100,000U/G Food Grade Pineapple Extract Bromelain

Bromelain Enzyme (CAS No. 9001-00-7) is a natural mixture of proteolytic enzymes extracted primarily from the stems and fruit of the pineapple plant (Ananas comosus). It appears as a light tan to off-white, free-flowing micro-powder with a characteristic mild fruit odor. Containing a complex mixture of thiol endopeptidases, phosphatases, glucosidases, peroxidases, and cellulases, Bromelain is a versatile sulfhydryl protease that operates efficiently across broad pH ranges (4.5–7.5) and optimal processing temperatures (40-60℃).

Function

Bromelain functions primarily as a potent proteolytic agent, hydrolyzing interior peptide bonds in protein molecules to convert complex proteins into smaller, highly bioavailable peptides and free amino acids. It exhibits high selectivity for cleaving peptide bonds adjacent to basic amino acids, aromatic residues, and lysine. Beyond its catalytic protein-degrading properties, Bromelain displays intrinsic anti-inflammatory, anti-edematous, fibrinolytic, and immunomodulatory activities by inhibiting pro-inflammatory prostaglandins and promoting the breakdown of fibrin deposits.

Application

Pharmaceutical & Healthcare Industry

In pharmaceutical and nutraceutical formulations, Bromelain is widely incorporated into oral enzyme supplements to aid protein digestion, reduce post-operative swelling, and relieve joint inflammation associated with osteoarthritis. It serves as an active anti-inflammatory agent in sinusitis and trauma care, enhances the tissue permeability and absorption of co-administered antibiotics, and acts as a selective enzymatic agent in enzymatic burn debridement treatments.

Food & Beverage Industry

In commercial food processing, Bromelain is an effective natural meat tenderizer, breaking down collagen and muscle myofibrillar proteins to improve meat texture without causing over-softening. It is applied in beer manufacturing to prevent chill haze by hydrolyzing protein complexes, used in baking to modify gluten strength for improved dough extensibility, and employed in soy, dairy, and fish protein hydrolysis to produce functional flavor peptides.

Cosmetics & Personal Care Industry

In personal care formulations, Bromelain acts as a natural enzymatic exfoliator in facial cleansers, brightening peel masks, and skin-soothing formulations. It gently breaks down dead surface skin cells and intercellular keratin deposits without mechanical abrasion, refining skin texture and unclogging pores. Additionally, its anti-inflammatory properties help soothe irritated skin, reduce redness, and promote a radiant skin tone.
