NO DETERGENT
During the cleaning process we do not use any cleaning or cleaning chemicals. We use saddle washing water which is certified by Pasteur Institute (because chlorine in tap water can degrade bird's nest). Because it is difficult and time-consuming to clean the bird's nest by hand, some establishments can use the cleaning agent, although it is not toxic, but it can reduce the nutrition of bird's nest.
NO STAINING
Natural nests can have pure white, ivory, orange, yellow, brown, red... bleaching or staining according to consumer tastes may impair the nutritional value of the nest.
NO ADDITIVES
Natural oats are lightweight, so people can use fiber or other foods to fill in to increase weight, some consumers prefer crispy, tough oats... You can use borax. All of these substances degenerate the swallow's nest. We absolutely do not use any additives.
NO PRESERVATIVES
Pure bird's nest can last for a long time in the natural environment, but if there are fillers or additives to increase weight, color, smell, you must use more preservatives, VinBirdNest absolutely no preservatives used.
