COCONUT CHIPS DRYING

2. INTRODUCTION
Coconut is major plantation crop of Kerala.
The pure coconut meat contain
Moisture - 36.3%
 Coconut chips is a value added product of
coconut (Cocos nucifera) kernel
Avg 120-150g chips ,from one coconut
Shell life of coconut chips -6 months

3. PROCESS FLOW
Coconut(10 month
matured coconut kernal)
Removal of shell
Removal of Testa
Cutting in to pieces
Slicing of Kernel
0smotic Dehydration (1
hr/40 min)
Drying (4-6 hrs)
Packaging

4. DRYING METHODS
Osmotic dehydration
Hot air tray drier (Drying)

5. Fully matured husked nuts are baked in an
oven at 175 °C for 15-30 minutes
osmotic dehydration by soaking in juice
solution (beet root /carrot juice with sugar
syrup) for one hour
The color and sugar treated coconut slices
were dried at different temperatures viz.,
60°C, 70°C and 80°C for 4-6 h.

6. The hot air tray drier was used for drying the
coconut slices.
The higher drying temperature (80ºC) took
only 3 h to dry the chips
The lower temperature (60ºC) required 5 h
drying time for the complete removal of
moisture.
 Samples were stored in laminated aluminium
pouches /LLDPE containers at ambient
temperature (~27°C) during the storage
period.

7. COCONUT CHIPS

8. CHARACTERISTICS – coconut chips
Not fried in oil
Crispy
No preservatives
No loss of flavour/nutrients present in
the kernel
Ready to eat as snacks
On rehydration chips are just like fresh
kernel
