freeze roasted beans will lose flavor

[blaggon]

used to freeze my beans.. don't think it did it any favours either

Well, I was interested in what people had to say about the the thread 'topic'.
However I am having extreme difficulty reconciling the current discussion to the thread topic.
I don't have any problem with anyone making whatever comments they want to in a civilised manner as has been the case here.
However, as a common courtesy to all the members here- I believe it would be appropriate to start a new thread in the appropriate 'Off-Topic' Forum and continue your discussion to whatever level of tedium you so desire.... (no disrespect intended).
At least keep the discussion 'on-topic' or start a new 'topic' as you see fit....

Agree, I have opened a thread in Off Topic, anyone interested in contributing to this debate further please go there and stick to freezing of fresh roasted beans here.

Vinitase and MrJack, thanks for your posts and adding to the discussion.

[MrJack]

Chemistry is unfortunately full of such historic hangovers. One of the pitfalls of trying to categorise the universe I guess.

To answer your statement above, Oxidation will NEVER occur without Oxygen, if you have evidence that proves otherwise then I really want to see it so that I can improve my education.

I am afraid that you're both right and wrong. The original definition of oxidation certainly referred to reactions in the presence of oxygen, but it seems that the definition has since been broadened:

"The word oxidation originally implied reaction with oxygen to form an oxide, since (di)oxygen was historically the first recognized oxidizing agent. Later, the term was expanded to encompass oxygen-like substances that accomplished parallel chemical reactions. Ultimately, the meaning was generalized to include all processes involving loss of electrons" Source: Wiki

MrJack, with all due respect, please don't just throw out comments without substantiating them, it doesn't help readers to better understand what we are talking about, if you have something important to say then please support it.

Oxidation is what happens to one species in the RedOx class of reactions. It refers to a positive change in oxidation state. In a redox reaction one reagent 'loses'electrons (oxidises) and the other 'gains' electrons (reduces). In certain circumstances, the oxygen can undergo reduction.
So, oxidation does not require oxygen at all (for example, you can "burn" a match in pure chlorine gas), but it is commonly involved on Earth.

Also, the reactivity of oxygen is not because of the "spin" of the electrons.

You're entitled to your own clichés b52. I choose not to drink frozen coffee.

You are welcome to freeze and drink whatever you choose.

[blend52]

Freezer? Don't know and more importantly, don't care.

,..... if you have nothing relevant to say, dont!

Strange combination of comments in one post
Words like "throwing stones" , and "Glass houses" , or ."double standards" , spring to mind !

Living, metabolising system v coffee in a freezer. Same same? I think not....

Geez I read some "interesting" stuff some days...

Freezer? Don't know and more importantly, don't care.

I am a coffeesnob and choose not to drink rubbish. If it's even 5% degraded, I am not going there unless I just roasted the last bean grown on the planet.

Leave it for those who purchase their coffee in stoopidmarkets and guys, if you have nothing relevant to say, dont!

If you are going to "argue the science" then maybe get the basics right!

There are a few really misguided statements in there. Like complete and utter nonsense (e.g. "oxidation only occurs in the presence of oxygen").

Unlikely to matter to the majority of readers, but just adds to the misinformation cluttering the Internet.

Although this is off topic, please read this excellent article from the USA Centre for Disease Control web site:-

In Search of a Germ Theory Equivalent for Chronic Disease - Garry Egger, PhD, MPH

Prev Chronic Dis 2012;9:110301. DOI: Preventing Chronic Disease | In Search of a Germ Theory Equivalent for Chronic Disease - CDC.

Abstract

The fight against infectious disease advanced dramatically with the consolidation of the germ theory in the 19th century. This focus on a predominant cause of infections (ie, microbial pathogens) ultimately led to medical and public health advances (eg, immunization, pasteurization, antibiotics). However, the resulting declines in infections in the 20th century were matched by a rise in chronic, noncommunicable diseases, for which there is no single underlying etiology. The discovery of a form of low-grade systemic and chronic inflammation (“metaflammation”), linked to inducers (broadly termed “anthropogens”) associated with modern man-made environments and lifestyles, suggests an underlying basis for chronic disease that could provide a 21st-century equivalent of the germ theory.

Some other inks for you haba, the practice of medicine can be broadened by reading outside the curriculum, I think these might give you a different slant on illness, glad you are in the thread and welcome your comments

OXIDATIVE STRESS AS THE CAUSE OF CANCER -RAY D. STRAND, M.D.
There has been growing medical evidence that when excessive "free radicals" are allowed to exist near the nucleus of the cell, significant damage to the DNA of the cell results. This "free radical" damage may then lead to mutation of the DNA of the cell. When the cell replicates, this mutation to the DNA is carried to the next generation of cells and the actual genetic damage that occurs can lead to abnormal growth of the cell.

Maybe he figured if he started talking same or different spin, people wouldn't have the foggiest what he was on about? So he went with classical rather than quantum concepts?

There are not many people comfortable with talking straight physics and there are already posts complaining about 'mumbo-jumbo.'

If you are going to "argue the science" then maybe get the basics right!

Simply: use your tongue and decipher what your taste buds like. The End.

Ps: the whole chemistry thing was interesting to read but it went FL370 above my head..

This process is called Oxidation and is the foundation of disease and inflammation. We can use antioxidants like Vitamin C which replaces the stolen electron back to the damaged molecule to cure illness.
