Xylo-oligosaccharide(XOS)are made up of xylose molecules linked by b1-4 bonds and mainly consist of xylobiose,xylothiose and xylo-tetraose. is a type offunctional polymer sugar composed of 2-7 xylose moleculesbonded with β (1-4) glycosidic bondsSoluble in water, with a solubility of 1.15g/mL.
Xylo-oligosaccharide(XOS) with following properties:
Acid and thermal stability: its composition is considerably stable and almost remains the same after placing in acids with PH2.3~8.0 for 20min or under 37 deg for two months.
Low calorie: its caloric value is 4 Kcal approximately in case of xylose,2Kcal in case of xylobiose and xylotriose, and caloric value of xylooligosaccharide with a polymerization degree,xylotetraose is nearly zero Kcal.
Frozen resistance: low freezing point (not freezing under -10) with frost resistance.
Each packing unit must carry a label indicating the name of the product, the net weight, the name of the manufacture, the date of production, the batch code, expiry date or shelf life and storage condition.
Keep in a cool, well-ventilated place, stored away from extreme heat and away from strong oxidizing agents.
Due to the rising cost for international delivery, no free samples, for quality check, the buyer party bear the delivery charges firstly, all the samples charges will refund when the order is secured.
For R&D and small trials, we will charge the minimum cost.
In addition to the quality criteria mentioned above, the material must be conforming to all other requirements of the Chinese Food Regulation that not specifically quoted in this specification.
