Product Overview

Lotus seeds are the seeds of the lotus plant, roughly 2-3 cm in size, light brown, and hard with a smooth surface. The interior contains pale yellow endosperm and embryo, and the seeds are primarily sourced from China, India, Japan, and Vietnam.

Rich in nutrients, lotus seeds contain protein, fat, carbohydrates, dietary fiber, vitamins, and minerals. Protein is essential for building body tissues and maintaining metabolism, while the fats provide energy and support skin health. Dietary fiber aids in digestion and helps prevent constipation. Additionally, lotus seeds are rich in starch and amino acids.

In Chinese medicine, lotus seeds are valued for their health benefits, such as nourishing the spleen and kidneys, aiding digestion, calming the mind, and alleviating pain. They are often used to address issues like weak digestion, insomnia, anxiety, and kidney deficiencies.

Lotus seeds are also popular in cooking, used in congee, soups, and desserts such as lotus seed cakes and sweet soups, offering a unique flavor and texture.

To preserve the quality and flavor of lotus seeds, store them in a cool, dry place away from sunlight and humidity. Proper storage extends shelf life, ensuring they retain their freshness and effectiveness.

Main Active Components

The primary active components in lotus seeds include protein, fat, carbohydrates, dietary fiber, vitamins, and minerals. Protein supports body tissue and energy needs, while fat contributes to taste and is essential for skin and nervous system health. Carbohydrates are a key energy source, vital for normal metabolism and physical performance. Dietary fiber promotes digestive health and can help prevent constipation.

Lotus seeds are also rich in vitamins like B vitamins and vitamin E. B vitamins aid energy metabolism and support the nervous system, while vitamin E acts as an antioxidant, protecting against free radical damage. Key minerals in lotus seeds include potassium, calcium, magnesium, and zinc, which are important for various physiological functions.

While lotus seeds primarily consist of these nutrients, further research and analysis may reveal other beneficial compounds.

In summary, lotus seeds are rich in protein, fat, carbohydrates, dietary fiber, vitamins, and minerals, all beneficial to human health.

Botanical Source, Distribution, and Growing Environment

Lotus seeds come from the fruit of the lotus, a plant in the Nymphaeaceae family. Lotus plants are commonly found in China, India, Japan, and Vietnam, where they are also widely cultivated.

Lotus is a perennial aquatic plant that grows in lakes, ponds, and marshes. Its rhizomes are anchored in mud, its leaves float on the water, and its flowers rise above the surface. Lotus seeds form at the center of the flower as it matures.

Optimal growth for lotus seeds requires sufficient sunlight and clean water conditions. Sunlight aids photosynthesis, providing energy and nutrients, while water quality greatly affects growth and seed quality.

Cultivating lotus seeds requires patience and care, including timely fertilization, watering, and weeding. Farmers manage the plants based on local climate and growing conditions to ensure healthy growth and yield.

Harvesting, Processing, and Storage

Lotus seeds are harvested when the lotus flower has bloomed and the fruit has matured. Mature lotus seed pods are light brown, hard, and smooth.

After harvest, the hard outer shell of the seed is removed, exposing the kernel. The seeds are then dried, either by air drying or sun drying, to ensure long-term preservation.

For optimal storage, place lotus seeds in a cool, dry area, away from sunlight and heat. Use well-ventilated containers and keep them away from moisture to prevent mold. Proper storage preserves flavor and quality over time.
