Margarine bụ ihe eji dochie anya bọta nke sitere na mmanụ ihe oriri, abụba anụmanụ ma ọ bụ ebe abụba ndị ọzọ. Usoro mmepụta ya na akụrụngwa nhazi ya etoola nke ukwuu mgbe ọtụtụ afọ nke mmepe gasịrị. Ihe na-esonụ bụ usoro nhazi zuru ezu na ntinye nke akụrụngwa isi:

I. Usoro mmepụta nke Margarin

1. Nkwadebe ihe eji eme ihe

• Isi akụrụngwa:

o Mmanụ (ihe dịka 80%): dị ka mmanụ nkwụ, mmanụ soybean, mmanụ rapeseed, mmanụ aki oyibo, wdg, nke dị mkpa ka a nụchaa (de-gumming, de-acidification, de-coloring, de-odorization).

o Usoro mmiri (ihe dị ka 15-20%): mmiri ara ehi amịpụtara, mmiri, nnu, emulsifiers (dị ka lecithin, mono-glyceride), ihe nchekwa (dị ka potassium sorbate), vitamin (dị ka vitamin A, D), ekpomeekpo, wdg.

o mgbakwunye: agba (β-carotene), acidity regulator (lactic acid), wdg.

2. Ngwakọta na emulsification

• Usoro mmanụ na ngwakọta mmiri:

o The mmanụ na-adọ (mmanụ + mmanụ-soluble mgbakwunye) na-ewe iwe 50-60 ℃ na gbazee.

o The mmiri na-adọ (mmiri + mmiri-soluble mgbakwunye) na-ekpo ọkụ na igba ogwu (pasteurization, 72 ℃ / 15 sekọnd).

o A na-agwakọta akụkụ abụọ ahụ n'ụzọ kwesịrị ekwesị, na emulsifiers (dị ka mono-glyceride, soy lecithin) na-agbakwunye, na emulsion otu (mmiri na mmanụ ma ọ bụ mmanụ n'ime mmiri ụdị) na-etolite site na mkpali ọsọ ọsọ (2000-3000 rpm).

3. Ngwa ngwa jụrụ & crystallization (Igodo Nzọụkwụ)

• Ngwa ngwa ngwa ngwa: A na-eme ka emulsion dị ngwa ngwa na 10-20 ℃ site na onye na-ekpo ọkụ na-ekpo ọkụ (SSHE), na-eme ka kristal nke mmanụ na-emepụta β' kristal ụdị (isi ihe dị mma).

• Ịkpụzi: A na-akpacha abụba siri ike nke dị obere site na kneader (Pin Worker) na 2000-3000 rpm iji mebie nnukwu kristal ma mepụta usoro netwọkụ dị mma na nke edo, na-ezere mmetụta dị egwu.

4. Mature na nkwakọ ngwaahịa

• Mature: A na-ahapụ ya ka ọ guzoro na 20-25 ℃ maka awa 24-48 iji mee ka ihe owuwu kristal guzosie ike.

• Nkwakọ ngwaahịa: A na-ejupụta ya dị ka ngọngọ, iko, ma ọ bụ ụdị ịgba, ma chekwaa ya na refrigeration (ụfọdụ margarine dị nro nwere ike ịchekwa n'ime ụlọ okpomọkụ ozugbo).

II. Ngwa Nhazi Isi

1. Ngwa ọgwụgwọ tupu oge eruo

• Ngwá ọrụ na-edozi mmanụ: centrifuge degumming, de-acidification tower, de-coloration tank, de-odorization tower.

• Ngwá ọrụ nhazi nke mmiri: igwe pasteurization, homogenizer dị elu (nke a na-eji maka mmiri ara ehi ma ọ bụ mmiri na-emepụta ihe).

2. Ngwa emulsification

• Emulsion tank: igwe anaghị agba nchara na-akpali akpali na kpo oku ọrụ (dị ka paddle ma ọ bụ turbine ụdị stirrer).

• homogenizer elu-nrụgide: ọzọ nụchaa emulsion ụmụ irighiri mmiri (nrụgide 10-20 MPa).

3. Ngwa ngwa ngwa jụrụ oyi

• Ihe ngbanwe ọkụ dị n'elu elu (SSHE):

o Ngwa ngwa dị jụụ ka ọ bụrụ ọnọdụ jụrụ oyi, jiri scraper na-atụgharị iji gbochie ịchacha.

Ụdị ụdị: Gerstenberg & Agger (Denmark), Alfa Laval (Sweden), SPX eruba (USA), Shiputec (China)

• Onye ọrụ pin:

o Kwachaa abụba ahụ site na ọtụtụ ntụtụ iji jikwaa nha kristal.

4. Ngwa nkwakọ ngwaahịa

• Igwe na-ejuputa akpaaka: maka ngọngọ (25g-500g) ma ọ bụ ngwugwu gbọmgbọm (1kg-20kg).

• Ahịrị nkwakọ ngwaahịa na-adịghị mma: dabara adaba maka ngwaahịa dị ogologo ndụ (dị ka margarine mmiri na-agwọ UHT).

III. Usoro dị iche iche

1. Margarine dị nro: Ọnụ ọgụgụ dị elu nke mmanụ mmiri mmiri na mmanụ (dị ka mmanụ sunflower), ọ dịghị mkpa maka ịkpụzi ngwa ngwa jụrụ oyi, kpọmkwem homogenized na ngwugwu.

2. Margarine dị ala: Ọdịnaya abụba 40-60%, na-achọ ịgbakwunye ihe ndị na-emepụta ihe (dị ka gelatin, starch gbanwetụrụ).

3. Margarine sitere na osisi: Usoro mmanụ osisi niile, enweghị trans fatty acids (gbanwee ebe agbaze site na mgbanwe ester ma ọ bụ teknụzụ fractionation).

IV. Isi ihe njikwa ogo •

Ụdị kristal: Ụdị kristal β' (dị elu karịa ụdị β kristal) chọrọ njikwa ọnụ ọgụgụ nkwụsị na ngwakọta ike.

• Nchekwa microbial: Usoro mmiri mmiri kwesịrị ka ekpochapụ ya nke ọma, yana pH kwesịrị ịhazi n'okpuru 4.5 iji gbochie nje bacteria.

• Nkwụsi ike oxidation: Tinye antioxidants (dị ka TBHQ, vitamin E) iji zere mmetọ ion ígwè.

Site na nchikota nke usoro na akụrụngwa ndị a dị n'elu, ude arụrụ arụ nke ọgbara ọhụrụ nwere ike ime ka uto nke bọta na-ezute ihe ahụike chọrọ dị ka kọlestrọl dị ala na abụba juru eju. Ekwesịrị imezi usoro na usoro a kapịrị ọnụ dabere na ntinye ngwaahịa (dịka maka ịsa achịcha ma ọ bụ maka itinye n'elu nri).
