   I-asidi ye-Gallic yindawo ephakathi kweyeza kunye ne-antioxidant yokutya, izimonyo kunye nokutya.Ingasetyenziswa njengento ekrwada kwi-resin ye-ionizing semiconductor.Imveliso yayo ye-decarboxylation, i-pyrogallic acid, yi-agent yefilimu yokuchasana nefilimu, i-thermal sensitizer yokufota nge-infrared, kunye ne-benzene.I-polymerization inhibitors ye-ethylene kunye ne-polystyrene, njl., Zisetyenziswa ngokubanzi kumayeza, ukuprintwa kwe-textile kunye nokudaya, unyango lwemigodi, iikhemikhali, oomatshini, ukhuselo lwelizwe, imboni yokukhanya, iplastiki kunye ne-electronics, ukutya, ezolimo kunye namanye amashishini.Iasidi yeGallic kunye noluhlu lwayo lwebhayoloji ziikhemikhali ezilungileyo ezibizayo.Iimveliso zayo zibandakanyai-asidi yegallic yezoshishino, ukucoceka okuphezulu kwe-gallic acid, grade electronic gallic acid, i-pyrogallic acid, i-methyl gallate, ipropyl gallate, njl.

Ukuveliswa kwe-gallic acid nge-chemical hydrolysis yinkqubo yemveli yokuvelisa.Amanqaku aphambili ale nkqubo ngala: i-hydrolysis engaphelelanga ye-tannins, isivuno esiphantsi sokubuyisela i-gallic acid, umgangatho wemveliso ongazinzanga, ukubola kwezixhobo ezinzulu, kwaye ayikwazi ukusebenzisa izinto ezisezantsi ezifana ne-Chinese gall Beihua, ixabiso lemveliso liphezulu, ukusetyenziswa kwekhabhoni ecushiweyo ukwenza umbala kukhulu, kwaye okona kubaluleke ngakumbi kukuba ulwelo lwenkunkuma ephilayo lunongcoliseko olukhulu lokusingqongileyo;

Ingxaki ephambili kwindlela yokutshisa kukuba ukubunjwa kwe-enzymes ye-biological kunye ne-hydrolysis ye-tannins iqhutyelwa kwi-reactor efanayo.Iimeko zinzima ukufikelela kwimeko efanelekileyo, kubangele umjikelezo omude wokuphendula (ngaphezu kweentsuku ezi-3), i-hydrolysis engaphelelanga ye-tannins, kunye ne-tannins eseleyo ye-15% -20%.Ngokujolise kwiintsilelo zendlela yokuvundisa, uphando kwiinkqubo ezintsha ze-enzymatic ziye zaphuhliswa kwihlabathi jikelele.

Ukuguqulwa kwe-enzymatic ye-gallic tannic acid ukuvelisa i-gallic acid ineempawu zezigaba ezibini zokulungiswa kwe-biocatalyst kunye ne-biotransformation reaction.Xa kuthelekiswa nendlela yekhemikhali ye-hydrolysis, eyona nto iphawulekayo yendlela ye-enzymatic kukuba i-biohydrolysis igqityiwe, kwaye i-glucose yemveliso ye-hydrolyzed ingasetyenziselwa njengomthombo wamandla kunye nekhabhoni ukuze i-metabolize i-biocatalyst, engaphuculi nje ukusetyenziswa kakuhle kwemithombo. , kodwa kunye nolwelo lwenkunkuma yokuvubela kulula ukuyiphatha.Ikhuthaza ukhuseleko lokusingqongileyo kushishino.Indlela yeekhemikhali kunye nendlela yebhayoloji ineempawu zazo.Ngokusetyenziswa kwemithombo ye-bio-renewable, uphando malunga nokulungiswa kwe-gallic acid ngendlela ye-biological yenze uphando malunga nokulungiswa kwe-gallic acid nge-gall enzulu.
