Today we would like to take the opportunity to introduce our newly created “Life Science” business unit, which already started its business activities at the beginning of 2021! The new Life Science division at Leiber stands for health, technological expertise and innovation. It includes all activities related to the business fields of Health and Fermentation!
What is our motivation?
One of the major issues nowadays is the social coexistence of our society on our planet. If we look at forecasts about the world population in 2050, we expect more than 10 Billion inhabitants. Issues of health care, food security and alternative ways of countering the serious depletion of fossil fuels or, for example, environmental pollution become more and more important. For this reason, we at Leiber have the duty to contribute to these increasing challenges in the future, to be continuously able to operate successfully on the market. We pursued a clear strategy for more than 65 years to act for an innovative and sustainable future. One could almost say “with wise foresight”!
Key technology = Biotechnology!
Biotechnology is the key driving technology for global economic development. The economical & targeted production of important valuable substances supported by microorganisms (fermentation) already began in the early years of the 20th century. Biotechnology is already a fix solution in the health industry, food and beverage industry, for baby food, in animal nutrition, agriculture, cosmetics, textile and plastics industries as well as in fine chemicals! Biotechnology is already the decisive engine for new, innovative and sustainable solutions. And this is exactly where our Leiber products offer valuable solutions!
That’s why Life Science!
With the newly created Life Science business unit, our expertise at Leiber will be further strengthened and enhanced! The focus will be on expanding our product by developing new, innovative and target-oriented products, but also on exploring new and innovative application areas in health and fermentation business. Our objective is to meet the increasing demands by offering suitable products and solutions for the diverse and versatile areas of applications. The interface to science plays a major role Therefore we have several cooperation’s with external partners like universities or prestigious research institutions. Over the last decades we gained an enormous expertise in order to refine the pure, natural raw materials of the brewer‘s yeast into creative and innovative premium products for humans and animals! We want to proceed this way and continue to write the success story of Leiber!
We are looking forward to proceed this way and continue to write the success story of Leiber!
Additive Solutions Pty Ltd is responsible for positioning the Health products in Australia and New Zealand. Additive Solutions already has a partnership with the Food business unit for many years and is looking forward to the further expansion of the collaboration.
CK Chemtrade Services Pty Ltd will be responsible for developing sales activities in the South African market. Both companies belong to the Barentz Group, with whom Leiber GmbH is collaborating successfully in Italy for many years.
With these two new collaborations, Leiber GmbH optimizes its international distribution network and further expands the growing market for healthcare products.
We are looking forward to a successful cooperation!

The previous, long-standing business unit director, Mr. Eike Hagemann, left the company at the end of August in order to address himself to a new professional challenge. Mr. Hagemann led with great commitment the division and achieved various success-stories.
Ms. Kreutzer, who already worked for Leiber GmbH as Key Account Manager EMEA Food for many years, is delighted about her return to Leiber and the new challenge: “I am looking forward to the task of positioning our Yestimun® on the global market. We will strategically realign with established and new business partners and focus on the further development of our portfolio.”
We are looking forward to a successful cooperation!

We are attending Vitafoods Europe this year. The annual nutraceutical exhibition takes place from 7th – 9th May in Geneva, Switzerland.
At Vitafoods Europe 2019 we are presenting an innovative product at the New Product Zone, which contains our immune supporting ingredient Yestimun®. It’s called Soria DefensUp and it’s a syrup.
The syrup is suitable for children and supports the natural immune defence. Based on our Yestimun® Beta-Glucan and standardised plant extracts of echinacea, black currant and propolis, fortified with vitamin C and zinc, the syrup has effective immune-enhancing properties. It is completely free of alcohol and sugar.
Free tasting samples are available at our booth! Please contact us, if you want to make an appointment to get more information about Yestimun® Beta-Glucan, studies and news.
We would be happy to welcome you at our booth C40!

From 27th until 29th November Leiber GmbH presented its immune ingredient Yestimun® Beta-Glucan for functional foods and food supplements at the HI Europe in Frankfurt, a leading event for nutritional ingredients.
We showcased a quite new product from one of our customers, which includes bovine colostrum, vitamins, minerals and Yestimun®. Bovine colostrum is a liquid secreted by the mammary gland after birth. The product supports the effects of Yestimun® by maintaining the proper function of the immune system. Furthermore it protects cells from oxidative stress.
At the innovation tour about “healthy mind & body: cognitive & immune health” we informed the visitors about our latest study results. Besides the reduction of severity of cold symptoms the study showed, that (1-3), (1-6)- β-D-glucans from brewers‘ yeast have a positive effect on blood pressure and joy. It is discussed that the mode of action for this effect refers to the selective production of the natural messenger substance “Interleukin-10” by immune cells. An increase of this messenger substance is also linked to the prevention of depression.
Yestimun® Beta Glucan from brewers’ yeast for a healthy mind and body!

