燕窩是燕子吐出的營養豐富的唾液分泌物。此種膠狀分泌物是燕子築巢時的主要材料，而燕子築巢的地點通常選在如懸崖峭壁和深山洞穴等險峻的高處。

燕子的種類有三十多種，其中只有兩種金絲燕屬和一種侏金絲燕屬的燕子會生產可食用燕窩。爪哇金絲燕生產的可食用燕窩品質最佳，因為其顏色白淨且羽毛雜質最少。爪哇金絲燕只分佈於東南亞地區。燕窩的清潔處理過程相當繁複，一個人花八小時的時間只能處理約十個燕窩。

余仁生極濃縮無糖燕窩以上等珍品燕窩精製而成，本品口感濃稠香滑，老少咸宜。

Bird's Nest is the nutrient-rich salivary secretion of swiftlets. This gel secretion is an integral component to building the swiftlet nests, which are found in dangerous and highly inaccessible locations like steep cliffs, overhanging crags and deep caves.

Out of more than 30 species of swiflets, only 2 species of the genus Aerodramus and 1 of the genus Collocalia make edible saliva nest. Aerodramus fuciphaga is the swiftlet that produces the highest quality of edible Bird’s Nest, because its nests are white and clean with minimum feathers. It is found only in Southeast Asia. Tedious process of cleaning approximately 10 nests takes approximately 8 hour by a person.

The major components of Bird's Nests are its glycoproteins, carbohydrates and trace elements. Scientific findings by the researchers in Chinese University of Hong Kong discovered that epidermal growth factor (EGF) is present in Bird's Nests. EGF is a low Molecular weight polypeptide which provides beauty support.

The most abundant amino acids are serine, threonine, aspartic acid, glutamic acid, proline, and valine. When consumed, they help to provide general wellness.
