1. Introduction: The Rising Demand for Immune-Boosting Functional Ingredients
The global immune health market has been growing at an unprecedented pace, driven by rising consumer awareness of preventive health, the increasing prevalence of immune-related disorders, and the shift toward natural, plant-based functional ingredients [1]. Functional food and nutraceutical brands are actively seeking bioactive raw materials that combine scientifically proven efficacy with marketable health claims.
Peanut peptides—bioactive short-chain amino acids derived from enzymatically hydrolyzed peanut protein—are emerging as a promising immune-support ingredient. As a full-category peptide manufacturer, a key contributor to China’s peptide industry standards, and a leader in small-molecule peptide patents, we provide advanced manufacturing capabilities, regulatory expertise, and clinically validated formulations to global B2B partners. Our China-leading, internationally advanced peptide production technology ensures that peanut peptides meet the highest quality and functionality standards for immune health applications.

2. What Are Peanut Peptides?
Peanut peptides are produced by enzymatic hydrolysis of peanut protein, resulting in small molecular weight peptides that are more readily absorbed by the human body compared to intact proteins. These peptides typically range between 300–3,000 Da in molecular weight, enabling faster absorption and higher bioavailability [2].
Key characteristics of peanut peptides include:
- High solubility in aqueous systems, making them versatile for beverage and powder formulations.
- Low allergenicity potential when processed with optimized hydrolysis and purification techniques.
- Sustainable sourcing, as peanuts are a renewable plant-based protein source.
Leveraging our multi-enzyme hydrolysis platform and patented peptide extraction processes, we can tailor molecular weight distribution, purity, and sensory profiles to meet the specific requirements of functional food, dietary supplement, and medical nutrition brands.
3. Bioactive Properties of Peanut Peptides
Multiple studies have demonstrated that peanut-derived peptides possess a variety of health-promoting bioactivities:
- Antioxidant Activity – Peanut peptides can scavenge free radicals and reduce oxidative stress, a key factor in immune dysfunction [3].
- Immunomodulatory Effects – Certain peanut peptides enhance lymphocyte proliferation and increase cytokine secretion, supporting a balanced immune response.
- Anti-Inflammatory Properties – These peptides may downregulate pro-inflammatory mediators, such as TNF-α and IL-6.
- Gut Health Benefits – By supporting beneficial microbiota growth and strengthening intestinal barrier integrity, peanut peptides indirectly improve immune function.
As a company holding one of the largest numbers of small-molecule peptide patents in China, we develop peanut peptide formulations backed by functional verification, ensuring they deliver measurable immune health benefits.
4. Mechanisms of Immune Support
The immune-enhancing effects of peanut peptides are achieved through multiple biological pathways:
- Activation of Immune Cells – Enhancing the activity of T-cells, macrophages, and NK cells to improve pathogen defense.
- Stimulation of Antibody Production – Promoting immunoglobulin (IgA, IgG) synthesis to strengthen adaptive immunity.
- Oxidative Stress Reduction – Neutralizing ROS (reactive oxygen species) to protect immune cells from damage.
- Regulation of Inflammatory Pathways – Modulating NF-κB signaling to prevent chronic inflammation.
For B2B customers, understanding these mechanisms provides a strong foundation for creating evidence-based marketing claims and regulatory submissions.

5. Application Potential in Functional Nutrition
Thanks to their functional versatility, peanut peptides can be incorporated into a wide range of immune-support products:
- Functional Foods – Immune-boosting beverages, snack bars, and ready-to-mix powders.
- Dietary Supplements – Capsules, tablets, and granules for targeted immune support.
- Medical Nutrition (FSMP) – Formulas for immunocompromised patients or post-surgery recovery.
- Synergistic Blends – Combining peanut peptides with oyster peptides, soy peptides, or astragalus peptides for multi-functional immune enhancement.

Peanut peptides are short chains of amino acids obtained by enzymatic hydrolysis of peanut protein. Unlike peanut flour or whole protein, these peptides have smaller molecular weights (typically 300–3,000 Da), making them easier for the human body to absorb and utilize. This enhances their bioavailability and functional benefits, especially in immune support applications.
Research shows that peanut peptides exhibit antioxidant, immunomodulatory, and anti-inflammatory activities. They can stimulate immune cells, promote antibody production, reduce oxidative stress, and support gut barrier integrity, collectively enhancing the body’s natural immune defenses.
Due to their high solubility, neutral taste, and plant-based origin, peanut peptides are versatile ingredients compatible with beverages, bars, capsules, powders, and medical nutrition products. They can also be blended with other bioactive peptides for synergistic immune support.
