3.6.1. Total Soluble Solids (TSS) and pH Measurement

Each group of strawberries was collected. Juice was obtained by homogenizing strawberries in a blender, and then filtering through a cheese cloth. The pH values of samples were determined with a pH meter (Sartorius PP-50, Goettingen, Germany) [47]. The TSS was determined using a digital refractometer (Atago, Tokyo, Japan).
