APPLICATION CHARACTERISTICS NTAWM GELATIN SOFT CANDY
Gelatin yog thawj gel siv los ua cov khoom qab zib elastic gummy vim tias nws muab cov khoom qab zib muag muag muaj zog elastic zoo nkauj.Nyob rau hauv cov txheej txheem ntawm cov khoom qab zib muag muag, thaum cov gelatin tov yog txias rau 22-25 ℃, gelatin ua ib qho khoom.Raws li nws cov yam ntxwv, gelatin tov yog tov nyob rau hauv lub syrup thiab ncuav rau hauv pwm thaum nws yog kub.Tom qab txias, ib qho duab ntawm gelatin jelly tuaj yeem tsim.
Qhov tshwj xeeb daim ntawv thov tus yam ntxwv ntawm gelatin yog kub reversibility.Cov khoom uas muaj gelatin yog nyob rau hauv ib tug tov lub xeev thaum rhuab, thiab hloov mus rau hauv ib tug khov lub xeev tom qab txias.Vim tias qhov kev hloov pauv sai sai no tuaj yeem rov ua dua ntau zaus, cov yam ntxwv tseem ceeb ntawm cov khoom tsis hloov hlo li.Yog li ntawd, qhov zoo ntawm gelatine siv rau cov khoom qab zib jelly yog tias cov tshuaj kho tau yooj yim heev.Txhua yam khoom gelled los ntawm cov hmoov pwm uas muaj qhov tsis xws luag tuaj yeem ua kom sov thiab rov ua dua rau 60 ℃ - 80 ℃ ua ntej yuav rov ua dua yam tsis muaj kev cuam tshuam rau nws qhov zoo.
Khoom noj khoom haus qib gelatin isa natural protein nrog dissociable carboxyl thiab amino pawg ntawm cov saw molecular.Yog li, yog tias txoj kev kho mob txawv, tus naj npawb ntawm carboxyl thiab amino pawg ntawm cov saw molecular yuav hloov, uas txiav txim siab theem ntawm isoelectric point ntawm gelatin.Thaum tus nqi pH ntawm cov khoom qab zib jelly yog nyob ze ntawm isoelectric point ntawm gelatin, qhov zoo thiab tsis zoo nqi dissociated los ntawm gelatin molecular saw yog sib npaug, thiab cov protein yuav tsis ruaj khov thiab gelatinous.Yog li, nws raug pom zoo kom xaiv qhov isoelectric point ntawm gelatin kom deb ntawm pH tus nqi ntawm cov khoom, vim hais tias pH tus nqi ntawm fruity gelatin jelly khoom qab zib yog feem ntau ntawm 3.0-3.6, thaum lub isoelectric point ntawm acid kua nplaum feem ntau siab dua, ntawm 7.0-9.5, yog li kua qaub kua nplaum yog qhov haum tshaj plaws.
Tam sim no, Gelken muab khoom noj gelatin uas tsim nyog rau kev tsim cov khoom qab zib muag.Lub zog jelly yog 180-250 tawg.Qhov siab dua lub zog jelly, qhov zoo dua qhov hardness thiab elasticity ntawm cov khoom muab.Viscosity yog xaiv ntawm 1.8-4.0Mpa.s raws li lub zog jelly.
