Kaofela ka Matla a Diastatic

Haeba u bala ka lijo-thollo tse malted , mohlomong u ntse u tla hohle ho feta lentsoe "diastatic." Matla a tšabehang le mohloli oa oona, li-enzyme tse tšoaetsanoang, li phetha karolo ea bohlokoa ho fetoleng ha starch ea lijo-thollo maling.

Bohle ba harese bo qala ka bongata ba lik'hemik'hale tse tšosang. Tsena ke peo, ka morao tsohle, 'me starch ka hare ho peo e reretsoe ho fetoloa ke li-enzyme tse senyang ka hare ho tsoekere ho fepa semela ha e ntse e hōla.

Ho feta moo, sepheo sa rona se tšoana le semela sa harese.

Ho fapana le harese, leha ho le joalo, re boetse re thahasella mmala le tatso. Mokhoa oa ho hlatsoa le ho chesa lijo tse nang le malate o hlahisa mefuta e mengata ea mefuta e fapa-fapaneng ea malt e ntan'o lebisa phapang ea biri ho tloha palest lager ho ea ho maqhubu a mabeli.

Thekiso ea boholo ba litlolo le mebala ke ho lahleheloa ke matla a marang-rang. E le molao oa motheo oa lesela, leseli le nang le malt ke, nako e telele le e chesang e chesitsoe, 'me ho feta moo, li-enzyme tsa eona tse senyang li senyehile.

Ke kahoo re sebelisang malts a motheo . Li-malts tsa motheo li koahetsoe habobebe, li boloka boholo ba li-enzyme tsa bona tse hlahisang likokoana-hloko. Ho kenyeletsa malts a mangata a mangata ka lijo tsa lijo-thollo tsa hau ho bolela hore lijo tse ling tsa hao tse ngata, joaloka li-malts tse hlakiloeng le tse halikiloeng , li tla fetoloa ho tsoekere e tsoekere nakong ea sesepa.

Ena ke e 'ngoe ea phapang e khōlō pakeng tsa mela e' meli le harese ea mola o tšeletseng .

Le ha bobeli bo sebelisoa hangata Amerika Leboea e le malts a motheo, mola o tšeletseng o atisa ho ba le matla a maholo ho feta mela e 'meli. Ke ka lebaka leo joala bo boima bo tloaelehileng bo atisang ho fetelloa ka mefuta e tšeletseng ea litebelisoa tsa methapo.

Empa li-enzyme tsa diastatic li etsa'ng, hantle?

Ha re bua ka "li-enzyme tse kotsi," re hlile re bua ka li-enzyme tse tharo tse sa tšoaneng: alpha-amylase, beta-amylase, le limote dextrinase.

E mong le e mong o na le mosebetsi oa hae, o fetola mofuta o mong oa starch ho mefuta e fapaneng ea tsoekere. (Ho na le bone, alpha-glucosidase, empa ha e hlile e thusa ka mokhoa oa ho noa).

Li-enzyme tsena li hloka mongobo le mocheso o khethehileng e le hore li etse mosebetsi oa tsona, ke ka lebaka leo sethala se lokelang ho tšoaroa ka mocheso o tsitsitseng ka nako ea ts'ebetso - e pholile haholo 'me li-enzyme li ke ke tsa kenngoa ka lijaneng, hape chesa 'me ba tla chesa. Ha e le hantle, enzyme e 'ngoe le e' ngoe e na le mocheso o fapaneng haholo moo o sebetsang ka ho fetisisa, empa kae kapa kae pakeng tsa 150 F le 155 F ke ho sekisetsa ho sebelisoang hangata.

Ha u ntse u lokisetsa chelete ea lijo-thollo tsa hau, ke habohlokoa ho etsa bonnete ba hore u na le matla a lekaneng a diastatic ho fetola sethala kaofela. Haeba u sa etse joalo, biri ea hau e tla ba e monate haholo ebile e fokola.

