All About Ginger Extract
I. Origin of Ginger Extract
Ginger, the underground stem or rhizome of the plant Zingiber officinale, has been used medicinally since ancient times in Chinese, Indian and Arabic herbal traditions. In China, for example, ginger has been used for more than 2,000 years to aid digestion and treat upset stomach, diarrhoea and nausea. Since ancient times, ginger has also been used to treat arthritis, hernia, diarrhoea and heart disease. It has been used as a culinary spice for at least 4,400 years in its native Asia, where it grows in fertile, moist tropical soil.
II. Uses of Ginger Extract
Ginger root is widely used as a digestive aid for minor stomach upsets and is recommended by professional herbalists to prevent or treat nausea and vomiting caused by motion sickness, pregnancy, etc. It has stomachic and anti-gastric ulcer, biliary, hepatoprotective, cardiac, platelet aggregation inhibiting, anti-sickness, anti-tumour, central suppression, immunity enhancing, antibacterial, insecticidal, anti-inflammatory effects and also has strong antioxidant capacity. Used as a food additive; used in the preparation of flavours.
Ginger is a Chinese medicine, now many shampoo products, bath products contain ginger ingredients, in fact, ginger as a Chinese medicine in pharmacology proved to have certain benefits for hair. Ginger has ginger spice, which can also promote blood circulation and increase vascular permeability to prevent hair loss. For patients with hair loss, such as those with alopecia areata, topical application of ginger slices can promote blood circulation and hair growth locally. Pharmacologically, ginger has been shown to have a good bactericidal and antibacterial effect and can be used as a disinfectant, so rubbing ginger on the surface of localised objects or skin has a certain antibacterial and antipruritic effect.
III. Effects of Ginger Extract
1. Nausea and vomiting
Ginger extract has been shown to reduce the symptoms of motion sickness associated with travel by car or boat. Initial double-blind clinical trials found that ginger may reduce nausea caused by surgical anaesthesia, and a preliminary study suggested that ginger may help prevent chemotherapy-induced nausea.
2. Motion sickness
Many studies have shown that ginger is more effective than placebo in reducing symptoms associated with motion sickness. In a study of 80 novice sailors (prone to motion sickness), those taking powdered ginger extract experienced a significant reduction in vomiting and cold sweats compared to those taking a placebo. Similar results were seen in a study of healthy volunteers.
3. Effects on the cardiovascular system
Ginger extract has an excitatory effect on the vasomotor centre of anaesthetised cats, directly stimulating the heart. Chewing 1 g of ginger (without swallowing) in normal subjects resulted in an average increase in blood pressure of 1.49/1.87 kPa, with no significant effect on pulse rate. Ginger allyl given as a sedative injection to rats resulted in a transient decrease in blood pressure, followed by an increase and later a sustained decrease in tridirectional changes, with the ascending effect inhibited by trazodone and the descending effect inhibited by cutting the vagus nerve.
4. Anti-inflammatory effect
In addition to its ability to reduce nausea and vomiting, ginger extract has long been used in traditional medicine to reduce the effects of inflammation. In fact, many herbalists have used ginger to treat health problems associated with inflammation, such as arthritis, bronchitis and ulcerative colitis. In a recent study of 261 patients with osteoarthritis (OA) of the knee, those who took ginger extract twice a day had less pain and needed less painkillers than those who took a placebo.
5. Digestive tonic effects
Ginger is considered a tonic for the digestive tract, stimulating digestive function and nourishing the intestinal muscles. This function may help move substances through the digestive tract and reduce irritation of the intestines. Ginger may protect the stomach from the damaging effects of alcohol and non-steroidal anti-inflammatory drugs (NSAIDs) and may help prevent ulcers.
6. Cardiovascular health
Ginger extract may also support cardiovascular health by making blood platelets less sticky and reducing platelet aggregation. A small number of preliminary studies suggest that ginger may lower cholesterol and prevent blood clotting. All of these functions may protect blood vessels from blockages and the damaging effects of blockages, such as atherosclerosis. However, more research is needed to understand whether these preliminary findings will ultimately be beneficial in humans.
iv. development prospects
As an important spice in people's lives, ginger is not only widely produced and consumed in China, but also exported to the world, but the processing of ginger in China is still in the form of primary products such as fresh ginger and ginger powder, which causes a great waste of ginger resources. Therefore, it is of great practical value to study the preparation method of ginger oleoresin and its properties. The modern process of producing ginger oleoresin not only has a much higher quality than its traditional spice form, but also has a broad-spectrum antibacterial effect, inhibiting both bacteria and fungi, especially the inhibitory effect on fungi is significantly stronger than that of potassium sorbate. Therefore, it is expected to reduce or partially replace the dosage of chemical synthetic preservatives in future food processing. At the same time, its multiple dosage can also simplify the processing process, with economic rationality and broad application prospects.
Data shows that the market growth rate for ginger extract is showing a significant trend. According to Market Research Future, the global ginger extract market is expected to grow at a CAGR of 5.1% to reach $1,333.2 million by 2025. Of this, the food and beverage segment is expected to reach $632.3m by the end of 2025. Currently, ginger extracts are used in a wide range of applications in the food and beverage industry, including carbonated soft drinks, beer mixes, energy drinks, distilled beverages, tea drinks, bakery products, syrups, confectionery and ice cream.
In terms of consumer-related ginger-flavoured finished products, some of the more common flavour pairings are pure ginger, ginger lemon, ginger grapefruit, ginger honey and ginger peach, while other flavour pairings are less common. Some platforms study the flavour pairing of ginger and eggs, ginger and rhubarb ( rhubarb ), ginger and mint, etc. can be a good match, ginger flavour is special, plasticity is very strong, no matter the product category or flavour development, ginger concept product innovation have more room to play.
On the other hand, as one of the key markets for global functional foods, Japan is a global trendsetter for functional ingredients and application innovation in terms of product innovation. For example, in early 2023, Indena Japan launched a new ingredient called "MITIDOR ®", which is a combination of standardised ginger and Acmela extracts. The ginger extract contains 2.4-3.9% of standardised gingerols and total gingerols, while the Acmela extract contains 0.3-0.6% of standardised chitosan. The recommended daily dose is 350 mg twice daily.
Studies have shown that this ingredient is able to control the oxidative response that causes inflammation and thus has an effect on joint pain. The specific mechanisms of action include direct action through interaction with the CB2 receptor and indirect action through action on the FAAH enzyme involved in physiological pain processes. These findings suggest that the ingredients in MITIDOR ® are a promising new option for applications related to joint pain relief.
With the increasing demand for a healthy diet and the continuous improvement and expansion of ginger extract processing technology, it is believed that its application in the food field will become more and more widespread.
