Chitsanzo cha CMC mu Acid mkaka wa acid

1. Maziko azomwezi

Itha kuwoneka kuchokera pamlingo wa hydrogen (Na +) pa cmc ndiosavuta kufooketsa mu mawonekedwe a anion mu anion, ndiye kuti ali ndi vuto lalikulu ndipo ali ndi mphukira. Pamene PH of protein ndiyotsika kuposa malo a isooelertc, kuthekera kwake kumangiriza - gulu la proton ndi lalikulu kwambiri kuposa luso la -Nh3 + kuti ipereke mlanduwu. Mu mkaka, 80% ya mapuloteni ndi milandu, ndipo malo a isoelert ali pafupi 4.6, ndi PH of General Filimu Amamwa khalidwe.

2. Njira yolimbikitsidwa ya acidic mkaka

(1) Njira yoyambira yophatikizidwa mkaka wa acidic (malinga ndi 1000Kg):

Mkaka watsopano (mkaka wathunthu ufa) 350 (33) kg
Oyera shuga 50kg
Wosautsa wotsekemera (nthawi 50) 0.9kg
CMC 3.5 ~ 6KG
Monoglycer 0.35kg
Sodium citrate 0.8kg
Citric acid 3kg
Lactic acid (80%) 1.5kg

Zindikirani:

1) Mphamvu ya mkaka imatha kusinthidwa ndi mapuloteni a hydrolyzid, kuwongolera mapuloteni ≥ 1%.
2) Acidity yomaliza ya mankhwalawa imayendetsedwa mozungulira 50-60 ° t.
3) Kusungunuka kumayendera 7.5% mpaka 12%.

.
Mkaka wamphamvu 350 ~ 600kg
Oyera shuga 60kg
Wosautsa wowonda (nthawi 50) 1kg
CMC 3.2 ~ 8kg
Monoglycer 0.35kg
Sodium citrate 1kg
Kuchuluka kwa acid a citric acid
Chidziwitso: Gwiritsani ntchito citric acid yankho kuti musinthe acidity mkaka, ndipo acidity yomaliza ya mankhwalawa imayendetsedwa pafupifupi 60-70 ° T.

3. Mfundo zazikuluzikulu za kusankha kwa CMC

FH9 ndi FH9 yowonjezera (FVH9) imasankhidwa nthawi zambiri mumamwa zophatikizika. FH9 ili ndi kukoma kwamphamvu, ndipo kuchuluka kwake ndi 0,35% mpaka 0,5%, pomwe FH9 yowonjezera imakhala yotsitsimula ndipo imathandizanso kukulitsa kusintha, ndipo kuchuluka kwake ndi 0,45%.

Lactic Acid mabakiteriya nthawi zambiri amasankha Fl100, FH9 ndi FH9 Super (wopangidwa ndi njira yapadera). Fl100 nthawi zambiri imapangidwa ndi zinthu zokhala ndi kukoma kwa alumali. Zowonjezera ndi 0.6% mpaka 0.8%. FM9 ndiye chinthu chogwiritsidwa ntchito kwambiri. Kusasinthika kumakhala koyenera, ndipo malonda amatha kukwaniritsa moyo wautali. Ndalama zowonjezera ndi 0.45% mpaka 0.6%. Chogulitsa cha FH9 Super Wamcrust Lactic Lactic acid Darteria acid ndi chovuta koma osati mafuta koma osati mafuta, ndipo ndalama zowonjezerazo zitha kukhala zazing'ono, ndipo mtengo wake ndi wotsika. Ndioyenera kupanga mafuta a lactic acid a acid. , kuchuluka kwake ndi 0,45% mpaka 0.6%.

4. Momwe Mungagwiritsire Ntchito CMC

Kusungunuka kwa CMC: Kuzindikira nthawi zambiri kumasungunuka mu mankhwala a 0,5% -2%. Ndikofunika kusungunuka ndi chosakanizika kwambiri. CMC itasungunuka pafupifupi mphindi 15-20, kudutsa mu mphero ya colloid ndikuzizirala mpaka 2040 ° C pogwiritsa ntchito pambuyo pake.

5. MALANGIZO AMAYESA MU NTHAWI YA Acidic mkaka wakumwa

Ubwino wa mkaka waiwisi (kuphatikizapo mkaka wophatikizidwa): mkaka wa antigitics, mkaka wa mastitis, colostrum, ndi mkaka womaliza suyenera kupanga madzi acidi acidic. Zolinga zake za mapuloteni amkaka anayi a mkaka adasintha kwambiri. Kutsutsa, kukana maciri, ndipo kukana mchere kukananso ndi osauka, ndipo amakhudza kukoma mkaka.

