YOJOzym-XY150PAP

-- Xylanase for Paper Making

YOJOzym-XY150PAP is a type of xylanase enzyme made from Trichoderma reesei through deep fermentation and extraction technique. Xylan is the second most abundant polysaccharide and a major component of plant cell wall and plant structure tissue. As one of the important part of hemicellulose, xylan is always combined with cellulose, xylogen and the others existing in the plant. Cereal xylans contain large quantities of L-arabinose and are therefore often referred to as arabinoxylans. Xylanase degrades β-1,4-xylosidase from xylan molecule and hydrolysate it into xylo-oligosaccharides and xylose. So it is widely applied in industries of beer brewing, distillery, animal feed, paper and pulp and etc.
EINECS No.: 232-800-2
CAS No.: 9025-57-4
MF: C6H10O5
Grade: Industrial grade for paper making.
HS: 35079090.

PROCESSING CONDITION:
Pulp condition: Before mixed with Xylanase, the pulp temperature should be 45-55°C, PH 6.5-9.5, viscosity 6-10%. Contact period of enzyme and pulp: 1 hour.
The product of Alkaline Xylanase has high standard of stability ranging at pH 5.5-10.5 and temperature ranging from 40°C to 70°C, but almost every mill has unique conditions of fibre furnish, pulping technology and bleach sequence, so the optimal dosage can also depend on the temperature, pH and consistency of the pulp.

UNIT DEFINITION:
One unit of xylanase is defined as the amount of enzyme needed to release 1umol reducing sugar from 5mg/mL xylan solution in 1 minute at pH8.0 and 50°C.

APPLICATION FIELD & EFFICACY:
Used in paper making.
--Improve the pulp bleach ability (added to pulp after cooking or oxygen delignification and prior to bleaching). It can reduce 15-60% bleach usage;
--Improve speed of pulp filtration by 5-10% per hour and improve pulp yielding, thus reduce the production cost and increase the production efficiency;
--Whiten the paper with the same amount of bleach by degrading xylan without cellulase;
--Strengthen the fiber and keep the pulp fiber in good quality;
--Lower COD and BOD of the waste water and decrease time and cost of waste water treatment.

FUNCTIONS:
In paper industry, the interspaces of pulp matrix are always blocked by xylan and xylogen, and thus to cause the lower quality of paper and pulp, reduce the bleaching efficiency, lower paper whiteness, lead to overuse of bleach agents and environmental issues by waste water pollution. This product is developed to effectively degrade xylan in pulp, help separate the pulp cellulose from xylogen, xylan and other impurities, thus to improve the pulp quality and paper whiteness, reducing cost of pulp treatment and waste water treatment.

PACKAGING & DELIVERY:
25kgs/bag or drum; or as per clients' requirements.

STORAGE:
Xylanase is an active biological preparation, should be stored and transported in a cool, dry and ventilated place avoiding sunlight.

EXPIRATION:
Under favorable storage condition, the shelf life is 18 months.
Notice: Tighten the lid after each usage to avoid pollution or damp.

SAFETY:
Enzyme preparations belong to protein, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
