Lub active ingredient ntawm mis nyuj thistle
Mis thistle roj cov ntsiab lus ntawm 25% mus rau 30%, ntawm cov unsaturated fatty acid cov ntsiab lus ntawm ntau tshaj 80% .Mis thistle yog muab rho tawm los ntawm defatted pluas mov ntawm daj hmoov los yog crystalline hmoov.
Tam sim no, mis nyuj thistle yog muab rho tawm los ntawm cov roj los ntawm nias, lub ncuav mog qab zib muaj cov roj siab, uas yuav cuam tshuam rau cov txiaj ntsig thiab qhov zoo ntawm cov mis nyuj thistle ntau lawm.
Kev siv butane subcritical low temperature extraction technology los extract mis thistle roj tuaj yeem ua rau qhov tsis txaus ntawm cov txheej txheem tsim khoom tam sim no thiab rho cov roj ntau dua.
Cov txheej txheem ntau lawm yog raws li nram no:
Mis thistle → decontamination softening → Rolling blank → low temperature extraction of butane → crude oil → refining → tiav roj
Txheej txheem piav qhia:
Cov khoom nyoos raug tshem tawm los ntawm lub vibrating npo, thiab tom qab ntawd muab tso rau hauv lub lauj kaub softening los ntawm conveyor.Tom qab ntawd ntxiv ib qho dej, cua sov rau 45 ~ 55 degree thiab tuav rau ib lub sijhawm (kwv yees li 15min) kom soften.Thiab tom qab ntawd dov los ntawm billet dov tshuab, billet thickness ntawm 0.3m, noo noo tswj ntawm li 8%, billet xa mus rau lub subcritical extraction Rhiav.
Cov kuab tshuaj subcritical yog butane, thiab qhov khoob yog muab rho tawm ntawm chav tsev kub, qhov siab ntawm qhov rho tawm yog {{0}}.4 ~ 0.6MPa, qhov kev rho tawm tam sim no yog 4 zaug, thiab cov roj seem mus txog 1.2%. Cov roj crude yog lim, hydrated, deacidified, decolorized, deodorized thiab dewaxed kom tau refined edible roj. Cov mis nyuj khov no kuj yog cov khoom tseem ceeb, uas yog muab rho tawm thiab ntxuav los ntawm acetone thiab lwm cov kuab tshuaj kom tau txais cov khoom silymarin.
Khoom nta:
1. Kev rho tawm tau zoo
High extraction npaum li cas: subcritical extraction technology tau zoo extract lub active Cheebtsam ntawm mis thistle roj, xws li unsaturated fatty acids thiab mis nyuj thistle. Piv nrog rau cov txheej txheem nias ib txwm, qhov kev rho tawm ntawm subcritical extraction yog siab dua, thiab cov roj yam tuaj yeem muab rho tawm ntau dua.
Kev xaiv zoo: Subcritical kua muaj kev xaiv zoo, tuaj yeem tsom mus rau rho tawm cov hom phiaj cov khoom xyaw, txo qhov sib xyaw ntawm impurities, yog li txhim kho cov purity ntawm cov extract.
2. Tiv thaiv cov khoom xyaw nquag
Kev rho tawm qhov kub thiab txias: Cov txheej txheem tshem tawm qhov tseem ceeb yog ua tiav ntawm qhov kub qis, feem ntau yog nyob nruab nrab ntawm 30-50 degree C, uas zam kev puas tsuaj ntawm cov khoom xyaw los ntawm qhov kub thiab txias thiab muaj peev xwm khaws cov as-ham zoo li cov roj tsis muaj roj. acids thiab vitamins nyob rau hauv mis nyuj thistle roj.
Tsis muaj tshuaj lom neeg cov kuab tshuaj residue: cov kuab tshuaj siv rau sub-critical extraction (xws li butane, propane, thiab lwm yam) yog gaseous nyob rau hauv chav tsev kub thiab siab, yooj yim volatile, thiab yuav tsis nyob twj ywm nyob rau hauv lub extract, kom lub purity thiab kev ruaj ntseg ntawm cov extract. .
