Effects of post-harvest process on volatile - sensory profile for coffee in Colombia

نویسندگان

چکیده

The coffee fermentation process has been established as a determining stage regarding its quality and aroma. objective of this study was to evaluate the differences that exist between five processes within each (at different times) based on their volatile sensory profile. evaluated were dry or natural (NA), semi-dry honey (HO), three variations wet process, called: conventional aerobic (AC), with previous in cherry (AFC) anaerobic (ANFC). NA obtained highest score profile statistically from other processes. determined by headspace solid phase micro-extraction (HS-SPME) gas chromatography coupled mass spectrometry (GC-MS). 51 organic compounds (VOCs) tentatively identified. main chemical families allowed differentiating groups ketones pyrroles, VOCs mainly contribute differentiate are: ethanone, 1-(1H-pyrrol-2-yl)-, 2,5-dimethylpyrazine, 2-furanmethanol, 4-vinylguayacol, 2-methylfuran, 2- butanone, 2,3-dimethylpyrazine, acetylpyrazine, 1- (2-furanylmethyl) -1H-pyrrole 2,2'-bifuran. Within (between treatments) no found final analysis, but Key words: Volatile profile; time fermentation; GC-MS; SPME.

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Biofumigation on Post-Harvest Diseases of Fruits Using a New Volatile-Producing Fungus of Ceratocystis fimbriata

A variety of volatile organic compounds (VOCs) produced by Ceratocystis fimbriata have strong bioactivity against a wide range of fungi, bacteria and oomycetes. Mycelial growth, conidial production, and spore germination of fungi and oomycetes were significantly inhibited after exposure to cultures of C. fimbriata, and colony formation of bacteria was also inhibited. Two post-harvest diseases, ...

Harvest and Post-harvest Operations

Harvest and post-harvest operations constitute principal constraints to rice production, especially in irrigated systems, because of the larger yield that has to be handled. Post-harvest crop losses of up to 35% have been reported and attributed to inefficiency of manual threshing of rice by small-scale farmers. This leads to poor grain quality and rejection of locally produced rice. The Africa...
