*2.7. Color Fruit Samples*

HunterLab Colormeter (HunterLab Labscan 600 spectrocolorimeter, version 3.0; Hunter Associates Laboratory Inc., Reston, VA, USA) was used according to the Granato and Masson [49]. Strawberry fruits from each treatment were measured at three equidistant points for L\* (lightness), a\* (redness), b\* (yellowness), while hue angle (h◦) was measured [(h◦ = tan<sup>−</sup>1(b\*/a\*)] for each sample.

### *2.8. Physicochemical and Bioactive Constituents of Strawberry*

### 2.8.1. Soluble Solid Content (SSC)

Firstly, in a mortar, the fruit samples were crushed then squeezed to acquire juice by hand. A digital refractometer (model PR101, Co. Ltd., Atago, Tokyo, Japan) was used to measure the soluble solid content (SSC) in the fruit juice.
