ETO sterilization for spice

There are three types of sterilization for spice(ethylene oxide sterilization )(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.

Vorteil: Dies ist eine kostengünstige, weit verbreitete Sterilisationsmethode, die seit vielen Jahren üblich ist. Wenn Sie die Maschine kaufen, können Sie sie selbst sterilisieren, und die Kosten sind sehr günstig. Großes Volumen (1–36 Paletten) (ca. 1–35 Tonnen Gewürz einmal, abhängig von der Gewürzdichte).
Nachteil: ETO ist ein stark reguliertes Gas. Und wird mehr Zeit in Anspruch nehmen als die beiden anderen Sterilisationsmethoden (Sie können einen Vorwärmraum und einen Belüftungsraum installieren, um dieses Problem zu lösen).

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.
