Description

Calcium5Inosinate is the calcium salt of 5'-inosinic acid, a key nucleotide used as a flavor enhancer. This compound is highly valued for its synergistic effect with monosodium glutamate (MSG) and other nucleotides, significantly amplifying umami taste and savory characteristics in processed foods. It is an essential ingredient for food manufacturers seeking to develop rich, authentic flavors while potentially reducing sodium content. The product is supplied as a high-purity material suitable for demanding food and pharmaceutical applications.

Application

• Flavor Enhancer in Processed Foods: Widely used in soups, sauces, broths, snacks, instant noodles, and canned meats to intensify umami and savory notes.
• Synergistic Blends: Combined with Disodium 5'-Guanylate (I+G) and/or Monosodium Glutamate (MSG) to create powerful, cost-effective flavor-enhancing systems.
• Low-Sodium Food Formulations: Employed to maintain robust flavor profiles in products where sodium reduction is a key development goal.
• Seasoning Mixes & Bouillons: A critical component in dry seasoning blends, bouillon cubes, and powder bases for consistent flavor delivery.
• Pharmaceutical & Nutraceutical Intermediates: Serves as a precursor or intermediate in the synthesis of certain pharmaceutical compounds and nucleotide-based supplements.
• Pet Food & Animal Feed Palatability: Used to enhance the taste and aroma of premium pet foods and specialized animal feeds to improve intake.

Quality Control

Our Calcium5Inosinate is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for food-grade applications. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, identification, and impurity profiles. The product can be supplied to meet relevant specifications such as FCC (Food Chemicals Codex) and customer-specific requirements, ensuring reliable quality and supply chain consistency for global B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
