How to make a colorful vortex

The practice of rainbow vortex is: put rainbow sugar at equal intervals, pay attention to the collocation of hue, and let the color of vortex jump.

In addition, there are:

1, use a convenient container to introduce warm water, the water temperature can be slightly higher, and the water surface is covered with sugar itself.

2, the color is slowly and evenly opened.

3. Vortex appears gradually,

4. The sugar body is transparent and the color is getting better and better.

5, stare big eyes and pay attention to observation, naturally there is a color vortex.

Because the pigment of rainbow sugar is integrated with the water phase, the water density around the sugar increases and the solution spreads to the surrounding places with lower density. When two adjacent sugar pigments are dissolved in water, the density is similar, and they will spread to the lower density area in the center of the plate, forming a rainbow vortex.

Rainbow sugar turns into rainbow when it meets water, because some water-soluble pigments in sugar dissolve when it meets water, so rainbow blocks appear. Edible pigments are divided into legal pigments and illegal edible pigments.

The national standard for food additives, 2760-20 14, does not stipulate illegal edible pigments, so it is not practical in food. Long-term intake may cause harm to human liver and nervous system.

The pigments listed in the national standard 2760-20 14 are all allowed to be used in food after strict toxicological tests. Used in a prescribed amount, it is harmless to human body.
