Grape skin pigment can be used as colorant for food and cosmetics. With its abundance of pharmacologically active substances and numerous health benefits, grape skin extract has become a sought-after supplement for individuals seeking to enhance their overall health.
Aogubio, a company specialized in the production and sale of pharmacologically active substances, raw materials and plant extracts, recognized the great potential of grape skin extracts. Committed to providing high-quality nutraceuticals and supplements to the pharmaceutical, food, nutraceutical and cosmetics industries, Ogu Biotech has harnessed the power of grape skin extract and incorporated it into its product line.
The biochemical and pharmacological activities of grape skin extracts have been extensively studied. The content of polyphenols in the skin of red grape is 25% ~ 50%, mainly anthocyanins, resveratrol and flavonoids. Grape skin red is anthocyanin pigment. Its main coloring components are malvidin (malvidin chemicalbook), peonidin (peonidin), delphinidin (delphinidin) and the glucoside of 3 '-methylate (petunidin) or cyanidin (cyanidin). These findings highlight that grape skin extract is one of the most potent antioxidants available, making it an excellent choice for fighting free radicals and inhibiting lipid peroxidation. Grape skin extract is also a very good antioxidant and anti-aging substance, which is very good in effect, and has high efficiency biological activity, so it can further delay the aging of the skin, such as some women who love beauty, through such extracts, it can also resist the aging of the skin, make the skin become younger, smoother, and restore the young state. By scavenging free radicals, grape skin extract protects body cells from oxidative stress, thereby reducing the risk of various chronic diseases.

These effects are attributed to the extract's ability to enhance blood flow, reduce inflammation, and prevent the formation of blood clots.
In addition, grape skin extract has anti-inflammatory properties, making it an ideal natural solution for people suffering from chronic inflammation. By inhibiting the production of pro-inflammatory molecules, grape skin extract can reduce inflammation and its associated symptoms, thereby relieving and improving overall quality of life. Grape skin extract has been linked to promoting brain health and cognitive function. The high concentration of antioxidants in grape skin extract can protect brain cells from damage caused by oxidative stress and support memory retention and cognitive processes.

AOGUBIO grape skin powder preparation method:
- (1) Wash, dry and crush the skins of red grapes (through a 40-mesh sieve) for reserve use.
- (2) Take 1000 grams of red grape skin powder, add 5000 grams of 50% ethanol, and stir and leach at 50 ~ 70Chemicalbook℃ for 1 ~ 2 hours after filtration.
- (3) After filtration, the filter residue is then leached with 50% ethanol 5000 grams, under the same conditions, and after filtration, the filtrate is combined twice.
- (4) The combined filtrate is evaporated and concentrated under reduced pressure, and ethanol is recovered at the top of the tower. Get the pigment from the bottom of the tower.
- (5) After filtering the pigment liquid, it is continuously flowing from top to bottom at the rate of 2 ml per minute through a columnar tower with an inner diameter of 3 cm and equipped with a large pore adsorption resin. Grape red pigment was adsorbed by macroporous resin. Chemicalbook then washes the adsorption column with water until the effluent is colorless.
- (6) The pigment is desorbed from the adsorption column to 95% ethanol by using 95% ethanol to flow from top to bottom through the column containing the adsorption resin at the same speed.
- (7) The ethanol was recovered by vacuum evaporation, and the concentrated pigment liquid was obtained from the tower kettle, and the grape skin pigment powder was prepared after vacuum drying.
Grape skin extract can not only be added to cosmetics or nutritional health products, of course, can be applied to the food industry, wine juicing grape skin is the raw material source of grape skin pigment, extracted grape skin pigment can be widely used in fruit wine, jam, beverage coloring.
