Description

Calcium5Guanylate is a high-purity calcium salt of 5'-guanylic acid, a key nucleotide widely recognized for its flavor-enhancing properties. This compound is essential for manufacturers seeking to create or intensify savory, umami tastes in a variety of processed food products. It is a critical ingredient for producers in the food and flavor industries, where consistent quality and reliable supply are paramount for product development and large-scale manufacturing.

Application

• Flavor Enhancer & Umami Agent: Primarily used as a potent flavor enhancer, often in synergy with monosodium glutamate (MSG) and disodium inosinate (I+G) to create a robust umami profile in savory foods.
• Processed Food Production: Incorporated into soups, broths, sauces, gravies, instant noodles, canned meats, and savory snacks to improve overall palatability and mouthfeel.
• Seasoning Blends & Bouillons: A key component in dry seasoning mixes, bouillon cubes, and powder bases for convenient food preparation.
• Pharmaceutical & Nutraceutical Excipients: Used in specific pharmaceutical formulations and dietary supplements where nucleotide salts are required.
• Pet Food & Animal Feed: Applied to enhance the flavor and palatability of premium pet foods and certain specialized animal feed products.
• Research & Biochemical Reagents: Serves as a standard or reagent in biochemical research, food science studies, and analytical method development.

Quality Control

Our Calcium5Guanylate is produced and tested to meet stringent quality standards suitable for food-grade and specialized applications. We ensure compliance with relevant specifications, including Food Chemicals Codex (FCC) guidelines. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and safety parameters, available upon request to guarantee traceability and consistency for your production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect quality and flow properties.
