Horumarka heerka nololeed ee dadka, shuruudaha macaamiisha ee cuntada kuma koobna oo kaliya qiimaha nafaqada ee macquulka ah, laakiin sidoo kale waxay u baahan yihiin cunto si ay u yeelato tayada lagu qanco ee sifooyinka dareenka sida muuqaalka, midabka, udgoonka, dhadhanka, viscosity, freshness, iwm.

Emulsifiers, sida cuntada lagu daro ee qaboojinta, ayaa door muhiim ah ka ciyaara warshadaha cuntada. Aynu eegno habka ficilka emulsifiers!

Emulsion

Emulsion-ka caadiga ah ee cuntadu waxa uu ka kooban yahay biyo ama xalal aqueous, oo si wada jir ah loogu yeero wejiga hydrophilic; Marxaladda kale waa weji dabiici ah oo aan la jaanqaadi karin biyaha, sidoo kale loo yaqaan wajiga lipophilic. Laba dareere ah oo aan la isku dayin, sida biyaha iyo saliidda, waxay samayn karaan laba nooc oo emulsions ah marka la isku daro, kuwaas oo kala ah biyaha saliidda (O/W) iyo biyaha saliidda (W/O) emulsion.

Biyaha ku jira emulsion saliidda, saliidda waxay u kala firdhisaa sidii dhibco yaryar oo biyo ah, oo leh dhibco saliideed oo ah wejiga firdhiya iyo biyuhu sida dhexdhexaadiyaha kala firdhiya. Tusaale ahaan, caanaha lo'du waa emulsion O/W; Biyaha ku jira emulsions saliidda, liddi ku ah waa run. Biyaha waxay u kala firdhiyaan sidii dhibco yaryar oo saliidda ku jira, oo leh biyuhu sida wejiga firdhiya iyo saliidda dhexdhexaadka ah ee kala firdhiya. Tusaale ahaan, subagga macmalka ah waa nooc ka mid ah emulsion W/O.

Habka ficilka emulsifiers

Emulsifiers-yada cuntada, oo sidoo kale loo yaqaanno surfactants, waa maaddooyin u beddela dareeraha aan la taaban karin wejiyada si isku mid ah u kala firdhiyey (emulsions). Marka lagu daro cuntada, waxay si weyn u yareeyn karaan xiisadda isdhexgalka ee u dhexeeya saliidda iyo biyaha, taas oo u oggolaanaysa saliidaha aan la taaban karin (walxaha hydrophobic) iyo biyaha ( walxaha hydrofilic) si ay u sameeyaan emulsions xasilloon sida cunto lagu daro.

Dhinaca kale, emulsifiers waxay sameeyaan lakab molecular oo khafiif ah oogada wejiga ee iska caabbinta leh, hoos u dhigista tamarta xorta ah ee dusha sare ee nidaamka oo dhan iyo samaynta isdhexgal cusub. Emulsifier molecules waxay leeyihiin kooxo hawleed hydrophilic iyo oleophilic, kuwaas oo ku dhajin kara dusha wajiga saliidda iyo biyaha, samaynta lakabka unugyada khafiifka ah iyo yaraynta xiisadda isdhexgalka ee labada weji. Taasi waa, qaybta oleophilic ee molecule saliidda iyo emulsifier-ku waxay ku yaalaan hal dhinac, qaybta hydrophilic ee molecule biyaha iyo emulsifier ayaa dhinaca kale ah. Is dhexgalka labadan ayaa keenaya isbeddel ku yimaada xiisadda wejiga;

Dhanka kale, adoo samaynaya lakab ilaalin ah oo ilaalin ah oo ku yaal dusha sare ee dhibicda, waxay siinaysaa dhibicda xasilloonida meel adag. Mar kasta oo emulsifiers lagu daro, way sii weynaanaysaa hoos u dhaca xiisadda labada waji. Tani waxay u oggolaanaysaa walxaha aan hore loo dhaafin inay isku dhafan yihiin, samaynta nidaam kala firdhisan oo isku mid ah oo beddela xaaladda jireed ee asalka ah, taas oo hagaajinaysa qaabka gudaha ee cuntada iyo kor u qaadida tayada.
Hydrophilic iyo oleophilic dheelitirnaanta qiimaha

Guud ahaan, emulsifiers leh hydrophilicity xoog leh waxay sameeyaan emulsions saliid/biyaha, halka emulsifiers leh hydrophilicity xoog leh ay sameeyaan emulsions biyo/saliid. Si loo muujiyo dheelitirka hydrophilic iyo lipophilic ee emulsifiers, qiimaha HLB (qiimaha dheelitirka lipophilic lipophilic) ayaa badanaa la isticmaalaa, iyo qiimaha HLB waxaa loo isticmaalaa in lagu matalo hydrophilicity emulsifiers. Waxaa jira habab xisaabin kala duwan oo loogu talagalay qiimaha HLB,

