Date Issued 13 June 2019
Abstract This study aimed to optimize the process parameters for vacuum-fried Tinumbaga
jackfruit bulb chips. Specifically, it established the effects of vacuum frying parameters
on the color and texture acceptability, and Hunter L*, a*, b* values of vacuum-fried
Tinumbagajackfruit bulb chips; validated the predictive models for the vacuum frying of
optimum Tinumbaga jackfruit bulb chips; and evaluated physicochemical and
microbiological profiling of the optimized vacuum-fried Tinumbaga jackfruit bulb chips.
Results show that vacuum frying temperature and time had a significant (p<0.05) effect
only on texture acceptability. Optimum vacuum frying temperature and time of 85 ℃ and
20 min, respectively, were generated. Validation experiments revealed that the generated
model and acceptability model can be used to accurately predict the texture acceptability
of vacuum-fried Tinumbaga jackfruit bulb chips. The optimized product had a pH of 5.12
± 0.07, moisture content of 0.12 ± 0.04 % , water activity of 0.33 ± 0.01, and Hunter L*,
a*, b* values of 56.41 ± 0.07, 14.45 ± 0.01, and 58.75 ± 0.11, respectively, with
acceptable yeast and mold count (i.e. <100 cfu/g). The results of the study indicate that
Tinumbaga jackfruit variety can be processed as an acceptable vacuum-fried jackfruit
bulb fruit product with a great potential as an alternative to atmospheric deep-fried
snacks.
