The Process and compariSon In the aseptic packaging process, the food product is generally sterilised using ultra-heat treatment, where the food or drink is heated to a very high temperature, then cooled very quickly. Also, the holding tube must be designed so that no portion of the tube between the product inlet and the product outlet can be heated. Processes for acidified foods that are aseptically processes and packaged are filed under 2541a. Aseptic bag is a kind of packaging material produced by polyethylene particles as raw material, blown film, cutting, heat sealing, vacuum packaging, sterilization in a clean environment. Also, find out if the firm maintains nozzles that are used to spray chemical sterilants, or if pumps such as peristaltic pumps, are used to control sterilant spray volumes. Determine the source and obtain copies of any container closure guidelines. And, determine how the firm assures a proper switchover from water to product without causing a process deviation to occur in either the equipment sterilization or product sterilization cycle. Peroxide level (if immersion method used) or deposition (if roller applicator or fogger is used), Temperature of warming air used to transport chemical sterilants, Air or heating element temperature (for removal of H2O2 and completion of sterilization). Food products, which are not good conductors of electrical current, are not good candidates for ohmic heating. The efficiency of some pumps may be affected by viscosity of the product and the absence of pressure or backpressure in the system. With shell-in tube heat exchangers , as shown in figure 4, the tube may be coiled inside a large shell, with product also flowing through the tube in a direction opposite to the flow of heating medium. Become familiar with this form and the "Aseptic Packaging System Supplement" to the instructions for establishment registration and process filing for acidified and low-acid canned foods. At higher-pressure drops and for large particulates, a reciprocating piston pump is normally the pump of choice. [1], Meat is less likely to toughen when aseptically processed, compared to canned products. However, the assembled aseptic package is not further processed like retort products. 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 str. Loss of filter integrity is a process deviation and places the commercial sterility of all product produced in question. ), record in the EIR how the firm assures that when reassembled, it conforms to the scheduled process parameters. Loss of sterility of air or gas supplies to sterile zones. 21 CFR 113.40(g)(l)(i)(b), states in part: The temperature recording device shall be installed in the product flow at the holding-tube outlet between the holding tube and the inlet to the cooler. It goes on to say: The temperature chart shall be adjusted to agree as nearly as possible with, but to be in no event higher than, a known accurate mercury-in-glass thermometer. The sterilization of equipment or "pre-sterilization" cycle. A septic packaging can be defined as the filling of a commercially sterile product into a sterile container under aseptic conditions and hermetically sealing the containers so that reinfection is prevented. If it has an automatic flow diversion device or system, document the variables (e.g., loss of temperature, loss of pressure in a product-to-product regenerator, etc.) If the system is equipped with only one temperature indicating device, the probe for this device is normally located in the vicinity of the temperature recording device. . For highly automated systems, there are controls that, if operating properly, will automatically preclude the packaging of non-sterile product into sterile containers. Due to the significantly lower processing time and temperature range used in aseptic processing compared to conventional sterilization, such as canning, products that are aseptically processed are able to retain more nutrients. (Webfed, Pre-formed or Thermoformed are filled/sealed using Hydrogen Peroxide as a Sterilizing Medium). Steam infusion (Figure 2): where the product is sprayed into a large pressurized steam chamber and is sterilized when falling as film or droplets through the chamber. As sterilization takes place under atmospheric conditions, this means that the temperature of the can bodies and/or covers would rise no higher than 100C (212F), whereas the temperatures employed in the superheated steam unit are designed to give can temperatures of approximately 215.6-218.3C (420-425F) and cover temperatures of approximately 210-212.8C (410-415F). military. [6], In 1959, the food industry saw the advent of the use of paper-foil-plastic laminated containers called tetrahedron. [1] Indirect forms of heat transfer include: plate heat exchangers, tubular heat exchangers, or scraped-surface heat exchangers. If non-sterile water entered the filling area, this would constitute a process deviation.

Split pea soup was treated using the Dole aseptic machine at the following dosage: heat time of 140146C (280290F) for 3.53 seconds, hold time of 8.8 seconds, and cooling to 32C (90F) in 14.0 17.0 seconds, compared to the normal processing time of 4070 minutes at 115121C (240250F). Check the container/closure flow rate with a calibrated stopwatch. Aseptic processing and conventional canning are both thermal processes that include heating, holding, cooling, and packaging steps. Thermoform-fill-seal: Figure 10 shows a system which uses hydrogen peroxide and heat or the heat of co-extrusion to sterilize. Aseptic Processing and Packaging for the Food Industry | FDA The aseptic process uses the high-temperature-short-time ( HTST) method in which foods are heated at a high temperature for a short period of time. Loss of sterility in cooling water- Determine what the possibility is that there would be a loss of sterility in the cooling water and what the firms procedures are for recognizing the deviation and what corrective action would be taken. Language links are at the top of the page across from the title. Various types of flow measuring devices have been developed which indirectly provide an indication of product flow. Severely treated milk could have a bitter flavor because of proteolysis. Document that the firm's procedures are sufficient to meet the appropriate levels for these critical factors. . UHT sterilizes food at high temperatures usually above 135 C for 12 seconds. Pitch of hold tube can be determine with a T square or by using a line level. On initial inspections collect blank copies of record forms used and describe the type of information recorded. Mercury-in-glass thermometers and other temperature indicating devices are the reference instrument and, as the regulations state, shall be tested for accuracy against a known standard upon installation and at least once a year thereafter. The regulations do not require maintenance of calibration records, however, as the reference instrument for indicating the processing temperature it is important that the firm be able to document that required tests for accuracy were accomplished. The food treated using this technique was described as an "excellent cream product" and 75100 containers were produced each minute. Another means of transporting aseptically processed food is the use of aseptic bags.[4]. [7] There are numerous methods used to sterilize the containers, the most commonly used methods include: heat, hot water, chemical sterilants (hydrogen peroxide or peracetic acid), and radiation or a combination of methods. Sterile Water- In aseptic systems using metal containers and closures, if cold sterile water is directed against the bottom of the containers after filling (or on the lids prior to closing), determine the firm's controls for ensuring the sterility of the water on a continual basis. Sodium's a big one that varies widely between brands. A positive displacement pump is used as the metering (sometimes called the timing) pump because they are less sensitive to pressure drops and slippage than centrifugal pumps. If product is going directly to a filling line, product fill rates can be determined over a set time period and correlated to product flow rates. The following factors may influence the choice of packaging material for aseptically processed products: functional properties of the plastic polymer (gas and water vapor barrier properties, chemical inertness, and flavor and odor absorption or scalping), potential interactions between plastic polymer and food product, desired shelf life, economical costs, mechanical characteristics of the packaging material (molding properties, material handling characteristics, and compatibility with packaging and sterilization methods), shipping and handling conditions (toughness, compression), compliance with regulation, and targeted consumer group. There are a variety of aseptic filling and packaging systems currently used in the United States for acid and low-acid foods. Aseptic Packaging: The Process and Comparison These bags are normally pre-sterilized with radiation. [7] To achieve this, a laminate material is formed from the following components: semi-rigid paper, aluminum, and plastic. It is important that monitoring equipment be calibrated in the range of operation (e.g., if the temperature is 200C (400F) for hot air used for container sterilization, then the monitoring equipment should be calibrated near that temperature). Also, paperboard containers are more environmentally friendly since they can be more easily recycled than other glass or plastic containers.
