Influence of insects on the extrusion process and the product properties of carp feed

To fulfill the potential for Black soldier fly (Hermetia illucens) larvae meal to be used in commercial aquafeed procduction, knowledge is needed about how it influences the production process and the product properties.

To fulfill the potential for Black soldier fly (Hermetia illucens) larvae meal to be used in commercial aquafeed procduction, knowledge is needed about how it influences the production process and the product properties.

Julian M. Foerster, application technician, and extrusion expert at Brabender addressed this topic in a Masters thesis.  Three different carp feed formulations were extruded on a Brabender twin screw extruder. The first conventional formulation contained 15 % of fish meal. The other two formulations had this fish meal fraction substituted by black soldier fly larvae meal at 50 % and 100 %.

In his presentation at Aquafeed Horizons, June 12, 2019, Julian will describe how the substitution changed the production process: the process parameters, extruder drive load, Specific Mechanical Energy (SME), melt temperature and die pressure. Physical propeties, such as starch gelatinization properties of the feed pellets, diameter, bulk density, floatability , durability, break force, and water stability of the pellets will also be described.

Slated to take place once again alongside the feed and grain trade show, Victam International at the Cologne Exhibition Halls, (Koelnmesse), Cologne, Germany, this year’s conference will focus on the latest advances in practical processing technology, ingredients and formulation. Technical presentations will cover extrusion and drying, processing novel ingredients such as insect meals, optimizing lipids, hatchery nutrition and more.