Qaacidada kala duwanaanshiyaha: HLB=hydrophilicity ee kooxda hydrophilic - hydrophobicity ee kooxda lipophilic

Qaacidada saamiga: HLB=hydrophilicity ee kooxda hydrophilic/hydrophobia ee kooxda oleophilic

Qiimaha HLB ee emulsifier kasta waxaa lagu go'aamin karaa habab tijaabo ah. Emulsifiers leh 100% lipophilicity, HLBkoodu waa 0 (oo ay matalaan paraffin wax), kuwa leh 100% hydrophilicity, HLB waa 20 (oo ay matalaan potassium oleate), oo loo qaybiyay 20 qaybood oo siman si ay u muujiyaan xoogga hydrophilicity iyo oleophilicity. Inta uu bato qiimaha HLB, waa uu sii xoogaysanayaa biyo-baxa, iyo inta yar ee qiimaha HLB, ayaa sii xoogaysanaya oleophilicity.

Inta badan emulsifiers la cuni karo waa kuwa aan-ionic ahayn oo leh qiyamka HLB ee u dhexeeya 0 ilaa 20. Qiimaha HLB ee kala duwan iyo sifooyinka la xidhiidha emulsifiers-ka aan-ionic ahayn ayaa lagu muujiyay shaxda; Qiimaha HLB ee surfactants ionic waa 0-40. Sidaa darteed, emulsifiers leh qiyamka HLB<10 waa inta badan lipophilic, halka emulsifiers leh qiimayaasha HLB ≥ 10 ay leeyihiin sifooyin hydrophilic.

Emulsifiers isku dhafan, qiyamkooda HLB waxay leeyihiin sifooyin lagu daro. Sidaa darteed, marka laba ama in ka badan emulsifiers la isku daro oo la isticmaalo, qiimaha HLB ee emulsifier-ga isku dhafan waxaa lagu xisaabin karaa iyadoo lagu salaynayo jajabka tirada emulsifier kasta ee ka kooban:

HLB,b =HLBA%+HLBb·B%

Qaacidada,

HLB, b waa qiimaha HLB ee emulsifier a, b la isku daray;

HLB iyo HLBb waa qiyamka HLB ee emulsifiers a iyo b, siday u kala horreeyaan;

A% iyo B% waa boqolleyda ka kooban a iyo b ee emulsifier-ga isku qasan, siday u kala horreeyaan (qaabkani waxa uu khuseeyaa emulsifiers-ka aan-ionic-ka ahayn).
Hababka diyaarinta iyo arrimaha saamaynta leh ee emulsifiers

Waxaa jira afar hab oo loo diyaariyo emulsifiers, kuwaas oo kala ah habka jel engegan, habka jel qoyan, habka isku dhafka saliidda iyo biyaha, iyo habka farsamada.

Habka jel qalalan, kaas oo ku lug leh ku darida biyaha wejiga saliidda ee ka kooban emulsifiers. Inta lagu jiro diyaarinta, budada caagga ah (emulsifier) ​​ayaa marka hore si siman loogu qasaa saliidda, qadar cayiman oo biyo ah ayaa lagu daraa, la miiray oo lagu darey dambarka, ka dibna lagu qasi karo biyo ilaa qadar buuxa.

Habka jel qoyan, kaas oo ku lug leh saliid lagu daro wejiga biyaha oo ay ku jiraan emulsifiers. Inta lagu jiro diyaarinta, jel (emulsifier) ​​ayaa marka hore ku milmay biyaha si ay u sameeyaan slurry sida wajiga biyaha. Kadibna, wajiga saliidda waxaa lagu daraa marxaladda biyaha marxalado, oo la geliyo dambar, biyahana waxaa lagu daraa qadar buuxa.

Isku qas wejiyada saliidda iyo biyaha oo ku dar emulsifier-ga, isku qas xaddi saliid iyo biyo ah. Ku shiidid xanjo Carabi hoobiye, ka dibna si degdeg ah u shiid isku dhafka saliidda iyo biyaha dambarka, oo ku qas biyo.

Diyaarinta emulsifiers inta badan waxay ku lug leedahay emulsification laba dareere, iyo tayada emulsification waxay saameyn weyn ku leedahay tayada emulsion-ka.

Qodobbada saameeya emulsification inta badan waxaa ka mid ah xiisadda wajiga dhexdooda, viscosity iyo heerkulka, wakhtiga emulsification, iyo qadarka emulsifier ee la isticmaalo. Emulsifiers si weyn u yarayn kara xiisadda wejiga ayaa guud ahaan la doortay; Heerkulka ugu habboon emulsifiers ee emulsifiers waa qiyaastii 70 ℃. Haddii surfactants non-ionic loo isticmaalo emulsifiers ahaan, heerkulka emulsification waa in aanu ka badan heerkulka sare; Inta badan ee emulsifiers la isticmaalo, emulsion-ka ayaa aad u xasilan.
