IQF Frozen Blood Clam

 

    The IQF Frozen Blood Clam is presented in its complete, natural state with shell intact, but with one critical difference from block‑frozen product: each clam is frozen individually using Individual Quick Freezing (IQF) technology. This means the clams remain loose and free‑flowing – never fused into a solid block. You can take exactly the number you need for a dish, a batch, or an order, and return the rest to the freezer without thawing the entire package. No block breaking, no waste, no compromise.

Scientifically known as Tegillarca granosa, the blood clam is a bivalve mollusc widely cultivated across the coastal regions of China – particularly in Zhejiang, Fujian, Guangdong, and Shandong – as well as in Southeast Asia, where it is a major seafood staple in Malaysia, Thailand, and beyond. The species is named for the vivid red, haemoglobin‑rich fluid found in its soft tissues – a rare trait among bivalves that gives the flesh its characteristic ruby colour and its common name.

    The IQF process locks in the clam's natural moisture, delicate texture, and nutritional value at the moment of freezing. The rapid formation of fine, uniform ice crystals preserves the cellular structure, preventing the moisture loss and texture degradation that can occur with slower freezing methods. The whole round format keeps the shell intact, protecting the meat and its precious haemoglobin‑rich juices during frozen storage – ensuring that when thawed, each clam retains the same plumpness, briny sweetness, and vibrant colour as when it was first harvested.

FAQ

01.What is IQF Frozen Blood Clam, and what species does it refer to?

IQF Frozen Blood Clam is a premium frozen shellfish product made from the species Tegillarca granosa (also known as blood cockle, ark shell, or Akagai in Japanese). This species is one of the four major cultured shellfish in China and is highly valued across East and Southeast Asian cuisines. The product is processed from live blood clams and frozen using Individual Quick Freezing (IQF) technology to lock in freshness. Blood clams are named for the distinctive red liquid in their tissues, which comes from the presence of hemoglobin and myoglobin - a rare trait among mollusks that allows them to survive in low-oxygen muddy environments.

02.How does the IQF freezing process work for blood clams, and what makes it superior to traditional freezing methods?

IQF (Individually Quick Frozen) technology freezes each blood clam individually using high-velocity cold air at extremely low temperatures, typically between -30°C and -40°C. The clams pass rapidly through a cold air tunnel where freezing happens uniformly and quickly. This ultra-fast freezing creates microscopic ice crystals within the shellfish tissue, which cause minimal damage to cell structures. Unlike batch or block freezing, IQF prevents clumping and maintains product individuality, which is critical for processing efficiency and quality. The result is that IQF Frozen Blood Clam retains its natural texture, flavor, and nutritional value far better than traditionally frozen products.

03.What are the main differences between IQF and BQF frozen blood clams, and how do they affect product quality?

The primary difference lies in how the clams are frozen. IQF (Individually Quick Frozen) freezes each clam separately, resulting in free-flowing individual pieces that can be easily portioned. BQF (Block Quick Frozen) freezes clams together in a solid block of ice. The differences in quality are substantial:

Aspect IQF BQF
Ice crystal size Small, minimal cell damage Large, can rupture cells
Texture after thawing Firm, natural Softer, higher drip loss
Portion control Easy – take only what you need Must thaw entire block
Product appearance Individual, premium quality Block format, lower perceived value

For buyers seeking premium quality and operational flexibility, IQF is the preferred choice.
