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.

الميزة: هذه طريقة تعقيم فعالة من حيث التكلفة ومستخدمة على نطاق واسع وكانت شائعة لسنوات عديدة، عند شراء الآلة، يمكنك تعقيمها بنفسك، والتكلفة رخيصة جدًا. حجم كبير (1-36 منصة نقالة) (حوالي 1-35 طن توابل مرة واحدة، اعتمادًا على كثافة التوابل)
العيب: ETO هو غاز يخضع لرقابة شديدة. وسوف تستغرق وقتاً أطول من طريقتي التعقيم الأخريين (يمكنك تركيب غرفة تسخين مسبق وغرفة تهوية لحل هذه المشكلة).

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.
