Moringa leaves come from the Moringa tree which is commonly known as the drumstick tree. This tree is native to the Indian subcontinent but now it is grown in tropical and subtropical regions around the world.
Learn about these leaves that are known to have amazing health benefits. This post includes detailed information about this plant that will help you educated yourself about moringa.
Moringa Leaves: Botanical Information
The botanical name of Moringa is Moringa oleifera.
Moringa leaves are small and oval-shaped that typically grow in clusters on the branches of Moringa tree. They are bright green in color when fresh and highly nutritious. They have a slightly bitter and earthy taste which is quite similar to that of spinach and has a hint of a horseradish-like sharpness in the flavor.
Parameters for Categorizing Moringa Leaves
There are different parameters that are used for categorizing moringa leaves in order to conclude their quality and suitability for different uses.
- Color: High-quality moringa leaves are bright green in color. The color is an indication of freshness and high nutritional value. The color of the leaves should be uniform. Yellowing or browning of leaves or discoloration of leaves is an indication of poor handling or ageing.
- Size and Shape: Large sized leaves that are mature indicate high quality. They should be uniformly oval and should not have any deformities. Consistency in size is also an important parameter on which these leaves are categorized.
- Texture: The leaves should be tender but firm. This is an indication of their freshness. In case of moringa powder, fine and smooth texture is considered to be of good quality. The powder should be free from coarse particles or lumps.
- Moisture Content: Fresh moringa leaves should have the right moisture level. They should be neither too dry or too wet as former indicates low nutritional value and latter makes them more prone to molds. The ideal moisture content for these leaves is around 5-7%.
- Purity and Cleanliness: High-quality moringa leaves should not contain any dust, dirt, and foreign matter. They should also be free from chemical residues.
- Nutrient Content: Good quality moringa is supposed to have nutritional profile with vitamin A, vitamin C, calcium, and iron content. It should also contain high amount of protein, including essential amino acids.
- Aroma and Flavor: Fresh moringa leaves are considered of high quality when they have a mild, earthy aroma. Off smell indicates poor handling and spoilage. Premium quality moringa leaves should be slightly bitter and earthy and should not have any off flavors as this is an indication of spoilage.
- Leaf Integrity: Whole and intact leaves are preferred over broken or crushed leaves, especially when moringa is consumed fresh. High quality leaves should be free from any kind of physical damages like tears, bruising etc.
- Drying and Processing Method: Leaves dried under sun or shade are preferred over leaves that are dried using artificial heat as natural drying helps in preserving the nutrients. Also, the method of processing these leaves like drying, washing, grinding also affect the quality of the product, especially in ground form.
Different Grades of Moringa Leaves
We have come up with different grades of moringa leaves that have been created based on the parameters that have been shared above:
- Grade A (Premium Grade): Moringa leaves under this category are bright and vibrant green. They are uniform in size and do not have any deformities. Their texture is tender but firm. The moisture content levels are optimal. They are free from foreign matter and are often organic-certified. These leaves feature mild, earthy aroma and have slightly bitter flavor with no off tastes. They are carefully processed using methods that help in preservation of nutrients. They make a perfect choice for high-end health supplements and teas.
- Grade B (Standard Grade): These leaves are green but are not that vibrant as there may be minor yellowing. They have uniform size but sometimes they may be a mix of medium to large leaves. They texture is firm but with some variability. They have acceptable moisture content. Having small amounts of dust and foreign matter, they are not as pure as Grade A. They have an earthy aroma and flavor but with slight variations. These leaves are processed using standard drying and processing methods. They are commonly used in mid-range health supplements, teas, and food additives.
- Grade C (Economy Grade): The leaves under this category are less vibrant and have noticeable yellowing or browning. They have mixed sizes and also include wilted or slightly damaged leaves. They have higher moisture content and may contain some foreign matter. They have less desirable flavor and aroma. They are processed using basic processing methods which reduce the nutrient content. They are mostly used for low-cost supplement, industrial purposes, and bulk powders.
- Grade D (Low Grade/Rejects): These leaves are predominantly yellow or brown. They are irregular in size and include damaged leaves. These are dry and brittle leaves with inconsistent moisture content. Significant amount of foreign matter is present in these leaves. They have off-putting flavor and aroma. They are poorly processed because of which they have degraded quality. They are not suitable for human consumption and are mostly used for animal feed or compost.
What are the Best Conditions for Growing Moringa Leaves?
Every plant has certain conditions under which they to grow and develop healthy. Here is the list of conducive conditions for growing moringa:
- Climate: Moringa requires tropical and subtropical climates to grow. The ideal temperature range for the plant is between 25°C to 35°C (77°F to 95°F). It also requires full sun for optimal growth. Direct sunlight of at least 6 hours every day is required by the plant. The annual rainfall of around 250-1500mm is important for its growth. It can also thrive in areas with less rainfall provided it is well irrigated.
- Soil: It flourishes in well-drained, sandy or loamy soils. It cannot grow in heavy clay or waterlogged soils. Moringa can grow in soils that lack nutrients but adding organic matter can improve the overall health of the plant and leaf production.
- Watering: For establishing roots, young moringa plant needs regular watering. Once it is established, it is a drought-resistant plant. Regions with low rainfall may require supplemental irrigation during dry periods.
- Planting: Moringa trees need a spacing of 3-5m for healthy leaf production. These trees can be grown from seeds or cuttings. If seeds are used, then they should be sown 2cm deep in soil and if they are planted using cuttings then the cuttings should be 1m long and should be planted 30cm deep in soil.
- Altitude: Although these trees can grow at altitudes up to 2,000 meters above sea level, but they are preferred to be grown on lower elevations because of warmer temperatures.
Harvesting and Processing Moringa Leaves
Harvesting and processing moringa leaves is crucial for the nutritional value and quality of leaves. Shared below is the step-by-step guide to the process:
Harvesting
- Timing of Harvest: The right time for harvesting these leaves is 6 to 8 weeks after planting. These leaves can be harvested regularly throughout the year in warm climates. Ideally, a gap of 35-40 days is maintained between two harvests. Harvesting is done mostly in the morning when the leaves are fresh.
- Method of Harvest: The leaves are harvested by hand. They are either plucked individually or by cutting the entire branch. The moringa trees are regularly pruned for encouraging bushier growth and better yield.
- Washing: Moringa leaves are washed to remove dirt, dust, and other contaminants. For this process, clean and potable water is used and sometimes a mild saline solution is added to the water to ensure removal of the pests.
- Drying: This is an important stage for preventing spoilage and also preserving the nutritional content. The leaves are dried in the shade for preserving the nutritional value and green color. These leaves are spread thinly on trays or drying racks in a well-ventilated place where the temperature is around 30°C to 40°C (86°F to 104°F). In commercial operations, mechanical dryers are used for speeding up the process. These are low-temperature dryers for preserving the nutrients.
- Grinding: Moringa leaves are then ground into fine powder with the help of grinder or mill. This powder is then sifted for removing coarse particles.
- Storage: The powder or leaves are stored in a cool, dark, and dry place in a well-ventilated setup. Proper storage is important to extend the shelf life of the product.
