Bioactive compounds, which are naturally produced in plants, have been concerned with the food and pharmaceutical industries because of pharmacological effects on humans. In this study, individual phenolics six legumes during germination antioxidant capacity from sprout extracts were determined. It was found that phenolic content significantly increased all legumes. Peanuts showed strongest both DPPH• (1,1-diphenyl-2-picrylhydrazyl) method reducing power assay (32.51% 84.48%, respectively)....

Background: Edible bird’s nests (EBN) are highly nutritious and valued food for their numerous health benefits. Consequently, high economic value increasing global consumption demand EBN have contributed to a rise in counterfeited issue. Currently, the common method identifying origin of edible bird is DNA barcoding PCR-based technique because limitations morphological identification methods; however, primers currently used PCR face specific challenges amplifying from nests. Thus, newly...
