Quality Changes In Carrot (Daucus Carota) And Malay Rose Apple (Syzygium Malaccense) Juice Blend During Ambient Storage.
ABSTRACT
Juices were produced from a
vegetable (Carrot) and a fruit (Malay rose apple) separately as well as their
blends in different proportions. Physicochemical, vitamin, microbial and
sensory evaluations were carried out on the samples using standard methods.
Results obtained revealed the following ranges and decrement of physicochemical
parameter for both the fruit and storage periods respectively: ph (3.31 to
4.23; 4.29 to 3.37), ash (0.37 to 0.53; 0.35 to 0.52%), specific gravity (1.12
to 1.07, 1.25 to 0.93g/ml), also ranges and Increment in: total titratable
acidity (1.13 to 2.29; 1.18 to 2.12%), total soluble solids (6.09 to 10.18;
7.29 to 8.71°Brix), and reducing sugar (3.64 to 4.80; 2.69 to 5.15%). Vitamin
content obtained were vitamin A (2.07 to 14.89; 11.57 to 6.04.igIg) and vitamin
C (17.35 to 39.68; 29.10 to 20.71 mg/100ml) for both the fruit and storage
intervals respectively. Sensory evaluation of the juice samples showed that the
products were acceptable for consumption (with respect to mouth feel, flavour,
taste, colour, and general acceptability) by the panelists. However, the (juice
blends of 50% Carrot + 50% Malay rose apple + 0.1% Potassium sorbate) sample
was the most acceptable. The microbial assessment of the samples showed that
all the samples contained
