Flash Pasteurization
Flash pasteurization, also called "high-temperature short-time" (HTST) processing, is a method of heat pasteurization of perishable beverages like fruit and vegetable juices, beer, wine, and some dairy products such as milk. Compared with other pasteurization processes, it maintains color and flavor better, but some cheeses were found to have varying responses to the process. Flash pasteurization is performed to kill spoilage microorganisms prior to filling containers, in order to make the products safer and to extend their shelf life compared to the unpasteurised foodstuff. For example, one manufacturer of flash pasteurizing machinery gives shelf life as "in excess of 12 months". It must be used in conjunction with sterile fill technology (similar to aseptic processing) to prevent post-pasteurization contamination. The liquid moves in a controlled, continuous flow while subjected to temperatures of 71.5 °C (160 °F) to 74 °C (165 °F), for about 15 to 30 se ...

Pasteurization
Pasteurization or pasteurisation is a process of food preservation in which packaged and non-packaged foods (such as milk and fruit juices) are treated with mild heat, usually to less than , to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process. The process is named after the French microbiologist Louis Pasteur whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety. By the year 1999, most liquid products were heat treated in a continuous system where heat can be applied using a plate heat exchanger or the direct or indirec ...

Pathogen
In biology, a pathogen ( el, πάθος, "suffering", "passion" and , "producer of") in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. The term ''pathogen'' came into use in the 1880s. Typically, the term ''pathogen'' is used to describe an ''infectious'' microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as helminths and insects, can also cause or transmit disease. However, these animals are usually referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while parasitology refers to the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time frames, but soil has the longest ...

Ultra-high-temperature Processing
Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization is a food processing technology that sterilizes liquid food by heating it above – the temperature required to kill bacterial endospores – for 2 to 5 seconds. UHT is most commonly used in milk production, but the process is also used for fruit juices, cream, soy milk, yogurt, wine, soups, honey, and stews. UHT milk was first developed in the 1960s and became generally available for consumption in the 1970s. The heat used during the UHT process can cause Maillard browning and change the taste and smell of dairy products. An alternative process is flash pasteurization, in which the milk is heated to for at least 15 seconds. UHT milk packaged in a sterile container has a typical unrefrigerated shelf life of six to nine months. In contrast, flash pasteurized milk has a shelf life of about two weeks from processing, or about one week from being put on sale and, some can even last to many ...

Odwalla
Odwalla Inc. () was an American food product company selling fruit juices, smoothies and food bars founded in Santa Cruz, California in 1980 and from 1995–2020 was headquartered in Half Moon Bay, California. Odwalla's products included juices, smoothies, soy milk, bottled water, organic beverages, and several types of energy bars, known as "food bars". The company experienced strong growth after its incorporation in 1985, expanding its distribution network from California to most of North America, and went public in 1993. A period of decline occurred as the result of a fatal outbreak of ''E. coli'' O157:H7 in 1996 that was caused by using bruised fruit that had been contaminated. Odwalla originally sold unpasteurized juices, claiming that the process of pasteurization altered the flavor of the juice. Following the ''E. coli'' outbreak and the death of at least one child, Odwalla adopted flash pasteurization and other sanitization procedures. Odwalla recalled its juices and ...

Tropicana Products
Tropicana Brands (''pronounced as'' traa·puh·ka·nuh) is a former American fruit-based beverage company. It was founded in 1947 by Anthony T. Rossi in Bradenton, Florida. Between 1998 and 2021 it was a subsidiary of PepsiCo, but in August 2021, 61% of Tropicana was sold along with the rest of PepsiCo's juice brand portfolio for $3.3 billion to PAI Partners. PepsiCo retained the remaining 39% of ownership. History Anthony T. Rossi Anthony T. Rossi was born in Sicily and studied until high school. He immigrated to the United States in 1921 at the age of 21 years. He drove a taxi, was a grocer in New York, then worked as a farmer in Virginia, and then moved to Florida in 1940 where he farmed and was a restaurateur. His first involvement with the Florida citrus industry was fresh fruit gift boxes sold by Macy's and Gimbels department stores in New York City, New York. In 1947, Rossi settled in Palmetto, Florida and began packing fruit gift boxes and jars of sectioned fruit fo ...

