Product Description

Fructosyltransferase(CAS No.9030-16-4, EC 2.4.1.9)  is a hydrolase with transfer activity and broad receptor activity. Using sucrose as raw material to synthesize oligosaccharides such as sugar cane trisaccharide. Cane oligosaccharide, also known as Fructo oligosaccharide(FOS), is an excellent food ingredient with prebiotic physiology. The fructo oligosaccharide is mainly cane fruit trisaccharide and cane fruit tetrasaccharide.

Fructosyltransferase is derived from Aspergillus Oryzae, produced from submerged fermentation.

Using this product to produce Fructo oligosaccharide, the conversion rate of Fructo oligosaccharide is 56%-62%.

Standard enzyme activity: 5,000 U/g.

Enzyme activity definition: Under the optimal enzymatic reaction conditions (40 ℃, pH 5.0), convert sucrose to oligofructose, and the amount of enzyme required to produce 1 μmol of cane fruit trisaccharide per minute was defined as an enzyme activity unit (U).

Product standard: 

GB1886.174-2016<<National Food Safety Standard-Food Additives-Enzyme Preparations For Food Industry>>

Packaging and Storage

Storage: Store in a cool and dry place(not more than 25℃), avoid exposure to light.

Shelf life: 2 years.

Packaging: 25kg/drum

Application

In the production of oligofructose, the sucrose concentration is 60% (w/v). After the raw material is dissolved, adjust the pH to 5.0～5.5, keep the temperature to 55～60℃, and add fructosyltransferase. The recommended dosage is 0.5 L/t sucrose (dry basis), and the transglycosation time is 16 hours. Finally, we get the following results of content: 0.99% fructose, 28.66% glucose, 12.33% sucrose, 36.35% cane fruit trisaccharide, and 21.68% cane fruit tetrasaccharide.
