Previous reports employed gel electrophoresis together with liquid chromatographic strategies to discover some widespread adulterants in edible chook's nest.[seven][24] During this analyze, gel electrophoresis and liquid chromatography ended up utilized for protein profiling and amino acids reports of cave and household nests, and Many others samples which include white fungus, fish swimming bladder, jelly and egg white. Each and every from the samples had a novel protein profile which will be mirrored to the protein gel and these results were supported because of the chromatographic Assessment. Gel electrophoresis also was used to recognize and differentiate the edible hen's nests dependent on their geographical origins.[seven]

To find out Electrical power worth, samples were weighed, along with a pellet was formed by a tabletop pellet press. The sample pellet was positioned inside of a sample cup linked to the heating component.
The filtrate was transferred to a separating funnel and shaken with 20 mL of distilled h2o. The combination was permitted to settle right away, along with the ether portion was removed and dried within an oven at 60°C for eight hours. The residue body weight was lipid, which was expressed as a share.
Unfortunately, Ravi Sankaran died in 2009 right before he could begin to see the fruits of his initiatives. His university student Shirish Manchi still left and not using a mentor, took up learning these birds and The good news is continues to do so. He was conducting pioneering reports within the ecology, breeding success and behaviour of the species in the Chalis-Ek caves. When I visited him the Andamans in February 2012, I had been impressed to discover Shirish’s pupil, the young Akshaya Mane, residing in a remote jungle hut with 10-twelve forest guards and local nest protectors.
