Pularin:
Foot ball shaped 60 atoms of carbon at edges is layed in pularin.Pularin atoms are arranged in ball.
Each atom is called Bucky balls and tubes are called Bucky tubes or Nano tubes.Each nano tube is 1 to 7 nm diameter i.e 1nm=50000 part of a hair sting.

Excellent preservative properitesproperites Sorbic Acid Potassium Sorbate can restrain effectively the activity of mould yeast and aerophile bateria Restrain growth and reproduction of the pernicious micro organism as pseudomonas staphylococcus salmonella action to restrain growth is more powerful than killing Meanwhile it can not restrain useful microoranganim growth ad Anaerobicbearing barilli acidophil therefore to lengthen food store peroid and remain food original flavor The preservative efficiency of sorbic acid Potassium sorbate is 510 times sodium benzoate
High safety Sorbic Acid Potassium Sorbate is one kind of nonsuturated fatty acid compounds It can be absorbed by human body rapidly then decomposed into CO2 and H2Omoreover no remaining in body ADI 025mgkg based on sorbic acid FAOWHO 1994 LD50 4920 mgkglarge mouse by mouth GRASFDA 1823640 1994 Its toxicity only 112 times table salts and 140 times sodium benzoate
Good stability Sorbic Acid Potassium Sorbate is stable in sealed staus will not be decomposed until 270C It will be oxidized into colored ones and absorbing moisture in case exposed in air for a long time
Wide application At the momentSorbic Acid Potassium Sorbate has been used extensively in food drinkvegetables in soy tabacco drugs cosmetics agricultural products forage and other domain Its applicaion should be wide and wide in the world
As acidic preservative Sorbic Acid Potassium Sorbate is also used well in neutral foodph6065 The preservative efficiency of sodium benzoate will decrease clearly and have a bed taste while ph4
