Wolffia globosa, commonly known in Thailand as ผำ (Pham), ไข่น้ำ (Khai Nam) or ไข่ผำ, is a tiny edible aquatic plant traditionally consumed in Thailand and other parts of Southeast Asia.Because of its small green appearance, Wolffia is often marketed internationally as “Green Caviar.” Today, dried Wolffia is attracting interest as an ingredient for plant-based foods, functional food concepts, nutrition products, beverages, bakery products, snacks, and other innovative food applications.

What Is Wolffia?

Wolffia is one of the world's smallest flowering plants and grows on the surface of freshwater.

In Thailand, it has traditionally been used as a food ingredient, particularly in local cuisine. The Thai Food and Drug Administration (Thai FDA) identifies Asian watermeal (Wolffia globosa) as an alternative-protein food ingredient.

Why Are Food Businesses Exploring Wolffia?

The opportunity is not simply about adding another “superfood” to a product.

For a food business, the more interesting question is:

What new product, menu, or food concept could you create with Wolffia?

Its combination of Thai origin, distinctive appearance, plant-based nutritional profile, and relatively uncommon ingredient identity gives product developers an opportunity to experiment with something consumers may not have seen before.

Potential applications include:

• Plant-based food products

• New healthy or nutrition-focused menu items

• Superfood and nutrition powders

• Smoothies and functional beverages

• Bakery products

• Snacks and nutrition bars

• Noodles and pasta-style products

• Soups and sauces

• Food mixes and seasoning blends

• New restaurant dishes

• Specialty and premium food products

The actual suitability will depend on the product format, processing method, dosage, taste, texture, and target market.

Thai FDA Highlights Wolffia as an Alternative Protein

The Thai FDA has specifically highlighted ไข่น้ำ / ผำ (Wolffia) as an emerging alternative-protein ingredient within the future-food sector.

In a 2024 Thai FDA publication, the agency reported that Wolffia can contain up to approximately 40% protein on a dry-weight basis, together with calcium, phosphorus, vitamins, essential amino acids, and beta-carotene. The FDA also described Wolffia as an alternative-protein plant and part of the emerging future-food trend.

This figure should not be treated as a guaranteed specification for every Wolffia product. Nutritional composition can vary according to species, cultivation conditions, harvesting, and processing methods.

For commercial product development, buyers should therefore request the supplier's current product specification and Certificate of Analysis (COA).

Dried Wolffia: A Practical Format for Product Development

Fresh Wolffia is a high-moisture ingredient. Drying creates a different format that can be more practical for ingredient storage, transportation, and formulation.

Thailand's FDA's Local to Global platform features a Thai dried Wolffia powder product and describes applications including drinking preparations, desserts, and bakery products.

For food manufacturers and product developers, dried Wolffia can therefore be considered as an ingredient for experimentation and formulation rather than only as a traditional vegetable.

Depending on the supplier's processing method, dried Wolffia may be supplied as whole dried material or in a powdered form.

Before production, buyers should confirm:

• Product form and particle size

• Moisture content

• Protein and nutritional composition

• Microbiological specifications

• Heavy-metal testing

• Pesticide or other applicable residue testing

• Packaging options

• Shelf life

• Minimum order quantity (MOQ)

• Country-specific import requirements

Who Should Consider Dried Wolffia?

Food Factory Owners

If you are looking for a new ingredient that could support a new product line, Wolffia is an ingredient worth testing at the R&D stage.

Purchasing Managers

Restaurant Owners & Chefs

The distinctive identity of Thai Green Caviar may provide inspiration for new dishes, seasonal menus, or specialty food concepts.

An unfamiliar ingredient can create an opportunity for storytelling particularly when it has a recognizable origin, distinctive appearance, and connection to Thai food culture.

Ingredient Distributors & Importers

Dried Wolffia can be evaluated as a differentiated ingredient for customers developing plant-based and innovative food products.

From Ingredient to Product Idea

The biggest opportunity may not be selling Wolffia itself.It may be what a food business can create with it.

Imagine developing:

• Green Caviar Smoothie - A differentiated plant-based beverage concept.

• Wolffia Nutrition Bar - A new ingredient concept for the health and wellness market.

• Wolffia Bakery Products - Explore the powder in bread, crackers, cookies, or other baked products.

• Wolffia Noodles or Pasta - Experiment with Wolffia as part of a new plant-based formulation.

• Green Caviar Menu - Create a distinctive restaurant dish around an ingredient that has a genuine Thai food heritage.

These are product-development ideas, not claims that the current product is already suitable for each application. Commercial suitability should be validated through formulation trials and product testing.
