A case for older (cheaper) tea?


Made from leaves that have not been oxidized.

For best health benefits, I would ...

Drink later flushes of green tea if they have higher catechin levels

Drink 1st flush if it has more catechins

Drink more 1st flush to make up for lower catechins

I'm sorry to say that again you're wrong: I never said that.
Actually I've said:

As you can see I was talking about absorption, NOT extraction...
:D


Actually, you did ... hot and long for extraction, lemon drops for absorption:

And, the most important thing, is that a bioactive concentration of catechins is reached with long infusions, by 10 minutes or even more but not at 100°C.

What are you trying to demonstrate with this?

I will continue to wait for Kevin's reply. All other things are hot air to me.

No need to get defensive.

Without application, this whole debate is hot air ... It is like argument for the sake of argument and is pointless.

I am asking a pretty simple and legitimate question based upon the topic discussion and your comments and your belief system.

About catechins extraction:
"When teas were extracted using ethanol solutions, the highest extractability of total catechins was obtained in 50% (v/v) ethanol for dry tea"

http://onlinelibrary.wiley.com/doi/10.1 ... 3/abstract

and...

http://kurdchemists.org/files/Polyphenols.pdf

However I was referring to the common way of extraction: steeping tea in water. Bioactive is the key word. Bioactive concentration of catechins are reached @ 100°C for about 10 minutes.

I agree with you Chip when you say that drinking multiple infusion of ff sencha is a good way to get sufficient catechins. Steeping 4°th flush sencha @100°C for 10 minutes and some lemon juice drops is something I hope NOBODY will not try. For the series: "don't try this at home"...

Actually I prefer more FF 1sts steeps ... and second steeps ... and third steeps ... etc. :mrgreen:

Just got back from a few days in Fukushima, it's a six hour trip each way. Guess what was about the *LAST* thing on my mind while I was up there? Answering a.serrao's post where he tried to bait me. It's pretty amazing to me that he has nothing better to do with his life than to sit around waiting for me to get back from Fukushima just so he can be "right" about something so minor. This, coming from a guy who has publicly stated he will buy no Japanese green tea for the year 2011. So if there are any other of you out there that were sitting on the edge of your seat for my results (and I doubt there are), sorry - I forgot all about getting that info while I was up there.

I've pm'ed you. I've not turned it off. Don't even know how. Are you experiencing problems sending messages?
Lemme know.

I will check his settings.

He might have opted to not receive PMs at some point and does not realize it ... likely due to not enough FF Sencha. :lol: Or too much Bancha.
