In 1959, the food industry saw the advent of the use of paper-foil-plastic laminated containers called tetrahedron. In 1962, a Swedish company, Tetra Pak, introduced this container to the United States market. They sold pasteurized milk and beverages in the containers. Roy Graves' company started sterilizing this container with chlorine and were able to aseptically fill and hermetically seal the container.

Foods that are processed aseptically have better nutritional, vitamin, and natural pigment retention (chlorophyll, anthocyanins, betalains, carotenoids) compared to canned food products because of the lower temperature the foods are subjected to upon processing. Aseptic processing provides flexibility in using various container sizes as well as possibility of addition of bioactive and heat-sensitive components after processing (probiotics, omega-3 fatty acids, conjugated linoleic acids).

Basidiomycetes-X can be cultured by an ordinary method. A cultured strain or the seed of BDM-X can be aseptically inoculated into agar, liquid, or sawdust media with suitable nutrients, and is cultured under appropriate temperature conditions. The optimum growth conditions are at pH 5.0 to 6.0 and at 22 to 26℃. BDM-X forms hyphal masses in light pink colonies crowded with hyphae on the media.

The use of these containers was not accepted by the American consumers due to their difficulty in opening however, it was widely used by the U.S. Navy. In 1981, hydrogen peroxide was approved by the FDA to be used to sterilize containers. Today, ships used for continental food transport are equipped with aseptic tanks to transport fruit juices. Another means of transporting aseptically processed food is the use of aseptic bags.

Aseptically processed food products can be sterilized using either direct or indirect methods of heat transfer. Direct heat transfer can be achieved through steam injection and steam infusion. Food products processed with a steam injector go through an injection chamber, where steam (150 °C) is injected into the product, then the product is flash cooled to 70 °C. Direct heat transfer is suitable for heat-sensitive foods such as milk.

The PEF temperatures are below that of the temperatures used in thermal processing. After the high voltage treatment, the juice is aseptically packaged and refrigerated. Juice is also able to transfer electricity due to the presence of several ions from the processing. When the electric field is applied to the juice, electric currents are then able to flow into the liquid juice and transferred around due to the charged molecules in the juice.

Despite the fact that, 11 years earlier, the case had been filed without penalty. In 2016 he started working on a documentary about close encounters with death. This topic is passionate It is about explaining, aseptically, the experience of being with people who have experienced clinical death and have come back to life. Interview doctors who believe in this type of experience and others who say that everything is the product of imagination.

PSGAG is first administered as a series of injections over several weeks, and can be continued once or twice a month thereafter. It is normally injected intramuscularly, though can also be injected intra-articularily (directly into the joint) in horses or subcutaneously in off-label uses. Giving PSGAG intra- articularily requires it to be given aseptically, and is sometimes supplemented by the antibiotic amikacin to prevent infection. There are no generic or human-labeled equivalents of PSGAG in the US.

Aseptic sampling is the process of aseptically withdrawing materials used in biopharmaceutical processes for analysis so as not contaminate or alter the sample or the source of the sample.ASTM E1287-89(1999) "Standard Practice for Aseptic Sampling of Biological Materials," ASTM International, West Conshohocken, PA, 1999, DOI: 10.1520/E1287-89R99, www.astm.org Aseptic samples are drawn throughout the entire biopharmaceutical process (cell culture/fermentation, buffer & media prep, purification, final fill and finishStockdale, D. Overview of Aseptic Fill/Finish Manufacturing. Am. Pharm. Rev. 2004.).

As a result, the time taken to produce bags has increased considerably and this has, unfortunately, affected the supply to patients. The MHRA stated there was no evidence to indicate that any of the Calea products manufactured and supplied to patients were contaminated. Approximately 2.8 million products were aseptically manufactured by Calea for patients and hospitals in the intervening 2015-2019 period.” The agency said they had found bacterial contamination in the production area and that the manufacturing processes in Runcorn did not meet guidelines.

Fetal bovine serum is a by-product of the dairy industry. Fetal bovine serum, as with the vast majority of animal serum used in cell culture, is produced from blood collected at commercial slaughterhouses from dairy cattle that also supply meat intended for human consumption. The first stage of the production process for fetal bovine serum is the harvesting of blood from the bovine fetus after the fetus is removed from the slaughtered cow. The blood is collected aseptically into a sterile container or blood bag and then allowed to clot.

Most of the surface microflora do not form tight associations with the plant tissue. Such associations can usually be found by visual inspection as a mosaic, de-colorization or localized necrosis on the surface of the explant. An alternative for obtaining uncontaminated explants is to take explants from seedlings which are aseptically grown from surface-sterilized seeds. The hard surface of the seed is less permeable to the penetration of harsh surface sterilizing agents, such as hypochlorite, so the acceptable conditions of sterilization used for seeds can be much more stringent than for vegetative tissues.

Aseptic Processing achieves sterility through a flash- heating process with temperatures ranging from 91 °C to 146 °C and is minimally processed. 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. Riboflavin, pantothenic acid, biotin, niacin, and vitamin B6 are unaffected. Approximately 10% of thiamine and vitamin B12, approximately 15% of folic acid and pyridoxine, and approximately 25% of vitamin C are lost during aseptic processing.

Neither the FDA nor other regulatory agency maintains a list of recognized processing authorities, however, certain organizations are widely recognized within government agencies and the industry as having the experience and expertise. The FDA regulations rely upon aseptic processing and packaging authorities to establish parameters for sterilization of product, packages, and equipment so that commercial sterility of the end product is assured. The forms presently used to file aseptic processes for low-acid foods with the FDA is Form 2541c. Processes for acidified foods that are aseptically processes and packaged are filed under 2541a.

In 1947, Rossi purchased a small orange juice company in western Florida and thus began the Tropicana Products company. Tropicana's early distribution of fresh orange juice was by way of hand-delivered juice jars to nearby homes, but demand grew, especially in New York City. In what came to be his trademark business style, he approached the challenge at each step of the process: product, transportation, packaging, etc. A major breakthrough came in 1954, when Rossi invented and patented a pasteurization process to aseptically pack pure chilled juice in glass bottles, allowing it to be shipped and stored without refrigeration.

Blow-Fill-Seal (BFS) technology is a manufacturing technique used to produce small, (0.1mL) and large volume, (500mL +) liquid-filled containers. Originally developed in Europe in the 1930s, it was introduced in the United States in the 1960s, but over the last 20 years it has become more prevalent within the pharmaceutical industry and is now widely considered to be the superior form of aseptic processing by various medicine regulatory agencies including the U.S. Food and Drug Administration (FDA) in the packaging of pharmaceutical and healthcare products. The basic concept of BFS is that a container is formed, filled, and sealed in a continuous process without human intervention, in a sterile enclosed area inside a machine. Thus this technology can be used to aseptically manufacture sterile pharmaceutical liquid dosage forms.

This process involved four steps: #Sterilization of product by heating and immediate cooling #Sterilization of containers and lids using steam #Filling of cooled products aseptically into previously sterilized containers #Sealing of lids at an atmosphere of saturated or super heated steam The Dole aseptic machine overcame the hindrances that caused HCF's failure, since it was able to process various container sizes, needed less maintenance time, and cost less. The quality of products processed was consistent regardless of its container size, an important characteristic for heat sensitive foods, due to its short processing time. Split pea soup was treated using the Dole aseptic machine at the following dosage: heat time of for 3.53 seconds, hold time of 8.8 seconds, and cooling to in 14.0 – 17.0 seconds, compared to the normal processing time of 40–70 minutes at . The lack of consumer interest drove foods that were processed in the Dole aseptic machine to be discontinued.
