CONCENTRATED PREPARATION OF PURIFIED PECTOLYTIC ENZYMES WITH VERY LOW CINNAMYL ESTERASE ACTIVITY.

Enzymes particularly recommended for the clarification of white and rosé musts prior to fermentation.

PECTOLYTIC ACTIVITY: 5000 FDU 20/g.

 1 - ORIGIN:

Selected by SARCO laboratory - Bordeaux - France.

 2 - CHARACTERISTICS:

 Ä Its very low cinnamyl esterase activity allows obtaining white wines with a low content of vinyl-phenols thus, with more finesse and cleanliness of aroma.

Vinyl-4-phenol contents according to yeast strain and

 clarification mode on Sauvignon wine

Pexp:        LAFAZYM CL

C1:            Commercial preparation N°1

C2:            Commercial preparation N°2

 Ä LAFAZYM CL is specific of white and rosé musts clarification due to its very low cinnamyl esterase activity but can also be used on red wines with the same results as Lafase 60.

          Ä LAFAZYM CL also provides:

              � A quicker and better clarification due to the degradation of the soluble      pectins extracted during mechanical treatment of the grapes (fall in            viscosity),

              ? Improvement of fining and filtration,

              ? Improvement, during pre-fermentation treatments, of the efficiency of         cooling and centrifugation.

 3 - DIRECTION FOR USE:

Clarification of white and rosé musts:

LAFAZYM CL speeds up the clarification of the must, decreases the volume of lees and allows a better control of the physical treatments as well as the use of selected yeasts.

4 - PREPARATION:

Mix LAFAZYM CL with 10 times its weight in water at ambient temperature

(+/- 20°C).

Leave it for a few minutes then use the preparation within hours.

REMARKS:

� The activity of LAFAZYM CL is decreased by temperatures below 12°C. Nevertheless LAFAZYM CL can work as low as 5°C.

? In case of low pH, it can be advisable to double the usual quantities.

? Products containing Bentonite must be added only once the enzymes work is        considered completed (check with alcohol test).

 The activity of LAFAZYM CL is not altered up to 14% alcohol.

? LAFAZYM CL is not sensitive to the dose of SO₂ commonly used on must and wine, nevertheless any contact with SO₂ solution must be avoided.
