Sterile Technique: The process is less complex and requires moderate investment compared to aseptic process. Complexity of the processĪseptic Technique: The process is more complex and requires high investment compared to sterile process. Also, this technique is mainly used in food canning industry to destroy Clostridium botulinum, harmful pathogens, and spores. Sterilization Technique: Sterilization technique is directly used for food (such as sterilization of milk, sauce, and fruit juices) to increase the shelf life of food. As an example, this technique is generally used for the industrial liquid whole eggs, tetra packaging milk, tomatoes, fruit juices, and gravies packaging. Food industry applicationsĪseptic Technique: Aseptic technique is commonly used in the packaging process. In addition, sterile equipment is used in an operative field in medicine or surgery in order to maintain an aseptic environment. Sterilization T echnique: Sterilization technique is mainly used in food industry for canning of foods and preservation of milk.
Thus, combinations of techniques are used to reduce the likelihood of contamination from harmful pathogens. However, direct sterilization process can cause significant tissue damages to the patient and difficult to maintain.

In a surgical application, sterile indicates totally free from all microbial forms either that can cause illness, decomposition, or fermentation. Characteristics of Aseptic and Sterile Medical applicationsĪseptic Technique: Aseptic technique is commonly used in an operative field in medicine or surgery to prevent infection. Sterilization is considered as a part of the aseptic technique. Sterile: Sterile technique is the process of removing or destroying all living microorganisms. Irradiation What is the difference between Aseptic and Sterile? Definition of Aseptic and SterileĪseptic: Aseptic technique is the reduction of contamination caused by harmful pathogenic microorganisms such as bacteria or, viruses The ultimate target of aseptic technique is the complete exclusion of pathogenic microorganisms and it is carried out in a sterile environment. For example, the autoclave was introduced by Ernst von Bergmann to sterilize surgical instruments and carbolic acid as an antiseptic solution was introduced by Baron Lister to reduce infection rates. In the food industry, this is used to enhance the shelf life of food and to ensure that food is safe for human consumption.Īseptic technique is a modern concept and it was discovered by different famous researchers in the world. In medical practices, the goal of aseptic technique is to protect patients from subsequent infectious diseases such as post-operative infection, by following processes to avoid the introduction of microbial contamination into sterile fields, sterile instrument and the operative location.
In addition, the principles of asepsis are applied in food processing industry such as aseptic packaging (Tetra pack products). This term often refers to the destruction of harmful microorganisms in an operative field in medical surgery.
What is Aseptic?Īsepsis is the condition that is free from pathogenic harmful bacteria, viruses, fungi and parasites or harmful spores. Therefore, this article explores the differences between aseptic and sterile techniques. But, in a practical situation, aseptic and sterile techniques are frequently used interchangeably. This is a broad term and sterilization can be considered as a part of the aseptic technique. Aseptic technique is the process of maintaining sterility during food processing or medical operation procedures. The key difference between Aseptic and Sterile techniques is that aseptic technique is utilized to reduce the likelihood of contamination from harmful pathogens mainly from microorganisms while sterile is a technique used to achieve an environment that is free from all living microorganisms (harmful or helpful) and their spores (reproductive structures/dormant bacterium).
