Sodium metabisulfite solution is often used for color protection. Of course, there are some differences in the process of each factory. For example, in the processing of canned mushrooms, fresh mushrooms are soaked twice in an aqueous solution containing 0.03 g/kg sodium metabisulfite for 1-2 minutes each time.

Prepared as a 20% solution prior to use, added to immature dough in stages during dough preparation. Since the sulfur dioxide released by sodium metabisulfite during dough preparation will reduce the gluten strength of the dough, when the gluten strength and toughness of the flour are large, a small amount of addition can prevent the finished biscuits from being deformed due to excessive gluten strength. Hard dough can be added according to the strength of the flour, but it is generally not used for crisp dough with a high oil-to-sugar ratio. This is because the addition of oil and sugar itself prevents the gluten protein from swelling with water, thereby preventing the formation of large amounts of gluten. No further addition of sodium metabisulfite was required. 聽 Physicochemical properties White or slightly yellow crystal, soluble in water, the aqueous solution is acidic. In addition, it is also soluble in glycerol and slightly soluble in ethanol. It is easily oxidized to sodium sulfate in the air. Moisture easily decomposes, and the melting point is 150 掳 C. It reacts chemically with strong acid and generates sulfur dioxide and corresponding salts.Industrial Phosphate manufacturers website:http://www.food-ingredient.net/industrial-additives/industrial-phosphate/
