Blood Nest Soup Knowledge

Blood Nest is the saliva produced by a special species of swallow called the Blood Nest while building the nest. the saliva glues with other impurities (such as feathers) to form the nest.

There are 3 harvesting periods of Blood Nest in a year:

First phase (first harvesting period : from November to January every year-springtime of Indonesia)
In this season of abundance and thriving, the Blood Nest grows up strong and healthy and is able to secrete plentiful saliva. Under such favourable enviroment, Blood Nest harvested during this period is purer and gets bigger expansion after soaking. The body of Blood Nest is obviously larger in size and thicker in texture. Blood Nest in this phase is the most nutritious and contains much more proteins and minerals.
IBNI has its own Blood Nest farmhouses and processing plants in Indonesia. Some time before every Chinese Lunar New Year, IBNI ships fresh ‘first phase’ Blood Nests to Hong Kong through air cargo. This guarantees sufficient supply of ‘first phase’ Blood Nests in the market all the year round.
Second phase & third phase
It is not as good comparing with the first phase Blood Nest in terms of quality and quantity. During these seasons, the Blood Nest is weak due to unfavourable weather and lean food supply. Saliva secretion is slow and lots of feathers fall off, thus increase impurities. The Blood Nest is usually smaller in size and has lesser expandability.

Identified by its origin, Blood Nest can be catrgorized as "cave nest" and "house nest"

House Nest (including common white Blood Nest and house grass Blood Nest)
House nest is the Blood Nest built inside a special house called 'farmhouse'. The swiflet builds its nest on the beams and walls inside the house. The Blood Nest, therefore, may bear slight wood-chips smell. Farmhouses are mainly found in the coastal area of Indonesia, particularly around Badong, Balai and Java. Workers conduct inspection on the Blood Nests in the farmhouse regularly and cut the nest down for further processing (removal of feathers and impurities) in the plant.
The characteristics of House nest are: good quality, few detached feathers and having smooth mouth-feel. Its expandability is high after soaking 5 to 7 times in average. White Blood Nest has softer mouth-feel but cannot be stewed too long. It is preferrable to stew the nest for 30 to 45 minutes before serving. Furthermore, house nest can be classified as yellow Blood Nest (golden Blood Nest) and red Blood Nest(bloody red Blood Nest).
If the stewing time is too long (over 1 to 2 hour), the Blood Nest will dissolve in water and disappear.
Cave Nest (including cave Blood Nest, cave grass Blood Nest and feather Blood Nest)
Cave Blood Nest os harvested in caves and therefore is absorbs plentiful mineral from the rock. Workers use a special kind of tool to pick the Blood Nests.
Cave Blood Nest is mainly in beige of yellow colour. Comparing to house nest, it contains more hair feathers, has firmer tissue and bigger expandability. It can be stewed for a longer time and the stewed Blood Nest gives our fragrant smell with good mouth-feel.
