In this study, the production technology of rare-earth oxides from Eskişehir-Beylikova complex ore that contains barite, fluorite, elements, and thorium were investigated. processes can be used in thorium-free mixed rare earth tested. Roasting, leaching, solvent extraction precipitation methods respectively. Roasting temperature roasting duration determined as 600 °C 1 hour, The optimum leachin...

Recently, processed foods have become an important part of human eating habits. However, several processing techniques, such as dehulling and roasting, are applied to raw foods. Roasting is a thermal process that depends on temperature time improves the extraction yield oil by generating pores in oilseed cell walls. Sesame (Sesamum indicum L.) annual plant belonging Pedaliaceae considered be on...

In order to determine optimum oven cooking procedures for lean beef, the effects of searing at 232 or 260°C for 0, 10, 20 or 30 min, and roasting at 160 or 135°C on semimembranosus (SM) and longissimus lumborum (LL) muscles were evaluated. In addition, the optimum determined cooking method (oven-seared for 10 min at 232°C and roasted at 135°C) was applied to SM roasts varying in weight from 0.5...

In Japan, maximum residue limits for pesticides (MRL) in coffee are set on green coffee beans, but not roasted coffee beans, although roasted beans are actually used to prepare coffee for drinking. Little is known about the behavior of pesticides during the roasting process. In the present study, we examined the changes in the concentration of pesticide (organochlorine: γ-BHC, chlordane and hep...

Roasting is widely applied in oil processing to improve the extraction yield and desired sensory characteristics. The current study aimed at optimizing roasting conditions (time temperature) of hemp (Cannabis sativa L.) seeds prior seed pressing antioxidant capacity, using response surface methodology based on central composite design (CCD). Hemp were roasted five temperatures (132, 140, 160, 1...

The effect of variations in temperature and roasting time on the physical properties coffee beans originating from Gayo highlands with Arabica Robusta types have been studied this paper. Physical measured include weight loss, true density, porosity, water content. measurement procedure follows Standard Nasional Indonesia (SNI) 01-2907-2008. Three levels were used study, i.e., Light Roast (159 -...
