Whether it's a giant raisin or a regular raisin that costs more than ten dollars a pound, its nutritional value is extraordinary. Its flesh, skin, and even the core are rich in nutrients, so it can be said that the whole body is a treasure. Raisin flesh contains a large amount of glucose and fructose, easy to be absorbed by the body, can be quickly converted into heat, restore energy, eliminate fatigue. In addition, the pulp contains special amino acids, which help to enhance brain function. The skin of raisin contains resveratrol, which helps to prevent vascular occlusion because it prevents blood from clumping and depositing in the blood vessels, thus reducing the chances of heart disease, stroke and other vascular diseases. We eat grapes usually spit out the kernel, because it is hard and tasteless, but it turns out that the small grapes kernel, is exactly where its nutritional value. Grape seed kernel contains rare antioxidant substances in plants - anthocyanins. Anthocyanins are powerful because they can remove free radicals that damage normal cells, prevent cellular aging, increase immunity and protect the arterial blood vessel wall collagen destruction and stiffness. If you don't want to eat the kernel of the raisin, you can also drink red wine Raisins are also known as "grapes"), because it squeezes the essence of the whole raisin even the kernel out of the whole raisin.

Raisin skins and seeds should not be eaten

Grape skins and seeds contain polyphenols, resveratrol, and other healthy ingredients, which have antioxidant and cardiovascular disease prevention effects.

Although rich in extremely high nutrition, they cannot be eaten. Because, the water solubility of these healthy ingredients is very poor. Trying to rely on teeth chewing, tongue stirring, saliva extraction and other methods to obtain these healthy ingredients, the effect is very poor. Secondly, grape skins and seeds contain a large amount of tannin, which, in addition to producing a strong astringent flavor, can cause damage to the digestive tract if eaten in excess.　

Healthy ingredients such as polyphenols contained in grape skins and seeds will be much more soluble in ethanol. Soak the grape skins and seeds in ethanol for many days, and these healthy ingredients can be extracted quite sufficiently. Therefore, if you want to ingest the grape skin, grape seeds in the "treasure", the correct approach is to crush the grape skin, grape seeds soaked in white wine for about two weeks (during which you can often shake), filter off the dregs, made of grape skin, grape seed wine, and grape juice blended drink.
