配方组成:

配制方法:

The soda ash serves to neutralize the small amount of acidic by-products formed during conversion. It is usually correct to assume that for every percent of 35% hydrogen peroxide used, about 0.5% of soda ash will be enough to produce a paste with approximately neutral end reaction (pH 7). Raw starch containing residual processing acid may require higher doses of soda ash.
