Kodi Agar Agar ndi chiyani?
Agar agar (nthawi zambiri imangokhala "agar") ndihydrocolloid yochokera ku zomerayotengedwa kuchokera ku nsomba zofiira za m'nyanja (Rhodophyta). Ndi polysaccharide yopangidwa m'makoma a selo la nsomba, yokonzedwa kukhala ufa, zipolopolo, kapena mipiringidzo. Chifukwa imachokera ku nsomba za m'nyanja, agar ndi yachilengedweosadya nyama, osadya nyama, ndi halal/kosher mwachisawawa — ubwino waukulu wa mitundu ya zinthu zochokera ku zomera.
Malinga ndi mankhwala, agar ndi gulu la agarose ndi agaropectin. Imakhala gel yolimba komanso yophwanyika pamlingo wochepa kwambiri (nthawi zambiri 0.5–1.0%) ndipo, chofunika kwambiri,imasungunuka pa 80–90 °C — pamwamba pa kutentha kwa thupi. Ichi ndichifukwa chake zinthu zopangidwa ndi agar zimasunga mawonekedwe awo kutentha kwa chipinda ndipo sizimasungunuka mkamwa.(Pang et al., 2020).
Agar yogulitsa imagulitsidwa ngati ufa, ma flakes, kapena mipiringidzo, ndipo imafunika kuwiritsa (95–100 °C) kuti isungunuke kwathunthu isanayambe kuzizira — mosiyana ndi gelatin, yomwe imanyowetsa ndikusungunuka m'madzi ofunda. Chifukwa zokolola za m'nyanja zimasiyana malinga ndi nyengo ndi dera, mtengo ndi kupezeka kwa agar zimatha kusinthasintha kuposa mitsinje ya gelatin yochokera ku ziweto, chinthu chofunikira kwambiri kwa ogula ambiri.
Kodi Gelatin Yodyedwa Ndi Chiyani? (Chidule Chachidule)
Gelatin wodyedwandimapuloteniyochokera ku hydrolysis pang'ono ya kolajeni ya nyama (zikopa za ng'ombe, zikopa za nkhumba, kapena mafupa). ImapangaMa gels osinthika omwe amasungunuka pafupi ndi kutentha kwa thupi (~35 °C), zomwe zimapatsa zakudya mawonekedwe osalala, "osungunuka mkamwa" omwe ogula amagwiritsa ntchito ndi ma gummies apamwamba, marshmallows, ndi panna cotta. Nthawi zambiri zimakhala ndi kuchuluka kwa 2–10% kutengera mphamvu ya maluwa.(KULA, nd).
Gelatin imapezeka m'mitundu iwiri ikuluikulu:Mtundu A(yokonzedwa ndi asidi) yokhala ndi mfundo yayikulu ya isoelectric (~7–9), ndiMtundu B(yokonzedwa ndi alkali) yokhala ndi mfundo yotsika ya isoelectric (~4.7–5.4). Kusiyana kumeneku kumakhudza momwe gelatin imagwirira ntchito ndi pH ya kapangidwe kanu - kofunikira mukayiphatikiza ndi machitidwe a zipatso za acidic kapena mkaka. Mphamvu ya gel (80–320) ndiye imayang'anira kulimba kwa gel. Kuti mudziwe zambiri, onani buku lathu lotsogolera pakumvetsetsajelimphamvu.
