Title	Research on the Variation of Nitrite Content of Toona Sinensis and the Technology to Reduce Nitrite Content
Abstract	Toona sinensis belongs to Meliaceae, Toona Roem. Its Latin name is Toona sinensis (A.Juss.) Roem. It is a plant species that grows particularly in China. Toona shoots contain numerous nutrients. According to the research of China Medical & Science Academy, every 100 g of toona contains 9.8 g of protein, which is the highest protein content among vegetables. Toona also bears significant value as food and medicine. Toona wood is a kind of precious limber。Recent research revealed that there is a significant amount of nitrite in toona. Nitrite is a chemical that can cause damage to human health. The intake of too much nitrite may cause dyspnea, circulatory failure and central lesion. It may be fatal in extreme cases.In the study, we chose red toona leaves obtained from Jinan toona base and market as the research object. The research is aimed at studying the distribution of nitrite in toona and developing efficient technology to decrease the nitrite content in toona so as to provide technique guidance and theological evidence for the manufacture of low nitrite toona products. It also offers scientific basis for the cultivation of toona plants to achieve the objective of improving the quality of toona products and guaranteeing customer health.By comparing the nitrite contents of toona leaves with different lengths, we discovered that 54.5% of the toona plants studied have long toona leaves with lower nitrite content compared with shorter leaves. Regarding the nitrite contents in toona leaves positioned at the top and the middle of the tree, there are differences among individuals.The toona samples are treated by methods of soaking in oxidizer or reductase solutions and hot water. Different solution concentrations and soaking durations have been set. The variation of nitrite content was determined by measuring the nitrite content before and after the toona samples were treated. The vitamin C content was measured simultaneously to determine the nutrient losses caused by the soaking treatment. The oxidizer or reductase solutions and hot water soaking treatments were conducted separately to determine the optimal concentrations and durations. The two methods were further combined using the concentrations and durations chosen and measurements of nitrite and vitamin C were conducted to determine the variations of nitrite and vitamin C contents. The result reveals that for the treatments only using oxygen or reductase, the solution chosen with optimal nitrite reducing effects are 13% sodium carbonate solution,2% glucose solution,0.5% Vitamin C solution and 0.03mol/L hydrogen peroxide. For the hot water treatments, the optimal time lengths are 5s and 30s when taking into consideration both the nitrite reduction and Vitamin C losses. For the treatments using combined methods, soaking in 2% sodium carbonate solutions for 5s and in 13% glucose solution for 5s have the optimal nitrite reducing effects.The toona samples which have been treated to decrease nitrite content were frozen and pickled separately. The measurement of nitrite content was conducted every 30 days to observe the fluctuation of nitrite content. The measurement of vitamin C content was conducted every 60 days to observe the fluctuation of nutrients. The results reveal that the nitrite and vitamin C content in frozen toona maintained at a relatively low level during the storage with slight fluctuation The nitrite and vitamin C content in pickled toona have seen a sharp decrease.The measurement of essential oil content in toona samples which have been treated to decrease nitrite content was conducted using GC analysis technology. The results reveal that the decrease of nitrite content in toona was followed by the decrease of essential oil content. The treated toona samples which have low nitrite content bear low essential oil content.The technology combined to decrease nitrite content efficiently decreases the nitrite content in toona samples. It provides technology support and theological evidence for the research and manufacturing of toona products with low nitrite content.

Chinese-toona: Chinese-toona

I’m excited to introduce Chinese Toon. Before this post, I only knew this vegetable/herb by its Chinese name. I have never seen it sold or grown in the U.S. as pictured; only in its dried form and even that is rare. In fact, I didn’t even know what this looked like until a family friend gave us a batch from her garden. It was an exciting day.

Imagine growing up eating and loving cilantro, but not knowing its name or what it looked like. That’s how I feel about xiang chun.  It has a strong distinct flavor with a similar strength as garlic. It can be a great complement to a dish or overwhelming if you don’t like the taste (similar to onion or chives). I can eat it with everything!

It is predominately used in Asian cuisine, mainly Chinese. I have had it with tofu, eggs, stir-fries, noodles, rice and savory Chinese pancakes. All delicious!

To Prepare:

Step 1: fold the leaves in half and tear them off the branch from the stem (this will leave the root behind)

Step 2: after washing, mince leaves

Step 3: transfer to container, sprinkle salt to bring out juices, mix and seal (the true flavor of xiang chun will not come out till this step)

You can then save this for future use in tofu, stir-fries, noodles, fried rice or pancakes.

Next time you come across Toona sinensis aka Chinese Toon or 香椿 xiang chun, you’ll know how to use it or at least have a new dish to try at your favorite Chinese restaurant. Be sure to ask for it in its Chinese name, xiang chun. Here’s the wiki page to learn more.

Enjoy!

