Sunfower Roj Renining Tshuab

Cov txiaj ntsig ntawm cov txheej txheem deodorization rau qhov zoo ntawm cov roj sunflower

1. Cov nyhuv deodorization ntawm cov nyhuv deodorization ntawm PAEs hauv cov roj sunflower

Raws li lub sijhawm deodorization ntawm 1{{20}}0 min, qhov kev tshem tawm ntawm DBP, DEHP thiab DINP yog 9.4 feem pua, 61.9 feem pua ​​thiab 61.8 feem pua ​​ntawm qhov deodorization kub ntawm 220 degree; Thaum lub deodorization kub tau nce mus rau 240 degree, qhov kev tshem tawm ntawm DBP, DEHP thiab DINP yog 18.7 feem pua, 95.2 feem pua ​​thiab 92.1 feem pua, thiab DMP, DEP thiab BBP yuav luag tag nrho. Txuas ntxiv kom qhov deodorization kub rau 260 degree, DBP, DEHP, DINP tshem tawm tus nqi mus txog 35.7 feem pua, 100 feem pua, 99 feem pua, cov seem seem ntawm 0.151 mg/kg, tsis kuaj, 0.001 mg/kg, feem. nyob rau hauv lub deodorization kub ntawm 260 degree, luv lub sij hawm deodorization rau 80 min, DBP, DEHP, DINP tshem tawm tus nqi ntawm 23.4 feem pua, 71.4 feem pua, 75.3 feem pua, feem. 71.4 feem pua, 75.3 feem pua ​​, DMP, DEP, BBP yuav luag tag tshem tawm; Tom qab ntawd txo lub sijhawm deodorization rau 60 min, DBP, DEHP, DINP tshem tawm tus nqi ntawm 7.7 feem pua, 42.9 feem pua, 36.0 feem pua, cov nyhuv deodorization tsis txaus siab. Los ntawm kev soj ntsuam saum toj no, nws tuaj yeem pom tias DBP, DEHP thiab DINP yog qhov nyuaj rau kev tshem tawm ntau dua li lwm cov khoom, tej zaum vim tias cov ntsiab lus ntawm peb cov khoom hauv cov roj no siab dua thiab qhov kub ntawm qhov kub siab dua, yog li lawv xav tau kub dua. thiab lub sijhawm distillation ntev dua yuav raug tshem tawm.

2. Cov nyhuv deodorization ntawm cov nyhuv deodorization ntawm PAHs hauv cov roj sunflower

Cov ntsiab lus ntawm 16 PAHs nyob rau hauv cov roj sunflower txo nrog qhov nce ntawm deodorization lub sij hawm thiab deodorization kub. Thaum lub sij hawm deodorization ntawm 100 min thiab deodorization kub ntawm 220 degree, qhov kev tshem tawm ntawm BaP thiab PAH4 yog 35.5 feem pua ​​thiab 15.9 feem pua, thiab cov seem seem yog 6.763 thiab 35.896 ug/kg, raws li, BaP mus txog lub teb chaws tus qauv txwv (10 ug / kg), tab sis BaP thiab PAH4 ob leeg tshaj EU txwv (2 thiab 10 ug / kg). Qhov kev tshem tawm BaP thiab PAH4 yog 56.1 feem pua ​​thiab 38.9 feem pua, thiab cov seem yog 4.604 thiab 26.095 ug/kg raws li, BaP tau zoo dua li lub teb chaws tus qauv, tab sis BaP thiab PAH4 tseem tsis tuaj yeem ncav cuag EU txwv; txuas ntxiv kom qhov kub thiab txias mus rau 260 degree, BaP thiab PAH4 tshem tawm tus nqi yog 100 feem pua ​​thiab 82.0 feem pua, BaP thiab PAH4 residues tsis kuaj thiab 7.693 ug/kg raws li. thiab 7.693 ug / kg, ob qho tib si mus txog EU txwv. Nyob rau tib lub sijhawm, nws tuaj yeem pom tias qhov deodorization kub yog 260 degree, txawm tias lub sijhawm deodorization yog luv tshaj 40 min, BaP kuj mus txog lub teb chaws tus qauv txwv. Los ntawm kev soj ntsuam saum toj no, nws tuaj yeem pom tau tias qhov sib thooj deodorization thiab sib sib zog nqus deodorization tej yam kev mob tuaj yeem raug xaiv raws li cov kev txwv sib txawv los coj mus rau hauv tus account qhov zoo deodorization ntawm PAHs thiab tsawg poob ntawm cov as-ham thiab txo lub zog noj. Tag nrho cov deodorization tus nqi ntawm LPAHs yog siab dua li ntawm HPAHs nyob rau hauv txawv deodorization tej yam kev mob vim hais tias lub boiling point ntawm LPAHs yog ze rau lub deodorization kub, thiab nws yog yooj yim mus khiav nrog dej vapor distillation.

