Wolffia globosa: The Scientific Name for Mankai

3 min read

Often called the world's smallest vegetable, Mankai is a proprietary trade name for a cultivated aquatic plant, derived from its Thai name "Khai nam" or "water egg". The definitive scientific name for Mankai is Wolffia globosa, a free-floating plant belonging to the duckweed family, Lemnaceae.

Quick Summary

Mankai is the proprietary name for a cultivated strain of the aquatic plant Wolffia globosa, the world's smallest leafy green known for its nutritional density.

Key Points

  • Scientific Name: The scientific name for Mankai is Wolffia globosa.

  • Smallest Vegetable: Wolffia globosa is considered the world's smallest flowering plant and leafy vegetable.

  • Nutrient-Dense: It offers a remarkably high protein content with a complete amino acid profile, a rare feature in plant-based sources.

  • Rich in B12: Unlike most plants, Mankai contains naturally bioavailable vitamin B12, important for those on a plant-based diet.

  • Metabolic Benefits: Clinical studies have shown potential benefits for glycemic control, liver health, and heart health.

  • Proprietary Strain: The commercially available product 'Mankai' is a specific, patented strain of Wolffia globosa grown under controlled conditions.

  • Culinary Versatility: With a neutral flavor, Mankai can be easily added to a wide range of recipes, from smoothies to soups.

What is Mankai?

While Mankai is a specific, proprietary strain of a plant developed and patented by Hinoman Ltd., its lineage traces back to the ancient, nutrient-dense species Wolffia globosa. Native to regions of Southeast Asia, this tiny, rootless aquatic plant grows in still or slow-moving freshwater, forming bright green mats on the surface. In parts of Asia, it has been a dietary staple for centuries, cooked into dishes like curries and omelets.

The Naming History of Wolffia globosa

The scientific journey of Wolffia globosa began with William Roxburgh, who in 1832 first named a specimen Lemna globosa. However, botanists den Hartog and van der Plas later moved it to the genus Wolffia in 1970. The name Wolffia honors Johann F. Wolff, an 18th-century German physician and botanist.

A Nutritional Powerhouse

Wolffia globosa may be tiny, but its nutritional profile is immense. In its cultivated form, Mankai, it is specifically optimized for human consumption and packed with a broad spectrum of nutrients.

Key Nutrients Found in Mankai

  • Complete Protein: Unlike many plant-based proteins, Mankai contains all nine essential amino acids, making it a complete protein source comparable to eggs.
  • Bioavailable Iron: It provides a rich and easily absorbed source of iron, crucial for oxygen transport and energy levels.
  • Vitamin B12: A rare and significant find in a plant source, Mankai contains bioavailable vitamin B12, which is vital for nerve function and blood cells.
  • Omega-3 Fatty Acids: The plant has a favorable omega-3 to omega-6 ratio, beneficial for heart and brain health.
  • Polyphenols: Rich in antioxidants, including polyphenols, Mankai helps combat oxidative stress and inflammation.
  • Fiber: The dietary fiber content aids in digestion and helps regulate metabolism.

Health Benefits Supported by Science

Recent clinical research has revealed promising health benefits associated with a Mankai-enriched diet. Studies have investigated its effects on metabolic health, liver fat, and more, showing positive outcomes when incorporated into a balanced diet.

Notable Research Findings

  1. Glycemic Control: A randomized controlled trial published in Diabetes Care found that consuming Mankai can lead to a lower and delayed blood sugar peak after eating carbohydrates, potentially benefiting individuals with or at risk for diabetes.
  2. Liver Health: The study found that a diet including Mankai significantly reduced liver fat in participants, with some experiencing nearly a 40% reduction, benefiting those with non-alcoholic fatty liver disease (NAFLD).
  3. Brain Health: Research suggests that a green Mediterranean diet enriched with Mankai was associated with a slower decline in hippocampal volume in obese adults.

Cultivation vs. Wild-Sourced

There is a notable difference between the commercially cultivated Mankai and wild Wolffia globosa. The patented Mankai is grown hydroponically under strictly controlled, closed environments to optimize its nutritional content and ensure year-round production. This process also ensures safety by preventing contaminants. In contrast, wild-sourced duckweed's nutritional composition can vary greatly depending on its natural growing conditions, and it can accumulate environmental toxins.

Comparison: Mankai (Wolffia globosa) vs. Spinach

To highlight the unique qualities of Mankai, here is a comparison with a well-known leafy green, spinach, based on general nutritional values per 100g (dry weight basis):

Nutrient Mankai (Wolffia globosa) Spinach (Typical)
Protein Up to 45% of dry weight, complete profile Lower protein content, incomplete profile
Vitamin B12 Bioavailable B12 present Vitamin B12 absent
Iron High levels, bioavailable Contains iron, but can be less bioavailable
Complete Amino Acids Yes No
Omega-3s Favorable ratio Contains some, but composition varies

How to Use Mankai in Your Diet

With a neutral, mild flavor, Mankai is a versatile ingredient that can be easily incorporated into many dishes to boost their nutritional value.

Culinary Applications:

  • Smoothies: A simple addition to any smoothie for a protein and nutrient boost.
  • Soups and Stews: Can be stirred into warm dishes, where it holds its nutritional value.
  • Sauces and Dips: Blends seamlessly into sauces, guacamole, or pesto.
  • Baked Goods: Can be mixed into batter for pancakes or muffins for added nutrients.

Conclusion

In summary, the scientific name for Mankai is Wolffia globosa, a tiny but mighty aquatic superfood with immense nutritional potential. From its rich profile of complete protein, vitamin B12, and antioxidants to its scientifically supported benefits for metabolic and cardiovascular health, Mankai stands out as a significant development in sustainable, plant-based nutrition. Whether cultivated or wild-sourced, understanding its botanical identity as Wolffia globosa is key to appreciating this powerful, naturally occurring wonder. For those interested in sustainable food sources, a deeper look into the research is warranted, such as the studies linked in the citations section below.

Frequently Asked Questions

Wolffia globosa is commonly known as Asian watermeal or a type of duckweed. Mankai is a specific proprietary trade name for a cultivated strain.

Mankai is a specific, cultivated strain of Wolffia globosa, one species of duckweed. While they belong to the same family, the patented Mankai is grown under optimized conditions to ensure a consistent, nutrient-dense profile.

Yes, research confirms that Mankai contains a bioactive, bioavailable form of vitamin B12 that can be absorbed by humans. This is a significant finding for a plant-based food.

Studies suggest Mankai consumption can support metabolic health by improving glycemic control, reducing liver fat, and contributing to cardiovascular and brain health.
