Ulwati, olunye lokudla. Lunamandla okudiliza imithambo, lapho ulwandle lubhakiwe, lunokuthambisa okungapheli, luncibilika emlonyeni, ikakhulukazi ngemva kokulungiswa ngezinongo, kwengezwe amafutha, usawoti nezinye izinongo, lube yisimo esihlwabusayo esithi "ulwandle". Ulwandle luhlanganisa amavithamini ahlukahlukene e-B ku-ulwandle, ikakhulukazi i-riboflavin ne-niacin, futhi lunothe nge-vitamin A ne-vitamin E, kanye ne-vitamin C encane. Ulwandle luqukethe cishe u-15% wamaminerali, okubalulekile ekugcineni imisebenzi evamile yomzimba njenge-potassium, i-calcium, i-magnesium, i-phosphorus, i-iron, i-zinc, i-copper, i-manganese, njll., okuhlanganisa i-selenium ne-iodine, la maminerali angasiza umzimba ukuthi ugcine ibhalansi ye-acid-base, kuthuthukise ukukhula kwezingane, futhi kusize abadala ukubambezela ukuguga.

Ulwati lugcwele ulwandle; kodwa ulwandle akulona lonke ulwandle. I-Rhodophyta, umndeni we-Ceramiaceae. Umzimba we-algae unombala onsundu noma obomvu, wakhiwe umugqa owodwa noma imigqa emibili yamangqamuzana, unamafomu ahlukahlukene njengomumo weqabunga, umumo wenhliziyo, nomumo webhande. Isisekelo esifana nezinwele esingezansi kolwandle siyanamathela ematsheni. Singafinyelela ku-20-30 cm ubude. Izinhlobo zocansi ezihlukene, inqubo yokuzala iyinkimbinkimbi kakhulu. Ngo-1955, ososayensi baseShayina baqala ukuqonda ngokugcwele umjikelezo wokuphila wolwandle, okwakhiwa izigaba ezintathu: ulwandle, i-filament, nolwandle oluncane. Izithako eziyinhloko zolwandle zihlanganisa cishe u-50% wama-carbohydrate, cishe u-30% wamaprotheni aluhlaza, amavithamini A, B, C anothe, futhi aqukethe i-iodine, i-phosphorus, i-calcium, njll. Kuyinto evamile yaseShayina, futhi itholakala emingceleni yolwandle yaseShayina, ikakhulukazi emingceleni yolwandle yaseJiangsu. Kunezinhlobo ezimbili zolwandle ezithengiswa emakethe: eyodwa i-nori eyosiwe (ulwandle olubhakwe) esetshenziselwa ukwenza ama-sushi rolls, enye ibizwa ngokuthi "ulwandle olunongwe ngokushesha", zombili zisebenzisa i-Pyropia yezeri njengesithako esiyinhloko.
