Daim ntawv thov ntawm Molecular Distilled Monoglycerides hauv Ice Cream

Abstract:Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob ntawm kev lag luam, kev lag luam khoom noj khoom haus tau tsim sai heev. Kev ua lag luam muaj kev xav tau ntau dua thiab siab dua rau qhov zoo ntawm cov ice cream. Yuav ua li cas los txhim kho qhov zoo thiab saj ntawm ice cream ntawm tus nqi qis yog ib qho kev txhawj xeeb tseem ceeb ntawm cov ice cream manufacturers.Monoglycerides muaj kev cuam tshuam loj heev rau qhov zoo ntawm ice cream. Molecularly distilled monoglyceride tau dhau los ua cov khoom xyaw tseem ceeb hauv cov khoom xyaw ice cream. Daim ntawv no qhia txog daim ntawv thov ntawm molecularly distilled monoglyceride hauv cov dej khov kom meej, txhawm rau muab kev siv rau kev tsim cov ice cream.

Monoglyceride yog cov khoom noj muaj txiaj ntsig zoo emulsifier thiab surfactant, uas tuaj yeem ua lub luag haujlwm ntawm emulsification, foaming, dispersing thiab defoaming, thiab tiv thaiv cov hmoov txhuv nplej siab. Nws yog dav siv nyob rau hauv ntau yam zaub mov teb thiab yog cov feem ntau siv emulsifier nyob rau hauv cov zaub mov. . Tebchaws Europe thiab Tebchaws Meskas tau siv lawv rau kev lag luam zaub mov hauv xyoo 1930s. Hauv xyoo 1960, cov tshuab molecular distillation pib siv rau kev sib cais thiab kev huv ntawm monoglycerides. Nyob rau xyoo 1980, Guangzhou Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Lub Teeb (tus thawj coj ntawm Meizhan Group Additives Company) tau ua tus thawj coj hauv kev tshawb nrhiav cov txheej txheem molecular distillation ntawm monoglycerides. Nyob rau xyoo 1990, kev tsim khoom lag luam tau pom zoo, thiab cov khoom tsim tawm txhua xyoo tau mus txog ntau txhiab tons.

1. Cov nyhuv ntawm monoglycerides rau qhov zoo ntawm ice cream

CovmonoglyceridesHloov ib feem ntawm cov protein complex tau adsorbed rau ntawm qhov chaw ntawm cov rog globules, uas muaj kev cuam tshuam loj rau cov dej khov zoo. Hauv cov txheej txheem tsim khoom, kev cuam tshuam ntawm monoglyceride feem ntau yog tshwm sim hauv cov ntsiab lus hauv qab no: kev txhim kho cov dispersibility ntawm cov roj hauv qhov sib tov, ua rau cov roj me me zoo thiab sib npaug sib npaug, thiab txhim kho kev ruaj ntseg ntawm emulsion; txhawb kev sib cuam tshuam ntawm cov rog thiab cov protein, ua rau Emulsion destabilization lossis demulsification pab tswj cov agglomeration thiab cohesion ntawm cov rog; tswj kev tsim cov dej khov ntxhib, muab cov dej khov ua kom zoo thiab ua kom zoo; txhim kho stability thiab zoo tuav; tiv thaiv ice cream los ntawm kev khaws cia Thaum lub sij hawm tus txheej txheem, nws shrinks thiab deforms los txhim kho lub qhov ncauj melting.

2. Lub luag haujlwm ntawm monoglycerides hauv kev sib xyaw thiab homogenization

Nyob rau hauv cov khoom xyaw ntawm ice cream, yog tias tag nrho cov rog los ntawm mis nyuj rog, tsis tas yuav ntxiv ib qho emulsifier kom stabilize lub emulsion. Qhov no yog vim hais tias cov rog nyob rau hauv cov khoom noj siv mis nws tus kheej muaj nyob rau hauv ib daim ntawv emulsified, thiab saum npoo ntawm cov roj yog them los ntawm casein. Nws tuaj yeem ua tau zoo dispersed nyob rau hauv aqueous tov los tsim emulsion. Yog tias lwm cov roj uas tsis yog mis nyuj ntxiv rau cov khoom xyaw, ib feem ntawm cov monoglyceride yuav tsum tau ntxiv kom ruaj khov cov rog kom tsim tau ib homogeneous emulsion los tiv thaiv cov khoom stratification los ntawm kev cuam tshuam cov haujlwm tom ntej.

Thaum lub sij hawm homogenization txheej txheem, ntau yam lipoproteins yog tsim los ntawm monoglycerides, rog thiab proteins, uas stabilize lub tiv thaiv zaj duab xis ntawm rog thiab muaj tej yam kev ua hauj lwm nyob rau hauv ice cream mix..

2.1. Lub luag haujlwm ntawm monoglycerides hauv kev laus

Thaum lub sij hawm kev laus, cov ntaub ntawv ntawm cov dej khov tau hloov pauv ntau lub cev thiab tshuaj lom neeg, feem ntau suav nrog cov dej ntawm cov kua mis protein, ua kom tiav cov dej stabilizers, crystallization ntawm cov kua roj thiab tshuaj xyuas cov protein. Ntawm cov kev hloov pauv ntawm lub cev thiab tshuaj lom neeg, kev cuam tshuam ntawm monoglyceride yog qhov loj heev uas muaj cov lipids ua kua los tiv thaiv crystallization thiab protein desorption..

