Hydrolysis of meat and poultry byproducts
Add value to your edible or feed-grade byproducts with an Alfa Laval hydrolysis system. This presents a lucrative alternative to wet or dry rendering your byproducts into a meat and bone meal.
Alfa Laval offers a range of components used in hydrolysis processes, as well as complete processing lines for both enzymatic and thermal hydrolysis.

High-quality protein hydrolysates
Hydrolysis enables you to process edible byproducts from slaughterhouses into edible proteins with high nutritional and economic value. The hydrolysis process – whether enzymatic or thermal hydrolysis – transforms proteins in the raw material into water-soluble peptides with an attractive flavour profile.
Hydrolysed protein is used in a wide range of products:
- Dietary drinks and protein bars, etc.
- Easy-to-digest food for the elderly and children
- Soup and savoury products
- Noodle sachets
- Injection brine
- Weaning and starter diets for livestock
- Growth enhancers for livestock
Production of hydrolyzed proteins
Alfa Laval offers two different hydrolysis systems:
- Hypro Enzymatic
- Hypro Thermal
Hypro Enzymatic is best suited for soft materials, generating a liquid protein solution with high digestibility and attractive flavour. Hypro Thermal is ideal for raw materials containing larger pieces of bone material, transforming it into a flavourful broth.
Hypro Enzymatic
Hypro Enzymatic is a semi-continuous, low-temperature process based on enzymatic hydrolysis of protein. Initially, the raw material is ground into small pieces before being transferred into a hydrolysis tank (digestor) and heated to around 55°C. The enzymes are added, and the warm blend is allowed to react for a period of time. The reaction time depends on the chosen enzyme and the desired properties of the end product.
The actual digestion process is performed in batches, while the remaining steps are continuous. Downstream of the hydrolysis tanks, the blend is heated to deactivate the enzymes. The higher temperature also enhances the efficiency of the subsequent stage, where bone particles are removed in an Alfa Lava paddle refiner, and the fat, solids, and liquid fractions are separated in a decanter.
Removing the fat in the blend prior to the enzyme digestion stage increases the enzyme effect and the yield. Alfa Laval Oil Plus decanters are specially designed for the extraction of oil and fat and are the best choice for this task. The fat fraction is purified in a separator and, if required, vacuum dried.
The liquid broth can be defatted using an Alfa Laval skimmer centrifuge and further purified in ultrafiltration and nanofiltration membranes to manufacture nutritional protein concentrates and isolates. Water is removed from the final liquid using Alfa Laval AlfaVap and AlfaFlash evaporation systems before the product is dried in either a scraped drum dryer or a spray dryer.
Hypro Thermal
Hypro Thermal utilizes pressure cooking to hydrolyse the proteins. Subjecting the bones and connective tissue to a high temperature over an extended period of time in the pressure-cooking vessel hydrolyses the collagen and breaks down the bone and connective tissue structure to a flavourful broth. The steps after the pressure-cooking vessel are similar to those for Hypro Enzymatic.
