Strained yogurt, Greek or Greek-style yogurt, [2] yogurt cheese, sack yogurt or kerned yogurt is yogurt that has been strained to remove most of its whey, resulting in a thicker consistency than normal unstrained yogurt, while still preserving the distinctive sour taste of yogurt. Like many types, strained yogurt is often made from milk enriched by boiling off some water content, or by adding extra butterfat and powdered milk. In Europe and North America, it is often made from low-fat or fat-free cow's milk. In Iceland a similar product named skyr is made. [3] [4]
Strained yogurt is usually marketed in North America as "Greek yogurt" and in the United Kingdom as "Greek-style yoghurt", [5] though strained yogurt is also widely eaten in Levantine, Eastern Mediterranean, Middle Eastern, Central Asian, South Asian, and Eastern European cuisines, where it is often used in cooking, as it curdles less readily when cooked. It is used in a variety of dishes, cooked or not, savory or sweet. Straining makes even non-fat yogurt varieties thicker, richer, and creamier than unstrained. Since straining removes the whey, more milk is required to make strained yogurt, increasing the production cost. In Western Europe and the United States, strained yogurt has increased in popularity compared to unstrained yogurt. Since the straining process removes some of the lactose, strained yogurt is lower in sugar than unstrained yogurt. [6]
It was reported in 2012 that most of the growth in the US$4.1 billion American yogurt industry came from the strained yogurt sub-segment, typically marketed as "Greek yogurt". [7] [8] In the US, there is no legal or standard definition of Greek yogurt, and yogurt thickened with thickening agents, typically pectin, locust bean gum, starches or guar gum, may also be sold as "Greek yogurt". [9]
In English, strained yogurt only became well known outside of immigrant communities in the 1980s, [10] when it was imported into the United Kingdom by the Greek company Fage, under the brand name "Total". Starting in the 1980s, essentially all yogurt in the UK called "Greek yogurt" was strained yogurt made in Greece. [11]
In the cuisines of many Iranian and Turkic people (e.g. in Afghan, Tatar, Tajik, Uzbek, and other Central Asian cuisines), a type of strained yogurt called chak(k)a [4] or suzma is consumed. It is obtained by draining qatiq, a local yogurt variety. By further drying it, one obtains qurut, a kind of dry fresh cheese.[ citation needed ][ verification needed ]
Strained yogurt is made by straining the liquid out of yogurt until it takes on a consistency similar to a soft cheese. Strained yogurt is known as labneh (labna, labni, labne,lebni, or labani; Arabic: لبنة) in the countries of the Levant, Armenia, Egypt, and the Arabian Peninsula. Labaneh bil zayit, "labaneh in oil", consists of small balls of dry labneh, sometimes covered with herbs or spices, kept in olive oil, where it can be preserved for over a year. As it ages it turns more sour.[ citation needed ][ verification needed ]
The flavor depends largely on the sort of milk used: labneh from cow's milk has a rather mild flavor. Also the quality of olive oil topping influences the taste of labneh. Milk from camels and other animals is used in labneh production in Saudi Arabia and other Gulf Arab countries.[ citation needed ][ verification needed ]
Labneh is a popular mezze dish and sandwich ingredient, especially in the Levantine countries of Lebanon, Syria, Jordan, and Palestine. A common sandwich in the Middle East is one of labneh, mint, zaatar, and olive on flatbread. It is a common breakfast dip. [12] It is usually eaten spread on a plate and drizzled with olive oil, and often dried mint. It is also often paired as a dip with the mixed herb blend za'atar.[ citation needed ][ verification needed ]
Bedouin also produce a dry, hard labneh (labaneh malboudeh, similar to Central Asian qurut) that can be stored: strained labneh is pressed in cheese cloth between two heavy stones and later sun-dried. Dry labneh may be mixed with khubz (Arabic bread), water, animal fat, and salt, and rolled into balls.[ citation needed ][ verification needed ]
Labneh is the main ingredient in jameed, which is used in mansaf, the national dish of Jordan.[ citation needed ][ verification needed ]
