Bectazyme BBA 1500 commonly  referred to  as beta – amylase.  It is extracted from barley grain by a special treatment.  Manufacturing procedure  Barley Beta-amylase is an exo-amylase that catalyzes the release of successive maltose units by hydrolyzing 1,4,-Alpha D glucosidic linkages from the non reducing end of dextrain chain.

Bectazyme BBA1500 is essentially free from alpha amylase activity and therefore produce maltose with virtually no glucose formation.

Dosage                                : 0.1 to 0.3 kg/ ton ds solids.
Solubility                              : 1% solution is completely misible in water.

Application :

Used for saccharify liquefied starch from maize, potato, wheat etc.          

(1) High maltose syrup containing
Maltose          : 45-60%
D.E.                 : 35 – 50% 
D.P.                 : 0.5 – 2%
DP3                 : 10-25%

Higher Saccharides _ Balance.
Typical dosage is 0.1 to 0.3 litters/ metricton ds starch. Saccharification  time being 4-24 hrs. pH is adjusted to 5.7 .

(2) Very high maltose syrup.
Maltose          : 70% ( 59 – 72%)
Glucose           : 2%  ( less than 2%)
Fermentability: 90% ( 89-92%)

Produced from enzyme liquefied starch in 24-48 hrs by combined use of Bectazyme BBA 1500 and debranching enzyme.  Typical dosage is 0.5 – 1.0litre/ metric ton ds Starch. pH adjusted to 6.0 and temperature is maintained 57’ C.

(3) High conversion syrup of
DE                   : 60-63%
Maltose          : 30-40%
Glucose           : 30-38%

Achieved by enzyme liquefied starch by combined use of BBA 1500 and glucoamylase.  A saccharification time is 12-24 hrs is typical.
