- Claim:
1. A wine-making process comprising: a first step of providing “Acacia Verek” raw gum arabic; a second step of providing a wine to be bottled; a step of dissolving said raw gum arabic in water in order to obtain raw gum arabic in solution with a concentration of gum arabic of between 5 and 50%; a step of filtering said raw gum arabic in solution by means of a tangential filter provided with a synthetic membrane with pore size of between 0.5 and 3 μm in order to obtain filtered gum arabic in solution with a concentration of gum arabic of between 5 and 40%, wherein the synthetic membrane equipping said tangential filter comprises a plurality of ceramic discs arranged in succession facing each other and susceptible of being actuated to rotate with respect to the central axis thereof; a step of admixing said filtered gum arabic in solution in said wine to be bottled in order to obtain a wine to be bottled admixed with gum arabic; a step of microfiltering said wine to be bottled admixed with gum arabic.
- Claim:
2. A wine-making process according to claim 1 , wherein in said microfiltration step, said wine to be bottled admixed with gum arabic is filtered by means of a membrane with pore size equal to or greater than 0.45 μm.
- Claim:
3. A wine-making process according to claim 1 , further comprising a step of bottling said wine to be bottled admixed with gum arabic, following said microfiltration step.
- Claim:
4. A process of filtering a gum arabic for wine-making use, which comprises: a step of providing raw gum arabic; a step of dissolving said raw gum arabic in water in order to obtain raw gum arabic in solution with a concentration of gum arabic of between 5 and 50%; a step of filtering said raw gum arabic in solution in order to obtain filtered gum arabic in solution with a concentration of gum arabic of between 5 and 40%; wherein said filtration step is attained by means of a tangential filter provided with a synthetic membrane with pore size of between 0.5 and 3 μm; wherein the synthetic membrane equipping said tangential filter comprises a plurality of ceramic discs arranged in succession facing each other and susceptible of being actuated to rotate with respect to the central axis thereof.
- Claim:
5. A filtration process according to claim 4 , wherein said filtration step is controlled in order to obtain said filtered gum arabic in solution with an NTU value lower than or equal to 10 .
- Claim:
6. A filtration process according to claim 4 , wherein said filtration step is controlled in order to obtain said filtered gum arabic in solution with a filterability index value (IF) lower than or equal to 10 .
- Claim:
7. A filtration process according to claim 4 , further comprising a step of pulverizing said raw gum arabic, before said dissolution step.
- Claim:
8. A filtration process according to claim 4 , wherein said dissolution step comprises the introduction of said raw gum arabic tangentially in a water flow, obtaining said raw gum arabic in solution.
- Claim:
9. A filtration process according to claim 4 , wherein said raw gum arabic is “Acacia Verek” gum arabic.
- Claim:
10. A filtration process according to claim 4 , wherein said raw gum arabic is “Acacia Seyal” gum arabic.
- Claim:
11. A process of filtering a gum arabic for wine-making use, which comprises: a step of providing raw gum arabic; a step of dissolving said raw gum arabic in water in order to obtain raw gum arabic in solution with a concentration of gum arabic of between 5 and 50%; a step of filtering said raw gum arabic in solution in order to obtain filtered gum arabic in solution with a concentration of gum arabic of between 5 and 40%; wherein said filtration step is attained by means of a tangential filter provided with a synthetic membrane with pore size of between 0.5 and 3 μm; wherein said dissolution step comprises the introduction of said raw gum arabic tangentially in a water flow, obtaining said raw gum arabic in solution.
