Dried SCOBY and Red Cabbage Pigment

I. Material

SCOBY1 piece, 8-10 cm diameter
Red Cabbage Dye: Purple Color250 mL
Red Cabbage Dye: Blue Color250 mL
Tools: Plate, Glass Jars

II. Procedure

1. Dry SCOBY on a plate for 7-10 days until completely dry.

2. Dip one side of dried SCOBY into purple-colored dye. Hold for approximately 25 seconds inside the dye to maximize absorption without letting it become too rehydrated.

3. Repeat on the other side of the SCOBY with the blue-colored dye.

4. Lay SCOBY back on plate for 48 hours, or until dry again.

5. Pour red cabbage dyes into separate glass jars and place in the fridge until next use.

III. Results

The purple cabbage dye has a vibrant pink pigmentation on the SCOBY, however the blue dye does not dry blue, and actually turns a light brown. There are also white spots that the blue dye formed on the SCOBY. These issues are potentially due to the fact that the blue cabbage dye is made with baking soda, and the SCOBY does not react well with that. In the spots where the blue dye did seem to take, it turned green which is likely because of the yellow tint of the SCOBY mixing with the blue pigment. It is unknown why some spots kept color while the rest faded to brown.

Other Observations: Dip dying in red cabbage dye does not make the SCOBY mold.

Disclaimer: Drying times may vary depending on the level of humidity in the air.
