Cov ntsiab lus ntawm Deodorization txheej txheem
Cov txheej txheem deodorization feem ntau cuam tshuam nrog kev kub siab -kub los ntawm cov roj thiab cov rog. Nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias (240-260 degree) thiab lub tshuab nqus tsev siab (2-5 mmHg), cov ntsiab lus kub hnyiab ntawm cov ntxhiab tsw - ua rau cov khoom siv -xws li aldehydes, ketones, thiab cov roj fatty acids dawb - tau qis dua. Yog li ntawd, cov tshuaj no yog nqa tawm nrog rau lub zog, yog li ua tiav lub hom phiaj ntawm kev tshem tawm cov ntxhiab tsw ntawm cov roj thiab cov rog.
I. Qhov cuam tshuam ntawm Deodorization ntawm Unsaturated Fatty Acids
(I) Qhov tseem ceeb ntawm Unsaturated Fatty Acids
Unsaturated fatty acids yog cov khoom noj khoom haus tseem ceeb ntawm cov roj thiab cov rog. Qee qhov muaj txiaj ntsig zoo rau kev noj qab haus huv ntawm cov hlab plawv, thaum lwm tus koom nrog ntau cov txheej txheem physiological, xws li kev tsim cov cell membranes thiab synthesis ntawm cov tshuaj hormones.
(II) Kev hloov pauv hauv Unsaturated Fatty Acids Thaum Deodorization **
1. Kev pheej hmoo ntawm Oxidation Reactions
• Nyob rau hauv qhov kub ntawm - ib puag ncig kub ntawm cov txheej txheem deodorization, unsaturated fatty acids raug oxidation. Thaum oxidation, unsaturated fatty acids tsim peroxides; tom qab decomposition ntawm cov peroxides no ua rau muaj teeb meem tshuaj -xws li aldehydes thiab ketones- uas tsis yog tsuas yog txo tus nqi noj haus ntawm unsaturated fatty acids tab sis kuj yuav ua rau muaj kev pheej hmoo rau tib neeg noj qab haus huv.
2. Isomerization Reactions
• Qhov kub thiab txias kuj tseem tuaj yeem ua rau isomerization tshwm sim hauv cov roj ntsha tsis txaus. Qhov tshwm sim no tuaj yeem ua rau muaj kev pheej hmoo ntawm cov kab mob plawv. Txawm li cas los xij, thaum ua haujlwm nyob rau hauv zoo - tswj cov xwm txheej, cov txheej txheem deodorization niaj hnub tuaj yeem txo qis ntawm cov tshuaj tiv thaiv isomerization.
II. Kev cuam tshuam rau Fat-Soluble Vitamins
(I) Kev ua haujlwm ntawm Fat-Soluble Vitamins
Vitamin E, muaj nyob rau hauv cov roj thiab rog, ua raws li ib tug haib antioxidant; nws tiv thaiv cov hlwb los ntawm kev puas tsuaj los ntawm cov dawb radicals thiab ua lub luag haujlwm hauv thaj chaw xws li kev tiv thaiv kab mob plawv thiab ncua kev laus. Vitamin K, ntawm qhov tod tes, ua haujlwm tseem ceeb ntsig txog ntshav coagulation thiab kev noj qab haus huv ntawm pob txha; Nws koom nrog hauv kev sib txuas ntawm cov khoom sib txuam thiab ua kom yooj yim rau kev tso cov calcium hauv cov pob txha.
(II) Kev poob thaum lub sij hawm deodorization txheej txheem
1. Poob Vitamin E
• Nyob rau hauv qhov kub thiab txias thiab chav thaum lub sij hawm deodorization txheej txheem, qhov poob ntawm vitamin E tuaj yeem muaj li ntawm 30% mus rau 50%. Qhov kev poob no txo qis lub peev xwm antioxidant ntawm cov roj, ua rau nws yooj yim dua rau oxidation thaum khaws cia thiab siv.
2. Poob Vitamin K
• Txawm li cas los xij, thaum raug rau qhov kub thiab txias ntev ntev, vitamin K kuj tseem poob qis. Yog tias cov txheej txheem tswj tsis txaus, qhov poob ntawm vitamin K yuav tshwm sim ntau dua.
III. Kev cuam tshuam rau Phytosterols
(I) Cov txiaj ntsig ntawm Phytosterols
Phytosterols muaj cov qauv tshuaj zoo ib yam li cov roj cholesterol; Hauv tib neeg txoj hnyuv, lawv sib tw nrog cov cholesterol rau qhov chaw nqus. Qhov kev sib tw no txo qis kev nqus cov roj cholesterol, yog li pab txo qis cov roj cholesterol hauv cov ntshav thiab muab kev tiv thaiv zoo rau cov hlab plawv.
(II) Kev hloov pauv thaum lub sij hawm deodorization txheej txheem
1. Kev poob qis
• Thaum lub sij hawm deodorization, ib qho me me poob ntawm phytosterols tshwm sim. Raws li cov txheej txheem ua kom zoo deodorization, qhov kev poob no tuaj yeem tswj tau li ntawm 10% txog 20%.
2. Muaj peev xwm hloov tau cov khoom
• Ib yam li ntawd, qhov kub ntawm - ib puag ncig yuav muaj peev xwm hloov lub cev thiab tshuaj lom neeg ntawm phytosterols. Yog tias qhov no tshwm sim, nws yuav txo qis lawv cov kev tiv thaiv kev mob plawv.