In Egypt, it is eaten with savory accompaniments such as olives and oil, and also with a sweetener such as honey, as a snack or breakfast food. Areesh cheese (or arish, Arabic : جبنة قريش) is a type of cheese that originated in Egypt. Arish cheese is made from yogurt heated slowly until it curdles and separates, then placed in cheesecloth to drain. It is similar in taste to ricotta. [13] The protein content of Areesh cheese is 17.6%. [14] Shanklish, a fermented cheese, is made from areesh cheese. [15]
As in Greece, strained yogurt is widely used in Cypriot cuisine both as an ingredient in recipes as well as on its own or as a supplement to a dish. In Cyprus, strained yogurt is usually made from sheep's milk.[ citation needed ]
Strained yogurt in Iran is called mâst chekide and is usually used for making dips, or served as a side dish. In Northern Iran, mâst chekide is a variety of kefir with a distinct sour taste. It is usually mixed with fresh herbs in a pesto-like purée called delal. Yogurt is a side dish to many Iranian meals. Strained yogurt is used as dips and various appetizers with multitudes of ingredients: cucumbers, onions, shallots, fresh herbs (dill, spearmint, parsley, cilantro), spinach, walnuts, zereshk, garlic, etc. The most popular appetizers are spinach or eggplant borani, ‘'Mâst-o-Khiâr'’ with cucumber, spring onions and herbs, or ‘'Mâst-Musir'’ with wild shallots. Strained yogurt in Balochistan is called sheelanch and is used for making dips served with dates, or served as a side dish.[ citation needed ]
In Turkey, strained yogurt is known as süzme yoğurt [16] ("strained yogurt") or kese yoğurdu ("bag yogurt"). [17] Water is sometimes added to it in the preparation of cacık, when this is not eaten as a meze but consumed as a beverage. Strained yogurt is used in Turkish mezzes and dips such as haydari.[ citation needed ][ verification needed ]
In Turkish markets, labne is also a popular dairy product but it is different from strained yogurt; it is yogurt-based creamy cheese without salt, and is used like mascarpone. [18]
In Armenia, strained yogurt is called kamats matzoon . Traditionally, it was produced for long-term preservation by draining matzoon in cloth sacks.[ citation needed ]
In South Asia, regular unstrained yogurt (curd), made from cow or water buffalo milk, is often sold in disposable clay bowls called kulhar. Kept for a couple of hours in its clay pot, some of the water evaporates through the unglazed clay's pores. It also cools the curd due to evaporation.[ citation needed ][ verification needed ]
But true strained yogurt, chakka, is made by draining the yogurt in a (preferably muslin) cloth. [19] It is hung for 12 to 18 hours to allow some of the whey to drain off. This technique is popular in India and Pakistan. [20] Shrikhand is a dish made with chakka, sugar, saffron, cardamom, pureed or diced fruit and nuts mixed in; it is often eaten with poori. It is particularly popular in the states of Gujarat and Maharashtra, where dairy producers market shrikhand in containers.[ citation needed ][ verification needed ]
Chakka is also eaten in Pashtun-dominated regions of Pakistan with rice and meat dishes. [21]
Strained yogurt (Greek : στραγγιστό γιαούρτι, romanized: strangistó giaoúrti) is used in Greek food mostly as the base for tzatziki dip and as a dessert, with honey, sour cherry syrup, or spoon sweets often served on top. A few savory Greek dishes also use strained yogurt. In Greece, strained yogurt, like yogurt in general, is traditionally made from sheep milk. Fage International S.A. began straining cow milk yogurt for industrial production in Greece in 1975, which is when it launched its brand "Total". [22]
In Albania, strained yogurt is called "salcë kosi" (yogurt sauce). Yogurt is drained in a cloth sack from few hours to overnight. The water released from this process is called "hirrë" and can be used to preserve cheese or as a drink.
In Bulgaria, where yogurt is considered to be an integral part of the national cuisine, strained yogurt is called "tsedeno kiselo mlyako" (Bulgarian : цедено кисело мляко), and is used in a variety of salads and dressings.
A variety of strained yogurt called "basa" is a traditional variety of cheese from the region of Lika in Croatia. In Serbia and North Macedonia, it is also known as kiselo mleko (кисело млеко).
