Microencapsulation of Minerals with Vegetable Oil Coatings
The coating process of Mineral Salts, especially of Iron Salts can be done with different coating materials. Dr. Paul Lohmann®, your expert for tailor-made Minerals, offers sustainable produced hydrogenated or non-hydrogenated palm oil as standard coating materials. Now the product range is extended with sunflower oil and rapeseed oil. Both oils are fully hydrogenated and tasteless and offer the same taste-masking effects like the common palm oil.
The alternative coating materials show a better heat stability compared to the palm oil encapsulation. Temperature controlled release experiments show a release from the palm oil encapsulated product between 50 and 60°C, whereas the release from sunflower and rapeseed oil encapsulated products starts at 60°C. This allows the selection of the most suitable product, depending on the final application.
Drug release experiments in simulated gastric juice show a very similar releasing behavior of the different coating materials. The non-encapsulated product is completely dissolved after 20 minutes. The release rate from the encapsulated products is below 10% after 100 minutes.
Calcium Citrate superfine – best results in dairy products
With the newly developed Tricalcium Citrate 4-hydrate superfine, Dr. Paul Lohmann® found the answer to a high demand on a calcium citrate with a clearly reduced speed of sedimentation in dairy products and plant based milk alternatives. With this superfine powder, customers will be able to fortify their dairy products with calcium with a significant reduction of sedimentation during the production process.
The Research and Development department did a lot of application trials with Tricalcium Citrate 4-hydrate with different particle sizes like normal powder, micronized powder, fine powder and superfine powder. The products were tested on their performance in different kinds of dairy products, cream and oat milk. The test results showed that the superfine powder was the best performing product within this series of tests, with the slowest sedimentation velocity and the smallest amount of sediment at the bottom of the testing tubes. Another positive effect is the improvement of taste and mouth feeling by using the superfine powder.

Next Level for soft Chewing Calcium Tablets
DC mineral salts are designed for the compression of tablets as part of an existing tablet formulation. The use of DC grade products eliminates the need of an in-house wet granulation step and saves cost and time for the tablet manufacturer.

Calcium Carbonate DC 97GA
Calcium Carbonate DC 97GA is designed for direct compression to soft chewing tablets with neutral taste and pleasant mouth feeling. Besides maltodextrin, corn starch or PVP as binding agents, gum arabic is a perfect addition to the DC granulate product line. The product is dust-free and free-flowing, and permitted for food and food supplements. Due to the high calcium content tablet size can be reduced.
- Granulate for direct compression with gum arabic
- High calcium content
- Free-flowing product quality
- Pleasant chewing sensation
