ETO sterilization for spice

There are three types of sterilization for spice(stérilisation à l'oxyde d'éthylène )(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.

avantage : il s'agit d'une méthode de stérilisation rentable et largement utilisée qui est courante depuis de nombreuses années. Lorsque vous achetez la machine, vous pouvez stériliser vous-même et le coût est très bon marché. Grand volume (1 à 36 palettes) (environ 1 à 35 tonnes d'épices une fois, en fonction de la densité de l'épice)
inconvénient : l’ETO est un gaz fortement réglementé. Et cela prendra plus de temps que les deux autres méthodes de stérilisation (vous pouvez installer une salle de préchauffage et une salle d'aération pour résoudre ce problème).

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.
