1.1 Kev txwv ntawm Classical Chemical Synthesis Methods

Cov txheej txheem "ib-kauj ruam" ntawm high-temperature polymerization ntawm qabzib, sorbitol thiab citric acid nyob rau hauv lub tshuab nqus tsev yog paub tab tab sis muaj qhov tsis txaus ntseeg:

Cov tshuaj tiv thaiv kub yuav tsum nruj me ntsis tswj ntawm 130-160 ℃ (± 2 ℃).

Cov khoom lag luam muaj ntau qhov kev faib tawm ntawm polymerization (nrog rau DP tus nqi xws li 2 txog 100).

Tus nqi poob ntawm cov decolorization tom ntej, desalination thiab purification cov kauj ruam mus txog 15%

1.2 Kev tawg hauv cov txheej txheem Enzymatic

Xyoo 2023, "Dual-enzyme Synergistic Catalytic System" tsim los ntawm Jiangnan University tau ua tiav qhov tseem ceeb:

Kev sib xyaw ua ke ntawm immobilized glucosyltransferase (GTase) thiab rubulan tau txais yuav.

Cov tshuaj tiv thaiv yog me me (60 ℃ / atmospheric siab)

Molecular weight controllability txhim kho (Customizable 500-5000Da khoom)

Tshooj 2: Kev Ua Raws Li Txheej Txheem Tsim Kev Txawj Ntse Plaub Ntug

Lub "5G + Industrial Internet" cov kab ntau lawm ntawm Shandong Longda Biotech, uas tau teem sijhawm los ua haujlwm hauv xyoo 2024, ua kom pom qhov ua tau zoo xav tsis thoob:

Raw khoom pretreatment: Ib qho AI pom kev txheeb xyuas qhov system yog siv los tshem tawm cov piam thaj tsis zoo

Cov tshuaj tiv thaiv Polymerization: Microwave-pab catalysis txo lub sij hawm cov tshuaj tiv thaiv rau ib feem peb ntawm cov txheej txheem ib txwm muaj

Purification system: Lub tshuab ua ke ntawm molecular distillation thiab nanofiltration ua tiav 99.2% purity

Kev sib piv ntawm cov tseem ceeb parameter

Cov Lus Qhia: Cov txheej txheem niaj hnub txheej txheem Kev siv hluav taws xob (kWh/kg) 8.73.2 Dej siv (m3/t) 154.5 Tawm (%) 6892

Tshooj 3: Tshiab Paradigms ntawm Green Manufacturing

3.1 Kev siv tus nqi siab ntawm cov khoom lag luam

Extraction ntawm xylooligosaccharides los ntawm polymeric residual kua (tus nqi lag luam 120,000 yuan ib tuj)

Cov kab mob microbial yog tsim los ntawm cov khoom pov tseg los ntawm cov khoom siv hauv lub xeev fermentation

3.2 Carbon Footprint Management

Qhov tseeb LCA kev ntsuam xyuas ntawm Huaxi Biotech qhia:

Cov pa roj carbon emission ib tuj ntawm polydextrose poob los ntawm 2.1tCO?e rau 0.7tCO?e

Ua tiav 30% ntsuab hluav taws xob hloov hauv cov kab ntau lawm los ntawm photovoltaic zog mov

Tshooj Plaub: Tus Qauv Tshiab ntawm Kev Sib Tw Ntiaj Teb Kev Sib Tw thiab Kev Koom Tes

Eu: tsom mus rau kev tshawb fawb synergistic ntawm polydextrose thiab Probiotics (13 daim ntawv thov kev noj qab haus huv ntawm EFSA tau pom zoo)

Nyiv: Tsim cov khoom uas tsis muaj molecular-yuag (800-1500Da) rau cov neeg laus

Tuam Tshoj: Ua hauv cov khoom siv tas mus li (cov khoom siv xa tawm mus rau sab hnub tuaj Asia thiab Middle East)

Tus tuav ntaub ntawv ntawm Tuam Tshoj Bio-Fermentation Industry Association tau tshaj tawm tias: "Lub sijhawm 14th Tsib Xyoo Kev Npaj, lub teb chaws tus qauv 'Kev Ntsuas Kev Ntsuas rau Green PolyGlucose Factories' yuav raug tsim."

Yav tom ntej Outlook

Nrog rau infiltration ntawm hluavtaws biology technology, "biosynthesis txoj kev" ntawm ncaj qha synthesizing polyglucose siv cell factories tau nkag mus rau theem pilot. Txoj haujlwm hloov kho engineering ntawm Tianjin Institute of Industrial Biotechnology, Suav Academy ntawm Kev Tshawb Fawb, qhia tau hais tias txoj kev xav, cov nqi tsim khoom tuaj yeem raug txo mus rau 40% ntawm qib tam sim no.
