Pineapple is a well-known fruit and can be found abundant in traditional markets, especially during harvest season. Consumers are fond of this fruit not only because of its delicious taste, but also because of its high vitamin and calorie content which is good for the health. Pineapple is often consumed as fresh fruit as well as processed food and beverages.

The productivity of pineapple does not necessarily yield good price. At harvest season, the price is very low and lots of wastes are incurred in the market place and producing centers.

To overcome this problem, a technology has been developed to process fresh pineapple into nata de pina. By adding Acetobacter xylinum, the sugar component in pineapple juice can be changed into a substance which is called nata de pina.

Processing of Nata De Pina


Pineapple juice, 10 liters
Diammonium phosphate (DAP), 30 g
Sugar, 4.8 kg
Glacial acetic acid, 0.2 liters
Acetobacter xylinum, 1 liter


Knife and cutting board
Pan and stirring spoon
Plastic tray


1. Prepare all the materials
2. Mix and boil pineapple juice, DAP, sugar, and glacial acetic acid.
3. Let the juice cool in a plastic tray, and then add starter Acetobacter xylinum and cover with paper.
4. Fermentation lasts for 14 days and nata layer will be formed thereafter. Cut the nata into size 1 x 1 x 1 cm, wash and boil.
5. Soak the nata in water for one night, and change soaking water repeatedly to eliminate acid taste.
6. Add 40% sugar solution, essence, and benzoic.
