For a huge number of people, bird nests are not at all associated with a nutritious and tasty lunch. However, Asians and Americans alike have long been aware of the high nutritional value and health benefits of this product. It cannot be attributed to consumer goods, because the cost is quite impressive.
The culture of eating swiftlet nests for food has a long history. The first mentions date back to the 7th century AD. From the very beginning, a rare and very useful product was available only to the imperial families.
Until recently, catching swiftlet nests was laborious and very dangerous because birds in the wild often nest in hard-to-reach places on the slopes of rocks, in caves. However, in the course of the study, the features of their behavior were identified, the imitation of which helped to attract females and males to man-made premises. In them, farmers create suitable microclimate conditions for swifts to comfortably build nests and lay eggs. Thus, farms for the extraction of the swallow's nest appeared. Their number is steadily growing, which makes it possible to increase the annual turnover of this delicacy and gradually reduce the cost.
Classification of edible bird nests of swifts-swifters:
- Bloody … This species is considered the rarest and most expensive. Some believe that this color is due to a lack of saliva in birds and the presence of an admixture of blood. However, this statement is not true. The red tint is due to nutritional characteristics and indicates the presence of more nutrients. Additional enrichment with minerals usually occurs if the bird builds a dwelling to continue offspring in the wild, in particular in mountain caves. The nests are gradually covered with iron and other minerals, which oxidize over time - this is how an interesting shade is obtained. Such nests are collected in Thailand in limestone caves.
- Red … The color can be pinkish brown, pink and orange. Also comes across in the wild. The shade depends on the types and amount of impurities with which the fibers are impregnated.
- White … The most popular and cheapest product, as birds build nests in farm conditions. Such a product is fragrant, fragile and free of impurities. Most often, breeders cut nests before laying eggs, so they are white and clean. Feathers only occasionally come across.
- Gray … The darkened bowls are those in which there were already chicks. They are less valuable, but still go to the entrance. This requires more thorough cleaning.
What the nests are made of, with the help of which the swifts are made, and why they can be eaten are interesting questions. In our area, birds build a dwelling from twigs, leaves, needles. Salanganes use their saliva for this. It is a sticky substance that hardens rather quickly, creating a strong bed. Various seafoods are often used - the finest pieces of algae, fry, molluscs, eggs. Because of this, many attribute the delicacy to seafood.
On average, the wholesale price for 1 kg of white nests is about $ 1200. At retail, the cost rises 2 or more times. So, in an online store, a gourmet product can be bought for 2000-3000 dollars. As for the so-called bloody nests, the cost of a kilogram sometimes reaches 10 thousand dollars.
The price of swallow's nest soup ranges from $ 10-100. Swift saliva drinks start at $ 3.
It is worth noting that unscrupulous sellers artificially tint the product to increase its value, or even imitate it from agar-agar. However, there is a testing system for quality assurance. Therefore, you need to buy a delicacy only from a trusted supplier.

Some delicacies are distinguished by an interesting bright taste, others amaze with their unusual taste, and still others cause ambiguous feelings, sometimes not even the most pleasant ones. As for the nest created by the swift swift, we are not talking about any special sensations. It does not have a pronounced taste and smell, and after cooking, it resembles jelly in texture.
Before eating, the product must be prepared in such a way as to preserve the maximum useful properties. And there is a special technology for this. It is noteworthy that boiling and heating in the microwave reduces the nutritional value and makes the swallow's nest completely tasteless.
Bird's nest processing technology:
- Outwardly, the product resembles a spider web vermicelli, which may contain feathers, droppings and other foreign elements. You need to get rid of such garbage. What cannot be removed at this stage can be removed after further processing.
- Then the nest must be placed in a deep plate and filled with hot water. Within 5 hours, it is necessary to drain the cooled liquid and refill with a clean hot one. During this time, the "cobweb" swells. In this case, the product can increase several times.
- The next stage is treatment with an alkaline solution. First, we dilute a little soda in warm water and fill the nests. After a few minutes, drain all the liquid and rinse with running water.
- It should be brought to readiness in a water bath, so that vigorous boiling does not destroy nutrients.
It is recommended to eat dishes with swiftlet nests no more than 2 times a week. The best time for this is morning and evening, when the body is able to assimilate the maximum amount of minerals and vitamins. The portions should be small so as not to overload the digestive system.
Store the product that has not yet been processed in a cool, dry and dark place, but not in the refrigerator. The shelf life is from 3 months to a couple of years. Cleaned and treated nests can be placed in the freezer in individually wrapped portions and stored for up to 1 year. When stored in the refrigerator, the finished product is edible for 2 weeks.
