Importer Preferences and Opinions on Vacuum and Steam Treatment Technology for Hardwood Logs Export
… on the logs imported, of which chemical treatment is common. This study examines the feasibility and implications of transitioning from chemical-based treatments, such as methyl bromide, to a vacuum and steam treatment for hardwood log exports. Our investigation focuses on understanding …

The effect of steam treatment and precipitation hardening on the mechanical properties and wear resistance of sintered iron and iron-copper alloys
Steam treatments reduce porosity(1) of sintered iron and sintered iron-base alloy products and provide them with increased compressive strength, hardness, resistance to wear and corrosion. The aims of the present investigation were: (a) to examine the influence of copper content and process …

Fractional Catalytic Pyrolysis Technology for the Production of Upgraded Bio-oil using FCC Catalyst
… poplar wood. The influence of Y-zeolite content, steam treatment, addition of ZSM-5 additive, process conditions (temperature, weight hourly space velocity (WHSV) and vapor residence time) and recycling of the non-condensable gases (NCG) on the product distribution and the quality of the bio-oil …

Effects of Bran Content, Thermal Treatment, and Storage on Flavor Development and Functionality in Intermediate Wheatgrass Flour
… IWG flour have not yet been addressed. Thermal treatment may be used to increase grain shelf life by inactivating enzymes that are involved in lipid rancidity, which is a major pathway for the formation of odor active volatile odor active compounds (VOAC). On the other hand, thermal treatment …

Mechanical behavior of red oak in transverse compression as affected by hydro-treatments and its relations to changes in cell wall structure and composition
Influence of steam-treatment upon properties, structure, and composition of red oak was investigated. Small specimens of red oak heartwood were submitted to steam-treatments at atmospheric pressure for 1.5, 3, 6, 12, 24, 48, and 96 hours. Short steaming induced little or no changes in the …

Application of Far Infrared Radiation and Ethanol Vapor as Alternative Treatment Methods for Reduction of Salmonella enterica Tennessee in Dried, Ground Spices
… prompting development of additional inactivation treatments that reduce bacterial pathogens while maintaining spice quality. Spices are currently treated by fumigation with ethylene oxide, pasteurization with ionizing radiation, or steam treatment. However, these treatments exhibit flaws …

Protein preservation and rumen degradability of ensiled forage, previously treated with microwave or steam heat, formic acid, or anhydrous ammonia
… objectives of this study were to determine if treatment of forage with heat can reduce proteolysis during subsequent fermentation. In Experiment 1, direct-cut barley and alfalfa were either microwaved or steamed then ensiled in laboratory silos as were untreated and wilted forage. Silages of …

The Elimination of Listeria monocytogenes Biofilms from Stainless Steel Deli Meat Slicer Components by the use of Hurdle Technologies
… also investigated the synergistic effects of steam and chemical sanitizers on disrupting and removing the biofilms formed on the stainless steel coupons. Both flagellated and non-flagellated Listeria strains produced biofilms and there was no correlation observed between the production of …

Desilicated ZSM-5 zeolite as catalyst for the dehydration of ethanol
… zeolites in an aqueous solution of base. This treatment, which decreases the Si/Al ratio while keeping the zeolite framework almost unmodified, enhanced the ion exchange capacities of all the zeolites, a property which can be exploited industrially for the X and Y zeolites since the desilicated …