A type of strained yogurt named ymer is available in Denmark. In contrast to the Greek and Turkish variety, only a minor amount of whey is drained off in the production process. [23] Ymer is traditionally consumed with the addition of ymerdrys (lit.: ymer-sprinkle), a mixture of roasted bread crumbs of rugbrød rye bread mixed with brown sugar. Like other types of soured dairy products, ymer is often consumed at breakfast. Strained yogurt topped with muesli and maple syrup is often served at brunch in cafés in Denmark.[ citation needed ][ verification needed ]
Strained yogurt is known as hangop, literally meaning 'hang up' in the Netherlands. It is a traditional dessert. Hangop may also be made using buttermilk.[ citation needed ][ verification needed ]
In March 2020, it was reported that strained yogurt makes up 28% of the value of the "natural yogurt" category in the United Kingdom.[ citation needed ] In the UK, strained yogurt can only be marketed as "Greek" if made in Greece. Strained cow-milk yogurt not made in Greece is typically sold as "Greek style" or "Greek recipe" for marketing reasons, typically at lower prices than yogurt made in Greece. Among "Greek style" yogurts, there is no distinction between those thickened by straining and those thickened through additives. [24] However, if the yogurt contains anything other than lactic products, food enzymes and micro-organism cultures a list of ingredients is required on packaging. [25] Strained yogurt with added fruit, honey, etc., and yogurt with reduced or no fat content, may be described as Greek-style.
In September 2012, Chobani UK began to sell yogurt made in the United States as "Greek yogurt". FAGE, a company that manufactures yogurt in Greece and sells it in the United Kingdom, filed a passing-off claim against Chobani in the UK High Court, claiming that UK consumers understood "Greek" to refer to the country of origin (similar to "Belgian beer"); Chobani's position was that consumers understood "Greek" to refer to a preparation (similar to "French toast"). Both companies relied on surveys to prove their point; FAGE also relied on the previous industry practice of UK yogurt makers not to label their yogurt as "Greek yogurt". Ultimately Mr Justice Briggs found in favor of FAGE and granted an injunction preventing Chobani from using the name "Greek yogurt". [24] In February 2014, this decision was upheld on appeal. [26] [27] Greece may now seek to protect the marketing term, "Greek yogurt", across the entire EU under protected designation of origin rules. [28]
In May 2020, British dairy company Yeo Valley entered the market with an organic product called "Super Thick Kerned Yogurt. [29] The "kerned yogurt" label was the first of its kind, coined in reference to an archaic Somerset term meaning "thickened", which is predominantly used in relation to dairy products. [30]
A product called "Lindahls Kvarg" was launched in the UK by Nestlé [31] in 2018, and described as "Sweden's No. 1 Quark". Quark is a type of high-protein strained curd cheese widely used in Swedish cooking. The company Bio-tiful launched its kefir-quark blend, containing live cultures and protein. [32]
Since 2015, Arla has sold its own skyr product marketed as "Icelandic style yogurt". [33]
In Mexico, the thick yogurt jocoque seco was popularized by local producers of Lebanese origin and is widely available.[ citation needed ][ verification needed ]
Strained yogurt typically marketed as "Greek yogurt" has become popular in the United States and Canada, [6] where it is often used as a lower-calorie substitute for sour cream or crème fraîche. [34] Celebrity chef Graham Kerr became an early adopter of strained yogurt as an ingredient, frequently featuring it (and demonstrating how to strain plain yogurt through a coffee filter) on his eponymous 1990 cooking show, as frequently as he had featured clarified butter on The Galloping Gourmet in the late 1960s. In 2015, food market research firm Packaged Facts reported that Greek yogurt has a 50 percent share of the yogurt market in the United States. [35]
There are numerous "Greek yogurt" brands in North America. [6] FAGE began importing its Greek products in 1998 and opened a domestic production plant in Johnstown, New York, in 2008. [8] Chobani, based in New Berlin, New York, began marketing its Greek-style yogurt in 2007. The Voskos brand entered the US market in 2009 with imported Greek yogurt products at 10%, 2%, and 0% milkfat. [36] Stonyfield Farms, owned by Groupe Danone, introduced Oikos Organic Greek Yogurt in 2007; Danone began marketing a non-organic Dannon Oikos Greek Yogurt in 2011 and also produced a now discontinued blended Greek-style yogurt under the Activia Selects brand; [37] Dannon Light & Fit Greek nonfat yogurt was introduced in 2012, [38] and Activia Greek yogurt was re-introduced in 2013. [39] General Mills introduced a Greek-style yogurt under the Yoplait brand name in early 2010, which was discontinued and replaced by Yoplait Greek 100 in August 2012. [40] Activia Greek yogurt was re-introduced in 2013, and in July 2012 took over US distribution and sales of Canadian Liberté's Greek brands. In Canada, Yoplait was launched in January 2013, and is packaged with toppings. [41]
