Acid Fungal Protease

Description

Deerland AFP is an enzyme preparation derived from Aspergillus niger and contains acid protease which decomposes proteinous substrate to amino acid.

Activity

Protease - 200,000 u/g (Standardized with maltodextrin)

Activity of protease is measured by decomposing activity of milk casein (pH 3.0) based on Folin method (by A reagent). The analysis method is available upon request.

Physical Properties

Form	Fine dry powder
Color	White to light tan
Odor	Free of offensive odor
Solubility	Readily soluble in water

Chemical Properties

Optimum pH	3.0
pH stability	3.0 to 5.0
Optimum Temperature	60C
Thermal stability	Up to 50C

Inactivation

Inactivation can be achieved by raising the temperature to 60C and holding for 30 minutes.

Use Level

Enzyme requirements are generally dictated by processing conditions. They will vary with protein substrate concentration, decree of desired protein hydrolysis, pH, temperature and time of hydrolysis. Initially evaluate Deerland AFP at 0.02 to 0.04 % based on the weight of protein substrate dry matter.

Applications

Pharmaceuticals	Digestive, effectiveness in stomach
Animal feed	Increasing feed efficiencies

Storage Stability

In sealed containers, under cool, dry conditions, the product will maintain the declared activity for at least 12 months. Storage life can be extended by storing under refrigeration at 5C.

Packaging

Deerland AFP is available in 50 kg fiber drums with ring seal and lined with a polyethylene bag.