Kuphatikiza apo, mitundu inayi yamkaka imakhala ndi michere inayi ya ma enzyme (Litase, mapuloteni, ma elzymes awa atsitsimutsidwa mkaka wa 140 ℃ Munthawi yosungirako, mkaka udzawoneka wowawa, wowawa, wosalala, etc., zomwe zimakhudza moyo wa alumali mwachindunji. Nthawi zambiri, ma sekondale 75% ochulukirapo, mayeso owiritsa, pH ndi tumit acidity wa mkaka ungagwiritsidwe ntchito posankha. Mkaka waiwisi, mayeso a 75% ochulukirapo komanso mayeso owiritsa mkaka wabwinobwino ndiosalimbikitsa, PH ili pakati pa 6.4 ndi 6.8, ndipo acidity ndi ≤18 ≤18 ° ​​T. Pamene acidity ndi ° T, mapuloteni mapuloteni imachitika mukawiritsa, ndipo pH imachepera 6.4 imakhala mkaka wambiri kapena mkaka wa acitis.

(1) Malingaliro a chisamaliro mu njira yophatikizira mkaka wa acidic
Kukonzekera kwa yogati: Kukonzekera kwa mkaka wophatikizidwa: Pang'onopang'ono kuwonjezera mkaka madzi otentha a 50-60 ° C Purgle) kamodzi), kuzirala mpaka 40

Konzani njira ya cmc malinga ndi njira ya CMC, iwonjezere mkaka wokonzedwa, uzikani bwino, kenako muyeso wamadzi (kuchotsa madzi (amachotsa madzi a asidi).

Pang'onopang'ono, mosalekeza, komanso kuwonjezera a asidi yothetsera mkaka, ndikumvetsera kuwongolera nthawi ya acid pakati pa 1.5 ndi mphindi. Ngati nthawi yophatikiza acid ndi yayitali kwambiri, mapuloteni amakhala pamalo a isooelertc points kwanthawi yayitali, ndikupangitsa kutsuka kwa protein yayikulu. Ngati ndi lalifupi kwambiri, a acid nthawi ndi yochepa kwambiri, acidity yakomweko ya mkaka ndi okwera kwambiri, ndipo kutanthauzira kwamapuloteni kuli kovuta. Kuphatikiza apo, ziyenera kudziwidwa kuti kutentha kwa mkaka ndi asidi sikuyenera kukhala yayitali kwambiri powonjezera acid, ndipo ndibwino kuwongolera pa 20-25 ° C pakati.

Nthawi zambiri, kutentha kwachilengedwe kwa mkaka kumatha kugwiritsidwa ntchito kwa homogenization, ndipo kupsinjika kumayendetsedwa ku 18-25MPA.

Kutentha Kowiritsa: Zinthu zosasunthika zimagwiritsidwa ntchito ngati 85-90 ° C kwa mphindi 25-30, ndipo zinthu zina zimagwiritsa ntchito kutentha kwa ma ultra-° ° C kwa masekondi 3-5.

.
Yerekezerani mapuloteni amkaka, kuwonjezera ufa wa mkaka kuti mupange mapuloteni a mkaka pakati pa 2,5%, amasinthanitsa ndi mphindi 30, ndikusintha kwa mphindi 15-15, kutembenukira Pakuchotsa, ndikusunga kutentha kosalekeza kwa 41-43 ° C kwa nayonso mphamvu. Pamene acidity mkaka imafika 85-100 ° t, nayonso mphamvu imayimitsidwa, ndipo imakhazikika mpaka 15-20 ° C ndi mbale yozizira kenako ndikuthiridwa mu vat kuti mugwiritse ntchito pambuyo pake.

Ngati mapuloteni omwe ali mu mkaka ali otsika, padzakhala Whey kwambiri mkaka wopondera, ndipo maboti a mapuloteni amawonekera mosavuta. Pasteurization pa 90-95 ° C ndi woyenera kutsuka koyenera kwa mapuloteni ndikusintha mtundu wa mkaka wopindika. Ngati kutentha kwamphamvu kwambiri kumakhala kochepa kwambiri kapena ngati kuchuluka kwa inoculum ndi kochepa kwambiri, nthawi yochitira mphamvu idzakhala motalika kwambiri, ndipo mabakiteriya amakula kwambiri, zomwe zingakhudze kukoma ndi moyo wazomwe zimachitika. Ngati kutentha kumakhala kwakukulu kwambiri kapena kuchuluka kwa inoculum ndikokulirapo, kupesa udzatalika kwambiri, zomwe a Whey adzapangidwira zochulukirapo kapena zopanga mapuloteni zidzapangidwa, zomwe zingakhudze kukhazikika kwa chinthucho. Kuphatikiza apo, masitima a nthawi imodzi amathanso kusankha zingwe, koma zovuta zomwe zili ndi post-acidity ziyenera kusankhidwa momwe zingathere.

Mumalitsa masentimita kwa masentimita kwa 15-25 ° C ndikusakaniza madziwo, ndikugwiritsa ntchito madzi a acid madzi mkaka pang'onopang'ono, mosalekeza (mosasunthika komanso asidi wopopera). Sokani bwino ndikuyika pambali.

Nthawi zambiri, kutentha kwachilengedwe kwa mkaka kumatha kugwiritsidwa ntchito kwa homogenization, ndipo kupsinjika kumayendetsedwa ku 15-20MPA.

Kutentha Kowiriratu: Zinthu zosasunthika zimagwiritsidwa ntchito ngati 85-90 ° C kwa mphindi 25-30, ndipo zinthu zina zimagwiritsa ntchito kutentha kwa ma ultra-° kapena 95-105 ° masekondi 30.
