The Blood is Red Because

hitherto unnoticed details …  experiments … and more

An exciting paper by Adrie A. M. van der Hoeven, Cold Acid Postmortem Blood Most Probably Formed Pinkish-Red Heme-Madder Lake on Madder-Dyed Shroud of Turin has just been published in the Open Journal of Applied Sciences (published 30 November 2015).

The abstract reads:

The Turin Shroud was extensively scientifically investigated in 1978. In its pinkish red bloodstains, normal features of human blood were found, but also seemingly anomalous ones. In the present study, hitherto unnoticed details of the data are presented, Shroud data and more modern reference data are compared, and the results of a few experiments with linen, madder dye and blood are shown. It turns out that the Shroud’s ‘anomalous’ data are strong consistent evidence that its bloodstains contain acid heme-madder lake, of which the heme derived from cold acid postmortem blood and the madder had been applied to the Shroud at manufacture. It implies that the bloodstains were formed on the Shroud before the still not reproduced body-image was. Several other ‘red-color’ hypotheses for the Shroud’s bloodstains are discussed and dismissed.

Taken from the conclusion:

The anomalous features of the Shroud’s bloodstains, instead of being evidence against their authenticity, turn out to be very strong evidence for their authenticity…

This, too:

A few experiments confirmed that much serum can drain from human blood on a cold surface and that human blood is able to form pinkish stains on starched and madder-dyed linen that remain pinkish while simultaneously formed bloodstains on pure linen turn brown. New scientific investigations on the Shroud of Turin with more modern methods and techniques may further corroborate these conclusions.
