Bamboo shoots or bamboo sprouts are the edible shoots (new bamboo culms that come out of the ground) of many bamboo species including Bambusa vulgaris and Phyllostachys edulis. They are used as vegetables in numerous Asian dishes and broths. They are sold in various processed shapes and are available in fresh,dried,and canned versions.
Raw bamboo shoots contain cyanogenic glycosides,natural toxins also contained in cassava.[3] The toxins must be destroyed by thorough cooking,and for this reason,fresh bamboo shoots are boiled before being used in other ways. The toxins are also destroyed in the canning process.
Harvested species
Most young bamboo shoots are edible after being boiled to remove toxins,[4] but only around a hundred or so species are harvested regularly for edible shoots. These are usually from species that are also cultivated for other uses. These include:[5][6][7][8][9]
Bambusa –the most commonly harvested bamboo in tropical and subtropical Asia,occurring from the Philippines to India,and from Sumatra to southern China.
Freshly collected bamboo shoots are a good source of thiamine,niacin,vitamin A,vitamin B6,and vitamin E. 17 different amino acids have been reported,8 of them essential for humans. The amount of amino acids in canned and fermented shoots is lower than when freshly prepared.[11]
Raw bamboo is toxic to humans,containing cyanide compounds,hence it is always boiled when used for human consumption.[3] The diet of giant pandas and red pandas is largely made up of raw bamboo;the animals' body tissue is not well able to detoxify cyanide,but their gut microbiomes are significantly enriched in putative genes coding for enzymes related to cyanide degradation,suggesting that they have cyanide-digesting gut microbes.[12]
East Asia
In certain parts of Japan,China,and Taiwan,shoots from the giant timber bamboo Bambusa oldhamii are harvested in spring or early summer. Young shoots from this species are highly sought-after due to their crisp texture and sweet taste.[13] Older shoots,however,have an acrid flavor and should be sliced thin and boiled in a large volume of water several times. The sliced bamboo is edible after boiling. B. oldhamii is more widely known as a noninvasive landscaping bamboo.
Pickled bamboo,used as a condiment,may also be made from the pith of the young shoots. In Japan,menma is a common topping for ramen noodle soup. In China,luosifen river snail noodles,a popular dish from Guangxi,get their famously pungent smell from pickled bamboo shoots.[14]
South Asia
In Nepal,they are used in dishes that have been well known in the country for centuries. A popular dish is tama (fermented bamboo shoot),made with potato and beans. An old popular song in Nepali mentions tama as "my mother loves vegetable of recipe containing potato,beans,and tama". Some varieties of bamboo shoots commonly grown in the Sikkim Himalayas of India are Dendrocalamus hamiltonii,Dendrocalamus sikkimensis and Bambusa tulda locally known as choya bans,bhalu bans and karati bans. These are edible when young. These bamboo shoots are collected,defoliated and boiled in water with turmeric powder for 10–15 minutes to remove the bitter taste of the bamboo after which the tama is ready for consumption. Tama is commonly sold in local markets during the months of June to September when young bamboo shoots sprout.
In Assam,bamboo shoot is called bah gaj in Assamese and hen-up in Karbi. It is an integral part of traditional Assamese cuisine. Fermented bamboo shoot,called khorisa, is a widely used ingredient in Assamese recipes for meats such as pork,chicken,duck and squab or pigeon. Fermentation increases the nutritional value of bamboo shoots by making some nutrients more bioavailable and degrading toxins.[15]
In Karnataka,Andhra Pradesh,and Northern Tamilnadu,the bamboo shoots are used as a special dish during the monsoons (due to seasonal availability). It is common in Tulunadu and Malnad regions. It goes by the name kanile or 'kalale in Tulu,Veduru Kommulu in Telugu,and Moongil Kuruthu in Tamil. The shoots are usually sliced and soaked in water for two to three days,after which the water is drained and replenished each day to extricate and remove toxins. It is also used as a pickle. It is consumed as a delicacy by all communities in the region. [citation needed]
In the Diyun region of Arunachal Pradesh,the Chakma people call them bashchuri. The fermented version is called medukkeye and is often served fried with pork. The bamboo shoots can also be fermented and stored with vinegar.[citation needed]
In Jharkhand,India,the bamboo shoots are used as a vegetable. Young shoots and stored shoots are known as karil and shandhna respectively.[16]
In the western part of Odisha,India,they are known as karadi and are used in traditional curries such as Ambila,pithou bhaja and pickle. In monsoon,it can be abundantly found in Bamboo forest of Karlapat wildlife sanctuary and mostly prepared in homes using mustard paste. They can be stored for months in an air tight container. They are also dried in sun increasing their shelf life and these dried shoots are called Hendua. The dried shoots are used in curries of roasted fish,called Poda Macha.[citation needed]
In Nagaland,India,bamboo shoots are both cooked and eaten as a fresh food item or fermented for a variety of culinary uses. Fermented bamboo shoot is commonly known as bas tenga. Cooking pork with a generous portion of fermented bamboo shoot is very popular in Naga cuisine. [citation needed]
In Manipur,India,they are known as u-soi. They are also fermented and preserved after which they are known as soibum. They are used in a wide variety of dishes –among which are iromba,ooti and kangshu etc.[17] The fermented bamboo shoot which is preserved for many months is known as soijin. Soijin can be stored up to 10 years in Andro village. Generally,soijin or usoi is in a big basket made of bamboo. However,they are stored in earthen pot in Andro village.
