carboxymethylcellulose, 1 egg and water was
combining manually to form dough. The dough was
then sheeting, combining of sheets, resting, rolling
and cutting, followed by boiling and drained. Three
levels of lemon pepper powder, 0,5%, 1% and 1,5%
(flour based) were applied for investigation.
The sensory assessment includes tasting of lemon
pepper-flavoured noodle for the intensity of the taste
and aroma, followed by overall acceptance using the
structure 5-point hedonic scale. Evaluation session
was held at room temperature and normal lighting
condition involving 12 trained panelists.
2.3.2 Lemon Pepper-flavoured Meatball
To prepare meatballs at laboratory condition, to 1 kg
chicken meat, were added tapioca flour 500g, garlic
50g, salt 20g and water 200 g. Lemon pepper was
firstly added during the mincing of meat. Minced
meat, flour, salt and garlic were mixed to form batter.
The batter was then formed into small ball-shapes in
size of 2-2,5 cm diameter, then cooked in boiling
water until the meatballs were floated. The meatballs
were then drained, cooled and packed before use.
Lemon pepper powder in the amount of 1, 2, 3, 4 and
5% of the total mass formulation were applied for
investigation.
The meatballs were subjected to sensory
evaluation for colour, aroma, taste, toughness and
overall acceptability using hedonic scale rating 1-7 to
assess the differences. Sensory acceptability of lemon
pepper-flavoured meatballs was conducted using the
structure 7-point hedonic scale. Thirty untrained
assessors comprising student of Faculty of
Agriculture participated in this study.
3 RESULT AND DISCUSSION
3.1 Drying Temperature
Drying temperature significantly affected water
content, aroma and taste of the lemon pepper powder.
The initial average moisture content of fresh lemon
pepper was 67-70%. The moisture content of dried
products was 15.20%, 13.48%, 12.54% and 14.20%
when drying process took place at a temperature of
40, 50, 60 and 70
o
C respectively. The higher drying
temperature led to a significantly lower water content.
However, it was not the case at drying temperature of
70
o
C, for no significant different between moisture
content of lemon pepper powder when drying at 40
o
C
and 70
o
C. It is possibly the case hardening took place
at the level of temperature above 60
o
C and led to a
higher amount of water retained in the fruit during
drying time.
The dried product was characterized by a brown
colour. The darkening of the colour of dried sample
could be due to high temperature during dehydration
in addition to black colour of the lemon pepper seeds.

Lemon pepper powder retained the intensity of its
native aromas after the drying process. According to
Prusinowska and Smigielski (2015) drying method
affect the losses of essential oils and antioxidant in
herbs and spices, and they found that freeze drying
more essential oil of dried herbs in comparing to sun
drying and oven hot air drying. Our experiment
indicates that the range of temperature 40–70
o
C by
using a hot air oven could preserve the native
compounds responsible for taste and aroma.
However, the intensity of aroma and taste were
decreased as drying temperature was increased and a
note of woody aroma was appeared in the powder.
Based on sensory evaluation, we decided to apply
drying temperature of 60
o
C to produce lemon pepper
powder used as flavouring for subsequent application
on food. This is in accordance with the finding of
Napitupulu et al. (2020) that oven drying at 54
o
C for
8h was the most appropriate processing method to
preserve the flavour of lemon pepper.
3.2 Cuisine Application
3.2.1 Lemon Pepper-flavoured Noodle
Noodle is one of the famous foods in Indonesia and
across Asian countries. Recently, many variations of
noodle have been developed by applying substance
that bear compound that provided functionalities.
Noodle flavoured with 0,5% lemon pepper had
only a slight taste and aroma of lemon pepper, and
leave almost no specific sensation of spicy bitter,
stinging and burning taste when eaten. Higher
concentration of lemon pepper led to a more
significant lemon pepper taste and aroma, but only at
