Stevioside yog muab rho tawm los ntawm nplooj ntawm Stevia rebaudiana, cov nroj tsuag sib xyaw.Stevia rebaudiana muaj cov yam ntxwv ntawm kev qab zib thiab tsis tshua muaj zog kub.Nws qab zib yog 200-300 npaug ntawm sucrose, thiab nws cov nqi calorific tsuas yog 1/300 ntawm sucrose. Raws li cov khoom qab zib uas nquag siv, steviosides tuaj yeem siv dav hauv ntau yam khoom noj, dej haus, tshuaj, thiab kev lag luam tshuaj txhua hnub. . Cia peb saib cov yam ntxwv ntawm stevioside hauv cov ntawv hauv qab no.
Yam ntxwv ntawmStevioside
1. Hygroscopicity
Stevioside nrog purity ntau tshaj 80% yog dawb crystals los yog hmoov nrog me ntsis hygroscopicity.
2. Solubility
Yooj yim soluble hauv dej thiab ethanol, thaum tov nrog sucrose, fructose, qabzib, Maltose, thiab lwm yam, tsis tsuas yog steviol glycoside saj yog ntau ntshiab, tab sis kuj cov qab zib yuav multiplied.Cov qab zib no tsis muaj cua sov tsis kam thiab tsis yooj yim raug. rau lub teeb.Nws yog qhov ruaj khov heev hauv pH ntau ntawm 3-10 thiab yooj yim khaws cia.
3. Kev ruaj ntseg
Cov tshuaj muaj kev ruaj ntseg zoo, thiab tseem ruaj khov heev tom qab kev kho cua sov nyob rau hauv lub pH ntau yam ntawm cov dej haus thiab cov khoom noj.Stevioside qhia me ntsis kev hloov tom qab muab cia rau hauv cov organic acid tov uas muaj sucrose rau rau lub hlis; Nws tsis decompose nyob rau hauv acidic thiab alkaline. media, uas tuaj yeem tiv thaiv fermentation, discoloration, thiab sedimentation; Nws tuaj yeem txo cov viscosity, txwv tsis pub cov kab mob loj hlob, thiab txuas ntxiv cov khoom txee lub neej.
4. Qab zib saj
Steviosidemuaj ib tug ntshiab thiab refreshing qab zib, nrog ib tug saj zoo li cov qab zib dawb, tab sis lawv qab zib yog 150-300 npaug ntawm sucrose.Lub extracted ntshiab Leibaodi A qab zib muaj ib tug qab zib 450 npaug ntawm sucrose, ua rau ib tug zoo saj. Lub dissolution kub ntawm stevia qab zib yog ze ze rau nws qab zib thiab saj. Feem ntau, tsis tshua muaj kub dissolution muaj ib tug siab qab zib, thaum kub dissolution muaj ib tug zoo saj tab sis tsis muaj qab zib.Thaum nws yog tov nrog citric acid, Malic acid, Tartaric acid. , lactic acid, amino acid, thiab lwm yam., nws muaj cov tshuaj tua kab mob thiab ua kom tsis muaj menyuam nyob rau tom qab saj ntawm stevioside.Yog li ntawd, thaum nws tov nrog cov khoom saum toj no, nws tuaj yeem ua lub luag haujlwm kho thiab txhim kho cov qab zib zoo ntawm stevioside.
Kev piav qhia: Lub peev xwm ua tau zoo thiab cov ntawv thov tau hais hauv kab lus no yog tag nrho los ntawm cov ntaub ntawv muaj nyob rau pej xeem.
