Protein from Fast-twitch Skeletal Muscles in Daily Nutrition

Understanding the Difference: The Era of Choosing Your Protein

Human muscles contain two types of fibers with different functions: "slow-twitch" fibers, used for endurance activities such as maintaining posture and breathing, and "fast-twitch" fibers, used for explosive movements such as jumping or sudden bracing.

　　　　　　　　

As we age, both muscle strength and mass generally decrease, but research shows that "fast-twitch" fibers decline more rapidly than "slow-twitch" fibers.

Here, the protein from Alaska pollock, a white-meat fish, becomes significant. Most of the edible portion of Alaska pollock consists of protein from fast-twitch skeletal muscles. Studies have confirmed that Alaska pollock protein has a high utilization rate, equal to or better than egg protein.

　 　　　　　　　

Focus on Advancing Research into Protein from Fast-twitch Skeletal Muscles!

The　Food Safety Research Department of Nissui Corporation began research on Alaska pollock protein (APP) with Ehime University in 2009, establishing the APP Research Group in March 2018. We conduct joint research with 18 universities and research institutions, including Ehime University, The University of Tokyo, and Waseda University.

Since 2020, we have been publishing research findings on Alaska pollock protein and developing products under the "Protein from Fast-twitch Skeletal Muscles" brand. Products containing 4.5g or more of Alaska pollock protein per serving, such as fish cakes and imitation crab meat, carry the Fast-twitch protein mark as part of our product series.

Based on a comprehensive partnership agreement on food and sports concluded with Tomi City in 2020, Nissui supports top athletes' physical conditioning through protein from fast-twitch skeletal muscles and EPA (eicosapentaenoic acid).

In 2021, we provided a "High-Altitude Training Meal Experience" to approximately 2,500 elementary and junior high school students in the city, serving "Fast-twitch protein Yunomaru Athlete Curry." This provided an opportunity for children to develop an interest in sports, learn about athletes' dietary habits for body conditioning, and understand the importance of proper nutrition in building a healthy body.

Since 2021, Nissui Yunomaru Athlete Restaurant menu items using protein from fast-twitch skeletal muscles have been adapted for school lunches and served at all elementary and junior high schools in the city annually.

We will continue to support your healthy dietary lifestyle through research on Alaska pollock protein and product development.
