Ginseng seed oil was prepared using compressed, solvent, and supercritical fluid extraction methods of ginseng seeds, and the extraction yield, color, phenolic compounds, fatty acid contents, and phytosterol contents of the ginseng seed oil were analyzed. Yields were different depending on the roasting pretreatment and extraction method. Among the extraction methods, the yield of ginseng seed o...

Recently described scientific literature has identified the airborne presence of 2,3-butanedione (diacetyl) and 2,3-pentanedione at concentrations approaching or potentially exceeding the current American Conference of Industrial Hygienists' (ACGIH) Threshold Limit Values (TLVs) at commercial coffee roasting and production facilities. Newly established National Institutes of Occupational Safety...

In this study, the effects of oven roasting and microwave on some properties walnut kernels were determined. Roasting methods at different temperatures (70, 100, 130 ºC for one hour) powers (240, 535 830 W 5 min) applied to samples. Moisture ratio values, total phenolic compound, antioxidant activity, oil yield roasted unroasted products discussed. The highest was determined in high temperature...

A chlorination roasting-water leaching process to recover Li, Ni, Co, and Mn from spent Li-ion batteries is introduced in this paper. The key parameters were studied optimized, over 98% of 97% can be leached out under the most suitable condition 350 °C roasting temperature, 30 min time, a 2:1 mass ratio NH4Cl cathode powder. During process, first sublimated transformed into H3N···HCl(g) complex...

Rare Earth (RE) phosphors waste contains valuable rare elements (REEs), such as cerium, terbium, yttrium, and europium. In industry, the process of NaOH roasting followed by acid leaching is usually used to extract REEs from in China. Using this process, efficiencies cerium terbium are clearly lower than those other REEs, which results uneven extraction low total REE efficiency. The key reason ...

Peanut seeds were prepared with variations in roasting conditions. Positive correlations were obtained between loss of aflatoxins in the products and the roasting conditions. Seeds dryroasted at 140C for 40 min resulted in 58.8% and 64.5% reductions in AFB1 and AFG1, those roasted at 150C for 25 minutes resulted in 68.5% and 73.3% reductions in AFB1 and AFG1, respectively. Roasting at150C for 3...
