The refractometer I ordered on Ebay arrived in the mail from Hong Kong. Yes! Now I can measure the relative nutrition of fruits and vegetables. It will take some practice before I learn how to identify which is which and to properly tool myself.
I tried it this morning. I got our reverse osmosis water and placed it on the prism. Viewed the measurement which read zero as expected in the operation manual that they have factory calibrated the refractometer.
My first experiment was with a pineapple. This pineapple with had for breakfast I bought in the market yesterday. The lady said this pineapple came from Tagaytay. So sample number 1 is a ripe sweet pineapple and it reads 10.5 Brix.
What is Brix? In the operation manual it says Brix Refractometer: It is developed for working with sugar related liquids, help monitor to control sugar concentrations in foods and beverages. Checking the ripeness of fruit in the field, verifying product quality after harvesting or controlling concentrations during processing and packaging, refractometers provide critical information to ensure product quality.
So I will be learning to use this tool to help us identify quality fruits and vegetable produce.
