ZLSILW58BF: The Discoloration Buster for Compound Formulation Industry, Proven Zero Discoloration After 30 Days

Created on 06.30

Compound sweeteners, compound condiments, and powdered flavors are the basic raw materials of the modern food industry, but the discoloration reaction between ethyl maltol and iron ions has been an incurable "chronic disease" in the industry. Industry research shows that more than 60% of white powder food enterprises have experienced varying degrees of discoloration complaints, with single return losses reaching up to millions of RMB.

ZLSILW58BF ultra-low iron silicon dioxide launched by Zhongqi Silicon provides the ultimate solution to this industry pain point. To verify the practical application effect of the product, Zhongqi Silicon conducted strict comparative tests in collaboration with three leading domestic compound enterprises:

Test Conditions: Ordinary silicon dioxide (iron content 320ppm) and ZLSILW58BF (iron content 47ppm) were uniformly mixed with compound sweetener containing 0.15% ethyl maltol, and subjected to accelerated aging at 40℃ and 75% humidity for 30 days.

Test Results:

• Ordinary silicon dioxide group: Visible light pink appeared on the 5th day, turned pink on the 15th day, and deep red on the 30th day

• ZLSILW58BF group: Remained pure white after 30 days, with a color difference meter ΔE value <0.5 (undetectable to the human eye)

In addition to compound sweeteners, ZLSILW58BF is widely applicable to all fields with strict color requirements:

• Flavors and fragrances: Especially powdered flavors containing phenolic substances such as vanillin and ethyl vanillin

• Compound condiments: Chicken essence, chicken powder, soup packets, solid seasonings

• High-end health products: Protein powder, probiotic powder, vitamin complex powder

• Infant food: Infant formula milk powder, complementary food nutritional supplements

"We have tried 5 brands of silicon dioxide before, and the longest they could guarantee was 15 days without discoloration," said the Technical Director of a well-known domestic condiment enterprise. "After using ZLSILW58BF, our products have zero discoloration during the shelf life, and customer complaint rates have dropped by more than 90%."
