2.3. Juice preparation
Clean fresh strawberries of about 240 g were cut into smaller pieces, followed by blending in a blender (Phillips
E2371, Indonesia). The resulting strawberry pulp was then filtered to separate the solid residues from the liquid
concentrates. The liquid concentrates were then diluted by the addition of mineral water (1 : 4 v/v) in order to obtain
fresh strawberry juice. Four types of fresh strawberry juices were prepared namely juices A, B, C, and D. Juices A
and B were prepared without sugar addition, while sugar (5.5% w/v) were added into juices C and D. Juices A and C
