Bimetallic Pd-Au/SiO2 Catalysts for Reduction of Furfural in Water

Catalytic systems based on bimetallic Pd-Au particles deposited on SiO2 were prepared by ultrasonically assisted water impregnation and used in the hydrogenation of furfural obtained by the acidic hydrolysis of waste biomass (brewery’s spent grain) in aqueous phase. Pd-Au/SiO2 catalysts containing 50 g of Pd and 2–100 g of Au per 1 kg of catalyst were characterized by high activity in the studied process and, depending on the Pd/Au ratio, selectivity to 2-methyloxolan-2-ol. The modification of 5%Pd/SiO2 by Au leads to the formation of dispersed Au-Pd solid solution phases, which was confirmed by XRD, XPS, ToF-SIMS, SEM-EDS, and H2-TPR techniques. The effect of dilution of surface palladium by gold atoms is probably crucial for modification of the reaction mechanism and formation of 2-methyloxolan-2-ol as the main product.

Brewery’s spent grain is the main by-product of the brewing industry. The effects of replacing fat with arabinoxylan fraction of BSG for physicochemical, textural properties and sensory evaluations of reduced-fat sausages are evaluated. Control was prepared with 15% fat, and three reduced-fat sausages were formulated with 5, 10 and 15% arabinoxylan fraction (T1 sausage with 5% of arabinoxylan fraction + 10% of fat, T2 sausage with 10% of arabinoxylan fraction + 5% of fat and T3 sausage with 15% of arabinoxylan fraction + 0% of fat). With increasing arabinoxylan fraction content in the sausage, the fat content and food calories are decreased in reduced-fat sausages.

Пивоны шаар нь арабиноксиланаар баялаг бөгөөд шүлтийн хандлалтаар гарган авч бүтээгдэхүүнд нэмж туршилтын үр дүнг харьцуулан гаргасан. Зайдасны 4 дээж бэлдсэн. Хяналт (пивоны шаар/арабиноксилан 0%, гахайн өөх 15%), Д1 (пивоны шаар/арабиноксилан 5%, гахайн өөх 10% нэмсэн), Д2 (пивоны шаар/арабиноксилан 10%, гахайн өөх 5%), Д3 (пивоны шаар/арабиноксилан 15%, гахайн өөх 0%). Зайдсанд гахайн өөхийг багасгаж шаараар орлуулснаар тослогийн агууламж, илчлэг чанар буурсан. Түлхүүр үгс: пивоны шаар, арабиноксилан, тослогийн агууламж
