Product Overview

Disodium 5′-Ribonucleotides, commonly known as I+G (E635), is a 1:1 blend of disodium 5′-inosinate and disodium 5′-guanylate. It acts as a powerful umami flavor enhancer with strong synergistic effect when combined with MSG, helps reduce salt content and mask undesirable off-flavors. It is widely used in processed meat, seasonings, instant food, snacks and sauces.

Recommended Dosage

The addition amount depends on food categories, formula requirements and local food regulations.

1.Compound seasonings: 0.1% – 1.0%

2.Meat products: 0.05% – 0.5%

3.Soup & instant food: 0.02% – 0.3% Common blending ratio: MSG : I+G = 10:1 ~ 20:1.

Final dosage should be confirmed according to formulation test and regional food compliance standards.

Key Characteristics

1.Powerful umami enhancer, significantly boosts meaty, brothy and savory notes

2.Strong synergistic effect with MSG, multiplies umami intensity at very low dosage

3.Helps reduce salt content while maintaining desired flavor profile

4.Masks undesirable bitter, metallic and raw off-notes in food formulations

5.Good thermal stability under cooking, steaming and sterilization conditions

6.White to off-white crystalline powder, easy to dissolve and blend

Main Functions

Umami Flavor Enhancer: Intensifies savory, meaty and brothy taste, making food more flavorful and satisfying.

MSG Synergist: Works together with monosodium glutamate to multiply umami effect, reducing total MSG usage.

Salt Reduction Agent: Enables lower sodium formulations without compromising taste.

Off-Note Masker: Suppresses bitter, metallic and raw flavors, resulting in a smoother, more rounded taste.

Flavor Stabilizer: Helps maintain consistent flavor profile during processing and shelf life.

Applications

Processed Meat Products Core application, widely used in ham, sausage, cured meat and ready-to-eat meat products to enhance meaty flavor.

Seasonings & Sauces Applied in chicken bouillon, soy sauce, oyster sauce, hot pot base, soup stock and compound seasonings.

Instant Food Used in instant noodles, instant soup packets and ready-to-eat meal seasonings.

Snacks & Convenience Food Applied in potato chips, puffed snacks, seasoned nuts and popcorn flavoring powders.

Canned Food & Prepared Dishes Used in canned vegetables, ready meals and frozen prepared foods to boost savory taste.

Vegetarian & Plant-based Products Added to plant-based meat substitutes and vegetarian sauces to improve umami profile.
