Khansara ya Mtsinje ndi mitundu ya banja la decapod crustaceans ya order Astacidea. Thupi la khansa liri ndi:
- The cephalothorax, yomwe ili ndi magawo awiri: anterior (mutu) ndi posterior (thoracic), kuphatikiza pamodzi. Pamutu pamutu pali msana wakuthwa. M'mphepete mwake mumtunda wake mumayambira pamakhala maso. Kutsogolo kwa khansara yamtsinje pali awiri awiri awiri a tiyi tochepa, pakati pake ndi yayitali.
- Mimba yamtundu, yogawidwa, yokhala ndi magawo 7. Mimba ya khansara ili ndi mapaipi asanu ndi awiri omwe amagwiritsa ntchito madzi osambira. Mapaundi asanu ndi limodzi ndi asanu ndi awiri ndi asanu ndi awiri a miyendo amapanga caudal.
Zida zankhondo zamadzi amadzipangira chitetezo ndi kuzunzidwa. Mayi ali aang'ono kuposa amuna ndipo magawo a mimba ali ochuluka kwambiri kuposa cephalothorax. Amuna ali ndi mizere yamphamvu kwambiri. Ngati khansara ya mtsinje imataya nthambi, ndiye kuti mutatha kuyenga, idzakula nthambi yatsopano m'malo mwake. Mtundu wa nsomba zazingwezi zimatha kusiyana chifukwa cha madzi ndi malo. Kawirikawiri, khansa yamtsinje ili ndi mtundu wobiriwira, wobiriwira, wobiriwira kapena wabuluu.
Madzi amchere amapezeka m'madzi atsopano ku Ulaya. Mtembo uwu umapezeka m'madzi abwino oyera: m'mitsinje, m'nyanja, m'madziwe, m'mitsinje yofulumira kapena yothamanga (mpaka mamita 5 kuya, ndi kutaya mpaka mamita 12). Khansara ya mtsinje imapita ku kusaka usiku wokha. Masana, amalowa m'nyumba zosiyanasiyana - pansi pa mizu, miyala, mitsempha ndi zinthu zina zomwe zingagone pansi. Amatetezera malo ake okhala ndi crayfish zina. Madzi amchere amatha kukumba mzere wa masentimita 35. Mu chilimwe, nsomba za nsomba zimakhala m'madzi osaya, ndipo m'nyengo yozizira - zimapita mozama mu nthaka, dothi kapena mchenga.
Monga munthu, nkhanu za mtsinje zakhala zikugwiritsidwa ntchito kuyambira kale. Izi zimatsimikiziridwa ndi zotsalira za zipolopolo za nyama zomwe zimapezeka mu "milu ya khitchini" ya nyengo ya Neolithic. Asanayambe kutumikira, madzi amtunduwu amasinthidwa ndi madzi otentha mumadzi amchere, kupeza pambuyo pa utoto wofiira komanso fungo losangalatsa. Zakudya zophika nsomba zotsekedwa zimatumizidwira patebulo lowazidwa ndi zitsamba (parsley, celery, katsabola, etc.).
Mtundu wa nsomba zazing'onoting'ono pakuphika ukufotokozedwa ndi kuchuluka kwa carotenoids mwa iwo. Khungu limakhala ndi Astaxanthin, yomwe imakhala yofiira kwambiri. Asanayambe kutentha kwa ziweto zamoyo zamtundu wa crustaceans, carotenoids imaphatikizidwa ndi mapuloteni, choncho mtundu wa madzi otsekemera ndi mtundu wa bluu, wobiriwira kapena wofiirira. Nthawi yotentha, mankhwalawa amatha, ndipo kumasulidwa kwa astaxanthin pigment kumapereka thupi lofiira.
Musanayambe kudula nsomba za nsombazi, muyenera kuphika pang'ono m'madzi otentha, kuti nyamayo ikhale yosiyana kwambiri ndi chipolopolocho.
Zofunikira za khansa ya mtsinje:
Nyama yochuluka kwambiri ya khansa yamtsinje imapezeka m'mimba ndi m'mizere. Vuto lalikulu likupezeka m'mimba.
Nyama ya khansara yamtsinje imakhala yoyera, ndipo imakhala ndi mitsempha yosavuta ya pinki. Ndiwopatsa thanzi komanso yabwino kwambiri. M'mawonekedwe ake, nyama ya khansara ili ndi mapuloteni ambiri komanso mafuta ochepa. Nyama ya nyama imeneyi imatanthawuza zakudya zabwino kwambiri ndi zakudya zokoma, zomwe zimapangidwanso mosavuta ndipo zimakhala ndi zinthu zambiri zothandiza. Izi zikuphatikizapo: mapuloteni (mpaka 16%), calcium, mavitamini E ndi B12. Nkhuku za nkhono za mtsinje zili ndi cholesterol ndi mafuta, komanso mafuta.
Inde, khansara ya mtsinje sichiwerengero cha nyama yomwe imakhala mkati mwake poyerekeza ndi mabanja ena amchere a anthu omwe amagwiritsa ntchito madzi osokoneza bongo omwe anthu amagwiritsa ntchito kuti adye. Kwa akulu, pali nyama yaying'ono. Mwachitsanzo, mu kilogalamu ya shrimp muli pafupifupi magalamu 400 a nyama, ndi kilogalamu ya kansomba - pafupifupi 100-150 magalamu. Pa nthawi yomweyi, nsomba zazing'ono za mtsinje zimakhala zokwera mtengo kwambiri kuposa ma shrimps. Mwinanso, kugwiritsa ntchito nsomba zazingwezi kumachokera ku maonekedwe okongola a mbale zomwe amakometsera.
Maonekedwe a nyama ya khansara yamtsinje ali ndi sulfa yambiri, choncho sayenera kusungidwa mu aluminium cookware. Mutatha kuyanjana ndi zitsulo, nyama imatembenuka wakuda ndi zofunkha. Ndibwino kuti mugwiritse ntchito magalasi.
