Kompact 120

Powder-free granulated sodium-activated bentonite with remarkable dispersion capacity and colloidal properties
Kompact 120 is a granulated sodium-activated bentonite that offers numerous advantages in the clarification process of musts and wines. Here are some of its main features and benefits:

  • Speed of preparation: Kompact 120 is known for its very rapid dispersion and swelling process, which takes only 120 minutes. This is significantly faster than traditional bentonites, which can take 12 to 24 hours for the same process. This helps reduce the overall processing time in the winery, which can be especially valuable in situations where work organization is critical.
  • Clarification efficiency: Kompact 120 can produce wines and musts with significantly better NTU values than traditional bentonites after only two hours of decanting. This means it offers greater efficiency in removing suspended particles and clarifying the product.
  • Protein reduction: this bentonite is highly effective in protein removal, regardless of specific wine characteristics such as pH, alcohol content or grape variety. It ensures complete deproteinization and protein stabilization.
  • Compact sediments: Kompact 120 promotes the formation of compact sediments, which further facilitates the removal of impurities and improves wine clarification.
  • Respect for organoleptic characteristics: the use of Kompact 120 does not compromise the sensory characteristics of the wine. Wines treated with this bentonite retain their original organoleptic qualities.

Granular sodium bentonite.

10 to 50 g/hl.

Dissolve Kompact 120 in cold water at a ratio of 1:10 until a homogeneous suspension is obtained.
Allow the solution to swell for 2 hours, stirring occasionally until a homogeneous gel forms, and add to the mass to be treated during an indoor reassembly.

1 kg bag, 10 kg bag.
Store in a cool, dry place, away from heat sources.

Kompact 120: the fast and effective solution for wine clarification

Wine clarity is a fundamental condition for the consumer, so intervening with the collage process allows us to achieve four essential objectives:

  • Clarify the wine
  • Improve filterability
  • Improve taste characteristics, such as astringency and bitterness
  • Stabilize the wine to avoid precipitation after bottling.

 

The process of removing unstable molecules is crucial in this process. In a wine, we can find negative and positive charges, and it is on these that the action of clarifiers is based. In our test, we compared our Kompact 120 bentonite with another commercial bentonite. This clarifier has a negative charge, which enables it to remove positively charged proteins, which are responsible for protein casse.

Montmorillonite structure

The process goes like this: the addition of the adjuvant creates aggregation, followed by neutralization of the charge and an increase in the hydrophobicity of the molecule, which results in its precipitation.

In Image 1, you can see the structure of bentonites, mineral colloids consisting of aluminum silicates. When placed in an aqueous medium, bentonite swells and takes on a negative charge.

There are three types of bentonites commercially available: sodic, calcic and activated.

  • Sodic bentonites, despite their high adsorption capacity, tend to form loosely compacted deposits.
  • Calcium bentonites, with lower absorption capacity, generate more compact deposits due to the presence of bivalent calcium ions (Ca++).
  • Activated bentonites, subjected to sodium treatment, are the most popular due to their effectiveness at lower doses and shorter rehydration times.
Fig 2. Initial clarification stage after the addition of the two different additives.

In our study, we focused on two sodium-activated bentonites: our Kompact 120 and another commercial bentonite, identified as “Bento 2” for clarity. We tested both clarifiers on a thermally stressed control wine (80°C for 12-20 minutes), with an NTU value of about 90. Parameters analyzed included deposit volume, deproteinizing action and clarifying efficacy.

Fig 3. Evolution of clarification after 24 hours.

In all parameters evaluated, Kompact 120 proved to be the most effective in removing the proteins responsible for wine opacity. Note that Kompact 120 bentonite takes only 2 hours to disperse and swell, compared to the classic 12-24 hours. The images show a more compact deposit at the end of the treatment, translating into significantly lower losses and higher effectiveness for Kompact 120. This also implies a lower upstream dosage, approximately half. Another relevant aspect is the deproteinizing action, with Kompact 120 capable of removing more than 80 percent of protein in a single day, confirming its efficiency and rapidity in fulfilling its mineral colloidal function.

No Data Found

Finally, to consolidate the collected data, we checked the NTU value (Fig.4). Starting from a wine with a turbidity of 90, we were able to reduce the values to 20 NTU, resulting in a clean and clear wine, minimizing the rejection deposit.
