Additives thiab preservatives siv nyob rau hauv Ice-cream manufacturing

Raws li cov ice cream txav mus rau qhov ntsuas los ntawm tus nqi, tau qis dua hauv cov rog thiab suav nrog huab cua ntau, cov khoom xyaw ntxiv los ua kom tsis txhob poob ntawm creamy kev ntxhib los mos, nplua nuj "lub qhov ncauj", thiab pab kom tag nrho cov huab cua ntxiv whipped.

Emulsifiers xws li monoglyceridesglycerol monostearatethiab lwm yam diglycerides pab kom cov mis nyuj rog hauv kev ncua thiab txwv kev loj hlob ntawm cov dej khov nab kuab. Lwm cov emulsifiers xws lilecithinthiabPolysorbate 80ua cov haujlwm zoo sib xws. Emulsifiers muaj qhov cuam tshuam tseem ceeb ntawm kev ua kom cov roj globules lo ua ke hauv cov saw hlau, tsis yog ntws ua ke hauv cov globules loj, lossis nyob sib cais raws li cov me me. Qhov no ntxiv rau cov qauv ntawm cov dej khov nab kuab thiab cuam tshuam rau kev ntxhib los mos thiab muaj peev xwm sib xyaw cov huab cua rau hauv qhov sib tov.

Cov pos hniav zoo ligum ua, locust taum cov pos hniav, xanthan cov pos, carrageenan, thiab methylcellulose pab tiv thaiv cov dej khov nab kuab los ntawm kev tsim thaum lub sij hawm khov thiab rov khov dua tom qab taug kev los ntawm lub khw muag khoom noj. Lawv kuj muaj "lub qhov ncauj xav" zoo ib yam li cov mis nyuj rog, yog li cov mis nyuj rog tsis nco ntau npaum li cov mis nyuj khov. Zoo li emulsifiers, lawv kuj pab ua kom huab cua nplawm rau hauv kev sib tov. Cov pos hniav khaws cov ice cream los ntawm kev ua grainy vim muaj cov muaju ua los ntawm cov dej khov los yog lactose.

Qee cov ice cream muajsodium citratetxhawm rau txo qhov nyiam ntawm cov rog globules rau coalesce, thiab txo cov protein aggregation. Qhov no ua rau "dej" ice cream. Cov citrates thiab phosphates yog ob qho tib si siv rau cov nyhuv no. Calcium thiab magnesium ntsev muaj qhov sib txawv, ua rau "lub tshuab ziab khaub ncaws" ice cream.

Hauv qab no yog ib daim ntawv teev cov ice cream additives nrog luv luv piav qhia (tsis zoo sab tsom): -

Cov hauv qab no yog cov npe ntawm cov khoom xyaw uas muaj nyob hauv cov khoom lag luam ice cream feem ntau. Npaj kom txaus siab los ntawm qhov pom tseeb tsis muaj kev txhawj xeeb txog kev noj qab haus huv ntawm cov neeg siv khoom. Npaj kom npau taws tias FDA tau pom zoo rau cov khoom xyaw no los muab tso rau hauv peb cov zaub mov kom txaus siab rau kev txhawb nqa cov koom haum ua zaub mov.

Butyraldehydeyog ib tug derivative ntawm butane, siv nyob rau hauv manufacturing plasticizers, alcohols, solvents thiab polymers. Nws muaj almond zoo li tsw thiab siv los ua cov tsw.

Amyl acetate,Feem ntau hu ua txiv tsawb roj, yog siv los ua tus neeg sawv cev flavoring. Nws kuj yog xim thiab lacquer hnyav thiab siv rau hauv kev npaj ntawm penicillin.

Diethyl glycolyog siv nyob rau hauv zus tau tej cov polyester resins thiab plasticizers, thiab yog ib tug xim hnyav. Hauv cov dej khov nab kuab, nws tau siv los ua ib qho pheej yig hloov rau cov qe kom thicken cov khoom. Peb xyoos dhau los nws tau yuam kev siv cov tshuaj paracetamol (acetaminophen) syrup thiab ua rau muaj 25 tus menyuam tuag hauv Bangladesh. Tsib xyoos dhau los, nws tau pom nyob rau hauv luv nqi tshuaj txhuam hniav ua nyob rau hauv Suav teb thiab rub los ntawm lub khw txee hauv Miami, Chaw nres nkoj ntawm Los Angeles & Puerto Rico. Cov kws saib xyuas kev noj qab haus huv tau hu nws tias yog tshuaj lom syrupy thiab ceeb toom tias nws muaj tshuaj lom rau cov menyuam yaus thiab cov neeg mob raum lossis mob siab. "Cov neeg cuav" tau pom tias nws muaj txiaj ntsig zoo los hloov diethylene glycol rau nws cov tshuaj lom neeg cov txheeb ze glycerin vim nws pheej yig dua. CovFDA tau hais tias cov tshuaj hauv ib qho nyiaj twg tsis haum rau kev sivhauv tshuaj txhuam hniav. (Kuv pom nws nthuav tias nws tsis tsim nyog siv rau hauv cov khoom uas tau nti tawm, tab sis ok rau cov khoom noj uas txhob txwm noj)

Aldehyde C -17yog cov kua ua kua siv nyob rau hauv dyes, plastics, roj hmab thiab ua zaub mov flavoring. Kuv tau ua ntau qhov kev tshawb nrhiav nrhiav aldehyde tshwj xeeb no tab sis nrhiav tsis tau nws nyob qhov twg, txawm hais tias muaj ntau hauv online hais txog aldehydes feem ntau, nrog rau cov hom tshwj xeeb. Rau kuv… tej yam uas yuav ua tau ob npaug li cov khoom noj flavoring nrog rau hauv kev tsim cov yas thiab roj hmab, tsis yog ib yam uas kuv xav tias kuv xav noj.

