1.What Is Sterilization And Pasteurization?
Sterilization and pasteurization are two frequently used disinfecting method for us. How to determine them? Check this.
Sterilization
Sterilization-Sourced:outsource
Sterilization adopts the thermal processing to eliminate the various bacteria. As bacteria cannot survive in the high temperature, the sterilization can clear up the affecting bacteria and leave the products away from the affect of bacteria. Usually, it can prolong the shelf life of products for several months.
Pasteurization
Pasteurization-Sourced:finamac
Pasteurization also applied the heat treatment for the products preserve. Instead of eliminating the whole bacteria, it creates the environment which benefits some bacteria and hurt other bacteria. The saved bacteria will benefit the products save and resist the pollutants for products.
2.Why You Need Sterilization And Pasteurization?
Why you need sterilization and pasteurization? The sterilization and pasteurization are two important factors for your products saving. And here are the reasons.
Products quality
Products Quality-Sourced:amautoclave
Sterilization and pasteurization are the methods which help prove the products quality and inhibit the microbe or other affecting bacteria. It decreases the possibility of deterioration and makes the products of great state for you.
Longer shelf life
Longer Shelf Life-Sourced:cpdonline
Sterilization and pasteurization can prolong the shelf life of products as it eliminates the active bacteria and makes the great protection of the pollution. It can store longer and have the shelf life longer too.
Sanitary prove
Sanitary Prove-Sourced:terrafoodtech
The heating process of sterilization and pasteurization can eliminates the affecting bacteria. The clean and bacteria free products with little affecting of pollutants can have the sanitary proved better.
3.The Common Types Of Sterilization And Pasteurization
For sterilization and pasteurization, there may be various types and methods for each. And here are the common types of sterilization and pasteurization.
Sterilization
Ultra-High-Temperature (UHT) Sterilization
Ultra High Temperature Sterilizer-Sourced:fruitprocessingmachine
Ultra high temperature sterilization means to make the sterilization by exposing the products to high temperature with a short period. It makes sure the aseptic condition of products before it is opened.
Retort Sterilization
Retort sterilizer-Sourced:retorts
Retort sterilization is the sterilization which can be applied in home. After placing the products in the container, you can then boiled it in high temperature. With high temperature and high pressure, it can be sterilized. The common use of it can be found in can production.
Cold physical sterilization
Bacterial Filters-Sourced:qmedicalindustries
Cold physical sterilization involves the sterilization with bacterial filters and radiation. You may apply the non-ionizing ultraviolet radiation, ultrasound and ionizing rays for sterilization use. The strong penetrating of the radiation makes the long shelf life of products.
Chemical sterilization
Chemical Sterilization-Sourced:pharmacyscope
There are various chemical products for chemical sterilization. And you may apply phenol derivatives, aldehydes, alcohols, oxidants, surfactants, guanidine compounds, acids and bases for chemical sterilization.
Pasteurization
Short Time/High Temperature (HTST) pasteurization
HTST Pasteurizer-Sourced:csidesigns
Short Time/High Temperature (HTST) pasteurization is one of the most common pasteurization process which means to make the high temperature in short period. There is strict standard in the this process.
Ultra-high temperature (UHT) pasteurization
UHT Pasteurizer-Sourced:wikipedia
Ultra-high temperature (UHT) pasteurization means to heating the material in high temperature. The temperature is usually around 63°C. You may have almost all bacteria killed in this high temperature.
Low-temperaturelong-time (LTLT) pasteurization
LTLT Pasteurizer-Sourced:foodtechinfo
In contrary with make the pasteurization under high temperature, LTLT pasteurization refers to kill bacteria in low temperature and long time. You should usually take 30 minutes to make the pasteurization. And its affect is great.
4.Sterilization Vs Pasteurization, What Are The Difference?
What are the difference between sterilization and pasteurization? Can you make the casual interchange? Here is the detailed difference.
Sterilization Vs Pasteurization
Sterilization | Pasteurization | |
Storing temperature | Products from sterilization can be stored in the higher temperature. | Products from pasteurization should be stored in fridge for the microbe inhibiting. |
Organoleptic properties | The high temperature of sterilization may in some way affect the flavor and decrease the nutrition. | The low temperature of pasteurization contains the nutrition and favor of products. |
Shelf life | Products of sterilization can be stored longer as it has all microbe and bacteria destroyed. And the shelf life is usually 4 months. | Products of pasteurization has shorter shelf life compared with sterilization. The leaving bacteria required the low temperature to be saved suitably. |
Food PH and acidity | Food PH and acidity affect in many way the disinfecting manner. The food with higher PH and acidity required the sterilization which usually gives the high temperature. | Food PH and acidity which is neutral or acid may be better cared with pasteurization which makes the low temperature dealing. |
Microbe destroy | Sterilization destroyed all types of microbes to make the complete sterility environment. | Pasteurization killed the affecting microbes and left some beneficial one alone. |
Industry application | Sterilization can be widely used in laboratory equipment, pharmaceutical industry, dietary industry, can industry and dentist industry and so on. | Pasteurization is usually applied in food industry, drink industry, dietary industry and so on. |
Equipment applying | Sterilization usually applied tubular heat exchangers and plate heat exchangers for its disinfecting equipment. | Pasteurization usually applies plate heat exchangers and tubular heat exchangers as its disinfecting equipment. |
Cost | Sterilization equipment costs more compared with pasteurization equipment and it consumes more in disinfecting process. | Pasteurization makes less expense in equipment and energy consuming. |
Environment affect | As sterilization consumes more in energy, it has larger environment affect for world. | Pasteurization consumes less and is thus more friendly to environment. |
5.How DoesSterilization And Pasteurization Work?
How does sterilization and pasteurization work? Here is the working process of sterilization and pasteurization.
Sterilization working
Sterilization Working-Sourced:lso-inc
As the many types of germs and microbes have the different heat resisting ability, sterilization adopts the strong heating process to eliminate the all bacteria. The high temperature of sterilization changes the structure of microorganisms and makes damage to microbe’s important parts. At the main time, the nutrition and flavor may change in the process.
Pasteurization working
Pasteurization Working-Sourced:brewersassociation
Pasteurization makes the same process as sterilization. Pasteurization applies the precisely moderated temperature and the strict time combination to eliminate the microbe or germs which may lead the spoiling of products and stay the microbes which maintain the nutrition and special flavor of food.
