Txheej txheem cej luam ntawmKua txiv hmab txiv ntoo
Malt syrup yog ib yam khoom qab zib ua los ntawm cov hmoov txhuv nplej siab los ntawm cov khoom siv raw xws li pob kws hmoov txhuv nplej siab los ntawm kev ua kua, saccharification, filtration, thiab concentration, nrog maltose ua nws cov khoom tseem ceeb. Raws li cov ntsiab lus maltose, nws tuaj yeem muab faib ua M40, M50, M70, thiab crystalline maltose. Nws qhov qab zib yog li 30% -40% ntawm sucrose, thiab nws muaj cov dej solubility zoo heev, lipophilicity, acid thiab kub tsis kam, ua rau nws siv dav hauv kev tsim khoom qab zib, ncuav mog qab zib, khoom qab zib khov, thiab tshuaj.
Cov Txheej Txheem Tsim Khoom ntawmKua txiv hmab txiv ntoo
Kev tsim khoom lag luam niaj hnub no feem ntau yog siv covtxoj kev ua kom puv enzyme, uas muaj cov xwm txheej tsis tshua muaj zog, muaj kev tshwj xeeb siab, thiab yooj yim siv tshuab thiab kev lag luam piv rau cov tshuaj malt extract saccharification ib txwm muaj. Lub enzyme tseem ceeb hauv cov txheej txheem yogβ-amylase, uas hydrolyzes α-1,4 glycosidic bonds los ntawm cov kawg uas tsis txo qis ntawm cov hmoov txhuv nplej siab los tsim maltose tab sis tsis tuaj yeem hydrolyze α-1,6 glycosidic bonds.
Kev tsim cov kua txiv malt feem ntau yog tsom mus rau:
- Siab-kua txiv qaubnrog cov ntsiab lus khov kho ≥80%, uas tseem ruaj khov yam tsis muaj crystallization nyob rau hauv cov xwm txheej cia khoom ib txwm muaj.
- Kev tsim cov maltose ntshiab.
Hauv kev tsim cov kua txiv hmab txiv ntoo siab, qhov degree ntawm liquefaction yuav tsum tau tswj kom zoo, nrog rauDE (Dextrose Equivalent) tus nqi tsis pub tshaj 10Txawm li cas los xij, tus nqi DE qis dua tuaj yeem ua rau muaj viscosity ntau ntxiv thaum lub sijhawm saccharification, txo qis enzymatic efficiency, thiab cuam tshuam tsis zoo rau qhov zoo ntawm cov khoom kawg.
Cov Kev Cov nyom thiab Kev Txhim Kho ntawm High-Concentration Starch Milk Hydrolysis
Lub hydrolysis ntawm starch rau qab zib muaj ob theem:liquefaction thiab saccharificationCov txheej txheem ib txwm siv25% -35% mis hmoov txhuv nplej siab, xav tau dej ntau. Vim tias tsuas yog ib feem me me ntawm cov dej no xwb uas xav tau rau cov tshuaj enzymatic, feem ntau ntawm nws yuav tsum tau evaporated tom qab saccharification, ua rau muaj kev nce ntxivkev siv hluav taws xob thiab cov nqi tsim khoomTsis tas li ntawd xwb, qee cov txheej txheem fermentation xav taucov kua qab zib uas muaj ntau tshaj 40% concentration, tsim kom muaj kev xav tau cov khoom khov kho ntau dua hauv cov kua dej saccharified.
Ua rau kom nce ntxivcov hmoov txhuv nplej siab concentrationyog ib txoj hauv kev zoo los txo cov nqi evaporation. Txawm li cas los xij, cov txheej txheem muaj zog ntau ua rau muaj kev nce ntxivviscosity, tsis tiav substrate hydrolysis, thiab txo qis enzymatic efficiency. Hauv kev tsim khoom lag luam, kom tau txaiskua txiv qaubnrog ≥90% maltose cov ntsiab lus, qhov concentration ntawm cov hmoov txhuv nplej siab feem ntau yog tswj hwm ntawm10% -20%, tsis pub tshaj25%Kev tshawb fawb yav tom ntej yuav tsum tsom mus rau kev ua kom zoo dua ntawm enzymatic hydrolysis nyob rau hauv cov xwm txheej siab-substrate concentration kom txhim kho kev tsim khoom thiab kev lag luam zoo.
