The extraction of pineapple (ananas comosus) fruit juice with high concentration of bromelain enzyme

---

Pineapple has proteolytic enzyme called bromelain. Bromelain has several medicinalrneffect, recent research even prove the effectivity of Bromelain in treatment ofrnHIV/AIDS patients. The problem with pineapple fruit is their short shelf life as thernfruit spoil easily. Instant drink powder has relatively longer shelf life and thus it is arnsuitable product type for this. In this research the instant drink powder was producedrnwith spray drying, and freeze drying. Another problem during drying of fruit juicernwas their stickiness so maltodextrin was used to avoid it. Drying in high temperaturernlike spray drying could potentially destroy the bromelain so maltodextrin and saltrn(ZnSO4) were added before the spray drying process. For freeze drying, its lowrntemperature helped to protect bromelain enzyme so no salt was added. The addition ofrnsalt had negative effect which rendered them unsuitable for instant drink powder,rnalthough the enzyme activity was protected. Maltodextrin could also give protectionrnof the enzyme but excessive maltodextrin addition can hinder the enzyme activity. Forrnfreeze drying process, the enzyme was protected because the drying process wasrnperformed at low temperature. The downside was its long process time and costlyrnprice. Because of that spray drying process with the addition of maltodextrin 15%rn(w/w) was preferred for the production of pineapple instant drink powder
