Storage, Stablity & Handling

Being hygroscopic in nature Soda-Alum requires to be kept in closed bags preferably in closed sheds.

Soda- Alum is non hazardous and non toxic and does not require any special handling techniques.

In closed bags Soda-Alum is quite stable.

Packing

Soda-Alum is available in 25kgs / 50 Kgs polyethylene lined H.D.P.E. bags

Advantages

Soda Alum helps in liberation of Carbon dioxide in two stages. In the dough stage due to presence of water a part of Carbon dioxide is liberated steadily, thus increasing the workability of dough. Balance of Carbon dioxide is liberated at the time of baking, making the baked product uniform and highly porus.

The residual material from Soda Alum, reaction with Sodium Bi Carbonate does not leave any unpalatable taste.

Soda Alum has got highest neutralization value (Bicarbonate equivalent of 104) And yet is cheapest of all the commercially available materials used for this purpose.

Soda Alum can be stored under normal atmospheric conditions
