Showcasing VALTYRON® at CPHI & PMEC China 2026

We thank everyone who stopped by Booth E3A53 at CPHI & PMEC China 2026 in Shanghai, where we had an excellent time supporting the exhibition by our partner, Adamanchem. During the exhibition, we introduced VALTYRON®, our premium sardine peptide extract featuring bioactive peptides derived from marine protein hydrolysates. We showcased its established potential as a food ingredient for blood pressure support, as well as its promising potential as an anti-inflammatory cosmetic ingredient. Thank you to everyone who visited Adamanchem booth and showed interest in VALTYRON®. We look forward to continuing our discussions on innovative, marine-derived ingredients for functional food and cosmetic applications.

Sardine Peptide: Potential for Emerging Applications in Emotional Well-being

Protein hydrolysates are increasingly recognized as sources of bioactive peptides with sequence-specific functionality, providing naturally derived alternatives to synthetic compounds. While Sardine Peptide Extract (SPE) is well known for the dipeptide Val-Tyr (VY) associated with cardiovascular support, broader peptide profiling has indicated the presence of additional short-chain dipeptides, such as Tyr-Leu (YL) and Phe-Leu (FL). Recent preclinical studies suggest the potential for these peptides in emotional well-being. Early evidence indicates that YL and FL interact with key neurotransmitter systems, such as the serotonin, dopamine, and GABA pathways, opening new possibilities for SPE as a multifaceted ingredient for systemic health.
