What is the recommended way to flash pasterize the maple sap? To what temperature, for how much time, then how quickly does it get cooled.... to which temperature? Out here on west coast, with our bigleafs, and their lower sugar content, this has some merit. Thanks!
Allow me to re-ask that question! To flash pasterize is to heat to an extreme temperature for less than a second, then cool. That would be done for large amounts of sap at one time. What if you just had about 10 gallons? What is the process to pasterize that amount? I know with milk you heat it to a certain temperature (less than a boil) then cool it. Will that work for maple sap also? Thanks....
There is not a quick and easy and cheap way to flash pasteurize that I am aware of. You could pasteurize in the way you describe, or with a pressure cooker, but either of those would likely result in a slight amount of color formation.

I looked into a "flash pasteurizer". For the cheapest one I could find it was $45,000. Runs off 3 phase power and is the size of a pickup. It's classified as factory or food plant equipment. And it's a whole other system to tetra pack it, I think it makes more sense to supply the sap then process it into "maple water". Unit is pretty cool looking though. Lots of stainless on that bad boy. This model is way more then 45 k but is pretty sweet looking

That is a fine looking piece of equipment!! Pretty sure there isn't enough sap out here in the entire province to make that an option... Selling the raw sap straight to the processor would be the way to go it appears, although same problem. Nobody here still believes you can tap bigleaf maples for their sap. What is the purpose of the tetrapak? Does light shorten the shelf-life of the maple water quite a bit? I see fruit juice in clear bottles, but they have probably added persevatives to lengthen help with shelf-life... Tetrapak just look a little cheap on the shelf!!
I'm going to try and put some in Mason jars and can it as I do fruits and such. 15 minutes or so at 230 should do it I'd think. Wouldn't want to do a whole bunch like that but for the novelty of it....
Woodsrover, how did this turn out for you? you boiled the sap in jars at 230 for 15, did it preserve?
There seems to be a patent on it too.

That document refers to a patent application, not a granted patent.
