To store fresh turmeric for a longer period of time, you can freeze the pieces in portions. A rootstock can be stored in sand or soil at around 10 degrees Store in a dry place at 120°C. The roots can be dried out using heat and then processed into powder. This can be done dry using an electric coffee grinder.

Ingredients - Nutritional values - Calories

The turmeric rhizome contains essential oils with anti-inflammatory effects. The yellowish color is caused by curcumin or its derivatives (curcuminoids), which make up to 5.4% of the rhizome. ¹⁹ The most important chemical Components include curcumin, demethodycurcumin and bisdemethodycurcumin. ³

Unfortunately, there are no nutritional values for raw turmeric in the databases we use. There are studies in which you can find some nutritional values. ^1,2 Unfortunately, some of the data are contradictory, such as values for amino acids ³ that are far too low compared to known values. for ground turmeric. For this reason, we have not listed some nutritional values - or, like the amino acids, we have calculated and stated them ourselves in relation to the amount of protein.

Effects on health

Turmeric is used in folk medicine, especially in Ayurvedic and Traditional Chinese Medicine (TCM). There it is used to treat various ailments. There are no studies conducted on turmeric in Western medicine that show a healing effect. Underline the effect.

In TCM, turmeric is effective against stomach pain. In Indonesia, turmeric is considered a traditional remedy, especially for strengthening the immune system, as a prevention against infections and respiratory diseases.

Turmeric is not a superfood, but it does have health-promoting properties. What is turmeric good for? In general, turmeric stimulates digestion, reduces flatulence and has a positive effect on fat digestion. ²

Curcumin, the most studied ingredient in the spice turmeric, modulates a variety of signaling molecules that cover a wide range of effects in the human body and animal models. These include anti-inflammatory, antioxidant, hepatoprotective, chemopreventive, chemotherapeutic, antiproliferative, wound healing and antiparasitic effects. ¹³ Read more under "Use as a recognized medicinal plant".

Dangers - Intolerances - Side effects

Pregnant women, breastfeeding women and children under 12 years of age should not consume turmeric regularly or in large quantities, as there are hardly any study results on the effects or side effects for these groups of people. However, turmeric is harmless in moderate quantities. A high consumption of turmeric stimulates not only affects digestion, but it can also cause gastrointestinal problems or inhibit blood clotting. This is why people with haemophilia in particular should clarify before taking turmeric.

Use as a medicinal plant

Turmeric and its effects are interesting for scientific studies, but not always clear, as curcumin contains PAINS (Pan-Assay Interference Compounds), which are believed to cause false results in chemical tests. ¹⁷

Some yellow dyes such as curcumin have anti-cancer, antioxidant and anti-inflammatory effects, according to some authors. ⁷ However, there are also studies that suggest that curcumin breaks down the tumor suppressor protein p53, which therefore has possible cancer-promoting properties. ⁸ However, this is controversial, since in In 2006, the opposite effect was found in breast cancer cells, where the p53 concentration increased in curcumin-treated cells. In addition, no scientific evidence of these mechanisms has yet been provided in human subjects. In mice, there were positive studies on the effect against cystic fibrosis, but no positive effect in humans. ⁹

Curcumin has an influence on bone metabolism. In mice, it counteracts a loss of bone density caused by estrogen deficiency. It is still unclear whether curcumin promotes bone health in humans. ^11,12 An anti-inflammatory effect of curcumin has been demonstrated in knee osteoarthritis, where it inhibits the enzymes cyclooxygenase-2, lipoxygenase and NO synthase. ⁶

Since we usually consume very little turmeric and, above all, the bioavailability of curcumin is very low, in vitro studies are difficult to transfer to humans. ^4,5 In order to increase the bioavailability of curcumin, it is necessary to Piperine, a component ofblack pepper, although interactions are to be expected. ^10,15 According to an in vivo study, curcumin attenuates fluoride-induced neurotoxicity. ¹⁶

Ecological footprint - animal welfare

To produce 1 kg of turmeric, approximately 1657 litres of water are required. ²⁴ However, the source cited here does not indicate whether the value refers to powder or the fresh tuber. The production of powder requires a lot of energy, as the tubers either Cook for up to 6 hours or cook for several hours. ²⁵

Due to its special environmental requirements, turmeric has only been cultivated sporadically in Europe. In Austria, for example, it has been possible to cultivate organic turmeric in an unheated foil tunnel. ²⁵ When buying, you can therefore pay attention to regionality. If turmeric comes from organic farming, then No synthetic fertilizers or insecticides are used. Since these have a harmful effect on the environment, organic products are preferable to conventional ones, both in powder and fresh form.

The use of turmeric-based essential oils in agriculture has already shown good effects against various plant pests such as insects or mites in individual studies. Such an approach could be a good alternative or at least an option for reducing the use of synthetic plant protection products in the future. ²⁶

Worldwide occurrence - cultivation

The turmeric rhizome comes from South Asia, where it is still found wild today, especially in Indonesia and Sri Lanka. It is cultivated mainly in the tropical parts of Asia and Africa. Turmeric grows wild in South Asian forests (eg in India and Indonesia).

Cultivation - Harvest

If you like to enjoy turmeric raw and fresh, you can grow the plant yourself - organically. A piece of organic turmeric root is all you need. The root is left completely open and germinates. This works best if you first let the root germinate for 8 to Soak in water at room temperature for 12 hours. However, the germination location should not be too moist to prevent mold from forming.

After planting, water the root a little. After two to three weeks, you should see a sprout appear. Curcuma forms a false stem and large leaves. In warm areas, the plant can be kept in the garden from June to August. The temperature can also be kept at night. not fall below 15 degrees Celsius. ¹⁴ In cooler regions, turmeric must be overwintered indoors or in a heated conservatory.

When the seedling has reached a few centimeters, plant it in a wide pot or in a vegetable box with potting soil. The turmeric seedling should point upwards and protrude slightly from the soil. A partially shaded place with room temperature and mostly moist soil without waterlogging would be ideal. Oxygen must be able to reach the roots.

After about nine months, the plant should have formed new rhizomes (roots). In winter, you can harvest ¹⁴ or propagate. Once the flowers and leaves have wilted, you can carefully dig out the rootstock.

If you want to multiply the plants again, you soak them again and let them germinate. This can be done at either end of the root and will first show a green colour. This way you can divide the root to grow several plants. However, the cut should first be Let them dry for a few days before planting them at a depth of about 5 cm. This is the method without prior germination in the air.

Curcumin is used as a reagent for the detection of boron in the form of boric acid and in acidic solution produces the red dye rosocyanin.

Since turmeric (Kurkume, Curcuma, not: Cucuma) is relatively inexpensive as a powder, counterfeiters often use it to dilute saffron powder; caustic soda helps to check this. When the alkaline lye is added, the extract of saffron threads diluted with turmeric turns red; without turmeric it would retain its yellowish color. The flower of the turmeric plant is cream to pink and long-lasting, which is why it is popular as a cut flower. ¹²
