Market launch of world´s first LED-Vitamin D-Booster

After 2 years of intense research and development in cooperation with the University of Hohenheim (Germany), LUXIDUM ventured a great step further into Vitamin D-Boosting Process Optimization.

Two-stage UV LED type combinations were tested on vitamin D synthesis rate and further photoproducts
(eg. lumisterol, tachysterol, toxisterol, suprasterol) in mushrooms. Based on these results we developed
a completely new and patented LED technology approach: LED2D® technology.

Our technology consists of two narrowband high performance UV LED with different center wavelengths switched in series (type B and type C) leading to a two-stage vitamin D synthesis process:
          stage 1 Priming of ergosterol, the precursor of vitamin D
          stage 2 Opitimized biosynthesis of vitamin D
→ Highest yield of vitamin D
→ Lowest yield of undesired photoproducts

All our Boosters and main components incl. light systems are manufactured exclusively in Germany!

Two-stage UV LED type combinations were tested on vitamin D synthesis rate and further photoproducts (eg. lumisterol, tachysterol, toxisterol, suprasterol) in mushrooms. B/C wavelength combination was found to be the most efficient regarding vitamin D synthesis combined with lowest yield of undesired photoproducts.

Luxidum developed a completely new and patented LED technology approach for the production of Vitamin D-Mushrooms in the world´s first LED-Vitamin D-Booster: LED2D® technology.

Next launch of a LED-Vitamin D-Booster

We are proud to announce that a further LED-Vitamin D-Booster with our patented LED2D® technology has been put into operation in a production line at a German mushroom production site!

Luxidum’s Customers

Vitamin D Mushrooms

Luxidum offers fully automated customised Vitamin D-Boosters for the production of Vitamin D Mushrooms – the most innovative step forward in fresh mushroom products.

In 2016 Monaghan Mushrooms was granted the first authorisation for UV-treated Vitamin D button mushrooms as a Novel Food.

Since then, Walsh Mushrooms and Banken Champignons applied for authorisation through a costly and time-consuming application process.

However, the Novel Food regulation amendment (EC) No 2015/2283 became valid on 1.1.2018. All foods mentioned in the Novel Food Union List can now be placed on the EU-market by every company without any further authorisation process!

Vitamin D Deficiency

The Europeans’ average vitamin D intake is far below the recommended daily intake, mainly because there are so few food sources rich in vitamin D.

Vitamin D deficiency is a public health issue prevalent worldwide and is one of the key causes of osteoporosis and muscle weakness.

Furthermore, vitamin D deficiency is associated with:

  • cancer
  • cognitive impairment
  • cardiovascular diseases
  • autoimmune diseases
  • hypertension
  • infections

Vitamin D Sources

Few foods are naturally rich in vitamin D. Good sources include fatty fish such as salmon and tuna.

However, all mushroom species contain ergosterol, and upon exposure to UV light from the sun or artificial light, this provitamin D is converted through a photochemical reaction to vitamin D.

That´s why wild mushrooms can contain high amounts of vitamin D due to sunlight exposure. On the other hand, the vitamin D content of cultivated button mushrooms is minimal (<0.2 μg/100 g), because they are cultivated indoors without the benefit of sunlight.

Approved Claims by EFSA

Regulation (EC) No 1924/2006 sets the rules on the use of health or nutritional claims on foodstuffs based on scientific evidence. Health claims are any information on labels and advertising stating that health benefits can result from consuming Vitamin D-Mushrooms. The following claims have been approved by the European Food Safety Authority (EFSA) for Vitamin D-Mushrooms:

Nutrition Claims

  • High in vitamin D
  • Rich in vitamin D
  • Excellent source of vitamin D

Health Claims

  • Reinforces the body’s natural defences
  • Improves muscle strength
  • Important for healthy bones and bone strength
  • Enables normal bone formation
  • Important for good teeth mineralizationEssential for the absorption and utilisation of dietary calcium and phosphorus
  • Regulates cell division
  • Regulates the immune system
We offer Vitamin D-Boosters with different UV light technologies based on customer-specific requirements eg. pulsed UV light from Xenon or continuous UV light from mercury bulbs. Our aim is to offer stepfree adjustability of your mushrooms’ desired vitamin D content from 1 – 30 μg/100 g at the stage of end-customer sales together with very good reproducibility.

About the Founder

  • Dr. Paul Urbain is a pioneer in the field of “Vitamin D Mushrooms” research. As a nutritional scientist, he was in 2011 the first to demonstrate in humans that the bioavailability of vitamin D from UV-treated and vitamin D-rich button mushrooms can effectively cure vitamin D deficiency [1].
  • Since 2011 he has held the utility patent for the use of Vitamin D Mushroom Powder in different food products and supplements.
  • He recently directed a subproject entitled: “Exploration of novel vitamin D-enriched mushrooms and powdered mushroom-containing food products for prevention of vitamin D deficiency; efficacy and safety” within the EU’s 7th Framework Programme (ODIN) [2-4].
  • The project partner Monaghan Mushrooms of Ireland got in 2016 the first authorisation of UV-treated and vitamin D-rich button mushrooms as a Novel Food.
  • In 2017, he submitted on behalf of a large producer of button mushrooms in Germany, an application for authorisation to put Vitamin D-Mushrooms on the EU market under the simplified notification procedure.
