A recent study into the beneficial qualities of porcine haemoglobin has revealed some interesting results.1
Normally discarded as a by-product of the meat industry, the haemoglobin was hydrolysed using pepsin, AS1398 neutrase, trypsin, flavorzyme, papain and alcalase. The peptic hydrolysate exhibited the highest antioxidant activities out of all the hydrolysates and was separated using ultra filtration membranes and consecutively using a variety of chromatographic methods. Ultimately, a novel antioxidant peptide from porcine haemoglobin (APPH) was purified. APPH demonstrated higher lipid peroxidation inhibitory ability than α-tocopherol as a positive control (P
The study concluded that APPH would be a beneficial addition to functional food and pharmaceuticals, rather than labelled as a waste product.
