China CFSA Collect Public Consultation Open for 4 New Food Ingredients Including 7 Production Processes of L-Ergothioneine, Silk Fibroin and Glucosyl Hesperidin

from CIRS by

On April 22, 2026, China National Center for Food Safety Risk Assessment (CFSA) issued 4 new food materials. Comments are welcomed before May 22, 2026. Details are as follows:

Glucosyl hesperidin

Name

Glucosyl hesperidin

Basic information

Structural formula:

CAS No.: 161713-86-6
Molecular formula: C₃₄H₄₄O₂₀

Production process

Produced from hesperidin derived from citrus fruits and dextrin as raw materials, through processes including enzymatic catalysis, purification, filtration, concentration, and drying.

Recommended level

≤500 mg/day (calculated based on an α-glucosyl hesperidin content of 75 g/100 g; if the content exceeds this level, it shall be calculated according to the actual content.).

Note

1. Scope of use and maximum dosage:

- dairy and dairy products: modified milk and flavored fermented milk (0.5 g/kg), modified milk powder calculated based on the reconstituted liquid mass, cheese, processed cheese, cheese products, and condensed milk calculated based on the multiplication factor of raw milk.

- beverages: liquid beverages ≤50 mL packaging (5 g/kg), 51–500 mL packaging (0.5 g/kg), and solid beverages calculated based on the reconstituted liquid mass.

- jelly: 10 g/kg.

- cocoa products, chocolate, and chocolate products(including cocoa butter substitute products): 10 g/kg.

- candy: 28 g/kg.

2. Infants, pregnant women, and lactating women should avoid consumption. Labels and instructions must clearly indicate the unsuitable populations and consumption limits.

3. Quality standards and food safety indicators refer to the appendix.
