A NEW METHOD TO PRODUCE MARINE PROTEIN HYDROLYSATE WITH ULTRA-LOW HEAVY METAL CONTAMINATION AND IMPROVED PHYSICAL PROPERTIES

摘要

An improved method to produce soluble marine protein hydrolysate powder with ultra-low heavy metal contamination. This invention relates to a production method that comprises occluding the heavy metal contaminants present in a soluble marine protein hydrolysate solution produced by enzymatic hydrolysis of industrial fish or fish off-cuts, into a lipid particulate structure and separating these particles from the aqueous protein layer. This invention further relates to a method for separating the fatty particulates from the soluble marine protein hydrolysate aqueous layer using a continuously operating automatic disc scrapper or membrane filtering system and evaporating and drying the aqueous fraction into a healthier and safer protein hydrolysate powder for direct and indirect human consumption.
