Abstract
Noodle is a food product which is highly consumed by Indonesian
people, although it does not provide enough nutritional balance for the
consumers. On the other hand, flaxseed (Linum usitatissimum L.) contains high
amount of nutritious components but its utilization in food industries is still
very limited. Therefore, this research was aimed to investigate the effects of
flaxseed flour concentration towards physicochemical properties, consumer
preference and nutritional composition of the noodle. Initially, three types of
cooking method (steam, boil and steam-boil) were applied in order to obtain
the most proper cooking method. Boiling was chosen since it resulted in noodle
with better texture characteristics. The subsitution of flaxseed was conducted
at four levels (10%, 20%, 30% and 40%) and the best formulation was selected
based on the most preferred sample determined through hedonic test on color,
aroma, taste, texture, aftertaste and overall parameter. Noodle with 20%
flaxseed flour concentration was chosen as the most preferred formula and it
was further incorporated with three different types of hydrocolloid (guar gum,
carboxymethyl cellulose and konjac glucomannan) at three different
concentrations (0.2%, 0.4% and 0.6%) in order to improve the quality of
noodle. Noodle added with konjac glucomannan at 0.4% concentration level
was selected as the best formula. The nutrition composition consisted of
65.14% moisture content, 4.92% protein, 5.8% fat, 0.43% ash, 1.56% dietary
fiber, 22.15% carbohydrate and 0.0036% omega-3 fatty acid, 0.0082% omega-6
fatty acid, as well as 0.58% omega-9 fatty acid. In comparison with commercial
fresh wet noodle, the incorporation of flaxseed flour to noodle was able to add
beneficial nutrients such as omega-3, 6, 9, dietary fiber and protein.
