Over the past several decades, studies have conducted to counter this difficult challenge; however, until date, these attempts remained unsuccessful in identifying an effective single replacement material possessing all the properties of nitrite
One possible approach to resolve this problem is the use of hurdle technology in meat curing; in this approach, low levels of sodium nitrite are combined with other compounds and/or other processing technologies
It is imperative that products treated with these secondary compounds or technologies be safe for human consumption