DR. CALI KHALIIF GALEYR: “Cidda oraneysa afraad baa ku shireysa Taleex waa ka been sheegeysaa xaqiiqda, waagaa baryayna nin gacan weyn iyo nin gacan yar toona ma qarin karo”

Axad, January 15, 2012(Idhanka): Ra’iisal Wasaarihii hore ee Soomaaliya Dr. Cali Khaliif Galeyr oo  Degmada Taleex ee gobolka Sool uga qeybgelaya  Shirka Khaatumo II ayaa wareysi uu siiyay Laanta Afka Soomaaliga ee VOA-da (Halkaan ka dhageyso)  waxaa uu uga hadlay arrimo dhowr ah oo ku saabsan shirkaas Taleex iyo sida uu u arkayo fal-celin uu shirkaas ka keenay Madaxweynaha Somaliland Axmed Maxamed Maxamuud Siilaanyo oo sheegay in ay shirkaas ka qeybgaleen afraad fidno-wadayaal ah.

Dr. Cali Khaliif Galeyr ayaa nasiib darro ku tilmaamay in sida uu u yiri Axmed Siilaanyo uu sheegay in ay Taleex ku shireen afraad ama shakhsiyaad, wuxuuna caddeeyay in ay shirkaas qabsadeen dadka u dhashay Sool, Sanaag iyo Cayn “Waxaa nasiib darro ah in Maxamed Maxamuud Siilaanyo oo diidanaa xukunka xukuumaddii hore oo lahaa xuquuqda dadkeyga ayaa lagu xad-gudbayaa in uu maanta yiraahdo waan diidanahay dadka Sool, Sanaag iyo Cayn in ay aayahooda ka tashadaan”ayuu yiri Dr. Cali Khaliif Galeyr oo caddeeyay in ay si weyn u raddinayaan hadalka uu sheegay Madaxweynaha Somaliland Axmed Siilaanyo.

Waxaa la weydiiyay hadalkiisa in uu u dhacayo in Beesha degta Sool oo shirkii gooni-isu-taagga Somaliland ka qeybgashay ay haatan gebi ahaanba ka baxday heshiiskii lagu dhisay Somaliland, wuxuuna sheegay in uu isago Cali Khaliif ahaan ka qeybgalay labo shir oo arrimhaas looga hadlayay, “Shirarkii 1991 (Burco) iyo 1993-kii (Boorama) labadaba waan ka qeybgalay aniga Cali ahaan, markii hore ee 1991-kii caqli badan in uu meesha yaallo nooma muuqan, waxaa noo muuqatay in hub badan oo Qaranka hubkiisii ahaa in uu gacanta u galay SNM, markaa waxaa noo muuqatay in iyadoo la siman yahay oo cidina aysan cid qasbaneynin wax la xalilo, waxaanu dan moodnay in loo talo badsado, arrin soo jireen ah ma ahayn, arrin ugub ah ayay ahayd, waddanka ayaa la kala goynayaa markaas kuma qanacsaneyn, 20-kii sano kuma qanacsaneyn, maantana kuma qanacsanin”ayuu yiri Dr. Cali Khaliif Galeyr oo sheegay in dadka Sool, Sanaag iyo Cayn u dhashay aysan ogoleyn in dalka Soomaaliya la kala gooyo.

Waxaa uu xusay Dr. Cali Khaliif Galeyr in shirka Khaatumo II looga hadlayay arrimaha dadka u dhashay Gobollada Sool, Sanaag iyo Cayn, isla markaana ugu dambeynta laga soo saari doono maamul madax bannaan oo ay dadka gobolladaas yeeshaan”Arrimaha maamulkaas ku dhawaaqiddiisa gacanta ayaa lagu hayaa, dhaqsina waa loogu dhawaaqi doonaa, cid ka hor-imaan karta oo waagaa baryay iyo qorraxdaa soo baxday gacanta ku celinta kartana ma jirto”ayuu yiri Dr. Cali Khaliif.

Deegaannada uu maamulka lagu dhisayo Taleex ka talin doono haddii lagu dhawaaqo ayaa la weydiiyay Dr. Cali Khaliif Galeyr, wuxuuna sheegay in dhulka uu ka talin doono ay yihiin Sool, Sanaag iyo Cayn, “ Dhulka ay dadkan leeyihiin waa la yaqaan, meelaha la wada degan yahayna waa la yaqaan, u maleyn maayo Siilaanyo in uu Laascaanood ku murmayo ama dhulka SSC ee aan taariikhiyan leenahay, haddii uu taas ka murmana dee isagaa cirka roob ku og” ayuu yiri Dr. Cali Khaliif.

Deegaannadaas oo ay hadda gacanta ku hayaan Ciidamada Somaliland sida ay qorsheynayaan in ay ku soo ceshadaan ayaa la sii weydiiyay Dr. Galeyr, wuxuuna ku jawaabay “Annaga waxaan u dhabar adeegeynaa in si nabadgelyo ah arrimahaas ku dhammaadaan ku dhamaadaan, ciidamada Somaliland ee halkaas joogana ay meesha ka baxaan, iyadoo aanan la is-qasbeynin, iyadoo aan ognahay in ay jiraan waxyaabo badan oo aan wada leenahay taariikhiyan, haddana aan diyaar u nahay in wixii aan wada leenahay wada hadal lagu galo”.