While yogurt may legally be described as "strained", modern commercial production does not usually reduce the liquid content by passing the yogurt through a filter under gravity, the usual definition of straining. The characteristic thick texture and high protein content are achieved through either or both of two processing steps. The milk may be concentrated by ultrafiltration to remove a portion of the water before addition of yogurt cultures. [42] Alternatively, after culturing, the yogurt may be centrifuged or membrane-filtered to remove whey, in a process analogous to the traditional straining step. Brands described as "strained" yogurt, including Activia Greek, Chobani, Dannon Light & Fit Greek, Dannon Oikos, FAGE, Stonyfield Organic Oikos, Trader Joe's, and Yoplait have undergone the second process. Process details are highly guarded trade secrets. Other brands of Greek-style yogurt, including Yoplait and some store brands, are made by adding milk protein concentrate and thickeners [43] to standard yogurt to boost the protein content and modify the texture. [42]
The liquid resulting from straining yogurt is called "acid whey" and is composed of water, yogurt cultures, protein, a slight amount of lactose, and lactic acid. It is costly to dispose of. [44] [45] [46] Farmers have used the whey to mix with animal feed and fertilizer. Using anaerobic digesters, it can be a source of methane that can be used to produce electricity. [47]
Strained yogurt is a good source of protein, calcium, iodine, and vitamin B12. [48] [49] The straining process, which removes liquid whey and lactose, yields higher protein content. [50] The FAO standard requires yogurt to have at least 5.6% protein content if strained, otherwise 2.7%. [51] Strained yogurt has less sugar content than other yogurts. [48]
Yogurt is a rich source of dietary minerals, with calcium, magnesium, potassium, phosphorus, and zinc higher in content than in milk. [48] [49] One negative aspect of strained yogurt is that there is greater vitamin loss through the straining process than typical yogurt; [48] in particular, the water-soluble vitamins: vitamin C, thiamin, riboflavin, niacin, pantothenic acid, biotin, folic acid, and vitamin B12 as well as vitamin A in its beta-carotene form can be lost through the straining of liquid whey from yogurt. [48]
There are no standard regulations in the market to monitor or control the composition of concentrated yogurts. [52] Carbohydrate, fat and protein contents in strained yogurts varied from 1–12, 0–20, and 3.3–11 grams per 100 grams. [52] Concentrated yogurts contain higher final total solid content than regular yogurts, possibly prolonging shelf life compared to regular yogurts. [53]
Dairy products or milk products, also known as lacticinia, are food products made from milk. The most common dairy animals are cow, water buffalo, nanny goat, and ewe. Dairy products include common grocery store food around the world such as yogurt, cheese, milk and butter. A facility that produces dairy products is a dairy. Dairy products are consumed worldwide to varying degrees. Some people avoid some or all dairy products because of lactose intolerance, veganism, environmental concerns, other health reasons or beliefs.
Yogurt is a food produced by bacterial fermentation of milk. Fermentation of sugars in the milk by these bacteria produces lactic acid, which acts on milk protein to give yogurt its texture and characteristic tart flavor. Cow's milk is most commonly used to make yogurt. Milk from water buffalo, goats, ewes, mares, camels, and yaks is also used to produce yogurt. The milk used may be homogenized or not. It may be pasteurized or raw. Each type of milk produces substantially different results.
Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacturing of cheese or casein and has several commercial uses. Sweet whey is a byproduct resulting from the manufacture of rennet types of hard cheese, like cheddar or Swiss cheese. Acid whey is a byproduct brought out during the making of acid types of dairy products, such as strained yogurt.
