Iyini i-pectin?I-Pectinukwakheka kwamangqamuzana ezitshalo, atholakala phakathi kwamaseli nasezindongeni zamangqamuzana, futhi ivumela amaseli ukuba abanjwe ndawonye ngokwesakhiwo.Uma sikhuluma ngamakhemikhali, i-pectin iyinhlanganisela eyakhiwe izinsalela ze-galacturonic acid, okuhlanganisa i-proto-pectin, i-pectin ne-pectin ester.I-Pectin ngokuyisisekelo yakhiwe ngama-polymers e-galacturonic acid, aqukethe i-polygalacturonase, i-cellulase, i-hemicellulase, i-asidi amylase namanye ama-enzyme.Ingakwazi ukubola ngokuphumelelayo i-pectin, i-cellulose, i-hemicellulose kanye nesitashi kujusi yesithelo ibe yi-monosaccharides noma i-oligosaccharides, engathuthukisa inani lokudla okunomsoco ngenkathi inciphisa i-viscosity yejusi yezithelo futhi ithuthukisa ukucaca.
Amagilebhisi aqukethe i-pectinase, eguqula i-pectin ibe yi-galacturonic acid kanye ne-methanol njengoba amagilebhisi evuthwa, okwenza isithelo sithambe.
Embonini yewayini, i-pectinase imvamisa ibhekisa ku-pectinesterase, i-polymethylgalacturonase, i-polymethylgalacturonase, i-polygalacturonase, i-polygalacturonase, i-polygalacturonase, ne-polygalacturonase.Ngaphansi kwesenzo esihlangene sawo wonke la ma-enzyme, i-pectin iyashintsha isuka entweni eyi-macromolecular ibe yi-methanol ne-galacturonic acid polymer.
Ngakho-ke, indima ebalulekile yokwelashwa kwe-pectinase yamagilebhisi ukwenza ijusi yamagilebhisi icacise ngokushesha, ikhuthaze ukusebenza kahle kokuhlunga kwejusi yamagilebhisi, ngasikhathi sinye, ngemuva kokucaciswa kahle kwejusi yamagilebhisi kwenziwa ngcono, kunganciphisa isikhathi sokuxhumana phakathi kwejusi yamagilebhisi. kanye nezinto eziqinile, ukuze ugweme ukubonakala kwephunga elingathandeki, njengokunambitha kobumba noma ukunambitheka okuluhlaza.
Uma yengezwa ngesikhathi senqubo ye-maceration ingakwazi ukukhipha umbala kanye ne-tannin kangcono, kanye nezinto ezinuka kamnandi, ithuthukise isivuno sejusi, ngaleyo ndlela ithuthukise ikhwalithi yewayini.
I-1g enzyme powder noma isixazululo se-enzyme esingu-1ml singabola i-pectin ukukhiqiza i-1mg galacturonic acid ngehora ngaphansi kwesimo se-pH3.5 ku-50 ℃.Ukungasebenzi kwama-enzyme ngokuvamile kunqunywa i-substrate (ukugxilwa kwe-substrate, inani le-pH, izinga lokushisa, njll.).Ama-enzyme e-Pectinase azolahlekelwa amandla awo lapho engaphezulu kuka-95℃ imizuzu engu-15.
Ngendlela yokwengeza ye-pectinase, kunezinqubo ezine zokwengeza, okuyizi:
1. Uma yengezwe ku-pulp yamagilebhisi, ingasheshisa isivinini se-maceration, ikhiphe umbala ongcono kanye ne-tannin, izinto ezinuka kamnandi ze-macerate, futhi ithuthukise izinga lokukhishwa kwejusi.
2. Uma wengezwa kujusi wamagilebhisi, inhloso eyinhloko ngalesi sikhathi ukucacisa ngokushesha ijusi lamagilebhisi nokusheshisa ukusebenza kahle kokuhlunga.
3. Uma yengezwe esitsheni sewayini lamagilebhisi kanye nesitsha sokuvutshelwa, ingakhuphula izinga lokucaciswa kanye nokukhipha ijusi ngokusebenza kahle, futhi kunciphise ukungcola kwewayini lokuqala.
4. Faka iwayini elisha, engeza esitsheni sesitoreji kungasheshisa ukuhlukaniswa kwezinto ze-colloidal ewayini, ukuthuthukisa ukucaciswa nokuhlunga umthamo, ukuthuthukisa ikhwalithi yewayini.
Uma udinga i-pectinase, thintana ne-ZBREHON ukuze uthole okuqukethwe okuningiliziwe komkhiqizo!
