The extraction of high quality DNA from processed meat can often represent the crucial step in an authentication process by PCR-based methods. In this study, the effect of three different domestic cooking methods (roasting, boiling, and microwave) on DNA isolated from two beef muscles has been investigated. The quality of extracted DNA was evaluated by amplifying target sequences from mitochond...

Acrylamide or 2-propenamide an industrial chemical formed in some foods particularly starchy foods during heating process such as baking, frying and roasting. Acrylamide is proven to be carcinogenic in animals and a probable human carcinogen mainly formed in foods by the reaction of asparagine (free amino acid) with reducing sugars (glucose and fructose) as part of the Maillard reaction during ...

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 ...

At present, wet spraying is the main process for treatment of exhaust gas emitted by concentrated sulfuric acid roasting method decomposition rare earth concentrates, which not only consumes a large amount resources but also wastes residual heat corresponding to temperatures approximately 300 °C. In this paper, an dry processing technology that completely different from original spray proposed ...

In the present study, leaching behavior of scandium from limonitic laterites under sulfation roasting–water (SAL) was explored. The mineralogical analysis showed that associated with iron phase. roasting temperature played an important role in phase conversion during process. With increase 100 to 800 °C, (goethite, magnetite, and hematite) gradually converted monoclinic Fe2(SO4)3 (400 °C), then...

• A process for hazard-free treatment electrolytic manganese residue (EMR) was proposed. Almost all of the ammonia in EMR recovered by low-temperature roasting. The present could be countercurrent water-washing. toxicity leaching results after met GB 8978?1996. combined low-temperature-roasting and water-washing is investigated as a method to treat recover manganese. In this study, phase transf...

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...

This study investigates vanadium extraction from steel converter slag the LD (Linz-Donawitz) process. has been used as an active bed material in a biomass boiler combustion technique called oxygen carrier aided (OCAC). usage could be compared to roasting step common roasting-leaching method for extraction. Leaching of prior use is undesirable materials OCAC are removed. successfully leached fol...
