Would using a masticating juicer work as well as a centrifugal one?

All I found was a discussion you shared between Haidut and yourself in response to a similar question:
He also said his number is an estimate and would like to have this tested more scientifically but he lacked equipment at the time.
If you search the forms, you should be able to find a Peat reference where he says something to the extent that centrifugal is best, but a masticating one is still OK.Would using a masticating juicer work as well as a centrifugal one?
Easier to grow potatoes than to keep and milk cows.
I will be in possession of a centrifugal juicer soon and am excited to try this. Is cooking the juice absolutely necessary? I'm sure making a soup with veggies and mushrooms would be most palatable but it would be nice to know if drinking the juice raw would be an issue.
Would also like to know the answer to this, Fractality. Did you get any input elsewhere?
guessing there're two ways to make it..Some people here have tried the Peat potato protein soup and have wondered why he says he cooks it for at least 45min. Some say to inactivate some toxins, but looks like there is a very specific reason for the 45min minimum cook time and it is due to the fact that it increases recovered amount of keto acids from the liquid. Now, the study below used the boiling method in order to extract keto acids from potato slices, so it is not the same as juice where presumably the keto acids are already extracted. But the fact that the study talks about boiling (45min) increasing yield of keto acidss in the final substance makes me think that Peat is on to something when he says cook for at least 45min.
Has anybody exchanged emails with Peat on this topic?

"...An examination of the results in Table 1 indicates that the yield of both pyruvic and a-oxo-glutaric acids is increased if the maceration is made at a higher temperature. The reason for the increase is not the same for both acids, for if an extract made at a low temperature (0-18°) is subsequently heated to 100°, the yield of pyruvic acid increases markedly but that of oc-oxoglutaric acid remains stationary. The extra yield of pyruvic acid would appear to be due to the acid hydrolysis of a labile compound in the extract."
If you look at Table 1, you will see that the researchers boiled for exactly 45min to get the keto acids out of the potato and strawberry leaves. The study also also lists two other rich sourced of keto acids - peas and strawberry leaves.
Anybody up for some strawberry leaves soup?
