Two major components of pineapple bromelain, purified to electrophoretical homogeneity, appeared to have the same oligosaccharide group consisting of n-glucosamine, n-mannose, D-xylose, and L-fucose in ratios of 2:2: 1: 1. By exhaustive proteolysis of the bromelains, glycopeptides containing only Asx, Glx, and Ser were obtained. Periodate oxidation, methylation, and glycosidase digestion showed...

In this work, bromelain is recovered from triturated pineapple stem and rind (usually kitchen waste) through the precipitation process with alcohol at low temperature. The temperature control is crucial to avoid the irreversible protein denaturation and consequently improving the precipitation yield. The process is carried out in a fed-batch system, so that its dynamic nature poses challenging ...

Background Delayed onset muscle soreness (DOMS) is muscle pain and discomfort experienced approximately one to three days after exercise and is believed to be a result of microscopic muscle fiber tears. The Bounce-BackTM product is a combination of several dietary supplement ingredients which have individually been shown to improve the inflammation and pain associated with DOMS (digestive enzym...
