Application
When applied to instant noodles, it can shorten water resetting time and avoid stickiness and mushiness of the noodles
When applied to crackers or cakes, it may shorten fermentation time, lower the breakage, make the porous space in good order and therefore lengthen the shelf life.
FAQ
1: What is SAPP? What are its aliases and codes?
In Chinese, it is called pyrophosphate dihydrogen disodium / acid disodium pyrophosphate. Its molecular formula is Na₂H₂P₂O₇, with CAS number 7758-16-9, INS/E 450(i), CNS 15.008 (World Health Organization). Aliases: Disodium pyrophosphate, Disodium dihydrogen pyrophosphate.
2:What is the difference between SAPP and other leavening agents (such as SALP)?
SAPP is slow-acting and produces gentle and uniform gas, suitable for baking / cookies; SALP is fast-acting and produces gas quickly, suitable for fried food products. SAPP is more suitable for products that require stable structure and extended shelf life.
3:Common specifications (such as SAPP 28/40)?
Based on the gas production rate: SAPP 28 (medium speed, 35–43% gas production), SAPP 40 (fast, suitable for high-temperature quick baking), both are food-grade, with purity ≥ 95%.
4: Which kind of payment terms do you accept?
Payment terms can be T/T;LC;CAD;OA;DP and DA.
5.How to place an order?
