The coffee aroma is one of the most important quality evaluation criteria employed for coffee commercialization and consumption. The purpose of this study was following the roasting process VOCs creations with the novel Electronic Nose equipped whit 2 of 6 MOX nanowire sensors. The nanowires exhibit exceptional crystalline quality and a very high length-to-width ratio, resulting in enhanced sen...

Coffee is one of mankind's most popular beverages obtained from green coffee beans by roasting. Much effort has been expended towards the chemical characterisation of the components of the roasted coffee bean, frequently termed melanoidines, which are dominated byproducts formed from its most relevant secondary metabolites - chlorogenic acids. However, impeded by a lack of suitable authentic re...

This paper covers the post-harvest aspects, processing and quality assurance for speciality/organic coffee products. It starts with the origins of coffee, what aspects provide inherent quality, and diseases that deter quality. It then touches on coffee harvesting, the timing for harvesting and development of fruit color. It discusses picking systems, both manual and mechanical and their effects...

Recovery of iron from iron-rich diasporic bauxite ore via reductive roasting followed by magnetic separation has been explored recently. However, the efficiency of alumina extraction in the non-magnetic materials is absent. In this paper, a further study on the digestion of alumina by the Bayer process from non-magnetic material obtained after magnetic separation of reduced iron-rich diasporic ...

high nutritional value and existence of bioactive components in sesame seeds converted it to a valuable food. one of the methods to increase per capita consumption is processing of sesame with different ways such as production of sesame milk. in this study, the effect of blanching time (0 as a control sample, 15 and 30 min) at 95°c and roasting temperature (0 as a control sample and 145°c) for ...

Abstract Cocoa bean shell is a waste from the chocolate processing industry that has not been used optimally and still contains 5.78% polyphenols which potential as source of natural antioxidant compounds. The processed in with light, medium high roasting, based on desired product. purpose this study was to determine polyphenol content activity dry fermented cocoa shells result best degree roas...

The effects of food processing and or cooking practices in the variations in morphological changes in tissues were investigated. The relationship between consumption of charred meat, which is believed to be rich in nitrosamine, by pregnant mothers and the adverse effects on the growth of their offsprings, alterations in morphology of tissues like liver and pancreas were studied. Meat was subjec...

Roasted and non roasted full fat or partially defatted flaxseed flours (Linum Usitatissimum) were evaluated for their proximate composition, mineral profile and functional properties. Significant increase in the crude protein, crude fiber, ash and mineral contents in the partially defatted flaxseed flours (both roasted and non-roasted) was observed. Partial defattening improved the foam capacit...
