Tannins (tannins) makomisheni anowanzo gadzirwa nemiti. Iwo ndeepolyphenols uye ane reactive makomisheni. Tannins inonyungudika mumvura uye ine huremu hwemamorekuru muhupamhi hwe500 kusvika 3000 Da. Zvigadzirwa zvine huwandu hwehuwandu hwemakomponi aya zvine hasha, isingafadzi kuravira uye inogona kuve ine chepfu.
Panyaya yezvirimwa, maTannins ane basa rekudzivirira, kudzivirira herbivores. Pakati pezvimwe zvinhu, tannins iripo mumakwati emuoki, willow, spruce, chestnut, larch, walnut mashizha, sage, waini, tei, nzungu, mumichero yakawanda (yakadai seblueberries, sitirobheri, raspberries, cranberries, mazambiringa, mapomegranati, maapuro), muSt. wort, cinquefoil, turnip rape, cistus infusion uye legume mbeu, buckwheat, chokoreti yakasviba uye cocoa.
Tannins - kuparara
Isu tinoparadzanisa tannins mumhando mbiri:
- hydrolysing - pakati pemamorekuru ine monosaccharide, iyo hydroxyl mapoka ayo anosimbiswa ne gallic acid zvakasara kana zvinobva zvaro; zviri nyore hydrolysed kune asina kusimba asidhi uye mabhesi kana ma enzymes;
- kwete-hydrolysing (yakanyungudutswa) - haina saccharide mu molecule, inowanikwa mumichero isina kuibva uye mbeu, iyo pasi pesimba rekuibva inoputsika kuita makemikari ane maduku maduku.
Tannins - zvinhu
Tannins inoratidzirwa nezvinhu zvakawanda zvinobatsira kumuviri wemunhu, kusanganisira:
- bvisa marwadzo,
- kuderedza kuvaviwa uye kupisa,
- vane anti-inflammatory uye antibacterial properties,
- tsigira basa re immune system,
- kudzivirira allergies.
Kutorwa nemuromo, vane astringent mhedzisiro pa mucous membranes, inhibit permeability yavo, kudzivirira, semuenzaniso, microbleeding kubva mumidziyo yeropa yecapillary (kunyanya mudumbu remudumbu).
Maererano nemasayendisiti, tannins inogona kudzivirira kumarudzi ose tumoruye zvakare kuderedza chiyero icho masero ekenza anokamura. Vanogona kubatsira kugadzirisa microflora yemuromo uye mumatumbo, kubvisa pathogenic organisms. Yakasimba antioxidant zvimiro zvetannins inoderedza mahara radicals anokuvadza ekutanga maseru zvimiro. Vanodzivisa lipid peroxidation uye kuwanda kweHIV. Ivo zvakare vane anti-carcinogenic effect. Zviri nyore hydrolysing tannins yakaputsika mudumbu rekudya. Tannins inoshandiswawo kurwisa mhedzisiro yealkaloids chepfu.
Tannins inoshandiswawo kurapa ganda remhuka. Iyo antioxidant basa retannins yakakoshawo mukuwedzera hupenyu hwesherufu yechikafu. Muenzaniso iwaini tsvuku, iyo, nekuda kwetannins, inogona kukura kwemakore akawanda uye haina oxidized. Nekuda kwekureruka kwekubatanidza tannins nesimbi ions, anoshandiswa kuwana dhayi.
Kunyanya kushandiswa kwezvirimwa zvakapfuma mu tannins kunodzivisa kubatwa kwe, pakati pezvimwe, mavitamini, macro- uye microelements mumugwagwa wegumbo. Non-hydrolysing tannins inoora mudumbu remukati muzvikamu zvine chepfu, zvichikonzera chepfu, saka kudya michero isina kuibva kunofanira kudziviswa.
