Product Description

Product Description

Product Name Polyaspartic Acid Potassium Salt

(Tartrate Stabiliser in Wine)

Identification

Synonyms PASP-K; L-Aspartic acid, homopolymer, potassium salt; Potassium Polyaspartate; KPA
CAS Number 64723-18-8

Introduction

Potassium polyaspartate is the potassium salt of polyaspartic acid, produced from food grade L-aspartic acid and potassium
hydroxide.

Polyaspartic Acid Potassium Salt (Potassium polyaspartate , is proposed for use as a stabiliser against tartrate crystal
precipitation (anti-scaling additive) in wine (red, rosé and white wine), with a maximum use level of 300 mg/L and typical levels in the range of 100-200 mg/L.

Features & Functions
* Strongly effective for tartrate stabilization in red and rose wines: potassium polyaspartate interferes with the formation and growth of potassium bitartrate crystals, thus preventing their precipitation in bottle. It can stabilize highly unstable wines.Rapid and easy-to-use, is a great alternative to physical treatments (cooling, cations exchange resins and electrodialysis) and other stabilizing agents.
* Long-lasting stabilizing effect: It can stabilize wines for a few years.
* Environmentally sustainable: the use of Potassium polyaspartate to stabilize wines for tartrates consumes small amount of water, power and produces little greenhouse gases.
* Respectful of wine quality: no impact on wine sensory profile, less risk of oxidation, preservation of aromatics, color and wine structure.
* Practical, fast and easy: Its application does not require investment in special equipment or specific skilled labor.