Piperonalyog siv nyob rau hauv qhov chaw ntawm vanilla raws li ib tug pheej yig hloov tab sis, interestingly, nws yog ib tug natural khoom uas los ntawm vanilla taum. Nws tau teev nyob rau hauv National Library of Medicine HSDB Database li "mob toxic"thiab ib"tib neeg daim tawv nqaij irritant". Lwm yam siv rau nws? Los tua ntshauv. Kuv tsis tuaj yeem xav ntawm lo lus "mob toxic". yuav tsis tuag sai, tab sis nyob rau ntawm ib tug ntau "nruab nrab" pace.

Ethyl Acetateyog cov kuab tshuaj nyob rau hauv coatings thiab inks thiab yog siv rau extraction ntawm fatty cov ntaub ntawv thaum lub sij hawm ua zaub mov. Nws kuj tseem siv los tsim cov pineapple tsw. Cov vapor paub tias ua rau lub ntsws ntev, lub siab, thiab lub plawv puas. MSDS (Cov Ntaub Ntawv Kev Nyab Xeeb Cov Ntaub Ntawv) lees tias muaj tshuaj lom yog tias noj ntau tab sis ceeb toom tias formaldehyde toxicity nce nrog ethyl acetate. Qhov ntawd yuav yog qhov nthuav dav hauv "kev noj haus" ice cream uas siv aspartame, aspartame yog cov tshuaj uas hloov mus rau formaldehyde hauv lub cev. Los yog zoo dua… muaj dej khov ntab ntab nrog cov dej qab zib noj uas muaj formaldehyde los ntawm aspartame!Woo Hoo!!! Cancer Sundae!

Monoglycerides, Diglycerides, & Triglycerides- tag nrho peb yam khoom yog tsim los ntawm fatty acids, thiab tag nrho tej zaum yuav muajcov rog transthaum cov fatty acids no raug mus rau high kub ua. Kev lag luam tsuas yog yuav tsum tau tshaj tawm cov ntsiab lus ntawm cov rog rog los ntawm triglycerides (tsis yog mono lossis di) txawm tias cov roj trans fats tsis tsim nyog thaum mono thiab di tsim.{kev lag luam tab tom ua si nrog qhov ntau thiab tsawg txhawm rau khaws cov roj trans rog hauv qab ½ gram ib qho "kev pabcuam" nyiaj pab kom tsis txhob tau tshaj tawm lawv. Hauv qab ½ sib npaug zero rau kev sau npe.}

Disodium phosphate- MSDS yog qhov tsis muaj txiaj ntsig zoo. Thaj tsis tau paub ntau txog cov tshuaj uas tsis yog nws muaj kev phom sij me ntsis rau ntawm daim tawv nqaij thiab qhov muag, thiab thaum noj thiab nqus tau pa. Cov teebmeem Carcinogenic: tsis muaj Mutagenic Effects: tsis muaj Teratogenic teebmeem: tsis muaj Kev Loj Hlob Toxicity: tsis muaj.Kuv twv tsis paub yog tib yam li kev nyab xeeb thaum nws los txog rau kev ua zaub mov.

Benzyl acetate hmoovyog siv nyob rau hauv xab npum, detergents, xyab, roj, lacquers, polishes, luam ntawv inks thiab raws li ib tug hnyav nyob rau hauv plastics thiab resins. Nws kuj yog siv rau hauv cov khoom noj qab zib. Nws paub tias yog carcinogenic hauv cov nas, ua rau cov qog nqaij hlav hauv ntsws, daim siab thiab plab hnyuv, txawm hais tias nws tau lees tias tsuas muaj 0.1 feem pua ​​​​qhov muaj feem yuav tshwm sim hauv tib neeg. Qhov ntawd yog qhov kev thov nthuav vim tias muaj cov ntaub ntawv me me me me lossis kev tshawb fawb ntev los txiav txim siab txog kev phom sij.

Propylene glycol- ATSDR teev cov tawv nqaij, ob lub raum, tso zis, thiab ua pa ua pa uas cuam tshuam los ntawm cov tshuaj. Nws yog cov kua hluavtaws uas nqus dej thiab siv rau hauv cov khoom noj kom nqus dej ntxiv thiab tswj cov dej noo. Nws yog ib qho hnyav rau zaub mov xim thiab tsw, thiab hauv cov yas thiab xim.
