Mtundu wa Mbatata Wofiirira (Ufa wa Anthocyanin)
Chiyambi
Mtundu wa Purple Sweet Potato umapezeka pochotsa muzu wa mbatata, mbatata zofiirira zimakhala ndi mnofu wofiirira komanso khungu lofiirira kapena lofiirira. Mtundu wofiirira ndi wachilengedwe ndipo umabwera chifukwa cha antioxidant yotchedwa anthocyanin, yomwe imapangitsanso mtundu wa kabichi wofiira, vinyo wofiira, ndi kolifulawa wofiirira. Anthocyanins ndi utoto wa flavonoid womwe umapangitsa kuti zipatso ndi ndiwo zamasamba zikhale zofiirira, zabuluu ndi/kapena zofiira.
Chomaliza ndi madzi ofiira ofiirira kapena ufa, womwe umasungunuka mosavuta m'madzi ndi ethyl alcohol.
Kuzindikira kwa pH: Monga ma anthocyanins ena, mtundu umasintha ndi pH:
Asidi (pH Wofiira kwambiri-wofiirira
Chosalowerera (pH≈7): Wofiirira wachifumu
Alkaline (pH >7): Buluu-wobiriwira (wosowa kwambiri pakugwiritsa ntchito pophikira)
Asidi (pH Wofiira kwambiri-wofiirira
Chosalowerera (pH≈7): Wofiirira wachifumu
Alkaline (pH >7): Buluu-wobiriwira (wosowa kwambiri pakugwiritsa ntchito pophikira)
Zinthu Zokhazikika
Kukana Kutentha: Anthocyanins yokhala ndi acylated imasunga utoto bwino ikaphika (monga kuphika, kuwira) kuposa mitundu yopanda acylated. Komabe, kutentha kwambiri kwa nthawi yayitali (>100°C) kungayambitse bulauni chifukwa cha caramelization.
paKuwala ndi Mpweya: Kuwonongeka kwa nthaka kumawonjezeka kwambiri chifukwa cha kuwala kwa UV ndi mpweya. Kusunga m'zidebe zamdima komanso zosalowa mpweya n'kofunika kwambiri.

Ntchito Zamakampani Ndi Zamalonda
paKupaka utoto kwa chakudya chachilengedwe:Amachotsedwa ngati ufa kapena madzi ochulukirapo (monga "Purple Sweet Potato Color" kapena PSC) wa ayisikilimu, zakumwa, ndi zinthu zophikidwa. Amalowa m'malo mwa utoto wopangidwa (monga Red 40) mu zinthu "zoyera".
paKukhazikika Kwambiri: Imakana kutha kwa zakudya za pH zosalowerera (monga mkaka) kuposa utoto wochokera ku beetroot
paMankhwala ndi Zodzoladzola:Zophimba Mapiritsi: Zimalowa m'malo mwa utoto wopangidwa mu mavitamini ndi zowonjezera
Ma formula Osamalira Khungu: Ma Anthocyanins omwe ali mu mafuta amalimbana ndi kupsinjika kwa okosijeni komwe kumachitika chifukwa cha UV

Mbali
Ndi mphamvu zachilengedwe zoletsa ukalamba, mtundu wowala, mphamvu yopaka utoto wamphamvu, kukana kuwala ndi kutentha. Mu madzi okhala ndi asidi, imakhala yofiirira ndipo mtundu wake umakhala wokhazikika.
Kugwiritsa ntchito
Amagwiritsidwa ntchito popanga vinyo, madzi a zipatso, zinthu zophikidwa mu uvuni, maswiti, jelly, zipatso, mankhwala ndi zina.