3. Cov txiaj ntsig ntawm deodorization tej yam kev mob ntawm cov khoom muaj txiaj ntsig hauv cov roj sunflower

Thaum lub sij hawm deodorization yog 100 min, VE poob tus nqi nce nrog qhov nce ntawm deodorization kub, thiab VE tuav tus nqi yog ntau tshaj 90 feem pua, thaum lub deodorization kub qis dua 230 degree; Thaum lub deodorization kub siab tshaj 230 degree, VE tuav tus nqi tsawg dua 90 feem pua, thiab thaum deodorization kub nce mus txog 270 degree, VE tuav tus nqi txo mus rau 66.2 feem pua. Thaum lub deodorization kub yog 260 degree, VE poob tus nqi nce nrog rau ncua sij hawm deodorization, thiab VE tuav tus nqi txo los ntawm 87.3 feem pua ​​​​rau 63.2 feem pua ​​​​thaum lub sij hawm deodorization tau ncua ntawm 40 min mus rau 120 min. Qhov no tej zaum yuav yog vim qhov kub thiab txias lub sij hawm ntev distillation deodorization ua rau ib feem ntawm cov qauv VE raug rhuav tshem los yog khiav tawm nrog cov deodorized distillate.

4 Cov nyhuv ntawm deodorization tej yam kev mob ntawm fatty acid muaj pes tsawg leeg ntawm sunflower roj

Thaum lub sijhawm deodorization (100 min), cov ntsiab lus ntawm cov roj ntsha trans fatty acids (TFA) nce ntxiv nrog qhov nce ntawm deodorization kub, tshwj xeeb tshaj yog tom qab ntau tshaj 250 degree, cov ntsiab lus ntawm TFA nce sai, thiab cov ntsiab lus ntawm 260 degree yog 1.8 npaug. siab dua li ntawm 250 degree, thiab thaum lub deodorization kub nce mus rau 270 degree, cov ntsiab lus ntawm TFA nce mus rau 1.16 feem pua, uas yog 22.2 npaug ntau dua li ntawm cov roj deodorized. Thiab qhov nce ntawm trans linoleic acid cov ntsiab lus yog qhov tseem ceeb tshaj plaws. Ntawm qhov deodorization kub (260 degree), TFA cov ntsiab lus tau nce ntxiv nrog rau lub sijhawm deodorization, thiab TFA cov ntsiab lus yog 21.2 npaug siab dua li cov roj decolorized ntawm 120 min. Trans fatty acids txo cov khoom noj muaj txiaj ntsig ntawm cov roj noj, txhawb cov hlab ntsha thiab cov hlab ntsha hauv tib neeg, thiab cuam tshuam rau kev loj hlob thiab kev loj hlob [23], yog li deodorization tej yam kev mob ntawm cov roj thiab cov rog yuav tsum tau optimized, thiab cov txheej txheem deodorization nruab nrab yuav tsum tau siv los tiv thaiv. thiab tswj cov tiam ntawm trans fatty acids.

5. Cov txiaj ntsig ntawm deodorization tej yam kev mob ntawm qhov ntsuas zoo ntawm sunflower noob roj

Deodorization ntawm cov roj thiab cov rog tsis tuaj yeem tsuas yog tshem tawm cov ntxhiab tsw hauv cov roj thiab cov rog, ua kom cov pa taws ntawm cov roj thiab cov rog, thiab txhim kho qhov tsw ntawm cov roj thiab cov rog, tab sis kuj txhim kho kev ruaj ntseg, xim thiab zoo ntawm cov roj thiab cov rog.

Nrog rau qhov nce ntawm deodorization kub thiab lub sij hawm deodorization, cov kua qaub ntawm cov roj sunflower maj mam txo, tus nqi peroxide thawj zaug txo qis thiab tom qab ntawd nce, tag nrho cov pa taws tau nce, thiab xim tau sib dua.

Muaj ob lub ntsiab ntawm cov txheej txheem refining tshuab raws li lub hom phiaj zoo rau cov roj refined.