IV. Kev txhim kho hauv cov txheej txheem deodorization niaj hnub thiab kev khaws cia ntawm cov khoom noj khoom haus
(I) Cov Txheej Txheem Txhim Kho Kev Ntsuas
1. Kev ua kom zoo ntawm qhov ntsuas kub thiab lub sijhawm tswj
• Cov txheej txheem deodorization niaj hnub siv cov ntsuas kub siab tshaj plaws thiab cov tshuab tswj tsis siv neeg kom txo tau lub sijhawm ntawm cov roj raug rau siab - qhov kub thiab txias ib puag ncig, thaum tib lub sijhawm ua kom muaj txiaj ntsig zoo deodorization. Piv txwv li, qee cov txheej txheem deodorization txuas ntxiv tuaj yeem txo lub sijhawm nyob ntawm cov roj hauv lub deodorization ntauwd los ntawm cov tsoos ob peb teev mus rau ib qho mere 30 mus rau 90 feeb; Qhov no ua rau txo qis oxidation ntawm unsaturated fatty acids thiab txo qhov poob ntawm cov khoom noj khoom haus, xws li cov vitamins.
2. Kev txo qis ntawm Oxygen Exposure
• Nitrogen pam tshuab tau muab tso rau hauv lub teeb deodorization. Ua ntej cov roj nkag mus rau hauv cov khoom siv deodorization, huab cua nyob rau hauv lub apparatus yog purged thiab hloov nrog nitrogen; Ntxiv mus, ib tug me me kwj ntawm nitrogen yog tsis tu ncua qhia thoob plaws hauv lub deodorization txheej txheem. Qhov no lub tswv yim zoo txo qhov kev pheej hmoo ntawm cov roj oxidation ntawm qhov kub thiab txias, yog li tiv thaiv cov khoom noj khoom haus xws li unsaturated fatty acids.
3. Kev txais yuav Novel Deodorization Media
• Kev tshawb fawb tam sim no tab tom tshawb nrhiav kev siv cov xov xwm deodorization tshiab los ua lwm txoj hauv kev rau chav ua noj. Cov xov xwm tshiab no tuav lub peev xwm ua rau muaj kev cuam tshuam tsawg dua rau cov roj cov khoom noj khoom haus thaum tseem muaj txiaj ntsig zoo ntawm kev tshem tawm ntxhiab tsw - ua rau muaj tshuaj. Piv txwv li, kev siv cov pa roj carbon dioxide supercritical raws li qhov nruab nrab deodorization tso cai rau cov txiaj ntsig zoo deodorization kom ua tiav nyob rau hauv cov mob me me, uas ua rau muaj kev puas tsuaj tsawg ntawm cov roj cov khoom noj khoom haus.
(II) Kev ua tau zoo ntawm kev khaws cov khoom noj khoom haus
1. Txhim khu kev ruaj ntseg ntawm Unsaturated Fatty Acids
• Los ntawm kev ntsuas kev txhim kho saum toj no, oxidation thiab isomerization tshwm sim ntawm unsaturated fatty acids tuaj yeem tswj tau zoo. Piv txwv li, nyob rau hauv lub optimized deodorization txheej txheem, tiam ntawm unsaturated fatty acid oxidation cov khoom yuav raug txo los ntawm 50% mus rau 70%, thaum lub tsim ntawm * trans * fatty acids kuj yuav khaws cia nyob rau hauv qis qis, yog li zoo dua khaws cia cov khoom noj muaj txiaj ntsig ntawm unsaturated fatty acids.
2. Txo qhov poob rog -Soluble Vitamins
• Hais txog roj- cov vitamins soluble, kev txhim kho deodorization txheej txheem pab txo qhov poob ntawm Vitamin E thiab Vitamin K. Piv txwv li, los ntawm kev siv cov txheej txheem deodorization siab heev ua ke nrog kev noj zaub mov zoo, vitamin E poob tuaj yeem txo qis ntawm 10% thiab 20%, thiab Vitamin K poob tuaj yeem tswj tau li ntawm 5% mus rau 10%. Qhov no ua kom muaj kev tuav pov hwm zoo ntawm cov roj antioxidant zog thiab lwm yam kev ua haujlwm ntawm lub cev.
3. Tiv thaiv kev ua haujlwm ntawm Phytosterols
• Nyob rau hauv kev tiv thaiv ntawm cov txheej txheem deodorization niaj hnub, qhov poob ntawm phytosterols tuaj yeem txo qis ntxiv, thiab lawv lub cev thiab cov khoom siv tshuaj raug khaws cia zoo dua. Qhov no pab txhawb kev muaj peev xwm ntawm phytosterols los tawm tsam lawv cov roj cholesterol-kev nqus- txo qis kev ua haujlwm hauv tib neeg txoj hnyuv, yog li tswj hwm lawv txoj haujlwm tiv thaiv kab mob plawv.
Cov txheej txheem deodorization muaj qee yam cuam tshuam rau cov khoom noj khoom haus ntawm cov roj thiab cov rog- feem ntau cuam tshuam nrog cov oxidation thiab isomerization ntawm unsaturated fatty acids, poob ntawm cov rog- cov vitamins soluble, thiab kev poob qis ntawm phytosterols. Txawm li cas los xij, nrog kev txhim kho txuas ntxiv ntawm cov thev naus laus zis niaj hnub deodorization- dhau los ntawm kev ntsuas xws li kev ua kom zoo ntawm qhov kub thiab txias thiab lub sijhawm tswj, txo qis cov pa oxygen, thiab siv cov tshuaj deodorization tshiab- tam sim no nws muaj peev xwm ua kom muaj txiaj ntsig zoo ntawm kev khaws cov roj cov khoom noj khoom haus thaum ib txhij ua kom muaj txiaj ntsig zoo deodorization.
