Take clean fresh pineapple juice yield, such as skin, thorn, core of more than 45% of scraps, squeezing, fruit juice filter chip. The filtrate adds 0.025 0.05% benzoic acid, and 0.05% kaolin for adsorption. Dispatch kaolin adsorption material with saturated sodium carbonate solution pH6.7-7.0, and 5% sodium chloride, stirring after filter. Take the filtrate hydrochloric acid pH4.8-5.1, and ammonium sulfate, let stand for precipitation, precipitation decompression drying, is the bromelain. Process is as follows: pineapple scraps (press) to SAP (kaolin) adsorption, adsorption content (elution, filter) and eluent (salting out) - salting out content (centrifugal) - wet crude enzyme cake (dissolving, filtering) to clarify the content (precipitation), wet enzyme (dry) and high-quality goods
