Summary record of the SCOFCAH, point 4. Standing Committee On the Food Chain and Animal Health, 14 Dec 2006 (archived).
"It has been reported that some manufacturers of meat products were using standardised spinach extracts containing high levels of nitrates. Furthermore such products are labelled to imply that they contain no added preservatives. It has therefore been questioned whether such use should be considered as that of a food additive as it may exert a preservative and/or colour fixing effect."
