Longzyme\u00ae \u03b2-Amylase CAS 9000-91-3<\/strong><\/h2>\n

 <\/p>\n

Principe<\/p>\n

La \u03b2-amylase est une exonucl\u00e9ase qui part de l'extr\u00e9mit\u00e9 non r\u00e9ductrice de l'amidon liqu\u00e9fi\u00e9 et l'hydrolyse s\u00e9quentiellement en fonction des unit\u00e9s de maltose, tandis que la r\u00e9action de transposition de Walden se produit, de sorte que le produit est transform\u00e9 de maltose de type \u03b1 en maltose de type B. Elle ne peut pas hydrolyser la liaison a-1,6-glycosidique \u00e0 l'embranchement de l'amidon. Il ne peut pas hydrolyser la liaison glycosidique a-1,6 au niveau de la branche de l'amidon, et la d\u00e9composition de l'amidon s'arr\u00eate \u00e0 2~3 r\u00e9sidus de glucose avant la liaison 1,6, de sorte que le maltose produit est essentiellement d\u00e9pourvu de glucose.<\/p>\n

Caract\u00e9ristiques du produit
\n1\u3001Temp\u00e9rature : stable en dessous de 65\u00b0C, la temp\u00e9rature la plus appropri\u00e9e se situe entre 55\u00b0C et 60\u00b0C.
\n2. Plage de valeurs de pH : plage de pH efficace de 3,0 \u00e0 6,5, plage de valeurs de pH optimale de 5,0 \u00e0 5,6.
\n3\u3001Effets des ions m\u00e9talliques courants sur l'activit\u00e9 enzymatique : une faible concentration de CaMg a un effet activateur, Hg, Fe et les agents oxydants ont un effet inhibiteur sur l'activit\u00e9 enzymatique.<\/p>\n

Propri\u00e9t\u00e9s du produit<\/p>\n

1, Sp\u00e9cification du produit : liquide brun, activit\u00e9 enzymatique 700000u\/mL.
\nEnzyme liquide pH(25\u2103\u2103):4.0-6.0, capacit\u00e9:\u22641.25g\/mL.
\n2\u3001D\u00e9finition de l'activit\u00e9 enzymatique:1mL d'enzyme liquide (ou 19 enzyme en poudre) \u00e0
\nDans les conditions de pH5,5 et 60\u2103, le nombre de mg de maltose form\u00e9s par l'hydrolyse de 1,10% d'amidon par heure est une unit\u00e9 d'activit\u00e9 enzymatique, qui est exprim\u00e9e par u\/mL(u\/g).
\n3\u3001Norme produit : mise en \u0153uvre de notre norme LDZJ03.04-2010.<\/p>\n

M\u00e9thode d'application<\/p>\n

Les meilleures conditions de saccharification d\u00e9pendent du temps de saccharification, du pH, de la temp\u00e9rature, de la concentration en substrat et du dosage enzymatique. Chaque fabricant d'applications doit d\u00e9cider des conditions optimales du processus en fonction de ses propres conditions, et les m\u00e9thodes g\u00e9n\u00e9rales recommand\u00e9es sont les suivantes.
\n1, dans le sirop de maltose (sirop), brassage de la bi\u00e8re, 0,1-0,3L\/t de substrat sec conditions optimales pour le premier 12-30 heures, le second saccharification 0,5-1 heures.
\n2, sirop \u00e0 haute teneur en maltose (>70%) : n\u00e9cessit\u00e9 d'une synergie avec la saccharification de la Pullulanase. Utilisation sugg\u00e9r\u00e9e : B-amylase 0,5-1,0L\/t kilobase, Pullulanase 0,5-1,0L\/t kilobase.
\n0,5-1,0L\/t de base s\u00e8che (l'activit\u00e9 enzymatique compte pour 1k unit\u00e9), saccharification pendant 24 heures.
\n3\u3001Sirop \u00e0 tr\u00e8s haute teneur en maltose (>90%) : n\u00e9cessit\u00e9 d'une synergie avec la pullulanase et l'enzyme maltotriose. Utilisation sugg\u00e9r\u00e9e : \u03b2-amylase 1,5-2,0L\/t de base s\u00e8che, Pullulanase 1,5-2,8L\/t de kilobase (activit\u00e9 enzymatique en 1 000 unit\u00e9s), saccharification pendant 24 heures, ajouter l'enzyme maltotriose 1,5-2,0L\/t de kilobase, et poursuivre la saccharification pendant 24 heures.
\nEmballage et stockage
\nEmball\u00e9 dans un tambour en plastique liquide, 28kg\/tambour. Ce produit est une substance biologiquement active, la lumi\u00e8re forte, la temp\u00e9rature \u00e9lev\u00e9e, l'acide fort, l'alcali fort causeront l'inactivation de l'enzyme, il faut \u00e9viter la lumi\u00e8re directe du soleil et placer le produit dans un endroit sec et \u00e0 basse temp\u00e9rature.<\/p>\n

La \u03b2-amylase est une sorte de pr\u00e9paration enzymatique tr\u00e8s efficace extraite et raffin\u00e9e \u00e0 partir de plantes par une s\u00e9rie de m\u00e9thodes scientifiques. Ce produit poss\u00e8de un syst\u00e8me enzymatique pur, une grande vigueur, une bonne r\u00e9sistance \u00e0 la chaleur et aucune odeur particuli\u00e8re. Il est largement utilis\u00e9 dans la fabrication de la bi\u00e8re, du vinaigre, du sirop \u00e0 haute teneur en maltose, du maltitol cristallis\u00e9 et d'autres sucres dont le produit ou le produit interm\u00e9diaire est le maltose.<\/p>\n

La \u03b2-amylase est utilis\u00e9e dans l'industrie alimentaire comme agent saccharifiant dans la fabrication du sirop de maltose, de la bi\u00e8re, du pain, etc. Une utilisation importante de la \u03b2-amylase dans l'industrie pharmaceutique est la fabrication de maltose, l'absorption du maltose ne d\u00e9pend pas de l'insuline, de sorte que m\u00eame les patients diab\u00e9tiques peuvent \u00e9galement \u00eatre consomm\u00e9s avec mod\u00e9ration. En m\u00e9decine, la \u03b2-amylase peut \u00eatre utilis\u00e9e comme aide digestive avec l'\u03b1-amylase.<\/p>\n
