Vark or varak (Sanskrit: वरक), is any foil composed of a pure metal, typically silver, sometimes gold, used for garnishing sweets in South Asian cuisine. The silver is edible, though flavorless. Vark is made by pounding silver into a sheet a few micrometres thick, and backed with paper for support; this paper is peeled away before use. It is extremely brittle and breaks into smaller pieces if touched. Vark sheets are laid or rolled over some South Asian sweets. Edible silver and gold foils on sweets, confectionary and desserts is not unique to the Indian subcontinent; other regions such as Japan and Europe have long used precious metal foils as food cover and additive, including specialty drinks such as Danziger Goldwasser.
Vegetarian lobbyists claim that vark is commonly hammered between layers of animal fat or hide and is thus a non-vegetarian product. However, there are certain vegetarian options of vark available in markets. Like silver vark also there is gold vark in the form of gold leaf, gold flakes and gold dust.
Gold and silver are approved food foils in the European Union, as E175 and E174 additives respectively. The independent European food-safety certification agency, TÜV Rheinland, has deemed gold leaf safe for consumption. Gold and silver leaf are also certified as kosher. These inert precious metal foils are neither considered as toxic to human beings nor broader ecosystem.
One study has found that about 10% of 178 foils studied from the Lucknow (India) market were made of aluminium. Of the tested foils, 46% of the samples were found to have the desired purity requirement of 99.9% silver, whereas the rest had less than 99.9% silver. All the tested Indian foils contained on average trace levels of nickel (487 ppm), lead (301 ppm), copper (324 ppm), chromium (83 ppm), cadmium (97 ppm) and manganese (43 ppm). All of these are lower than natural anthropogenic exposures of these metals; the authors suggest there is a need to address a lack of purity standards in European Union and Indian food additive grade silver. The total silver metal intake per kilogram of sweets eaten, from vark, is less than one milligram.
Large quantities of ingested bioactive silver can cause argyria, but the use of edible silver or gold as vark is not considered harmful to the body, since the metal is in inert form (not ionic bioactive form), and the quantities involved in normal use are minuscule.
Etymology and origins
Varaka is mentioned in several ancient Sanskrit documents, particularly in Ayurvedic and medical literature. Varaka means cloth, cloak or a thing that covers something else. The word varaka is mentioned with swarna (gold), tara (silver) or rupera (silver) in these documents; the discussion is in three forms of these precious metals: patra (leaf), varaka (thin foil) and bhasma (powder). Ayurvedic documents consider silver as an antimicrobial astringent, while gold is claimed to be an aphrodisiac. This is not unique to Indian subcontinent; in Europe, edible gold (Aureum potabile) and silver were also claimed to have medicinal properties; later studies found the edible metal foils to be simply inert.
Vark is sometimes spelled Varaq, varq, vark, varkh, varakh, varkha, or waraq (Hindi: वरक़, Urdu: ورق Hindustani pronunciation: [ʋəɾəq]). The word is related to Arabic: ورق waraq, which means a leaf, paper.
