Nekuwedzera kuri kuita kudiwa kwevatengi kwemhando yechikafu uye hutano, indasitiri yekuwedzera chikafu iri kusangana nemafungu ehunyanzvi hwekuvandudza tekinoroji. Iine yakasarudzika chimiro chemakemikari uye kuita zvakasiyana-siyana, Sucrose Isobutyrate (SAIB) yave yakakurumbira mbishi zvinhu mumunda wekugadzira chikafu. Uyu musanganiswa we ester musanganiswa wakavakirwa pamusikirwo sucrose haungori nekatatu basa re stabilizer, emulsifier uye thickener, asi zvakare unoratidza yakanakisa yekushandisa inogona muchinwiwa, kubheka, zvigadzirwa zvemukaka uye mimwe minda. Iri bepa richaongorora zvakadzama kuti SAIB inogadzirisa sei nzvimbo yekuwedzera yeindasitiri yechikafu kubva pazvinhu zvitatu: misimboti yehunyanzvi, mamiriro ekushandisa uye maitiro eindasitiri.

Kemikari maitiro uye zvakanakira tekinoroji zveSAIB

1. Molecular chimiro: chiyero chakakwana chechisikigo uye chekugadzira

SAIB inotora sucrose (C??H??O??) semusimboti wayo uye inoumba yakasanganiswa ester chimiro nekutsiva mamwe emapoka ayo masere ehydroxyl (reshiyo yeacetate kune isobutyrate ingangoita 2:6) . Iyi dhizaini inobvumira kuti ive zvese hydrophilic uye lipophilic, uye inogona kutungamirwa pamafuta-mvura interface kudzikamisa iyo yekuparadzira system. Kuenzaniswa nemaemulsifiers echinyakare (akadai semonoglycerides), SAIB ine yakakwira molecular steric hindrance, inoumba bhaisikopo rakaomarara, uye rine acid-alkaline, kunyanya inokodzera chikafu chakanyanya-asidhi kana shuga yakawanda.

2. Zvimiro zvemuviri: Kuchinjika kune akawanda-mamiriro ekugadzirisa

SAIB is a viscous liquid pakamuri tembiricha (fluidity inowedzera zvakanyanya pamusoro pe40 ℃) ine density inosvika 1.146g/mL. Saib inonyungudika mu ethanol, acetone nezvimwe zvinonyungudutsa, asi kwete mumvura. Yayo yakasarudzika rheological properties inoita kuti ishandiswe kwete chete sechigadziro chemvura emulsions, asi zvakare kuwana shanduko kubva kune yakaderera viscosity kuenda kune yakakwirira viscosity nekugadzirisa iyo yekumisikidza kuti isangane nezvinodiwa zvakasiyana-siyana chikafu maumbirwo.

Iwo akakosha mabasa uye mameseji ekushandisa eSAIB mukugadzirisa chikafu

1. Stabilizer: kurebesa hupenyu hwesherufu, chengetedza hunhu hwekunzwa

Muchikafu chemvura chakadai sezvinwiwa zvekabhoni uye muto wemichero, SAIB inochengetedza yunifomu turbidity yechigadzirwa nekudzivisa chikamu chemafuta chinoyangarara uye kugadzika kwezvimedu zvakasimba. Semuyenzaniso, mhando yepasi rese yakatanga "doro-isina sparkling juice" neSAIB (0.14g/kg) pachinzvimbo chechinyakare chingamu chiArabic, hupenyu hwesherufu kubva kumwedzi mitatu kusvika kumwedzi 9, uye kuravira kunowedzera kuzorodza.

tekinoroji nzira: iyo yakakwira molecular huremu hweSAIB (inenge 830-850 g/mol) inoshanda zvakabatana nemapoka epolar kuumba matatu-dimensional network chimiro, iyo inovhara zvinobudirira kuunganidzwa kwezvikamu zvakapararira.

2. Emulsifier: pwanya zvipimo zvechinyakare, vhura iyo itsva formula

HLB kukosha (hydrophilic lipophilic equilibrium value) yeSAIB inogona kugadziriswa nekugadzirisa ester group reshiyo (renji 8-12), zvese kudzikamisa mafuta-mumvura (O/W) emulsions (semuenzaniso, makirimu emiti) uye emvura-mu-mafuta (W/O) masisitimu emafuta (semuenzaniso, mafuta). Muna 2024, kambani inobika chingwa yakatanga "zero trans fatty acid sandwich cake", iyo inoshandisa SAIB kutsiva hydrogenated mafuta emiriwo kuti iwane kuzadza kwakatsetseka uye kwakatsetseka pasina njodzi dzehutano, uye kutengesa kwechigadzirwa kwakawedzera ne35%.