Log Reduction
Log reduction is a measure of how thoroughly a decontamination process reduces the concentration of a contaminant. It is defined as the common logarithm of the ratio of the levels of contamination before and after the process, so an increment of 1 corresponds to a reduction in concentration by a factor of 10. In general, an -log reduction means that the concentration of remaining contaminants is only times that of the original. So for example, a 0-log reduction is no reduction at all, while a 1-log reduction corresponds to a reduction of 90 percent from the original concentration, and a 2-log reduction corresponds to a reduction of 99 percent from the original concentration. Mathematical definition Let and be the numerical values of the concentrations of a given contaminant, respectively before and after treatment, following a defined process. It is irrelevant in what units these concentrations are given, provided that both use the same units. Then an and -log reduction is achie ...

Raw Milk
Raw milk or unpasteurized milk is milk that has not been pasteurized, a process of heating liquid foods to kill pathogens for safe consumption and extending the shelf life. Proponents of raw milk have asserted numerous supposed benefits to consumption, including better flavor, better nutrition, contributions to the building of a healthy immune system and protection from allergies. However, no clear benefit to consumption has been found, and the medical community notes there is increased risk of contracting dangerous milk borne diseases from these products substantial evidence of this increased risk, combined with a lack of any clear benefit, has led countries around the world to either prohibit the sale of raw milk or require warning labels on packaging when sold. In countries where it is available for sale, its availability and regulations around its sale vary. In the EU, member states can prohibit or restrict the sale of raw milk, but it is not banned outright; in some member ...

Coxiella Burnetii
''Coxiella burnetii'' is an obligate intracellular bacterial pathogen, and is the causative agent of Q fever. The genus ''Coxiella'' is morphologically similar to ''Rickettsia'', but with a variety of genetic and physiological differences. ''C. burnetii'' is a small Gram-negative, coccobacillary bacterium that is highly resistant to environmental stresses such as high temperature, osmotic pressure, and ultraviolet light. These characteristics are attributed to a small cell variant form of the organism that is part of a biphasic developmental cycle, including a more metabolically and replicatively active large cell variant form. It can survive standard disinfectants, and is resistant to many other environmental changes like those presented in the phagolysosome. History and naming Research in the 1920s and 1930s identified what appeared to be a new type of ''Rickettsia'', isolated from ticks, that was able to pass through filters. The first description of what may have been ''Coxi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Juice
Juice is a drink made from the extraction or Cold-pressed juice, pressing of the natural liquid contained in fruit and vegetables. It can also refer to liquids that are flavored with concentrate or other biological food sources, such as meat or seafood, such as clam juice. Juice is commonly consumed as a beverage or used as an ingredient or flavoring in foods or other beverages, as for smoothies. Juice emerged as a popular beverage choice after the development of pasteurization methods enabled its preservation without using fermentation (which is used in wine production). The largest fruit juice consumers are New Zealand (nearly a Cup (unit), cup, or 8 ounces, each day) and Colombia (more than three quarters of a cup each day). Fruit juice consumption on average increases with a country's income level. Etymology The word "juice" comes from Old French in about 1300; it developed from the Old French words "''jus, juis, jouis''", which mean "liquid obtained by boiling herbs". Th ...

Aseptic Processing
Aseptic processing is a processing technique wherein commercially thermally sterilized liquid products (typically food or pharmaceutical) are packaged into previously sterilized containers under sterile conditions to produce shelf-stable products that do not need refrigeration. Aseptic processing has almost completely replaced in-container sterilization of liquid foods, including milk, fruit juices and concentrates, cream, yogurt, salad dressing, liquid egg, and ice cream mix. There has been an increasing popularity for foods that contain small discrete particles, such as cottage cheese, baby foods, tomato products, fruit and vegetables, soups, and rice desserts. Aseptic processing involves three primary steps: thermal sterilization of the product, sterilization of the packaging material, and conservation of sterility during packaging. To ensure commercial sterility, aseptic processing facilities are required to maintain proper documentation of production operations, showing that ...

Shelf Life
Shelf life is the length of time that a commodity may be stored without becoming unfit for use, consumption, or sale. In other words, it might refer to whether a commodity should no longer be on a pantry shelf (unfit for use), or no longer on a supermarket shelf (unfit for sale, but not yet unfit for use). It applies to cosmetics, foods and beverages, medical devices, medicines, explosives, pharmaceutical drugs, chemicals, tyres, batteries, and many other perishable items. In some regions, an advisory ''best before'', mandatory ''use by'' or ''freshness date'' is required on packaged perishable foods. The concept of expiration date is related but legally distinct in some jurisdictions. Background Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display.
