Jams, Marmalade

1. Taking a sample

Place 20-50 grams of jam/marmalade in a beaker and mix well with a plastic spoon. Apply 2-3 drops onto the prism surface.

2. Measuring Method

 ● Hand-Held Refractometers 

1) Apply a few drops of jam/marmalade onto the prism and close the daylight plate. Make sure the jam/marmalade is spread evenly over the prism surface.

2) Look through the eyepiece. Read the boundary line where the blue and the white color meet. This is the Brix (%).

* Suitable for jam/marmalade during cooking. 

* After measuring, wipe the prism with a wet tissue.

* Wash with lukewarm water after measuring highly viscous samples.

* Low-sugar jam and marmalades have become popular recently. Some products show values between Brix 35-40%
