Roasted pistachios are among the most delicious nuts in the world. In addition to their pleasant taste, they have significant nutritional and antioxidant effects. This study aims to evaluate the nutritional, sensory, color, and texture attributes of roasted pistachio nuts using fixed and rotary methods at 160 °C during three storage times of 0, 3, and 6 months, at the ambient temperature (20±2°...

Sesame (Sesamum indicum L.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. Some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. The purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (TPC) of sesame seeds when roas...

The orthogonal array design has been used to determine the optimum conditions for gold recovery from Zarshuran refractory gold sulfide ore (Iran) by direct cyanidation and roasting-cyanidation. The Taguchi method was used as the experimental design to determine the optimum conditions of dissolution behavior of gold with cyanidation and roasting-cyanidation from Zarshuran refractory gold ore . T...

The occurrence of furan in some food products has already been known for a few decades, and it has been reconfirmed in more recent investigations that furan is present in a variety of foodstuffs. This list of products includes roasted coffee, which has been shown to generate furan as a result of the heat treatment at roasting which is applied to achieve the desired aroma and flavour profile of ...

Fuel oil used in power plants contain metal impurities like Vanadium. After combustion, this metal remains in boiler fuel ash in the form of oxide. In this research, extraction of Vanadium oxide from fuel ash has been investigated. Two processes were used for this purpose. A pyro- hydrometallurgy and a hydrometallurgy process. In the pyro-hydrometallurgy process, using sodium carbonate, salt ro...

High-chromium vanadium residue (HCVR (HCVR: high-chromium residue)) is an important secondary resource of valuable metals such as (V), chromium (Cr), and molybdenum (Mo). The mainstream technology for the utilization HCVR, Na2CO3-assisted-roasting–water-leaching method, usually requires roasting temperatures more than 800 °C results in synchronous leaching Cr with V Mo. This makes subsequent se...

The present investigation was conducted to study the true retentions of α-tocopherol, tocotrienols and β-carotene in crown daisy, unripe hot pepper, onion, garlic, and red pepper as affected by various domestic cooking methods, those were, boiling, baking, stir-frying, deep-frying, steaming, roasting, and microwaving. Fatty acid compositions were determined by GC, and HPLC were used for quantif...