Waxaa la weydiiyay Dr. Galeyr sida ay u arkayaan dadka ka soo jeeda gobollada Sool, Sanaag iyo Cayn ee ka tirsan maamullada Somaliland iyo Puntland, wuxuuna sheegay in dadkaas ay u arkayaan sida uu maamulka Somaliland u arkayo dadka Hargeysa u dhashay ee ka tirsan Dowladda Soomaaliya ee fadhigeedu yahay.

“Cidda oraneysa afraad baan ku shireysa Taleex waa ka been sheegeysaa xaqiiqda, waayo halkan (Taleex) waxaa isugu yimid dhammaan dadka u dhashay dhulkan oo Isimadii, Cuqaashii, Culumaa’udiinkii, Siyaasiyiintii, Ganacsatadii, Haweenkii iyo cid walba ah, cidda caga jugleyneysana u suurtagelimeyso waxa ay dooneyso”ayuu Dr. Cali Khaliif Galeyr.

“Maamullada Somaliland iyo Puntland waa ay diidan yihiin maamulka laga filayo Shirka Khaatumo II, markaas waa tee cidda aad isku halleyneysaan ayay ahayd su’aal kale oo la weydiiyay Dr. Cali Khaliif Galeyr, “taageerada aan heysanno waa tan dadkeena, 100%  dadku meel ayay uga soo wada jeedaan, awooddeena baana ku tashaneynaa”ayuu yiri Dr. Galeyr.

Haddii colaad uu horseedo shirkan Taleex oo deegaanno nabad ah ay colaad ka dhacdo cidda mas’uuliyaddaas qaadeysa ayaa la weydiiyay Dr. Galeyr, wuxuuna sheegay in aysan jirin nabad taalla Sool, Sanaag iyo Cayn, “Ma Laascaanood baa nabadi taallaa, bandow baa ka jira, 5ta galabnimo ayaa la xiraa, Ardaydii baa la leynayaa, ma ogolin dhaqan-xumada lagu hayo Laascaanood, ma ogolin wixii ka dhacay Kalshaale iyo Hoodaale”ayuu hadalkiisa ku sii daray Dr. Cali Khaliif Galeyr oo sheegay in aysan weerar ku ahayn Burco, Berbera iyo Hargeysa.

Su’aal kale oo la weydiiyay Dr. Galeyr ayaa ahayd cidda ay Isbaheysi la sameysan doonaan haddii ay Somaliland iyo Puntland ay dhismaha maamulkooda diidan yihiin, “Shirweynaha Soomaaliyeed ayaan xiriir la sameysaneynaa, welina kama quusan shacbiga Somaliland iyo Puntland oo dano ayaan wada leenahay, maamulladana waan aragnaa. Maamulka Somaliland waxa uu diidan yahay oo aan u cuntameynin waxaa weeye annagu waxaan rabnaa midnimada Soomaaliyeed, haddii uu maamulka Somaliland leeyahay Annaga Soomaaliya kama mid noqoneyno  iyaga ayay u taallaa, waxaanse aragnay in Umadda dhulkan ku nool iyo Umadda Soomaaliyeedba guud ahaan in ay danta ku jirto in aan dalkan la kala gooyn, balse laga tashado sidii la isugu soo noqon lahaa iyo sidii wax loo qeybsan lahaa habkii ay doontaba ha noqotee”.

Chinese-toona

I’m excited to introduce Chinese Toon. Before this post, I only knew this vegetable/herb by its Chinese name. I have never seen it sold or grown in the U.S. as pictured; only in its dried form and even that is rare. In fact, I didn’t even know what this looked like until a family friend gave us a batch from her garden. It was an exciting day.

Imagine growing up eating and loving cilantro, but not knowing its name or what it looked like. That’s how I feel about xiang chun.  It has a strong distinct flavor with a similar strength as garlic. It can be a great complement to a dish or overwhelming if you don’t like the taste (similar to onion or chives). I can eat it with everything!

It is predominately used in Asian cuisine, mainly Chinese. I have had it with tofu, eggs, stir-fries, noodles, rice and savory Chinese pancakes. All delicious!

To Prepare:

Step 1: fold the leaves in half and tear them off the branch from the stem (this will leave the root behind)

Step 2: after washing, mince leaves

Step 3: transfer to container, sprinkle salt to bring out juices, mix and seal (the true flavor of xiang chun will not come out till this step)

You can then save this for future use in tofu, stir-fries, noodles, fried rice or pancakes.

Next time you come across Toona sinensis aka Chinese Toon or 香椿 xiang chun, you’ll know how to use it or at least have a new dish to try at your favorite Chinese restaurant. Be sure to ask for it in its Chinese name, xiang chun. Here’s the wiki page to learn more.
