Marbling through fat injection

Artificial marbling (fat injection) is the most economically attractive form of meat refinement. It transforms lean cuts (e.g. beef topside, neck) into high-priced steaks with „Wagyu character“. The technological challenge is enormous: a Highly viscous fat emulsion into the muscle fiber so precisely and stably that it looks natural and does not run out during cooking.

Maku offers the complete, synchronized process: From the High-shear mixing stable emulsions (HVB) through to ultra-precise Injection technology for perfect, reproducible marbling.

The injection process

Area of application: Beef (upgrade), pork neck Target: Natural marbling look without „fat lakes“

Key challenges for the customer

  1. Unnatural look: Visible injection channels or large accumulations of fat („fat lakes“) in the meat.

  2. Grease leakage („bleeding“): The injected fat simply runs out again during cooking or vacuuming.

  3. Uneven distribution: Marbling only on the edges, the core remains lean.

Special grease injector
  • Needle and distributor systems specially developed for highly viscous grease media.

  • Precise control of pressure and needle speed for deep penetration.

  • Precise control of pressure and needle speed for deep penetration.

Sensory stability
  • The fat remains bound in the product.

  • Provides the desired melting behavior and juiciness when frying (mouthfeel).

Our recommendations for processing

Emulsion preparation

Area of application: Production of the fat brine Target: A stable, pumpable compound of fat, water and protein

Key challenges for the customer

  1. Phase separation: Fat and water separate before injection (physics works against the process).

  2. Clogged needles: Unstable emulsions or lumps block the injector immediately.

  3. Viscosity fluctuations: Different viscosities lead to incorrect injection quantities and uneven appearance.

Constant viscosity management
  • The brine remains stable for hours and retains its flow properties.

  • A prerequisite for trouble-free, uniform injection.

Temperature control
  • Precise control of the brine temperature to keep the fat in the optimum processing state (not too solid, not too liquid).
