ETO sterilization for spice

There are three types of sterilization for spice(esterilización de óxido de etileno )(EtO, gamma, steam) :

with eo gas(eto sterilization)– spices treated with ethylene oxide (EtO) ,

with irradiation– spices treated with radiation (e.g. gamma rays, x-rays),
with steam(high temperature,and water steam).

1. Ethylene oxide sterilization (ETO)exposes the product to ETO gas under controlled conditions in a sealed chamber, to kill bacteria in the product.

Ventaja: este es un método de esterilización rentable y ampliamente utilizado que ha sido común durante muchos años. Cuando compra la máquina, puede esterilizarla usted mismo y el costo es muy económico. Gran volumen (1-36 paletas) (alrededor de 1-35 toneladas de especia una vez, dependiendo de la densidad de la especia)
Desventaja: el ETO es un gas muy regulado. Y llevará más tiempo que las otras dos formas de esterilización (puede instalar una sala de precalentamiento y una sala de aireación para resolver este problema).

2. Irradiation exposes the product to gamma rays or electron beam radiation to sterilize it.
advantage: Most effective method and no chemicals are used in this process
Disadvantages: expensive price, will cause damage to the package, and public pressure due to the negative connotations of radiation has resulted in specific labeling requirements to disclose that the product is irradiated. That can be unappealing to consumers.

3. Steam sterilization is a process that uses hot steam in a controlled environment to heat the product.
advantage: No chemicals or radiation are used in this process.
disadvantage: high temperature, and if any moisture is introduced to the product, it can result in caking and molding, and change the color and flavor of spice.
