Ntxiv nrog rau qhov saj, qhov xav tau ntawm cov npias zoo yog qhov tseeb ntawm npias. Clarity xav kom cov cawv yuav pob tshab thiab ci, tsis muaj cov khoom me me thiab cov teeb meem raug tshem tawm, thiab npias ntawm qhov zoo tsis tuaj yeem ua tiav cov txiaj ntsig pob tshab.
Ua rau huab npias
Npias yog cov dej cawv uas ua los ntawm barley ua cov khoom xyaw tseem ceeb, nrog cov khoom siv hmoov txhuv nplej siab xws li mov ua cov khoom siv, thiab cov khoom siv malt thiab cov khoom siv pabcuam yog saccharified thiab fermented. Nws yog cov tshuaj colloidal nrog tsis muaj zog stability, nyob rau hauv uas cov proteins, aldoses, polyphenols thiab colloids nyob rau hauv hops yuav tsim flocs thaum lub sij hawm brewing txheej txheem, cuam tshuam rau stability thiab transparency ntawm npias.
Thaum lub sijhawm khaws cia, vim muaj kev cuam tshuam ntawm ib puag ncig, xws li lub teeb, oxygen, kev co, thiab lwm yam, lub npias kuj yuav turbid thiab precipitated. Txhawm rau tshem tawm qhov tshwm sim no thiab tau txais cov npias zoo nrog cov ntsiab lus siab, ua npuas ncauj, nplua nuj khoom noj khoom haus thiab saj zoo, ib yam yog qhov tseem ceeb.
Cov nyhuv ntawm bromelain rau kev txhim kho npias zoo
Bromelain yog ib tug ntshiab natural cog protease muab rho tawm los ntawm pineapple txiv hmab txiv ntoo stems, nplooj thiab tawv nqaij, purified, purified, concentrated, enzyme immobilized thiab khov-dried. Nws tuaj yeem hydrolyze ntau yam proteins hauv npias.
Nws muaj peev xwm hydrolyze macromolecular proteins nyob rau hauv npias thiab ib nrab hydrolyze ib co tsim complexes, zoo tshem tawm sediment nyob rau hauv npias, tsim ntau polypeptides los yog amino acids, thiab xyuas kom meej siab clarity ntawm npias thaum khov cia.
Nws tuaj yeem txhim kho saj ntawm npias, kho qhov sib xyaw thiab qhov sib piv ntawm thawj polypeptides thiab amino acids, thiab txhim kho kev pab cuam ntawm npias npuas. Cov ntsiab lus amino acid tau nce mus rau qhov sib txawv, tab sis kuj txhim kho cov khoom noj muaj txiaj ntsig ntawm npias.
Tsis tas li ntawd, cov ntsiab lus ntawm cov protein nyob rau hauv wort tuaj yeem hydrolyzed los ntawm cov protein kom muab cov nitrogen qhov xav tau hauv cov txheej txheem fermentation ntawm brewer cov poov xab.
Cov nyhuv ntawm bromelain hauv npias tsim
1. Txhim kho qhov zoo ntawm npias. Tam sim no, ntau yam ntawm npias yog dazzling, thiab cov neeg siv khoom muaj kev xav tau ntau dua thiab siab dua rau cov npias zoo. Ntxiv bromelain hauv cov txheej txheem tsim npias tuaj yeem daws qhov turbidity ntawm npias, txhim kho saj ntawm npias, ua kom cov npias npias, thiab txhim kho cov khoom noj muaj txiaj ntsig ntawm npias.
2. Txo cov nqi tsim khoom. Nrog rau kev sib tw ua lag luam muaj zog, ua kom luv luv lub voj voog ntau lawm thiab txo cov nqi tsim khoom los ntawm kev siv tshuab thev naus laus zis yog qhov tseem ceeb tshwj xeeb rau kev tsim npias. Kev sib xyaw ua ke ntawm cov cuab yeej siv niaj hnub enzyme thiab cov cuab yeej siv tshuab ua npias tuaj yeem tsis tsuas yog txhim kho npias zoo, tab sis kuj txo cov nqi tsim khoom, ua rau cov khoom siv raw khoom tsis zoo, txo kev cia siab ntawm malt zoo thiab hop zoo, thiab pab txhim kho kev tsim khoom.
