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.

利点: これは費用対効果が高く、長年一般的に使用されている広く使用されている滅菌方法です。機械を購入すれば、自分で滅菌することができ、コストも非常に安いです。大容量 (1-36 パレット) (スパイスの密度に応じて、一度に約 1-35 トンのスパイス)
欠点: ETO は厳しく規制されているガスです。また、他の 2 つの滅菌方法よりも時間がかかります (この問題を解決するには、予熱室と通気室を設置できます)。

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.
