Appendix 7Requirements for electrodialysis treatment

The purpose is to obtain tartaric stability of the wine with regard to potassium hydrogen tartrate and calcium tartrate (and other calcium salts) by extraction of ions in supersaturation in the wine under the action of an electrical field and using membranes that are either anion-permeable or cation-permeable.

1.MEMBRANE REQUIREMENTSU.K.

1.1.The membranes are to be arranged alternately in a ‘filter-press’ type system or any other appropriate system separating the treatment (wine) and concentration (waste water) compartments.U.K.
1.2.The cation-permeable membranes must be designed to extract cations only, in particular K+, Ca++.U.K.
1.3.The anion-permeable membranes must be designed to extract anions only, in particular tartrate anions.U.K.
1.4.The membranes must not excessively modify the physico-chemical composition and sensory characteristics of the wine. They must meet the following requirements:U.K.

The stability of fresh electrodialysis membranes is to be determined using a simulant reproducing the physico-chemical composition of the wine for investigation of possible migration of certain substances from them.

The experimental method recommended is as follows:

The simulant is a water-alcohol solution buffered to the pH and conductivity of the wine. Its composition is as follows:

  • absolute ethanol: 11 l,

  • potassium hydrogen tartrate: 380 g,

  • potassium chloride: 60 g,

  • concentrated sulphuric acid: 5 ml,

  • distilled water: to make up 100 litres,

This solution is used for closed circuit migration tests on an electrodialysis stack under tension (1 volt/cell), on the basis of 50 l/m2 of anionic and cationic membranes, until 50 % demineralisation of the solution. The effluent circuit is initiated by a 5 g/l potassium chloride solution. Migrating substances are tested for in both the simulant and the effluent.

Organic molecules entering into the membrane composition that are liable to migrate into the treated solution will be determined. A specific determination will be carried out for each of these constituents by an approved laboratory. [F13The content in the simulant of all the determined compounds must be less than 50 μg/l.]

The general rules on controls of materials in contact with foodstuffs must be applied to these membranes.

2.MEMBRANE UTILISATION REQUIREMENTSU.K.

The membrane pair is formulated so that the following conditions are met:

  • the pH reduction of the wine is to be no more than 0,3 pH units,

  • the volatile acidity reduction is to be less than 0,12 g/l (2 meq expressed as acetic acid),

  • treatment must not affect the non-ionic constituents of the wine, in particular polyphenols and polysaccharides,

  • diffusion of small molecules such as ethanol is to be reduced and must not cause a reduction in alcoholic strength of more than 0,1 % vol.,

  • the membranes must be conserved and cleaned by approved methods with substances authorised for use in the preparation of foodstuffs,

  • the membranes are marked so that alternation in the stack can be checked,

  • the equipment is to be run using a command and control mechanism that will take account of the particular instability of each wine so as to eliminate only the supersaturation of potassium hydrogen tartrate and calcium salts,

  • the treatment is to be carried out under the responsibility of an oenologist or qualified technician.

The treatment is to be recorded in the register referred to in Article 112(2) of Regulation (EC) No 479/2008.

The aim of treatment to reduce sugar content ( the treatment ) is to remove sugar from a must by membrane coupling linking microfiltration or ultrafiltration to nanofiltration or reverse osmosis.

Requirements:

(1)

The treatment induces a reduction in volume as a function of the quantity of the sugar content of the sugar solution removed from the initial must.

(2)

The processes must allow the content of must constituents other than the sugars to be preserved.

(3)

The reduction in sugar content of musts excludes the correction of the alcohol content of wines which are derived from them.

(4)

The treatment must not be used in conjunction with one of the enrichment operations provided for in Annex XVa to Regulation (EC) No 1234/2007.

(5)

The treatment is carried out on a volume of must determined as a function of the sugar content reduction objective being sought.

(6)

The objective of the first stage is to render the must suitable for the second stage of concentration and to preserve the macromolecules greater in size than the membrane’s cut-off threshold. This stage may be carried out by ultrafiltration.

(7)

The permeate obtained during the first stage of treatment is then concentrated by nanofiltration or by reverse osmosis.

The original water and the organic acids not retained by nanofiltration in particular may be reintroduced in the treated must.

(8)

The treatment must be carried out under the responsibility of an oenologist or qualified technician.

(9)

The membranes used must comply with the requirements of Regulation (EC) No 1935/2004 and Regulation (EU) No 10/2011 and with the national provisions adopted for the implementation thereof. They must comply with the requirements of the International Oenological Codex published by the OIV.

Appendix 17

Requirements for deacidification by electro-membrane treatment U.K.

Electro-membrane treatment ( the treatment ) is a physical method for ionic must or wine extraction under the action of an electric field using anion-permeable membranes and bipolar membranes. Using anion-permeable membranes and bipolar membranes allows the reduction in titration acidity and actual acidity (increase in pH) to be controlled.
