Asparagus is a common kind of food with a good taste and high nutritional value. It is used widely in people’s daily meals. Among the main kinds of this food, there are white and green asparagus.
Each of these kinds has its characteristics and advantages to human health. In this article, you will gain knowledge about the overall and detailed information about their general and distinguished features.
After reading this post, you will thoroughly comprehend white and green asparagus. Therefore, you can make your perfect choice in deciding how and when to consume each of them.
The Overall Understanding Of White And Green Asparagus
Asparagus, scientific name Asparagus officinalis, is a kind of plant with a long stem and its tiny leaves grow in a rose-like shape at one end. It is a lily family-classified herbaceous plant of which young shoots are consumed as a kind of spring vegetable.
White asparagus is a special kind of asparagus, which has its own particular attributes. White asparagus is well-known mostly in Europe and Western Asia. It is the result of applying the technique of blanching in cultivation.
The name of white asparagus has already disclosed its most visible feature: the color. It is white outside with a delicate and slightly bitter flavor and is considered “white gold,” “royal vegetable,” or “edible ivory,” thanks to these unique and special features.
Asparagus in general, and white asparagus in particular, provide people with a kind of food rich in vitamin A, vitamin C, iron, calcium, and potassium. Asparagus and broccoli are often compared since they’re both nutritious. This “royal vegetable” is usually served seasonally, from late April to June.
While white asparagus is more popular in Europe, green asparagus is more widely-known in America. It is considered a good source of vitamins for humans.
Green asparagus grows robustly in temperate and cooler climates, especially in long winter. A planted green asparagus may need up to 2 to 3 years to get established and start to produce. However, it is worth waiting as it can be productive for decades.
Green asparagus has low calories, making it valuable for consumption as it is good for health. The taste of green asparagus is a little bit similar to beans but bolder than beans, and it is also nutty and mild.
Differences Between White Asparagus And Green Asparagus
The main differences between the two types of asparagus are their appearance, growing process, and other features, including taste, price, etc. You can see the table below to get an entire view of those differences.
Colors
It is obvious that the main and very first distinguished feature between white and green asparagus is the color. You can notice this at the first look at these two kinds of asparagus.
The difference in the color outside begins inside the asparagus. The reason why green asparagus has this color is that there is chlorophyll inside it. This compound makes asparagus look green.
Inside white asparagus, there is no chlorophyll as it is in green asparagus. Without this pigment, it does not have a green color and remains white even after cooking. Peeled white asparagus looks quite like “scallions” of green onions.
There is another interesting fact about their color. While white asparagus never changes its color even when you cook, green asparagus transfers to white when they have been cooked for a long time.
More About Chlorophyll
Chlorophyll not only creates the difference in white and green asparagus color but also impacts the nutrient elements inside these plants.
Chlorophyll is a substance inside the plants that come into being when the plants expose to sunlight. It is the element that makes the plants look green.
Through a biological process called photosynthesis, chlorophyll helps the plants absorb the energy from sunlight and get their sustenance.
Chlorophyll has many advantages to human health. First and foremost, it is a dominant antioxidant that makes it anti-aging.
Other positive effects of chlorophyll are preventing certain types of cancer, stimulating the immune system’s functions, and providing energy. It also plays a sufficient role in skin protection and acne treatment.
The unique nutritious value of green asparagus compared with white asparagus is the chlorophyll pigment and its benefits.
Surprising benefits from chlorophyll to the human body.
Growing Process
The formation of chlorophyll inside green asparagus and the different colors between the two categories of asparagus result from the distinct growing process of these plants.
White Asparagus – Growing In Darkness
The growth of white asparagus requires darkness. This factor is the root that causes other dissimilarities between it and green asparagus.
White asparagus is grown under the ground and carefully covered. This is to prevent it from being exposed to sunlight. Once it meets sunlight, it will naturally produce chlorophyll and grow to be green asparagus.
The growing of asparagus in the absence of sunlight is called “etiolation.” To conduct this approach, the farmers need to load a thick dirt mold on the asparagus or use black plastic to cover them to avoid sunlight exposure absolutely.
An ideal place to grow white asparagus is a dark environment.
Green Asparagus – Growing Under Sunlight
On the contrary, green asparagus needs sunlight to grow properly. Under sunlight, green asparagus produce chlorophyll, making them look green and get the related nutrients inside the plant. It develops most properly under the direct full sun (from 6 to 8 hours per day).
Harvesting Approach
Being separate in the growth, of course, the harvesting approaches for each of these two kinds of plants are also different.
The difference in harvesting approaches of these two kinds of plants lies in the time. While farmers harvest green asparagus after they grow out of the soil and stay under sunlight, the way to pick white asparagus is different. It must be harvested before rising out of the soil.
White asparagus must not peak out of the soil before harvesting. This ensures that it does not produce chlorophyll and keeps the quality and characteristics of white asparagus.
Taste
Both green and white asparagus have a mild taste. Although they both have the distinct flavor traits of asparagus, there are still slight dissimilarities in their flavor.
White asparagus has a delicately sweet and a little bit bitter flavor. Green asparagus is somewhat grassy and nutty. Green asparagus is also somehow heartier and earthier.
Some people also find white asparagus sweet and vegetal compared to peas and turnips. With its unique taste, white asparagus is usually served with lemon, mayonnaise, mustard, hollandaise sauce, and butter to enhance the dish’s flavor.
Price
In comparison with green asparagus, white asparagus requires more attention and special conditions to grow properly, so its price is higher than green asparagus. Another reason for this higher price is its availability, which is only a few weeks in a year.
Farmers need to concentrate and keep their eyes on the whole growing process of white asparagus to ensure it is not exposed to the sun. This labor-intensive requirement makes the price of white asparagus more costly than green asparagus.
Shelf Life
The storing time of white and green asparagus is the same. The best way to keep asparagus is to refrigerate it. Based on different conditions, the timeframes to store asparagus in the fridge are different.
Different conditions of asparagus include asparagus in different containers and how you have prepared it. They are bare fresh asparagus, asparagus wrapped in a wet paper towel, cooked asparagus, and asparagus in a far with a little water inside.
The table below indicates the period to keep asparagus in the fridge:
Asparagus Condition | Storing time in the fridge |
Fresh Asparagus | 3 – 4 days |
Cooked asparagus | 3 – 5 days |
Asparagus in a jar with a little water inside | 10 – 14 days |
Asparagus covered with a wet paper towel | 5 -7 days |
You can also store asparagus in the freezer with proper preparation. If you want to store your veggies for a long time, feel free to freeze them!
Peeling It Or Not
Peeling is a minor difference between green and white asparagus. In preparing this kind of food, there is a small notice regarding whether you should peel the asparagus or not.
White asparagus has a thick fibrous layer outside and thus requires peeling. You can use a vegetable peeler to eliminate this layer so that it will be tender when you cook.
Green asparagus, on the other hand, is not as thick and tough as the white ones. However, you may need to cut the end and peel the outside thick layer depending on the pencil, regular or large size.
A vegetable peeler is a useful tool for you to peel white asparagus.
Time For Cooking Green Asparagus Vs. White Asparagus
Time for cooking green asparagus and white asparagus is another difference between these two veggies.
Green asparagus is thin, so the time for cooking it is shorter than white asparagus. It requires al dente cooking until becoming tender. White asparagus is thicker and coarser, requiring a longer time to cook. Both of them are great for grilling and toasting.
If you want to try combining white and green asparagus in one dish, you should cook them together only if they have the same relative thickness. Otherwise, you should prepare them separately before putting them together.
