【Product Name】 Potassium Polyaspartate(KPA)
【Chemical Formula】 [C4H5NO3K]n
【CAS NO.】 64723-18 -8
【Color】 Light-Yellow or Creamy-Yellow or Light-Brown
【Appearance】 Powder
【Characteristics】
Potassium Polyaspartate(KPA) is polyamide synthesized by the thermal polymerization of L-aspartic acid.
With the structure characteristics of peptide bond and carboxyl group with lots of negative charge, it has powerful functions such as chelate, dispersion, and adsorption, etc.
Its negative charge allows the molecule to bind K+ ions in the wine and thereby inhibit the growth of potassium bitartrate
【Grade】 Pharma/OIV/Food/Cosmetic/Agricultural/Technical
【Application】
KPA has potential excellent performances on inhibiting on potassium bitartrate precipitation in wine making industries. Its effect on tartrate and color stability was compared to that of other additives commonly used in the wine industry.
In addition to strongly inhibiting potassium bitartrate precipitation, it does not affect color stability and can be added close to final filtration without modifying wine filterability.
KPA remains effective in wines even after exposure to temperatures between 30 and 40°C for an extended period, although there was a loss of protection in white wines kept at higher temperatures up to a maximum of 50°C
As a fertilizer synergist,KPA is suitable for urea, compound fertilizer, water-soluble fertilizer, foliar fertilizer, etc. It can promote the absorption of nutrients by various effects