In Meghalaya,bamboo shoots are either used fresh or fermented and made into pickles,soups with pork or dried fish,or curried and seasoned with sesame seeds or made into a sauce with fermented fish. It sometimes cooked along with yam leaves and dried fish.
In Chittagong Hill Tracts,Bangladesh,bamboo shoots are a traditional food of the indigenous Jumma people. The preparation of their dishes consist of several steps. First,bamboo shoots are collected from the bamboo forest then defoliated and boiled in water. Afterwards,the bamboo shoot is prepared with shrimp paste,chili,garlic paste,and salt.[citation needed]
In the Philippines,bamboo shoots are primarily harvested from bolo bamboo (Gigantochloa levis),giant bamboo (Dendrocalamus asper),common bamboo (Bambusa vulgaris),spiny bamboo (Bambusa blumeana),and two endemic species,bayog (Bambusa merrilliana) and laak (Bambusa philippinensis). Other economically important species also harvested for bamboo shoots include kayali (Gigantochloa atter),male bamboo (Dendrocalamus strictus),and climbing bamboos (Dinochloa spp.) Another endemic species,the lumampao or bagakay bamboo (Schizostachyum lumampao),which are used for making sawali (woven bamboo strips),are also occasionally harvested for bamboo shoots.[10] In Filipino cuisine,the shoots are commonly called labóng (other names include rabong,dabong,or tambo). The two most popular dishes for these are ginataáng labóng (shoots in coconut milk and chilies) and dinengdeng na labóng (shoots in fish bagoóng and stew of string beans,saluyot,and tinapa). They are also sautéed alone or with other ingredients as in paklay,or cooked as fried or fresh lumpia. Bamboo shoots are also preserved as atchara,traditional sweet pickles that are often made from papaya.[18][19]
Yam no mai,a northern Thai salad made with boiled bamboo shoots
In Thai cuisine bamboo shoots are called no mai. It can be used in stir-fries,soups such as tom kha kai,curries such as kaeng tai pla,as well as in salads such as sup no-mai. Some dishes ask for fresh bamboo shoots,others for pickled bamboo shoots (no mai dong).[20]
In Vietnamese cuisine,shredded bamboo shoots are used alone or with other vegetable in many stir-fried vegetable dishes. It may also be used as the sole vegetable ingredient in pork chop soup. Duck and bamboo shoot noodles (Bún măng vịt)[21] is also a famous noodle dish in Vietnam.
In Myanmar,bamboo shoots are called hmyit (Burmese:မျှစ်). They can be used in a soup called myahait hcaut tar la bot or talabaw,bamboo soup. The preparation of this dish generally follows three steps. First,the bamboo shoots are collected from a bamboo forest. Bamboo can be found in the whole of Myanmar but the bamboo shoots from the two northernmost regions (Kachin State and Sagaing Region) are soft and good in taste. The bamboo shoots are then boiled in water after which they can be cooked with curry powder,rice powder,and other ingredients such as snakehead fish and basil leaves. A small amount of rice and some shreds of meat or seafood may also be added.[22][23][24][25] The soup was traditionally used by the Karen people as a supplement to rice,which was not readily or cheaply available to them.[26] Talabaw is one of the most well known soups in Myanmar,and widely considered to be the essential dish of Karen cuisine.[26] Another bamboo shoot dish in Burmese cuisine is a sour bamboo shoot curry called hmyit chin hin (မျှစ်ချဉ်ဟင်း),a specialty of Naypyidaw in central Burma.[27]
In Indonesia,they are sliced thinly to be boiled with coconut milk and spices to make gulai rebung. Other recipes using bamboo shoots are sayur lodeh (mixed vegetables in coconut milk) and lun pia (sometimes written lumpia:fried wrapped bamboo shoots with vegetables). The shoots of some species contain cyanide that must be leached or boiled out before they can be eaten safely. Slicing the bamboo shoots thinly assists in this leaching.[citation needed]
Ethiopia
Bamboo shoots are also eaten in Ethiopia. The locations where bamboo grows are not contiguous. Bamboo shoots of O. abyssinica are eaten in lowland locations of Pawe,Assosa and Bambasi districts of Benishangul Gumuz Regional State and in Sinan Wereda of Amhara Regional State.[28][29]
Bamboo shoots of A. alpina are also eaten in higher elevations,including from two bamboo forests about 80 km. apart,both areas at higher elevations than the surrounding land.[30][29] One is on a mountain south of Mizan Teferi,the other is on the higher elevations near Maasha,between the cities of Tepi and Gore.
