Liquid phytase (PHL) for removal of phytate in food and feed to improve nutrient uptake

 

PRODUCT DESCRIPTION

This product is produced by submerged fermentation of Aspergillus niger followed by purification and formulation. It can break down the undigestible phytic acid (phytate) found in grains and oil seeds and thus release absorbable phosphorus, calcium and other nutrients. Phytase, as a new food processing aid, can improve the mineral absorption by human body. The enzyme has been widely used in feed, medicine, environmental engineering and other fields.

 

MECHANISM

Phytase hydrolyzes the phosphate groups in phytic acid into inositol and phosphoric acid. During processing with grain or oil seeds, the phytase helps the release of inorganic phosphorus, which relieves the inhibition of phytic acid on protease, avoiding the formation of chelates with phytic acid, such as starch-protein-phytic acid, metal ions-phytic acid, thus improving raw material utilization and the nutritional value of product.

 

APPLICATIONS

Ø  Processing of cereals and soy products

l  Removal of anti-nutrient factors

l  Better absorption of metal ions

l  Improved nutritional value of the product

l  Better stability of soybean milk during freezing

 

Ø  Flour processing

l  Reduced phytic acid content in products

l  Elimination of phytic acid chelate and improvement in biological value of product

l  Higher content of inorganic salt in flour, which is good for human absorption

 

Ø  Baking

l  Reduced proofing time for bread

l  Improvement of the texture of bread

 

Ø  Feed industry

l  Elimination of anti-nutritional factors.

l  Promote the digestion and absorption of nutrients, increased animal feed intake and feed biological value.

l  Better utilization of phosphorus in feed.

l  Reduced phosphorus excretion and environmental load.

SAFE HANDLING PRECAUTIONS

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.

 

WARNINGS

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
