Is the anthocyanin in blueberry in the skin or in the pulp? Both skin and meat exist.
Blueberries are blue-purple because they are rich in anthocyanin, which is a water-soluble natural pigment widely found in plants in nature. Generally speaking, judging which part of a food contains anthocyanins can be determined according to the depth of its fruit color. For example, the skin and meat of blueberry are blue-purple, so it can be seen that anthocyanins contain some pulp, but the skin is much darker than blueberry pulp, so the anthocyanin content is more.
Is the cream on blueberry skin anthocyanin? number
The frost on the surface of blueberry is a layer of natural blueberry powder formed during its growth, which is condensed from fructose solution, which can reduce the water loss rate of blueberry fruit, just like the frost on the surface of grape.

Will blueberry heating destroy anthocyanins? I will.
Because anthocyanin is a heat-sensitive active substance, it is not heat-resistant. If blueberry is made into jam and eaten at high temperature, anthocyanins are easily oxidized and decomposed, which reduces the edible value, and the active substances such as vitamin C contained in blueberry will also be destroyed when heated above 60 degrees. Therefore, if you want to play the role of blueberry anthocyanin, it is best to chew it directly.
Will anthocyanins disappear after blueberry freezing? number
Anthocyanin is a heat-sensitive active substance and a water-soluble polyphenol flavonoid. Its special structure and chemical composition endow anthocyanins with various biological activities. These active substances are sensitive to temperature, and will be inactivated when the ambient temperature exceeds a certain limit, that is to say, the dead, such as lactic acid bacteria and probiotics, are all heat-sensitive active substances and cannot be heated, otherwise they will lose their main functions. But anthocyanins are not afraid of cold, and blueberries preserved at low temperature can be greatly preserved.
