Applications
1. As a food additive, it is used for bleaching, preservation and color protection of candies, pastries, preserved fruits, wine, fruits and vegetables, as well as leavening treatment of baked foods.
Food processors frequently encounter troublesome issues such as undesired browning, dull product appearance, short shelf‑life and insufficient fluffy texture for baked goods during production. These defects raise scrap rates and weaken the market appeal of finished food.
As a functional food additive, it delivers multi‑fold performance for your production. It performs bleaching, preservation and color‑protection for candies, pastries, preserved fruits, wine, fruits and vegetables. Meanwhile, it supports leavening treatment to achieve ideal texture for baked foods. It effectively restrains discoloration, extends storage period and optimizes baked texture, helping you lower waste and maintain stable finished‑food quality.
2.Residual chlorine corrosion, poor treatment stability and high chemical consumption are common pain points across multiple industrial processes.
For industrial uses, it applies to textile dechlorination, circulating water dechlorination and deoxygenation, wastewater treatment, chemical reduction, leather softening and rubber coagulation. Boasting excellent performance and high cost‑performance, it stabilizes your processing effect and optimizes chemical‑use expenditure.
