Freshtrusion®
Revolutionising Pet Food Nutrition

Freshtrusion® is a unique process developed to create the world’s finest pet food by incorporating freshly prepared meat and fish ingredients into kibbles. This technology ensures pets receive delicious, highly nutritious diets, maintaining the integrity and digestibility of proteins.

Raw Materials

The Freshtrusion® process begins with sourcing high-quality fresh, chilled meat and fish. These raw materials are transported in refrigerated lorries to maintain their freshness until they reach the manufacturing site.

THE MEAT KITCHEN

Gentle Cooking to Protect Proteins

The gentle cooking process in the Meat Kitchen is crucial for protecting the proteins in the freshly prepared meats and fish. Research demonstrates that thermal processing (cooking) can alter the digestibility and bioavailability of proteins in meat. Cooking at lower temperatures induces structural changes in meat proteins, enhancing digestibility, while high-temperature cooking can cause protein oxidation and aggregation, reducing digestibility.

Impact of Cooking Temperatures
on Protein Digestibility

Low-Temperature Cooking

Cooking at lower temperatures (e.g., 70ºC for 30 minutes) unfolds meat proteins, exposing more cleavage sites for digestive enzymes, improving protein digestibility. Studies on pork muscle showed significantly lower protein oxidation at 70ºC compared to 100ºC and 140ºC.

High-Temperature Cooking

High-temperature cooking (e.g., 100ºC or above) increases protein oxidation and aggregation, making proteins harder to digest. Experiments demonstrated significant decreases in protein digestibility with increased cooking temperatures and durations. For instance, beef muscle cooked at 100ºC for 45 minutes showed substantial protein oxidation and decreased pepsin digestibility, similar to the effects of rapid, high-temperature cooking (1 minute at 270ºC).

Optimal Cooking Conditions

Cooking meat at 75ºC for 30 minutes resulted in better digestibility compared to higher temperatures. Freshtrusion® employs cooking temperatures below 70ºC, with a short pasteurisation step at 82ºC to protect proteins from extensive oxidation and aggregation.

Highly Nutritious Kibbles

After cooking, the freshly prepared meat and fish are combined with dry ingredients and extruded to create dry dog and cat foods. Studies have shown that dry dog foods made with fresh meat or fish as the only animal protein source result in very high protein digestibility values. For example, diets made with beef, pork, chicken, salmon, or pollock showed average protein digestibility values ranging from 88.9% to 90.5%.

Comparative studies also found that fresh poultry diets had significantly higher ileal protein digestibility than those made with rendered meat meal. Freshtrusion® kibbles demonstrated superior digestibility, with a GA diet containing 55% freshly prepared poultry and fish ingredients plus 23% chicken meal achieving an in vitro pepsin digestibility of 91% and an in vivo protein digestibility of 80.3% in dogs.

Benefits of Freshtrusion®

Collectively, the studies indicate that low-temperature cooking conditions protect proteins from severe oxidation and aggregation, enhancing their digestibility. Incorporating high-quality meat and fish ingredients into dry pet foods results in diets with exceptional digestibility and nutritional value for pets.
