1. Thermal Nutrients

The content of carbohydrates, protein and fat per 100g of cranberries were 12.9g, 0.4g and 0.2g respectively. From its composition, cranberry is a low-calorie, green, healthy fruit. Dietary fiber. The content of dietary fiber in every 100g of cranberries is 4.6g. Dietary fiber has a preventive effect on cardiovascular and cerebrovascular diseases, diabetes, and cancer. In addition, dietary fiber can promote gastrointestinal motility, promote digestion, and prevent constipation.

2. Minerals

Cranberries are rich in minerals such as potassium, sodium, phosphorus, magnesium, and calcium. The contents of potassium, phosphorus, calcium, magnesium, and sodium in every 100g of cranberries are 8mg, 13mg, 8mg, 6mg, and 2mg, respectively. Cranberries are relatively high in potassium and relatively low in sodium, which can help lower blood pressure and protect the cardiovascular system.

3. Vitamins

Cranberries are rich in a variety of vitamins, especially the highest content of Vc. Per 100g of cranberries, the content of Vc reaches 13.3mg. Vc can prevent leukemia, promote collagen synthesis and reduce fatigue.


4. Phenolic compounds

The content of procyanidins per 100g of cranberries is 34.3mg, and the content of anthocyanins is 0.77mg. Procyanidins and anthocyanins are phenolic compounds. The former is a natural antioxidant that can scavenge free radicals in the human body; the latter is a water-soluble antioxidant that can scavenge free radicals, improve vascular circulation, and improve skin smoothness. In addition, cranberries are rich in phenolic acids, flavonols and other substances, which can inhibit the occurrence of cancer.

Health benefits of cranberries

1. Prevent UTIs

Studies have found that cranberry juice has adhesion to E. coli on the urothelial cells, so it can play a role in preventing urinary tract infections. The researchers used gene chip technology to focus on the mechanism of the PAC gene of cranberry in preventing urinary tract infection. Beauty, anti-oxidation, anti-aging. The high content of Vc in cranberries can be described as the king of fruits. Vc can promote the formation of collagen in the human body, and has the effect of beautifying the skin and reducing fatigue.

In addition, cranberries are rich in proanthocyanidins and anthocyanins, which can effectively remove free radicals in the human body and delay the rate of human aging. Protect the stomach and reduce gastric ulcers. Human infection with Helicobacter pylori can easily lead to chronic gastritis and consumptive ulcers. Relevant studies have shown that cranberry juice can inhibit the adsorption of Helicobacter pylori to human gastric mucus, thereby protecting the gastrointestinal tract and reducing the occurrence of gastric ulcers.

2. Protect the mouth

Cranberry can effectively inhibit the formation of gingival biofilm, thereby achieving the purpose of preventing and treating periodontitis. Studies have shown that the polyphenolic compounds rich in cranberries can inhibit the secretion of protease by periodontitis-curing bacteria; prevent the adhesion of Streptococcus mutans on the teeth, effectively preventing the occurrence of dental caries; reduce the adhesion of bacteria in the oral cavity and improve the oral cavity healthy.

What is lepidium meyenii used for？

Lepidium Meyenii also is called Maca, is a natural plant rich in high-unit nutrients and rich in 55 high-unit nutrients, protein, amino acids, unsaturated fatty acids, vitamins and trace elements, etc. Therefore, Lepidium Meyenii root extract can fully regulate the body's functions, including the 9 major systems of the human body, more than 400 tissues and organs continue to provide high-quality nutrients. Previously, people’s overbearing of Lepidium Meyenii root extract led to many people’s misunderstanding of this product. However, the ability of Lepidium Meyenii extract to promote sexual function is not entirely a marketing routine. Among them, Macaene and Macaamide are considered to be Maca. One of the effective substances with promoting sexual function in the extract. Through experimental research on erectile latency and erectile dysfunction in mice and rats, it was found that Lepidium Meyenii root extract can improve the sexual function of experimental animals. In the perio...

What are the applications of supercritical CO2 extraction technology in plant extraction?

  Supercritical CO2 extraction technology has the advantages of energy saving, purity, rapidity, high efficiency, and simple operation because it combines rectification and liquid-liquid extraction, and plays an important role in the extraction and separation of effective components of traditional Chinese medicine. 1. Extraction of volatile oil The volatile oil is sensitive to high heat, acid, and alkali, and is easily destroyed when extracted by traditional steam distillation, with low efficiency. At present, there is much research literature on the application of supercritical carbon dioxide to extract volatile oil, and the yield of the obtained product is high and the integrity of the components can be maintained. The researchers used organic solvent extraction (SE), steam distillation extraction (SDE), and supercritical carbon dioxide extraction (SFE-CO2) to extract celery seed oil. The results showed that the celery seed oil obtained by supercritical carbon dioxide extraction...
