Nekuvandudzwa kwezvekurarama kwevanhu, zvinodiwa nevatengi zvekudya hazvingogumira kune hunhu hunokosha, asi ruvara, runyararo, kuravira, kutsva, etc.

Emulsifiers, sekudya kwekudya kwekunyepedzera, kutamba basa rakakosha muindasitiri yechikafu. Ngatitorei kutarisa muchina wekuita kwechiitiko che emlsifiers!

Emulsion

Mhedzisiro yakajairika muchikafu ine mvura kana mhinduro yemvura, yakanyorwa pamwe chete seiyo hydrophilic chikamu; Chimwe chikamu chimwe chikamu cheshanduko chinokasira nemvura, chinozivikanwawo sechiyero chesimba. Zvishandiso zviviri zvisina kujairika, zvakadai semvura nemafuta, zvinogona kuumba marudzi maviri emamita kana akasanganiswa, mvura yemvura mumafuta (o / w) uye mvura mumafuta (w / o) emultions.

Mumvura muhari yemafuta, mafuta anoparadzirwa semadonhwe emvura mumvura, nemafuta madonhwe seanopararira chikamu nemvura seyekuparadzanisa svikiro. Semuenzaniso, mukaka wemombe ndeye o / w elsion; Mumvura mumamambo emafuta, zvinopesana ndezvechokwadi. Mvura yakapararira semakonzo madonhwe mumafuta, nemvura sokuparadzira chikamu nemafuta seyekuparadzanisa svikiro. Semuenzaniso, butter rekunyepedzera rudzi rwe w / o emulsion.

Maitiro ekuita kwechiito emulsifiers

Chikafu chechipungu, chinozivikanwawo serivicant, zvinhu izvo zvinoshandura zvinwiwa zvine mutsindo zvakadzikira zvikamu (emulsions). Kana uwedzere kudya, ivo vanogona kuderedza zvakanyanya kusawirirana pakati pemvura uye nemvura, vachibvumira mafuta asina kuchena (hydrophobic zvinhu) uye mvura (hydrophilic zvinhu) kuti vagadzire emultions seyakawedzerwa chikafu.

Kune rimwe ruoko, emulsifiers inoumba iyo yakaonda molecular layer payakaomeswa anodzvinyirira nzvimbo nzvimbo, kuderedza iyo yemahara simba reiyo yese system uye kuumba mitsva mitsva. EMLSIFIER mamorekuru ane hydrophilic uye oleophilic mapoka emapoka, ayo anogona kushambadzira pane iyo inowanzoitika chikamu chemafuta nemvura, ichigadzira iyo yakaonda molecular layer uye kuderedza kusawirirana pakati pezvikamu zviviri. Ndokunge, iyo oleophic chikamu chemorekuru yemafuta uye elsififier iri kune rimwe divi, uye iyo hydrophic chikamu chemamolekhou yemvura uye emulsifier iri kune rumwe rutivi. Uku kudyidzana pakati pezviviri kunokonzeresa shanduko yekunetseka kwekunetseka;

Kune rimwe divi, nekuumba adsorption adsorption pamusoro peiyo madonhwe, inoburitsa donhwe remadonhwe nekugadzikana kwakasimba spatial. Iyo mimwe emulsifiers inowedzerwa, iyo yakakura kuderera kwekunetseka kwekunetseka. Izvi zvinobvumira zvaimbove zvisina kujairika kuti uve wakasanganiswa, uchigadzira homogeneous kuparadzirwa system iyo inoshandura iyo yekutanga mamiriro emuviri, nekukasira kuvandudza chimiro chemukati chechikafu uye nekuwedzera kunaka kwayo.
Hydrophilic uye oleophilic quilibrium kukosha

Kazhinji. Kuti aratidze iyo hydrophilic uye lipophilic chiyero che emulsifiers, hlb kukosha (hydrophilic lipeilic balance Kune akasiyana siyana ekuverenga nzira dzeHLB kukosha,

Kusiyana formula: hlb = hydrophilikuti ye hydrophilic group - hydrophotic yeboka revaLipeilic

Ratio formula: hlb = hydrophilikuti ye hydrophilic group / hydrophobicity yeOleophilic Boka

Iko kukosha kweHLB yeemulsifier yega yega kunogona kutsanangurwa nenzira dzekuedza. Kuti uwane emulsifiers ne 100% Lipeilipity, yavo HLB iri 0 (inomiririrwa neiyo 100% hydrophilikuts,, yakakamurwa muzvikamu makumi maviri zvakaenzana kuratidza simba renydrofironi yavo uye oleofiicity. Iyo yakakura iyo HLB kukosha, iyo yakasimba iyo hydrofiripi, uye diki iyo HLB kukosha, iyo yakasimba iyo oleoficity.

