The effects of particle size, fermentation, roasting time and roasting temperature of cocoa nibs on cocoa butter extraction using supercritical fluid technology were studied. The effect of particle size was studied using cocoa liquor (D = 0.074 mm), ground cocoa nib (D = 0.25–0.50 mm and 1.0–1.2 mm) and whole cocoa nibs at 35 MPa, 60 C and flow rate of 2 ml/min using supercritical carbon dioxid...

Bauxite residue is a high-iron waste of the alumina industry with significant contents scandium, aluminum, and titanium. This study focuses on recovery Sc, Al, Ti, Si from iron-depleted bauxite (IDBR) into valuable products. Iron depletion was carried out using reduction roasting followed by low-intensity magnetic separation to enrich in Sc reduce an adverse effect iron scandium extraction. Hyd...

in this research roasted and sonicated rice bran were added at different levels (0, 5, 10, and 15% w/w) to wheat flour for the production of semi-voluminous bread. dough's rheological properties as well as textural and sensory characteristics of bread were investigated. the results showed that water absorption (%), development time (min) and the degree of dough softening (fu) were increased but...

Proximate, mineral and amino acid compositions of raw and processed red kidney bean (Phaseolus vulgaris L.) flour were investigated on dry weight bases with a view to finding alternative and cheaper sources of protein to solve the problem of malnutrition due to inadequate protein in nutrition which is a prevalent problem in developing world, especially in Nigeria. Processing methods (cooking, b...

OBJECTIVE This study observed the effects of cooking method and final core temperature on cooking loss, lipid oxidation, aroma volatiles, nucleotide-related compounds and aroma volatiles of Hanwoo brisket (deep pectoralis). METHODS Deep pectoralis muscles (8.65% of crude fat) were obtained from three Hanwoo steer carcasses with 1+ quality grade. Samples were either oven-roasted at 180°C (dry ...

The present investigation was undertaken to study and compare the changes in proximate principals and T 1 content in differently processed mature Indian soy genotypes. Proximate principals as moisture, proteins, carbohydrates, fat, ash, fibre and TI content were assessed in two Indian soybean genotypes viz., NRC-37 and JS335 in mature and after applying simple processing technique (soaking, boi...

Zinc ferrite (ZnFe2O4), one of the major forms zinc in electric arc furnace dust and leaching residue, is very difficult to chemically dissolve either acidic or alkaline solutions. It therefore necessary study extraction from achieve full recovery resources. In this paper, CaO was used degrade structure then ammonia method applied recover zinc. The thermodynamic analysis indicated that could re...

Coffee is one of the most popular and widely consumed beverages worldwide due to its pleasant taste and aroma. A number of studies have been performed to elucidate the possible beneficial effects of coffee consumption on human health and have shown that coffee exhibits potent antioxidant activity, which may be attributed mainly to its polyphenolic content. However, there is also evidence to sug...

Biomass was used as reducing agent to roast the Baotou low-grade limonite in a high temperature vacuum atmosphere furnace. The effect of calcination temperature, time and ratio of reducing agent on the magnetic properties of calcined ore was studied by VSM. The phase and microstructure changes of limonite before and after calcination were analyzed by XRD and SEM. The results show that in the ro...
