Abstract:
In recent year, the demand for chicken meat is rising quickly. Spent hen meat could be used
to meet consumer demand. However, spent hen meat is low in physicochemical and
organoleptic properties. Therefore, the laboratory experiment was conducted to document
the effect of pineapple and papaya fruit extract immersion on the organoleptic and
physicochemical quality of grilled spent hen meat. The study was laid out with two
experiments. The treatments in experiment 1 were: control (E1T1), 10% (E1T2), 20% (E1T3),
and 30% (E1T4) of pineapple fruit extract immersion. The treatments in experiment 2 were:
control (E2T1), 10% (E2T2), 20% (E2T3), and 30% (E2T4) of papaya fruit extract immersion.
The spent hen meat was immersed for four hours at 4±1 0C and grilled. A complete
randomized design was used as an experimental design with three replicates.
Physicochemical parameters, including pH, marinade uptake, cooking yield, cooking loss,
and sensory parameters including smell, colour, appearance, taste, flavour, texture, and
overall acceptability were analysed for grilled spent hen meat. The data were analysed using
ANOVA with SPSS software version 25.00 and Duncan’s Multiple Range Test with a
significant level of 5%. The results of experiment 1 revealed that pH after cooking
(6.64±0.07) and cooking loss (60.06±1.52%) were significantly (p<0.05) higher for E1T1.
pH before cooking (6.40±0.02), marinade uptake (2.33±0.19%), and cooking yield
(59.48±1.20%) were significantly (p<0.05) higher for E1T2. Experiment 2 revealed that there
was no significant (p>0.05) difference between the treatments of pH before and after
cooking. E2T4 showed a significantly (p<0.05) higher value for marinade loss (0.88±0.13%).
E2T2 showed significantly (p<0.05) higher value for cooking yield (53.67±3.26%). Cooking
loss (60.48±3.80%) was significantly (p<0.05) higher for E2T1. Physicochemical analysis of
experiment 1 and 2 revealed that E1T2 and E2T2 had positive impact on spent hen meat.
Therefore, the comparison between E1T2 and E2T2 revealed that E1T2 had significantly
(p<0.05) higher cooking yield and marinade uptake. Results of the sensory analysis showed
that E1T2 received higher acceptance for sensory parameters including smell, flavour, taste,
texture, and overall acceptability. Finally, it was concluded that papaya and pineapple fruit
extract immersion influence the quality of spent hen meat. However, 10% pineapple fruit
extract immersion has a greater positive effect on the sensory and physicochemical quality
of grilled spent hen meat than other treatments
