Zinthu zachilengedwe zimapezeka kwambiri mu zipatso, mizu, zimayambira, ndi masamba a mbewu mu pectin, pectin, ndi pectic acid, ndipo ndi gawo la khoma la cell. Protopectin ndi chinthu chomwe chimakhala chopanda m'madzi, koma chitha kusinthika ndikusinthidwa kukhala pectin yosungunuka madzi pansi pa acid, alkali, mchere ndi ma enzymes ndi michere ina.

Pectin makamaka ndi mzere polysaccharide polymer. D-Galacturonic acid ndiye gawo lalikulu la mamolekyu peleti. Unyolo waukulu wa ma pectin mamolekyu amapangidwa ndi D-Galactopy Ranosyluronic acid ndi í. -1,4 glycosidic (α-1, 4 glycosidic) amapangidwa, ndipo magulu ambiri a carboxyl pa galacturonic acid c6 ilipo mawonekedwe a methyted.

Maudindo a Peckin m'matumbo

1. Sinthani mawonekedwe ndi maswiti a maswiti

2.Pewn ali ndi bata bwino pakuphika

3.Kutulutsidwa ndi kwachilengedwe

4, kapangidwe kaswiti ndikosavuta kuwongolera (kuchokera ku zofewa mpaka kolimba)

6. Magwiridwe antchito abwino kuti akweze mtima

7. Okhazikika ndi Curlable gel katundu ndi mitundu ina yazakudya

8. Kuyanika sikofunikira
