摘要:Synthesis Of C8-Prenylated Flavonols And Flavanones Via The Palladium-Catalyzed 7-O-1,1-Dimethylprop-2-Enylation,Followed By Claisen Rearrangement Is Described. Two Regioselectivities (Carbon-Carbon Bond Formation At Either The Tail Or Head Of The Prenyl Group And Carbon-Carbon Bond Formation At Either C8 Or C6) Were Efficiently Improved When Acetic Anhydride Was Used As A Solvent Instead Of N,N-Dimethylformamide.

摘要:A trub, hops and yeast mix (THYM), a problematic brewery side stream, has high amounts of antimicrobial hop metabolites and positive nutritional effects. Trub, hops and yeast wastes from fermenters, whirlpools, mash tuns, kettles, hopbacks, and grundies with pumps, sanitary piping and storage tanks are combined. Dewatering the mix caused an unexpected improvement in the stability and rheological properties of the THYM, allowing for greater material handling. Dewatering and drying may be by using one or more of filter bags, double drum dryers, rotary dryers, agitated mixing, and flash dryers. A dry product is produced which is suitable for pelletizing and/or packaging. THYM as a feed or supplement can improve weight gain in animals, enhance food flavors, stimulate rumen propionate synthesis, reduce methane production in vitro, increase bovine feed efficiency in vivo, positively alter the gut microbiome.
