enzymatic browning and formation of brown pigments are some of the most important problems in preparation of mushroom purees. in this study, the effect of some anti browning agents including sodium metabisulphite, ascorbic acid, and citric acid on the whiteness and foaming properties of mushroom purees was investigated. the results showed that soaking with acids and sodium metabisulphite signif...

Glass foam tablets were produced from container glass bottles (CGB) using eggshell waste (ESW) and perlite (P) as foaming agent in different portions. The ground raw materials (CGB, ESW, P) homogenized pressed with hydraulic piston press machine at pressures (in the case of P containing 30 MPa ESW 15 MPa, 40 used).The obtained heat treated temperatures 800 °C, 900°C, 1000°C 1100°C, 600 700 °C 9...

Due to the high viscosity and stickiness of dehydrated sludge, combination foaming pretreatment drying process is an effective method improve performance sludge. In this study, alkali industrial lignin fiber addition followed by mechanical whipping was employed for dewatered Using alone as agent, optimal NaOH found at 2.5 wt%, which superior adding CaO. Considering maximum efficiency, 2% FH-300...

Thermal insulation gypsum plaster was prepared from flue gas desulphurization (FGD) gypsum. K12 is more recommendable as foaming agent, when the mass fraction of K12 is around 0.1 %, the setting time and compressive strength meet the requirements of gypsum-based construction materials. In the meanwhile, the thermal conductivity is 0.18 W m−1 K−1, which can be used as a thermal insulation materi...

A high mechanical strength glass-ceramic foam was produced by direct microwave heating at 853 ºC of a very weight ratio coal fly ash (82%), calcium carbonate (5%) as foaming agent, sodium (13%) fluxing agent and water addition (10%). Due to the excellent energy efficiency heating, rate had value (32 ºC/min), much higher than conventional processes led low specific consumption (0.72 kWh/kg). The...

Traditional LCA of central plant hot recycling shows that, the higher RAP added, the less energy consumed. This conclusion is mainly based on the calculation of reduced raw material. However, when the content of Reclaimed asphalt pavement mixture (RAP) reaches some level, it is needed to take measures such as using additive or improved construction method for maintain the performance of asphalt...
