Usually, it is difficult for plants to be completely standardized. Plants have their own growth rules. With changes in various factors such as soil, temperature, light, and irrigation, the colors and states of plants will also be different.
For another example, the leaves of kale in summer are basically fresh and green, while most of the leaves planted in winter are dark green.
Secondly, kale is used as the raw material for plant extracts. In order to maintain its original coloring and nutrition, it is difficult to achieve complete standardization without addition. If different parts of kale are used for processing, there are also differences in the products presented.
Depending on how finely the kale powder is ground, the color of the powder will vary.
If the particles of kale are too fine, the color of the kale powder will be whitish, and its water solubility is also strong. If the particles are too thick, the color of the powder will be dark and the water solubility will be poor.
Overall, no matter how the color of the kale extract powder changes, the aroma presented is always a light vegetable freshness with no other off-notes.
