Blackcurrant Powder Introduction

Blackcurrant extract is an active substance extracted from blackcurrant fruit, with rich pigment content, especially a large amount of anthocyanins. It has a variety of pharmacological activities, such as promoting the biosynthesis of rhodopsin, improving circulation, anti ulcer, anti-inflammatory, and can significantly improve eye fatigue. It also contains rich unsaturated fatty acids, among which linoleic acid has the highest content. It has the effects of lowering blood pressure, blood lipid and anti atherosclerosis. It can also inhibit platelet aggregation, reduce serum cholesterol, increase linoleic acid synthesis and soften blood vessels. It is a good therapeutic agent for cardiovascular diseases. As the extract has many unique chemical components, it has a very important application in the beverage industry and medicine. It is a superior raw material for brewing, extracting natural pigments and producing cosmetics, drugs and food.

Blackcurrant Powder Pharmacological action

1. Blackcurrant Powder Antioxidant effect

Anthocyanins and phenols in blackcurrant extract have antioxidant activity, which depends on the number, position and degree of conjugation of hydroxyl, as well as the existence of power supply and absorption groups in the ring structure. Anthocyanins have strong antioxidant activity, which can reduce the risk of atherosclerosis. Phenols can inhibit the oxidation of LDL. Flavonoids contained in blackcurrant leaves also have antioxidant activity and the ability to remove active oxygen free radicals, and their antioxidant effect increases with the increase of the amount added.

2. Blackcurrant Powder Antihypertensive effect

The extract of blackcurrant fruit has antihypertensive activity. In the study on the effect of blackcurrant fruit on the smooth muscle of thoracic aorta in mice, it was found that the extract of blackcurrant can increase the synthesis of nitric oxide, and then relax the vascular endothelium by antagonizing H1 receptor in the endothelium, so it has antihypertensive effect. Black currant γ- Linolenic acid can inhibit the formation of hypertension in primary hypertensive rats. Its antihypertensive effect is different from that of increasing the response of the body to noradrenaline and angiotensin II, and also different from the changes in the pressor response caused by the mechanism of intracellular calcium ions.

3. Blackcurrant Powder Antiarrhythmic effect

Black currant seed oil can prevent arrhythmias in aged rats. Myocardial ischemia in rats can cause the sensitivity of persistent ventricular fibrillation, which increases with age. This sensitivity can be reduced by taking blackcurrant seed oil containing polyunsaturated fatty acids. At the same time, this mechanism of action may also be related to the metabolism of linolenic acid into arginine and then into myocardial arachidonic acid substances.

4. Blackcurrant Powder Effect on vision

The anthocyanins extracted from blackcurrant have good effects on visual function, and can be used as an effective drug to treat myopia and glaucoma. The main effect of anthocyanins on photoreceptors is to regenerate rhodopsin.

5. Blackcurrant Powder Lipid lowering effect

Blackcurrant juice can prevent the increase of serum triglyceride, total cholesterol and low-density lipoprotein cholesterol in mice caused by high-fat diet, and significantly increase high-density lipoprotein cholesterol, which has the effect of reducing blood lipids in experimental hyperlipidemia mice.

6. Blackcurrant Powder Anti fatigue effect

The consumption of energy and materials is an important reason for fatigue. Blackcurrant extract can promote glycogen storage or reduce glycogen consumption, reduce energy consumption, and has a certain anti fatigue effect.

7. Blackcurrant Powder Other functions

The acidic high molecular weight galactose isolated from blackcurrant seeds can inhibit the adhesion of Helicobacter pylori to human gastric mucosa. The polymers of these sugars can block the surface receptors of Helicobacter pylori, thus inhibiting its interaction with the specific binding factors on human stomach, thus playing a role in protecting the stomach.