Cottage cheese is a curdled milk product with a mild flavour and a creamy, heterogeneous, soupy texture, made from skimmed milk. An essential step in the manufacturing process distinguishing cottage cheese from other fresh cheeses is the addition of a "dressing" to the curd grains, usually cream, which is mainly responsible for the taste of the product. Cottage cheese is not aged.
Curd is obtained by coagulating milk in a sequential process called curdling. It can be a final dairy product or the first stage in cheesemaking. The coagulation can be caused by adding rennet, a culture, or any edible acidic substance such as lemon juice or vinegar, and then allowing it to coagulate. The increased acidity causes the milk proteins (casein) to tangle into solid masses, or curds. Milk that has been left to sour will also naturally produce curds, and sour milk cheeses are produced this way.
Yoplait is the world's largest franchise brand of yogurt. It is fully owned by French dairy cooperative Sodiaal since 2021.
Whey protein is a mixture of proteins isolated from whey, the liquid material created as a by-product of cheese production. The proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin and immunoglobulins. Glycomacropeptide also makes up the third largest component but is not a protein. Whey protein is commonly marketed as a protein supplement, and various health claims have been attributed to it. A review published in 2010 in the European Food Safety Authority Journal concluded that the provided literature did not adequately support the proposed claims.
Skyr is a traditional Icelandic cultured dairy product. It has the consistency of strained yogurt, but a milder flavor. Skyr can be classified as a fresh sour milk cheese, similar to curd cheese consumed like a yogurt in the Baltic states, the Low Countries and Germany. It has been a part of Icelandic cuisine for centuries.
Kashk, qurut, chortan, or aaruul and khuruud is a range of dairy products popular in Iranian cuisine, Caucasian cuisine, and Central Asian cuisine. Kashk is made from strained yogurt, drained buttermilk or drained sour milk by shaping it and letting it dry. It can be made in a variety of forms, like rolled into balls, sliced into strips, and formed into chunks.
Activia is a brand of yogurt owned by Groupe Danone and introduced in France in 1987. As of 2013, Activia is present in more than 70 countries and on 5 continents. Activia is classified as a functional food, designed to improve digestive health.
Liberté Inc. is a Canadian producer and distributor of dairy and deli foods, based in the Saint-Hubert borough of Longueuil, Quebec.
Fage International S.A. is an international dairy company founded in Athens, Greece, and as of 2012 headquartered in Strassen, Luxembourg. It is one of the major dairy brands in Greece. It manufactures dairy products including milk, yogurt and ice cream. The word φάγε is both the singular imperative verb meaning 'Eat!' and the initials Φ.Α.Γ.Ε./F.A.G.E..
Soy yogurt, also referred to as soya yogurt, soygurt or yofu, is a yogurt-like product made with soy milk.
Chobani is an American food company specializing in strained yogurt. The company was founded in 2005 by Hamdi Ulukaya, a Turkish businessman. Chobani sells thick, Greek yogurt with a higher protein content than traditional yogurt and is one of the main companies to popularize this style of yogurt in the US. The company has also expanded to non-dairy, plant-based products such as dairy-free vegan yogurt and oat milk. Chobani produces a variety of Greek yogurt products, oat drinks, and snacks. Chobani's yogurt's market share in the U.S. rose from less than 1% in 2007 to more than 20% in 2021, and is the top-selling Greek yogurt brand in the United States and operates the largest yogurt facility in the world. In April 2016, Chobani announced it was giving 10 percent of its ownership stake to its employees.
Quark or quarg is a type of fresh dairy product made from milk. The milk is soured, usually by adding lactic acid bacteria cultures, and strained once the desired curdling is achieved. It can be classified as fresh acid-set cheese. Traditional quark can be made without rennet, but in modern dairies small quantities of rennet are typically added. It is soft, white and unaged, and usually has no salt added.
Sour cream is a dairy product obtained by fermenting regular cream with certain kinds of lactic acid bacteria. The bacterial culture, which is introduced either deliberately or naturally, sours and thickens the cream. Its name comes from the production of lactic acid by bacterial fermentation, which is called souring. Crème fraîche is one type of sour cream with a high fat content and less sour taste.
Jocoque or jocoqui is a Mexican dairy product based on fermented milk, from uncertain origins, influenced by Lebanese cuisine.
