Abstract

The present invention relates to a method of preparing an extract from edible bird's nest, a bird's nest extract and uses of the bird's nest extract. The method comprises preparing an edible bird's nest (EBN) mixture; and contacting the mixture with an extraction solution to bind a molecule in the mixture, wherein the extraction solution comprises at least one binding moiety selected from the group comprising an opsonin binding moiety, a complement protein binding moiety, a lectin binding moiety, a ficolin binding moiety, a collectin binding moiety, and a pentraxin binding moiety.

Description

technical field [0001] The present invention relates to methods for preparing immune extracts from mixtures comprising bird's nest raw materials and optionally other materials, and extracts obtainable from these methods. Background technique [0002] Edible Bird's Nest (EBN) is a nest made from the saliva of swiftlets that occur naturally in Southeast Asia. These abandoned nests are harvested from the wild or from houses built specifically for swiftlets. EBN has been reported to exhibit multiple biological activities and nutritional values, including mitogenic response potential, epidermal growth factor (EGF)-like activity, anti-influenza virus, hemagglutination inhibitory activity, lectin-binding activity, improvement of bone strength and dermal thickness and hormone levels. Depending on the application, EBN can be processed differently. In order to clarify the biological function and medical function of edible bird's nest, people are conducting research.
