Imajarini ithatha indawo yebhotolo eyenziwe ngeoyile yemifuno, ngamafutha ezilwanyana okanye eminye imithombo yamafutha. Inkqubo yayo yokuvelisa kunye nezixhobo zokusebenza ziye zavuthwa kakhulu emva kweminyaka yophuhliso. Oku kulandelayo yinkqubo eneenkcukacha yokuhamba kunye nokuqaliswa kwezixhobo eziphambili:

I. Inkqubo yeMveliso yeMargarin

1. Ukulungiswa kwezinto ezikrwada

• Iimathiriyeli ekrwada eziphambili:

o I-oyile (malunga nama-80%): njengeoli yesundu, i-oyile yeembotyi zesoya, i-oyile ye-rapeseed, i-oyile yekhokhonathi, njl., ezifuna ukucokiswa (i-de-gumming, de-acidification, de-coloring, de-odorization).

o Inqanaba lamanzi (malunga ne-15-20%): ubisi oluncibilikisiweyo, amanzi, ityuwa, izinto zokuthambisa (ezifana ne-lecithin, i-mono-glyceride), izigcina-lwazi (ezifana ne-potassium sorbate), iivithamini (ezifana ne-vitamin A, D), iziqholo, njl.

o Izongezo: umbala (β-carotene), isilawuli se-asidi (i-lactic acid), njl.

2. Ukuxuba kunye ne-Emulsification

• Isigaba se-oyile kunye nesigaba samanzi sokuxuba:

o Isigaba se-oyile (i-oyile + izongezo ze-oyile-enyibilikayo) ifudunyezwa kwi-50-60 ℃ kwaye iyanyibilika.

o Inqanaba lamanzi (amanzi + izongezo ezinyibilikayo emanzini) ziyafudunyezwa kwaye zifakwe iintsholongwane (i-pasteurization, 72℃/15 imizuzwana).

o Izigaba ezibini zixutywe ngokulinganayo, kwaye i-emulsifiers (efana ne-mono-glyceride, i-soy lecithin) yongezwa, kunye ne-emulsion efanayo (i-oil-in-oil okanye i-oil-in-water-type) yenziwe nge-high-speed stirring (2000-3000 rpm).

3. Ukupholisa ngokukhawuleza kunye nokucwebezela (Inyathelo eliPhambili)

• Ukupholisa ngokukhawuleza: I-emulsion ipholiswa ngokukhawuleza ukuya kwi-10-20℃ ngokusebenzisa isitshintshi sobushushu esikhutshiweyo (SSHE), ebangela ukuba i-crystallization ye-oyile yenze i-β' crystal form (isitshixo kwi-texture ecolekileyo).

• Ukubumba: Amafutha asele eqinile achetywa ngoomatshini nge-kneader (I-Pin Worker) nge-2000-3000 rpm ukuze kuqhekezwe iikristale ezinkulu kwaye zenze ulwakhiwo oluhle kunye nolufanayo lwenethiwekhi yamanqatha, kuthintelwa ukuvakala kwegritty.

4. Ukuvuthwa kunye nokuPakisha

• Ukuvuthwa: Kushiywe ukuma kwi-20-25℃ kwiiyure ezingama-24-48 ukuzinzisa ubume bekristale.

• Ukupakishwa: Izaliswa njengeebloko, iikomityi, okanye uhlobo lwesitshizi, ize igcinwe efrijini (enye imajarini ethambileyo inokugcinwa kwiqondo lobushushu begumbi ngokuthe ngqo).

II. IsiXhobo sokuLungiselela uNdoqo

1. Izixhobo zoNyango lwangaphambili

• Izixhobo zokusulungekisa i-oyile: i-centrifuge yokucoca i-oyile, itower yokususa ubumuncu, itanki yokususa umbala, inqaba yokuthomalalisa ivumba.

• Izixhobo zokulungisa isigaba samanzi: umatshini wokucoca i-pasteurization, i-homogenizer yoxinzelelo oluphezulu (esetyenziselwa ubisi okanye i-homogenization yesigaba samanzi).

2. Izixhobo zokuSebenzisa

• Itanki ye-emulsion: itanki yentsimbi engatyiwayo enemisebenzi yokuvuselela nokufudumeza (efana nokubheqa okanye uhlobo lwe-injini yokushukuma).

• I-homogenizer yoxinzelelo oluphezulu: ngakumbi ukucokisa amaconsi e-emulsion (uxinzelelo lwe-10-20 MPa).

3. Izixhobo zokupholisa ngokukhawuleza

• IsiTshintshiselwano soBubushushu phezu komhlaba (SSHE):

o Iphole ngokukhawuleza ukuya kwindawo yokukhenkceza, kunye nescraper ejikelezayo ukuthintela ukunyuswa.

o Iimpawu eziqhelekileyo: Gerstenberg & Agger (Denmark), Alfa Laval (Sweden), SPX flow (USA), Shiputec (China)

• Umsebenzi wePin:

o Cheba amanqatha ngeeseti ezininzi zezikhonkwane ukulawula ubungakanani bekristale.

4. Izixhobo zokupakisha

• Umatshini wokuzalisa ngokuzenzekelayo: kwiibhloko (25g-500g) okanye ukupakishwa komgqomo (1kg-20kg).

• Umgca wokupakisha ongasebenziyo: ulungele iimveliso ezihlala ixesha elide (ezifana nemajarini yolwelo efakwe e-UHT).

III. Iinkqubo ezahlukeneyo

1. IMargarine ethambileyo: Umlinganiselo ophezulu weoli engamanzi kwi-oyile (efana ne-oyile kajongilanga), akukho mfuneko yokubumba okupholisa ngokukhawuleza, i-homogenized ngqo kwaye ipakishwe.

2. I-Margarine enamafutha aphantsi: I-Fat content 40-60%, ifuna ukongeza i-agent e-thickening (njenge-gelatin, isitashi esilungisiweyo).

3. IMargarine esekelwe kwizityalo: Ifomula yeoli yezityalo zonke, akukho trans fatty acids (lungisa indawo yokunyibilika ngokusebenzisa i-ester exchange okanye iteknoloji yefraction).

IV. Amanqaku aphambili olawulo lomgangatho •

Ifom yeCrystal: Ifom ye-β' crystal (iphezulu kune-β crystal form) ifuna ulawulo lwezinga lokucima kunye nokuxubana.

• Ukhuseleko lweMicrobial: Inqanaba lokumanziswa kwamanzi kufuneka livalwe ngokungqongqo, kwaye i-pH kufuneka ihlengahlengiswe ngaphantsi kwe-4.5 ukunqanda ibhaktheriya.

• Ukuzinza kwe-Oxidation: Yongeza i-antioxidants (efana ne-TBHQ, i-vitamin E) ukuphepha ukungcoliswa kwe-ion yensimbi.

Ngokudityaniswa kwezi nkqubo zingentla kunye nezixhobo, ikhrimu eyenziweyo yanamhlanje inokuxelisa incasa yebhotolo ngelixa ihlangabezana neemfuno zempilo ezifana ne-cholesterol ephantsi kunye namafutha asezantsi. Ifomula ethile kunye nenkqubo kufuneka ihlengahlengiswe ngokwendawo yemveliso (efana nokubhaka okanye ukusetyenziswa kwindawo yokutya).
