evaluated. NaOH was used to modify the pH of extraction solvent. Alkaline …

Digestion of inositol phosphates by dairy cows: Method development and application
… Clean-up procedures were developed for acid and alkaline extracts of feed, ruminant digesta and feces and clarified extracts were analyzed for Pp using high performance ion chromatography (HPIC). The quantified Pp in acid and alkaline extracts was comparable for feed but alkaline extraction …

Polonium extraction techniques for a lead-bismuth cooled fast reactor
… inhibited proper sample analysis. The extraction techniques of rare-earth filtering and polonium hydride stripping and their relative figures of merit were discussed. Of the two techniques, a small-scale design adopting polonium hydride stripping was explored to address basic issues of …

Comparison of Extraction Techniques for Δ-9-Tetrahydrocannabinol from Urine
… procedures. In past research, either a strong alkaline solution or β-glucuronidase has been used to cleave the bond between the Δ-9-THC and glucuronic acid before an alkaline extraction. Δ-9-THC has a pKa of 10.6 and therefore is always extracted at an alkaline pH. In this study, both a strong …

Peroxyalkanoic cellulose purification of steam exploded yellow poplar
… bleaching was achieved through treatment with alkaline peroxide in several stages. Performic acid experiments were performed by researchers at the Finnish Pulp and Paper Research Institute: K. Poppius, I. Tuominen and J. Sundquist. Peracetic experiments were conducted at Virginia Tech. The …

Isolation and partial characterization of host cell wall surface glycoproteins: their involvement in agglutination, attachment and appressorium formation by piptocephalis virginiana
Cell surface proteins obtained by alkaline extraction from isolated cell walls of Mortierella pusilla and M. candelabrum, host and nonhost, respectively, to the mycoparasite, Piptocephalis virginiana, were tested for their ability to agglutinate mycoparasite spores. The host cell wall protein …

Production of Selenium-enriched Wheat Protein Concentrates and Isolates for Enhancement of Wheat Flour Functionality
… and dry processing (grinding, aqueous & aqueous-alkaline) extraction schemes yielded wheat fractions with predictable Se content from ground whole wheat. Grain with 3.5, 5.2, and 10.3 ppm Se yielded WPC with Se concentrations of 16.8, 22.6 and 46.1 ppm and WPI of 15.8, 21.2 and 43.8 ppm, …

Rapid Phytate Quantification in Manures and Runoff Sediments using HPIC
… spiked with Al, Fe, and phytate. Samples were alkaline extracted, acidified,cleaned up and filtered, and then phytate was analyzed with HPIC. High concentrations of Fe did not hinder phytate recovery in manure or litter samples. While phytate recovery was close to 100% at typical manure and …

Color and Structural Modifications of Alkaline Extracted Sunflower Protein Concentrates and Isolates Using L-Cysteine and Glutathione
<p>Sunflower protein can be extracted at alkaline pH with sulfites or organic solvent de-phenolization of sunflower seed meals if greening is unwanted. This greening is promoted at alkaline pH when chlorogenic acid (CGA) oxidizes and reacts with free amine groups from amino acids, such as lysine. …

Downstream processing of Black soldier fly larvae protein for human consumption
… the considerable lipid fraction in BSFL. Aqueous extraction (e.g. the two-stage alkaline extraction process developed in earlier work) can separate BSFL protein from chitin and lipids, but also co-extracts pigments and off-odours, producing dark-brown powders with reduced sensory and aesthetic …
