Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food preparation. By preserving food, food waste can be reduced, which is an important way to decrease production costs and increase the efficiency of food systems, improve food security and nutrition and contribute towards environmental sustainability. For instance, it can reduce the environmental impact of food production.
In the field of food processing, pasteurization is a process of food preservation in which packaged and unpacked foods are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. Pasteurization either destroys or deactivates microorganisms and enzymes that contribute to food spoilage or the risk of disease, including vegetative bacteria, but most bacterial spores survive the process.
Orange juice is a liquid extract of the orange tree fruit, produced by squeezing or reaming oranges. It comes in several different varieties, including blood orange, navel oranges, valencia orange, clementine, and tangerine. As well as variations in oranges used, some varieties include differing amounts of juice vesicles, known as "pulp" in American English, and "(juicy) bits" in British English. These vesicles contain the juice of the orange and can be left in or removed during the manufacturing process. How juicy these vesicles are depend upon many factors, such as species, variety, and season. In American English, the beverage name is often abbreviated as "OJ".
A fruit press is a device used to separate fruit solids—stems, skins, seeds, pulp, leaves, and detritus—from fruit juice.
Perry or pear cider is an alcoholic beverage made from fermented pears, traditionally in England, particularly Gloucestershire, Herefordshire, and Worcestershire, parts of South Wales and France, especially Normandy and Anjou, Canada, Australia and New Zealand.
Winemaking or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine-making stretches over millennia. There is evidence that suggests that the earliest wine production took place in Georgia and Iran around 6000 to 5000 B.C. The science of wine and winemaking is known as oenology. A winemaker may also be called a vintner. The growing of grapes is viticulture and there are many varieties of grapes.
Apple cider is the name used in the United States and Canada for an unfiltered, unsweetened, non-alcoholic beverage made from apples. Though typically referred to simply as "cider" in North America, it is not to be confused with the alcoholic beverage known as cider in other places, which is called "hard cider" in the US. Outside of the United States and Canada, it is commonly referred to as cloudy apple juice to distinguish it from clearer, filtered apple juice and hard cider.
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.
Apple butter is a highly concentrated form of apple sauce produced by long, slow cooking of apples with apple juice or water to a point where the sugar in the apples caramelizes, turning the apple butter a deep brown. The concentration of sugar gives apple butter a much longer shelf life as a preserve than apple sauce.
Cranberry juice is the liquid juice of the cranberry – a fruit recognized for its bright red color, tart taste, and versatility for product manufacturing. Major cranberry products include cranberry juice, dried cranberry, cranberry sauce, frozen cranberry, cranberry powder, and dietary supplements containing cranberry extracts.
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.
Grape juice is obtained from crushing and blending grapes into a liquid. In the wine industry, grape juice that contains 7–23 percent of pulp, skins, stems and seeds is often referred to as must. The sugars in grape juice allow it to be used as a sweetener, and fermented and made into wine, brandy, or vinegar.
Ice cider is the cider equivalent of ice wine: a fermented beverage made from the juice of frozen apples. Similar to ice wine, the use of frozen apples concentrates the natural sugars in the apples, resulting in a higher alcohol content than cider made by traditional methods.
Cider is an alcoholic beverage made from the fermented juice of apples. Cider is widely available in the United Kingdom and Ireland. The UK has the world's highest per capita consumption, as well as the largest cider-producing companies. Ciders from the South West of England are generally higher in alcoholic content. Cider is also popular in many Commonwealth countries, such as India, South Africa, Canada, Australia, and New Zealand. As well as the UK and its former colonies, cider is popular in Portugal, France, Friuli, and northern Spain. Germany also has its own types of cider with Rhineland-Palatinate and Hesse producing a particularly tart version known as Apfelwein. In the U.S. and Canada, varieties of alcoholic cider are often called hard cider to distinguish it from non-alcoholic apple cider or "sweet cider", also made from apples. In Canada, cider cannot contain less than 2.5% or over 13% absolute alcohol by volume.
This glossary of winemaking terms lists some of terms and definitions involved in making wine, fruit wine, and mead.
Alicyclobacillus is a genus of Gram-variable, rod-shaped, spore-forming bacteria. The bacteria are able to grow in acidic conditions, while the spores are able to survive typical pasteurization procedures.
Juice is a drink made from the extraction or 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, such as smoothies. Juice emerged as a popular beverage choice after the development of pasteurization methods enabled its preservation without using fermentation. The largest fruit juice consumers are New Zealand and Colombia. Fruit juice consumption on average increases with a country's income level.
Cherry juice is a fruit juice consisting of the juice of cherries. It is consumed as a beverage and used as an ingredient in various foods, processed foods and beverages. It is also marketed as a health supplement. It is produced by hot- or cold-pressing cherries, collecting the juice, and then filtering and pasteurizing it.
The 1996 Odwalla E. coli outbreak began on October 7, 1996, when American food company Odwalla produced a batch of unpasteurized apple juice using blemished fruit contaminated with the E. coli bacterium, which ultimately killed a 16-month-old girl and sickened 70 people in California, Colorado, Washington state, and British Columbia, of whom 25 were hospitalized and 14 developed hemolytic uremic syndrome. Odwalla made and marketed unpasteurized fruit juices for the health segment of the juice market.
Cold-pressed juice is juice that uses a hydraulic press to extract juice from fruit and vegetables, as opposed to other methods such as centrifugal or single auger.