3. Thickener: kuhwina-kuhwina mamiriro ezvese mameseji ekuvandudza uye hutano kukwezva

Pasi pemaitiro eshuga yakaderera uye yakaderera mafuta, SAIB inobhadhara kurasikirwa kwemavara kunokonzerwa nekuderedza shuga nekuwedzera viscosity uye goho kushushikana kwehurongwa. Semuenzaniso, apo 0.5% SAIB yakawedzerwa kune imwe kambani yemukaka "yakakwira protein yakaderera mafuta yogati", viscosity yakawedzera ne20%, whey yekuwedzera mwero yakaderera kusvika 0.1%, uye kugutsikana kwevatengi kwakasvika 92%. Pamusoro pezvo, iyo synergistic mhedzisiro yeSAIB nemapolysaccharides echisikigo senge starch uye pectin inogona kuderedza huwandu hwese hwehupfu ne30% -50% uye kuderedza zvakanyanya mutengo wekugadzira.

Matatu maindasitiri maitiro: SAIB inotyaira nzira nhatu dzechikafu hunyanzvi

1. Dzimwe nzira dzechisikigo pasi peiyo Yakachena Label mushandirapamwe

SAIB, iyo yakavakirwa pa sucrose, inoenderana neEU E-Code (E444) uye FDA GRAS certification uye inorondedzerwa se "yakasikwa yakaenzana" yekuwedzera. Zvigadzirwa zvine hukama neSaib zvakaverengera makumi maviri nesere muzana yemusika wepasi rose wakachena label chikafu muna 2024, kubva pa12% muna 2019, ichiva iyo inosarudzirwa imwe nzira yekugadzira emulsifiers senge polysorbate.

?

2. Injini isingaonekwe yekuvandudza chikafu chinoshanda

Mune zvinwiwa zveprobiotic, mafuta-anonyungudika vhitamini-yakasimbiswa mukaka uye zvimwe zvigadzirwa, SAIB inovandudza kugadzikana kweiyo bioactive ingredients kuburikidza nesolubilization. Zvidzidzo zvakaratidza kuti chiyero chekuchengetedza vhitamini D3 emulsion ine 0.3% SAIB mushure mekupisa tembiricha sterilization (121 ℃, 15 maminetsi) yakakwira kusvika 95%, iyo yakakwira zvakanyanya kupfuura iyo yechinyakare gelatin system (65% -70%).

?

3. Green catalysts yekugadzirwa kwakasimba

Iyo synthesis process yeSAIB inogara yakagadziridzwa, uye iyo itsva enzyme catalytic tekinoroji inogona kuwedzera maitiro ekuita ne40% uye kuderedza kushandiswa kwesimba ne25%. Muna 2024, kambani yemakemikari epasi rose yakavaka yekutanga "zero solvent residue" yeSAIB mutsara wekugadzira, ichideredza carbon emission intensity ne60% zvichienzaniswa nemaitiro echinyakare, uye yakapihwa United Nations Industrial Development Organisation (UNIDO) Green Technology Demonstration chirongwa.

Maonero enyanzvi uye tarisiro yeramangwana

Purofesa Li Ming, mutevedzeri wasachigaro weChinese Society of Food Science and Technology, akati, "Kusiyana-siyana kweSAIB kunoita kuti ive 'Swiss Army banga' mumunda wezvokudya zvinowedzera. Mumakore mashanu anotevera, kushandiswa kwayo muzvokudya zvemiti, kudya kwegeriatric uye zvokudya zvakadhindwa zve 3D zvichaunza kukura kunoputika." .

Kufanotaura kweMusika : Zvinoenderana neshumo neGlobal Market Insights, saizi yemusika wepasi rose weSAIB ichapfuura mazana masere nemakumi mashanu emamiriyoni emadhora panosvika 2025 neCAGR ye6.2%, neAsia-Pacific dunhu (kunyanya China neIndia) richiva iro guru rekukura.

Mhedziso

Sucrose isobutyrate acetate (SAIB) iri kutora hunyanzvi hwekuita tekinoroji seyo fulcrum yekukwidziridza mafungu ekusimudzira indasitiri yechikafu. Kubva pakuwedzera hupenyu hwesherufu kusvika pakugonesa magadzirirwo ane hutano, kubva mukuderedza mitengo kusvika pakufambisa budiriro inoenderera, kukosha kweSAIB kwakasiyana kwakawana kubvumirana kweindasitiri. Nekuvandudzwa kwemirau uye zviyero uye kubudirira muhunyanzvi hwekushandisa, iyi "utatu" wezvikafu zvinowedzerwa icharamba ichitungamira indasitiri kune imwe nguva inoshanda uye ine hutano.
