Watermelon Seed Protein Suppliers - Wholesale & Bulk

Looking for verified watermelon seed protein suppliers? Nutrada connects you with trusted manufacturers who deliver bulk watermelon seed protein for use in food, beverage, and nutrition industries. With its light texture and nutty flavor, watermelon seed protein is gaining traction as a plant-based alternative for both performance and everyday nutrition products.

What is Watermelon Seed Protein?

Watermelon seed protein is made by pressing and defatting watermelon seeds (Citrullus lanatus), followed by milling the remaining seed cake into a concentrated powder. The process yields a protein-rich ingredient that contains essential amino acids along with minerals like magnesium, iron, and zinc.

Unlike many legume-based proteins, watermelon seed protein has a mild, slightly nutty taste and blends smoothly into powders and mixes. It is commonly used in protein shakes, snack bars, bakery products, and plant-based dairy alternatives.

Types, Varieties & Forms of Watermelon Seed Protein

Commercially, watermelon seed protein is offered in the following forms:

• Protein concentrate: Around 55–65% protein content, retaining natural fiber and nutrients.
• Protein isolate: 75–85% protein content, designed for applications needing higher purity and lighter taste.
• Defatted watermelon seed flour: Lower protein concentration, used in bakery and blended products.

These powders are light beige to off-white and are available in different mesh sizes to suit blending and application requirements.

Harvest Season of Watermelon Seeds

Watermelons are generally harvested in summer, though the season varies by region. In the Northern Hemisphere, the main harvest runs from June to September, while in the Southern Hemisphere, it can extend from December to February. Seeds are separated, cleaned, dried, and processed into oil, flour, or protein. With production spread across multiple regions, supply is available year-round through global trade.

Producing Countries

The leading producers of watermelon seeds, and consequently watermelon seed protein, are:

1. China: The largest global producer of watermelons, accounting for nearly 60% of worldwide output.
2. India: A top grower of watermelons with increasing seed processing for oil and protein powders.
3. Turkey and Iran: Both are significant regional producers with established watermelon seed markets.
4. Nigeria: One of Africa’s largest watermelon producers, with rising use of seeds in local food industries.

These regions supply the raw material base that supports protein production for international buyers.

Trends & Industry Insights

Watermelon seed protein is benefitting from emerging trends:

• Niche protein demand: Brands seek unique plant proteins beyond soy and pea.
• Nutritional positioning: Naturally high in micronutrients, making it appealing for functional food categories.
• Plant-based dairy: Increasing trials in yogurts, cheese alternatives, and blended powders.
• Sustainability: Seeds are often a by-product of fruit consumption, turning waste into valuable protein.
