quality and high yield enzyme strains were selected, and pectinase was the main
enzyme system in solid state fermentation.It
can effectively degrade pectic substance of feed in animal digestive tract, so
as to achieve the following effects: Break plant cell wall and promote the
release of nutrients in cell wall.Reduce
the viscosity of chyme and improve the contact between digestive enzymes and
nutrients.Produce oligogalacturonides and
free galacturonic acid, maintain intestinal health and reduce diarrhea rate.
(2) pH: applicable
pH range : 3.0-6.0, optimum range : 3.5-4.0.
(3) Definition of enzyme activity: Under the condition
of 50 ℃ and pH3.5, 1 g enzyme powder or 1 ml enzyme
solution decomposes pectin to produce 1 mg galacturonic acid as an enzyme
β - glucanase
β - mannanase
α - galactosidase
is produced by advanced solid-state fermentation technology. It contains
pectinesterase, pectin hydrolase and pectin lyase. It has strong pertinence and
high enzymolysis efficiency.It is rich in a
variety of enzyme systems induced by the medium, which can degrade many
antinutritional factors.Good stability -
gastric acid resistance, pepsin resistance, pelleting temperature resistance,
metal ion resistance and good storage performance.
is a complex polymer composed of D-galacturonic acid, which is connected by α -
1,4 glycoside bond and side chain formed by various neutral sugars.Pectin
is widely filled in the intercellular layer and primary wall of plant cell
wall. It is cross-linked with cellulose and hemicellulose, and encapsulates
macromolecular nutrients in plant cell wall, forming a solid nutritional
barrier, hindering the digestion and absorption of nutrients by animals and
reducing the nutritional value of feed.Pectin
is soluble in water and appears colloidal state, which increases the viscosity
of chyme, hinders the interaction between nutrients and digestive enzymes, and
reduces the activity of digestive enzymes.For
example, the content of pectin in cake feed is as high as 3% - 10%. Pectin is
an important antinutritional factor in meal, which can significantly reduce the
digestibility of feed.It can rapidly
decompose pectin in animal digestive tract to produce galacturonic acid and
free galacturonic acid.When the pectin
molecular structure was broken, the viscosity of chyme decreased rapidly, and
the nutrients wrapped in plant cell wall were fully released.
the viscosity of chyme, improve the digestion and absorption of nutrients, and
reduce the phenomenon of mucus.
products of pectin decomposition (oligogalacturonic acid and free galacturonic
acid) have good effects on maintaining intestinal health and reducing diarrhea
plant cell wall, promote the release of nutrients in plant cell wall, and
improve the digestibility.
