CALCIUM CHLORIDE POWDER 75g + PURE SODIUM ALGINATE 75g   -

SODIUM ALGINATE E 401
It is  extracted from  seaweed,  and is used  for the spherification process ,
It forms a gel in the presence of calcium ions.
 Add the alginate powder  to flavoured liquid and purées,and use a syringe to squeeze 
droplets into a calcium bath, where they turn into gellified 'caviar'
Switch around the two ingredients for 'reverse spherification' 
Using a sodium alginate bath and a calcium containing purée.

For spherification use 0.2 to 1% of sodium alginate by weight of liquid
Because sodium alginate  starts gelling in the presence of calcium, do not use in a high 
calcium liquid, e.g. milk. 
In case of hard water ( high calcium content), use a calcium sequestrant ( eg.  Sodium
 citrate  or sodium gluconate).

CALCIUM CHLORIDE POWDER E 509:
Made from salt and calcium carbonate ( Solvay process ), no chlorine involved.
This product is sold as a fine white powder , for better dissolution.
It is used extensively in  the different methods of gelification of sodium alginate
It is also added to fresh-cut fruits to keep them firm and extend their shelf life.
Key ingredient in cheese making.

Use this bath for Spherification :
5 to 6.5 Gramms  CALCIUM CHLORIDE POWDER
1L WATER
This calcium setting bath can be kept unrefrigerated indefinitely