2.1.1. TNws cov nyhuv ntawm monoglycerides ntawm cov kua roj crystallization

Thaum lub sij hawm laus, cov rog tiv thaiv los ntawm crystallizing vim qhov kub thiab txias. Thaum lub sij hawm crystallization, cov rog ntawm qhov sib txawv melting kub sib cais nyob rau hauv cov dej khov sib tov, thiab qhov siab dua melting point triglyceride crystallizes ua ntej, thiab yog taw qhia rau saum npoo ntawm cov roj globules los ua cov muaju. Lub luag hauj lwm ntawm lub nucleus ua rau cov roj tsawg-melting anti-crystallizing kua ntau dua los yog tsawg nyob rau hauv cov tub ntxhais raws li cov muaj pes tsawg leeg ntawm cov rog, yog li cov rog-anti-particles muaj ib tug tej yam plasticity, thiab cov khoom yog raug rau cov neeg kho tshuab muaj zog. kev txiav txim thaum lub caij khov. , Cov khoom siv lead ua yuav raug khawb, thiab cov kua roj qhwv hauv nws yuav raug nyem tawm. Cov kua roj extruded tuaj yeem tsim cov txheej txheem tiv thaiv rau saum npoo ntawm cov npuas huab cua uas tau nplawm hauv, uas yuav pab txhim kho qhov nthuav dav, thiab kev sib cuam tshuam ntawm cov kua roj, ua ke nrog cov protein, cov roj tawg tau txuas nrog rau daim ntawv. cov pob txha ntawm cov ice cream, yog li cov crystallization ntawm cov kua roj thaum lub sij hawm kev laus muaj ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm cov ice cream.

Lub crystallization ntawm cov kua roj yog feem ntau cuam tshuam los ntawm hom rog, thaum monoglycan tuaj yeem cuam tshuam rau cov rog crystallization.

2.1.2. Cov nyhuv ntawm monoglycerides ntawm cov protein desorption

Casein thiab whey protein yog adsorbed nyob rau saum npoo ntawm cov roj globules kom stabilize cov rog globules, tab sis nyob rau hauv cov txheej txheem ntawm cov ice cream, yog hais tias cov mis nyuj protein ntau stably adsorbed nyob rau saum npoo ntawm cov roj globules, nws yuav tsis conducive mus rau lub ice cream. overflow thiab agglomeration ntawm cov rog, yog li cuam tshuam rau lub cev pob txha ntawm cov ice cream. Yog li ntawd, qhov tsim nyog desorption ntawm cov protein nyob rau hauv cov txheej txheem kev laus ntawm cov khoom siv khov nab kuab yuav pab txhim kho cov dej khov zoo, thiab ntxiv ntawm monoglyceride yuav txhawb kev desorption ntawm cov protein. Nws muaj zog dua li cov protein. Thaum muaj kev sib cuam tshuam, monoglyceride muaj txiaj ntsig zoo dua rau cov lipids, yog li monoglycerides tuaj yeem txhawb kev desorption ntawm cov protein, kom lipids tuaj yeem tawm ntawm daim nyias nyias.

2.2. Lub luag haujlwm ntawm ib qho sweetener hauv khov

Tom qab kev laus, cov khoom siv khov nab kuab pib khov. Thaum lub sijhawm txheej txheem no, viscosity ntawm cov khoom siv khov nab kuab nce, thiab ib feem ntawm cov dej hloov mus rau hauv cov dej khov nab kuab. Nyob rau tib lub sijhawm, huab cua maj mam sib xyaw ua kom cov ice cream nthuav dav. Hauv cov txheej txheem no, cov rog globule tuaj yeem ua kom tsis muaj zog. , los txhawb lub extrusion ntawm kua roj thaum lub sij hawm whipping txheej txheem. Nyob rau tib lub sijhawm, txij li cov kev hloov pauv ntawm cov khoom siv hauv cov txheej txheem no yog raws li cov txheej txheem kev laus, cov nyhuv ntawm monoglycerides hauv cov txheej txheem no tuaj yeem cuam tshuam ncaj qha los ntawm qhov zoo ntawm cov khoom qab zib kawg. tawm los.

Los ntawm kev soj ntsuam saum toj no, nws tuaj yeem pom tias monoglyceride muaj qhov cuam tshuam tseem ceeb ntawm cov khoom qab zib zoo, tab sis qhov sib ntxiv tsis yog qhov zoo dua. Nws yog ntseeg hais tias yog hais tias monoglyceride ntau dhau lawm, cov casein yuav desorbed kiag li thaum lub sij hawm kev laus. Cov roj cov ntsiab lus tseem ceeb heev, yog li cov roj tawg tawg thaum lub sijhawm khov tsis tuaj yeem tsim cov pob txha zoo vim tsis muaj kua roj. Nyob rau tib lub sijhawm, cov cua npuas nplawm vim qhov tsis muaj kev tiv thaiv ntawm cov kua roj yuav ua rau qhov nthuav dav txo qis thiab saj yuav greasy. Hauv cov txheej txheem tsim khoom tiag tiag, nws yog ib qho tsim nyog los tswj tus nqi ntawm ib qho khoom qab zib, thiab cov nyhuv ntawm ntau yam emulsifiers zoo dua. Nws yuav siv ntau qhov kev ntsuam xyuas kom tau txais cov dej khov zoo dua.
