Vital Proteins Collagen Peptides Ingredients Purity Specifications and Manufacturing Sourcing Guide

Core Molecular Specs & Technical Index

Vital proteins collagen peptides ingredients are defined by their precise molecular weight distribution, high solubility, and strict purity thresholds. These ingredients are sourced from bovine hide or fish skin, processed to yield a peptide profile with an average molecular weight between 2000 and 5000 Daltons. This range ensures optimal bioavailability for cosmetic and laboratory applications. The product typically exhibits a protein content of ≥95% on a dry weight basis, with a nitrogen factor of 5.55. Ash content is maintained below 1.5%, and heavy metals such as lead, arsenic, and mercury are controlled to less than 1 ppm each. The material is a free-flowing, off-white powder with a neutral odor and taste, making it suitable for incorporation into various formulations without altering sensory profiles.

Basic Properties and Purity Standards

The purity of vital proteins collagen peptides ingredients is validated through multiple analytical methods. High-performance liquid chromatography (HPLC) confirms the peptide chain length distribution, while amino acid analysis verifies the presence of glycine, proline, and hydroxyproline at consistent ratios. Solubility tests demonstrate complete dissolution in cold water (≤10°C) within 30 seconds, forming a clear solution with no turbidity. The pH of a 1% solution ranges from 5.5 to 7.0, ensuring compatibility with most cosmetic and lab buffers. Storage stability is confirmed under accelerated conditions (40°C/75% RH for 6 months) with no significant degradation in peptide content or functional properties.

Manufacturing & Quality Control

The manufacturing process for vital proteins collagen peptides ingredients begins with the selection of raw materials from certified, traceable sources. Bovine hide is sourced from grass-fed, hormone-free cattle, while fish skin is obtained from wild-caught, non-GMO species. The raw materials undergo rigorous inspection for physical contaminants and microbial load before processing. The production involves enzymatic hydrolysis using food-grade proteases under controlled pH (6.5-7.5) and temperature (45-55°C) conditions. This step is followed by inactivation of enzymes via thermal treatment, then filtration through activated carbon and 0.2-micron membranes to remove impurities and achieve the desired clarity.

Purification and Third-Party Testing

After hydrolysis, the peptide solution is concentrated using vacuum evaporation and then spray-dried to produce a fine powder. The purification process includes ion-exchange chromatography to remove salts and low-molecular-weight fragments, ensuring a consistent peptide profile. Each batch is subjected to third-party testing by accredited laboratories (ISO 17025 certified) for identity, purity, and potency. Certificates of analysis (COA) are provided with every shipment, detailing all specifications including amino acid profile, molecular weight distribution, heavy metals, and microbiological counts. Additionally, stability studies are conducted to confirm shelf life of 24 months under standard storage conditions (15-25°C, dry environment).

Certification List

• ISO 9001:2015 for quality management systems in manufacturing and supply chain.
• Halal Certification from recognized Islamic authorities for bovine-derived products.
• Kosher Certification for compliance with dietary laws, applicable to both bovine and fish sources.
• Non-GMO Project Verified ensuring raw materials are free from genetically modified organisms.
• GMP Compliance with current Good Manufacturing Practices for dietary supplements and cosmetic ingredients.

Bulk Purchase Selection Guide

When sourcing vital proteins collagen peptides ingredients in bulk, B2B buyers must navigate common pitfalls to ensure product quality and supply chain reliability. One frequent mistake is prioritizing price over purity, leading to the acquisition of low-grade peptides with inconsistent molecular weight profiles. Such products may cause formulation failures, such as precipitation or gelation, and can compromise end-product efficacy.
