The use of cacao, in its familiar food and beverage form, dates back about 3,800 years. By the time of the discovery of America by Europeans, the Aztecs and Mayans had developed methods for drying, roasting and grinding cacao beans for use in beverages and foods. Today, the same processes are used, but have been adapted to modern machinery. The current study was conducted to compare the traditi...

In this paper, an innovative method is proposed to upgrade iron and remove phosphorus from high-phosphorus oolitic hematite ore by the sodium magnetization roasting–magnetic separation–sulfuric acid hydroxide leaching process. The process parameters of roasting, leaching, alkaline were optimized. results show that only adopting traditional separation, concentrate containing 57.49% Fe 1.4% P2O5 ...

BACKGROUND The paper looks at the levels of canolol, tocopherols and antioxidant activity in cold-pressed and hot-pressed rapeseed oils produced from seeds of various moisture levels (5%, 7.5%, and 10%). The paper also considers the effects of seed roasting on the levels of these compounds. METHODS The material used for the tests was rapeseed cv. Adrianna. The quality of the oils obtained is ...

BACKGROUND Fundamental in traditional postpartum recovery in Lao PDR is the use of hotbeds, mother roasting, steam sauna and steam baths. During these treatments medicinal plants play a crucial role, but little has been published about how the treatments are carried out precisely, which species are used, the medicinal properties of these species, and the medicinal efficacy of their chemical con...

BACKGROUND The most common form of utilization of sesame seed is its roasting, which supplies nutrients to the diet. Therefore, in view of the nutritional values of sesame seeds, the present study aimed at investigating the effect of roasting and fermentation 011 the nutritional quality of sesame flour. MATERIAL AND METHODS Nigeria grown white sesame seeds (NC'RI-98-60) were collected from Na...

This paper investigated a pellet ore production process in which vanadium was extracted from and titanium magnetite concentrates using sulfuric acid leaching. Calcium magnesium were added to the iron concentrate during produce calcium vanadate after roasting. The pellets leached with solution extract V5+. resulting had compressive strength of 3375 N primary roasting, good morphology leaching, s...

Similar to acrylamide, furan is a process contaminant which evolves within the production and preparation of food during heat treatment (sterilising, roasting, baking) from natural components of the food. So far, reducing sugars, amino acids, ascorbic acid, unsaturated fatty acids and carotenoids were identified as possible precursors transforming into furan under the influence of heat. The fol...

Six mature wethers (BW 72 kg) with ruminal, duodenal, and ileal cannulas were fed a control (no added soybean meal [SBM]) diet or diets containing unheated SBM or SBM roasted at 165 degrees C for 75, 150, 180, or 210 min in a 6 x 6 Latin square experiment. Concentrations of indicators of heat exposure (ADIN, ADF, NDF) in SBM increased with increasing roasting time. Duodenal flows of total N, no...

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...
