Mary_H,
Horseradish and turnips have abundant amounts of an enzyme known as peroxidase (really a family of enzymes). The cyanate issue is new to me. Do you have a citation?
I must be using the wrong term, because I have searched the three threads and I can't find it. For some reason, the advanced search is not letting me search under my own name for Luminol, but if you were to look for Luminol under my name, you might find the few times I have written about it. The post I'm referring to had a citation from Wikipedia.
ETA: It was cyanides.
"Luminol is used by forensic investigators to detect trace amounts of blood left at crime scenes as it reacts with iron found in hemoglobin. It is used by biologists in cellular assays for the detection of copper, iron, and cyanides, in addition to the detection of specific proteins by Western Blot."

"Cyanides are produced by certain bacteria, fungi, and algae and are found in a number of plants. Cyanides are found, although in small amounts, in certain seeds and stones, e.g., those of apple, mango, peach, and bitter almonds.[8] In plants, cyanides are usually bound to sugar molecules in the form of cyanogenic glycosides and defend the plant against herbivores. Cassava roots (also called manioc), an important potato-like food grown in tropical countries (and the base from which tapioca is made), also contain cyanogenic glycosides.[9][10]"