Ruzhinji rwechirume rwechidariki has non-ionic surfers Iyo HLB kukosha kweionic surfachers ndeye 0-40. Naizvozvo, emulsifiers ine HLB tsika <10 inonyanya kuve lipophic, nepo emulsifiers neHLB kukosha ≥ 10 vane hydrophilic hunhu.

Ye emulsifiers yakasanganiswa, yavo HLB tsika ine zvinowedzera zvivakwa. Naizvozvo, kana maviri kana anopfuura emulsifiers akasanganiswa uye anoshandiswa, iyo HLB kukosha kweiyo emulsifier inosanganiswa inogona kuverengerwa zvichienderana nechikamu chemulsifier yega yega.

Hlba, b = hlba · a% + hlbb b%

Mune formula,

Hlba, B ndiyo HLB kukosha kwe emulsifier a, b yakasanganiswa pamwe chete;

HLBB uye HLBB ndeye HLB tsika dze emulsifiers A uye B, zvichiteerana;

A% uye b% ndiyo chikamu checerenti e A uye B mune yakasanganiswa emulsifier, zvichiteerana (Iyi formula inoshanda kune isiri-ionic emlsifiers).
Nzira dzekugadzirira uye kufurira zvinhu zve emlsifiers

Pane nzira ina dzekugadzirira eMulsifiers, iyo yakaoma Gel nzira, yakanyorova Gel nzira, yemafuta-mvura-yemvura-yemvura nhamba yekusanganisa, uye nzira yemuchina.

Dry Dry Nzira, iyo inosanganisira kuwedzera mvura kune chikamu chemafuta chine emulsifiers. Munguva yekugadzirira, iyo yerabha yerabha (emulsifieri) inotanga kusanganisa zvakanyanya nemafuta, imwe huwandu hwemvura inowedzerwa, ivhu uye rakapetwa mu colostrum, uye ndokuzorwiswa nemvura kusvika kune yakazara yakazara.

Wet Gel nzira, iyo inosanganisira kuwedzera mafuta kune chikamu chemvura chine emulsifiers. Munguva yekugadzirira, gel (emulsifieri) inotanga kunyungudutswa mumvura kuti iite slurry sechiputi chemvura. Zvadaro, chikamu chemafuta chinowedzerwa kune chikamu chemvura mumatanho, pasi muColastrum, uye mvura inowedzerwa kune iyo yakazara huwandu.

Sanganisa mafuta uye zvikamu zvemvura uye uvape kune emulsifier, kusanganisa imwe huwandu hwemafuta nemvura. Grind Arabic Gum mudhiri, wobva wakurumidza kugeda-geda mvura-yemvura muColastrum, uye kudzima nemvura.

Kugadzirira kwe emulsifiers kunonyanya kusanganisira zvinwiwa zviviri, uye kunaka kwemutemo kune kukosha kwakakosha pamhando ye emulsion.

Zvinhu zvinokanganisa emulsificial chinonyanya kusanganisira kushushikana kwekunetseka, viscosity uye tembiricha, nguva yekumberi, uye huwandu hwe emulsifier. Emulsifiers iyo inogona kuderedza zvakanyanya kusanzwisisika kwekunetseka kunowanzo kusarudzwa; Iyo yakanyanya kukodzera emulsion tembiricha ye emulsifiers iri kutenderera 70 ℃. Kana isiri-ionic surachers inoshandiswa se emlsifiers, tembiricha yemumhanzi haifanire kupfuura yavo yepamusoro tembiricha; Iyo mimwe elmifigers inoshandiswa, iyo yakawandisa emulsion yakaumbwa.
