IQF Frozen Blood Clam Meat

    Sourced from the intertidal mudflats of the Indo-Pacific, our IQF frozen blood clam meat derives from the ark clam Tegillarca granosa-a bivalve unique among commercially harvested shellfish for its iron-based oxygen transport system. Unlike the vast majority of mollusks that rely on copper-containing hemocyanin, T. granosa employs vertebrate-type hemoglobin and myoglobin, resulting in flesh with a distinctive orange-red to deep burgundy color and a naturally rich concentration of heme iron.

    Live clams are harvested from carefully selected estuarine habitats where fine-sediment substrates and abundant microalgae yield meats of optimal flavor and texture. Immediately after harvest, the clams undergo controlled depuration in UV-sterilized seawater to eliminate sand and gut contents. They are then steam-cooked under validated time–temperature parameters that achieve commercial sterility while intentionally preserving the conformational stability of the iron-bearing hemoproteins. This precision cooking ensures both food safety and the retention of the meat's characteristic color and nutritional value.

    The cooked meats are shelled, graded, and passed directly into an Individual Quick Freezing (IQF) tunnel. In IQF processing, each piece travels independently through a cryogenic or mechanical blast, dropping from cooking temperature to below −18°C within minutes. By passing rapidly through the critical ice-crystal formation zone (−1°C to −5°C), the process produces only micro-crystals that leave muscle cell membranes intact. The result is a product that, upon thawing, shows negligible drip loss, retains its inherent succulence, and delivers a firm-elastic texture indistinguishable from fresh-cooked material. Moreover, the IQF format gives commercial kitchens and manufacturers precise portion control-simply pour out the required amount and return the rest to the freezer without compromising quality.

    Nutritionally, this blood clam meat is an exceptional source of bioavailable iron. Its heme iron is absorbed via a dedicated intestinal pathway with markedly higher efficiency than non-heme iron from plant or dairy sources, making it a strategic ingredient for combating iron-deficiency anemia. The meat also supplies a complete amino acid profile, high levels of vitamin B12 (essential for neurological function and red blood cell formation), zinc, selenium, and long-chain omega-3 fatty acids, while remaining low in both total fat and carbohydrates-a combination of leanness and micronutrient density rarely found in a single ingredient.

    Safety and quality are assured through a comprehensive HACCP-based management system with routine monitoring for heavy metals, marine biotoxins, and microbiological hazards. Every lot is tested against strict specifications for Vibrio species, Salmonella, and Listeria monocytogenes. The product is free of added preservatives, artificial colorants, and sulfites. Packed in food-grade polyethylene bags and master cartons, it is maintained at −18°C or below throughout the cold chain, providing a 24-month shelf life with no degradation of sensory or nutritional properties.