We are attending at Health Ingredients Europe this year. Europe’s leading health, natural and nutrition show is taking place from 27th until 29th November in Frankfurt, Germany. Yestimun® will be present at booth 8A70.

We would be happy to welcome you at our booth 8A70!
We were attending the Polish MeetUp conference on Food Supplements on Thursday, 18th October. It was perfectly organized by our Polish distributor PK Components and the Faculty of Food Sciences of the University of Warzaw (WULS-SGGW).
The conference was addressed to producers as well as distributors of food supplements and functional ingredients, including personnel of R&D, purchasing, quality, marketing employees, scientific-research personnel and representatives of national sanitary inspection bodies and people fond of food supplements.
At the MeetUp there were 15 speakers in four sessions. Each session was led by a chairman. Mr. Eike Hagemann, Business Unit Director Health, and Dr. Jan Winters, Business Development Manager EMEA, were active in the session about scientific and business aspects of yeast beta-glucans. Mr. Winters was chairing the session of the conference. Mr. Hagemann talked about the topic “Yeast Beta-Glucan: Turning science into business”.

Reseachers from the University of Aberdeen, Scotland investigated the properties of GRAS and Novel Food approved immune ingredient Yestimun® when added to the fermented milk product “yoghurt”.
What the scientists found out is really worth mentioning: The addition of Yestimun® (0,4 %) during yoghurt production showed highly significant and practically relevant reduction of fermentation time (-25 %). This result is economically interesting for the functional food industry, because of the possible reduction of production costs and time.
But that´s not all: Researchers also found that syneresis decreased with added Yestimun® (Syneresis denotes the expulsion of liquid whey from yogurt and is a primary defect often related to consumer acceptability). Other parameters also improved (e.g. hardness, total work done, adhesive, force, adhesiveness). Viscosity, color and titratable acidity stayed unaffected. From the consumer view it is also important that an added substance does not disturb sensory demands. The Scottish scientists could show that 0,4 % Yestimun® added during yoghurt production had no effects on the sensory properties.
Overall these findings lead to the question about the mechanism of the effects. This was not objective of this study but will be investigated at a later stage. One mechanism can already be excluded, by meaning that Yestimun® may be a substrate for the fermentation bacteria. In earlier studies we could determine that Yestimun® beta-glucan cannot be metabolized by fermentation bacteria, which could be shown by using Bifidobacterium breve Strain JCM1192 as an example.
Finally it can be stated: Yestimun® is a multifunctional ingredient. It helps consumers to enhance immune capacity and supports the production process. All in one!

The immune ingredient Yestimun® Beta-Glucan finally achieved a new regulatory status. After being sold for 15 years officially as normal food ingredient, the regulatory status now changed to “Novel Food”.
During the last years some beta-glucans have been sold as normal food while others have been categorized as Novel Food ingredient. This caused lots of regulatory discrepancies and discussions with authorities and customers. To have an equal competition with other Novel Food registered beta-glucans and to make the regulatory aspects easier and better understandable, Leiber GmbH finally decided to make a Novel Food application for Yestimun® as well.
“There have been several reasons for making an own full application and not just a substantial equivalence”, explained Eike Hagemann, Business Unit Director Health at Leiber GmbH. “The most important aspect was to expand the use levels and food categories for Yestimun® in comparison to already authorized yeast beta-glucans.”
The own Novel Food application for Yestimun® includes use levels up to 1500 mg per day in food supplements. These dosages are safe and give more possibilities for different product concepts. “The new Novel Food approval will make regulatory issues easier for our customers, especially in countries, where the authority’s opinion has been a big challenge before”, says Hagemann.
Now the regulatory status is officially confirmed by the European Authorities and should be accepted everywhere (Commission Implementing Decision (EU) 2017/2078). Furthermore the process of Novel Food Authorization also included a complete safety assessment of Yestimun® and confirms the high quality and safety of the ingredient for functional food and supplement applications. In combination with the ongoing interest and trend to immune supporting products we can look forward to new interesting products including the immune ingredient Yestimun® from brewers’ yeast. You find the commission implementing decision here: http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv:OJ.L_.2017.295.01.0077.01.ENG&toc=OJ:L:2017:295:TOC.