Hangata matla a diastatic a malt hangata a lekanyetsoa ho sebelisoa boitsebiso bo bitsoang "degrees Lintner." Nomoro ena e ka arola kae kapa kae ho tloha ho 0, linthong tse kang li-malts tse ntšo le li-adjunct tse sa hlakang, ho tse ling tse 180 maltsaneng a mang. Ha e le hantle, malt o hloka bonyane li-degrees tse 30 Lintner ho khona ho fetola tsoekere eohle ea eona.

Ka pontšo e tšoanang, litekanyetso tsohle tsa lijo-thollo li lokela ho ba le likhato tse 30 tsa Lintner ho netefatsa hore sethala se tla fella ka ho sokoloha ka katleho.

Ho bonolo haholo ho tseba sena. Fokotsa matla a diastatic e 'ngoe le e' ngoe ea malt (degrees Lintner) ka boima ba eona ka litekete tsa lijo-thollo. Eketsa lenane le leng le le leng la malt, ebe o arola nomoro eo ka boima ba litekanyetso tsa chelete ea lichelete ka lik'hilograma. Haeba palo ena e feta 30, o lokela ho ba hantle.

Ka mohlala, a re hlahlobeng recipe:

7 lbs. malt a lebala, likhato tse 160 L

1 lb. malt a Munich, likhato tse 25 L

0.5 lb. malt amber, likhato tse 0 L

Ea pele, re atisa boima ba malt ka 'ngoe ka matla a eona a diastatic.

Pale = 7 x 160 = 1120

Munich = 1 x 25 = 25

Amber = 0.5 x 0 = 0

Hona joale re eketsa lipalo tseo tse tharo hammoho.

1120 + 25 + 0 = 1145

'Me re arola seo ka palo ea lik'hilograma tse etsang chelete ea lijo-thollo

1145/8 = 143.125

Ho joalo ka ho feta 30, kahoo re hantle! Ha e le hantle ha u ntse u noa sesebelisoa sa lijo-thollo 'me u kenyelletsa malt ea motheo, u tla hlaka.

Leka ho noa ka ntle ho malt, leha ho le joalo, 'me u tla ba mathateng. Sheba litefello tsa lijo-thollo tse kang ena:

5 lbs. Ma malt a Munich, likhato tse 25 L

2 lbs. amber malt, 0 likhato L

1 lb. malt a kristale, 0 likhato L

1 lb. malt a tsokolate, 0 likhato L

0.5 lb. malt a matšo, 0 likhato L

Etsa lipalo, 'me o tla tsoa ho likhato tse 13 tsa L bakeng sa chelete eohle ea lijo-thollo. Setoto sena se ke ke sa fetoha hantle, 'me u tla tsoha ka biri e sa tloaelehang, e monate e tlaase haholo joala.

Hona ke bothata ba batlōli ba bangata ba kenang ha ba ntse ba noa molato. E le ho qhaqha mofuthu, o qala ho noa joalokaha o ne o tla etsa ka bongata ba lijo-thollo, empa u eketsa lisebelisoa tse ling tsa malt pele ho pheha. Sena se u fa matla a mangata a ho laola holim'a mefuta e mengata ea litlolo le mebala ho feta ho noa, ntle le tšenyo le lisebelisoa tse eketsehileng tsa ho noa lijo-thollo.

Bothata ba ho phalla ka mofuthu, leha ho le joalo, ke matla a diastatic. U ke ke ua eketsa lijo-thollo leha e le life feela, kapa ua beha kotsi ea hore li se ke tsa nona. Ho phahamisa lik'hilograma tse peli tsa lijo-thollo tse malted ka biri ea hau ho ka e fa mmala o motle, empa ka matla a tšabehang a digrama tse 0 L, e tla fana ka tatso ea hao e monate o monate oo u sa kang ua o rera.

Esita le ha u se u le mothating, kenyelletsa malt ea motheo ho etsa bonnete ba hore biri ea hau e na le matla a lekaneng a ho fetola likhahla tsa eona tse tsoekere.
