Jackfruit pulp could be processed into jackfruit concentrate in strips and puree forms. The former is used to flavor jackfruit bar, sweet potato candy, and tart; while the latter is used to flavor jackfruit leather and pastillas.
Dehydrated Jackfruit
The dehydrated jackfruit is a nutritious snack item from ripe jackfruit pulp. It is golden yellow to golden orange and has a chewy texture with a sweet and sour taste. It is safer than the other dried fruit products because it is free from sulfite preservatives, which may trigger allergic reactions in some consumers. It is the only sulfite- free dried jackfruit product in the market.
Vacuum Fried Jackfruit
The vacuum fried jackfruit is a nutritious snack item from ripe jackfruit pulp that is yellow to golden brown. It is sweet and crunchy. It is processed at low temperature (below 100oC) under vacuum thereby maintaining its sensory and nutritional qualities. It has no added sugar and preservatives . It is the only vacuum fried jackfruit product in the market that uses ripe pulp.
Jackfruit Tart and Pastillas
The processing of jackfruit tart and jackfruit-flavored pastillas is a technology developed for small and large- scale processors. The processes are simple and do not need sophisticated machines and food ingredients.

5.) Spread the drained pulp on drying trays lined with nylon mesh to prevent from sticking on aluminum trays. Dry at 70o – 75oC for 8 hours.
6.) Interchange drying trays every hour for uniform drying. Pack in 0.004 in. thick in polypropylene bags at 90 grams net weight.
7.Store the packed products in wooden screen cabinets in a cool dry place.
Vacuum Fried Jackfruit
1.) Slice open the ripe jackfruits and take out the pulp by separating the seeds and the rags.
2.) Blanch 20 kg of the pulp in boiling water until the pulp turns soft to touch (67 kg of fresh jackfruit will yield around 20 kg pulp).
3.) Let the blanched jackfruit to cool. Then pack in polypropylene bag and freeze.
4.) The following day, take out the frozen jackfruit pulp. Deep fry in frying chamber. The vacuum pump will be turned on to reach the required vacuum of 25 inch Hg or higher. The frying operation per batch is 2.5 hours at 90oC.
5.) Place the fried product inside a clean sackcloth and centrifuge for 7 minutes. After centrifuging, allow to cool and pack in 0.004 inch thick polypropylene bags at 50 g net weight. One batch could yield 120 bags. Store the packed products in wooden screen cabinets in a cool dry place.
