Common sterilization technology for sterile packaging

With the higher demand for food packaging and preservation of consumers, improving food packaging to extend the fresh food has become an important issue for many manufacturers. At present, sterile fresh packaging in the food industry in the country is most popular, its application is not limited to fruit juice and fruit juice drinks, but also used to package milk, mineral water and wine. Common sterilization techniques include:
1, ultra-high temperature instantaneous sterilization technology
Ultra-high temperature instantaneous sterilization is the food in an instant heating to high temperature to achieve sterilization purposes. UHT method of sterilization temperature of 135 ℃ -145 ℃, just 3 seconds -5 seconds can be completely killed microbial spores. Ultra-high temperature instantaneous sterilization method is divided into direct heating UHT and indirect heating UHT method.
2, pasteurization technology
Pasteurization technology is to fill the food and sealed in the packaging container, in a certain time to keep the temperature below 100 ℃, kill the bacteria in the packaging container. Pasteurization can kill most pathogens, and for non-pathogenic spoilage of spoilage and the ability to kill is not enough, if the pasteurization and other storage means combined to achieve a certain shelf life requirements.
3, ohmic sterilization technology
Ohm sterilization is through the electrode current directly into the liquid containing the particles, the use of the dielectric properties of food itself, so that electrical energy into heat and heating food.
4, resistive heating UHT sterilization method
Resistive heating UHT sterilization is based on the fact that most of the formulated food contains free dissolved salt ions and has good conductivity. According to Ohm's law, the current can be heated by a continuous flow of material through a heated range of Food conductivity uniformity and food in the electric heater in the residence time of a direct heating of ultra-high temperature sterilization system.

Reference Standard For Seal Verification of Sterilization Pouches For Medical Devices

With the increasing demand for  sterilization pouches  of medical devices, quality and safety inspection have become more and more stringent. sterilization pouches of medical devices (blister box +  tyvek roll  material,  sterilization paper bag , etc.) as a form of packaging directly in contact with the device and used to block microorganisms. No matter what form of packaging, it has two characteristics, which can meet the sterilization operation and remain sterile until the transportation conditions are used. Therefore, relevant departments began to focus on the review requirements of sterile packaging and make specific requirements for its performance and quality.   As we all know, GB/ t19633-2005 "packaging of ultimately sterilized medical devices" is one of the authoritative standards in the current sterile packaging standards. It is equivalent to iso11607-2003 "packaging of ultimately sterilized medical devices". Clarify the basic performance req...

What is Self Seal Sterilization Pouches

  self seal sterilization pouches  is carried out in hospitals and medical or surgical sterilization manufacturing plants. Most packaging must be sterile when delivered to the end user. Medical self seal sterilization pouches provides protective envelopes for sterilization to protect against sterilization during disinfection, transportation, storage and delivery to the final home. Medical self seal sterilization pouches can assemble and secure several sterilization items required for a given surgical procedure and be ready for operation.   The term "sterilization" covers a wide range of products. A cotton ball, a cotton swab, and a tongue spatula are examples of "treatable products." Use them once and throw them away." Use once is not a synonym for cheap. Some very expensive sterilizations, such as dialysis filters, are themselves too fragile to be cleaned and reused after sterilization. To save costs, reuse is desirable. Most medical sterilization, such as sci...

Medical Non-Woven Fabrics And Biocompatibility Testing

  一、General situation of medical non-woven fabric industry Since the 21st century, especially after SARS in 2003, nonwovens technology has made great progress.With the continuous growth of consumer demand, a complete supply chain system has been formed for the processing of non-woven products, raw material production and equipment manufacturing, especially for the production and application of  medical non-woven fabrics . With the improvement of people's living standard, as well as the improvement of medical and health services, medical non-woven fabric market penetration and consumption gradually increase, while the progress of technology make medical non-woven fabric on technical level, protective function has greatly promoted, the export enterprise production of high-performance, high-quality medical non-woven popular in the United States, Japan, Europe, Oceania and other places, has five medical non-woven most developed markets, in order: the United States, Europe (mainly ...
