Seplite® Liquor-Specific Resin Removing Impurities and Enhancing Fragrance

Liquor, with its millennia-long history of production and deep cultural roots in China, is valued for its aromatic, pure, rich, smooth, sweet, and clear qualities, earning it broad acclaim. However, conventional liquor manufacturing faces significant challenges.

Challenges in Conventional Liquor Manufacturing: Turbidity and Flavor Impurities:
Flavor Impurities:
During liquor creation via solid-state fermentation, the resulting tail liquor often carries off-flavors from pit mud, accompanied by a minor yellow tint. These undesirable flavors, if not removed, can substantially degrade the liquor's quality after distillation and blending, leading to less enjoyable consumption. Such off-flavors mask liquor 's inherently rich and smooth profile, hindering consumers from appreciating its distinct taste and quality, thus adversely affecting liquor 's flavor and essence.
Turbidity Issues:
Moreover, turbidity issues stemming from sediment accumulation during production pose additional storage challenges. The presence of turbidity in liquor is a widespread concern among distilleries, markedly diminishing liquor's sensory appeal and, in extreme cases, posing risks to human health. The key strategy for quality enhancement involves the elimination of these impurities and the amplification of the liquor's aroma.
Solution for Liquor Downstream Purification Process:
The purification adsorption resin tailored for liquor is based on polymeric resins, featuring a unique pore structure enhanced by the addition of functional groups. 
Through extensive experimentation and refinement, a food-grade, specialized macroporous adsorption resin was created. This resin stands out for its effective removal of impurities, easy regeneration, reusability, and its negligible effect on the desirable flavor compounds in many liquor varieties. Thanks to the adsorption resin's high selectivity, a suitable variant can be selected as necessary to markedly enhance the taste and aroma of liquor. It excels in stripping away unpleasant flavors, rendering liquor cleaner and more invigorating.

Implementation of Liquor Purification Techniques:
  • Elimination of Unpleasant Flavors: 
          Utilizing Sunresin’s adsorption resin for liquor, undesired flavors from solid-state fermented liquor are effectively removed via a straightforward, single-step forward column technique.            This process significantly refines the flavor of the liquor, elevating the overall drinking experience.
  • Clarity Enhancement: 
          Employing an adsorption separation resin to eradicate turbidity boosts the liquor's shelf-life by clearing away sediment, resulting in a clearer liquor.
Benefits and Features of Sunresin's Custom Liquor Purification Adsorption Resin:
  • In comparison with conventional adsorbents like activated carbon and diatomaceous earth, Sunresin's specialized resin for liquor purification exhibits superior selective adsorption capabilities. It efficiently filters out contaminants while preserving the beneficial flavor components of liquor, thus achieving a balance between purification and aroma enhancement.
  • The resin demonstrates a notable effectiveness in treatment, offers ease of regeneration, and is capable of multiple reuses.
  • As a food-grade material, the resin guarantees safety in its application.
A distillery's experiment on removing off-flavors from low-quality distilled spirits:
In the production of liquor at a certain distillery, various low-quality spirits are produced, commonly referred to within the industry as "yellow water spirits." This portion of spirits, due to contact with pit mud and subsequent distillation, contains off-flavors that make it difficult to sell. It is necessary to remove these off-flavors from the spirits.
The need to remove off-flavors from "yellow water spirits" is common in most domestic distilleries. Although "yellow water spirits" cannot be sold normally, they hold certain economic value. Direct blending for sale would affect the quality of the finished liquor, leading to lower liquor prices and affecting the overall profits of the distillery.
After experimental tastings by the customer, it was preliminarily determined that using Sunresin's customized resin specifically for liquor yielded good results, meeting the sales requirements.
Proven Results in Distilleries:
In the liquor production process at a customer’s distillery, a segment of low-quality spirits known within the industry as "yellow water spirits" is generated. These spirits, having been in contact with pit mud and subjected to distillation, acquire undesirable flavors that hinder their marketability. Eliminating these flavors is crucial.
The challenge of removing undesirable flavors from "yellow water spirits" is widespread among domestic distilleries. While "yellow water spirits" are not typically marketable in their original state, they possess some economic value. Attempting to sell them directly by blending could compromise the quality of the final liquor product, leading to reduced prices and negatively impacting the distillery's profits.
Following customer taste-tests, it was initially found that the use of Sunresin's tailor-made resin for liquor showed very good results, fulfilling the requirements for sale.
