Lactoferrin is also widely used in infant formulas, sports nutrition, and a wide range of dietary and immune supplements.</p>
<p xmlns="http://www.w3.org/1999/xhtml">To improve access to this fast-growing market, the Company intends to expand its executive team to include a Chief Scientist. This newly added role will play a key role in sourcing and prioritizing strategic scientific investments, joint ventures and new product launches with a goal to expand and enhance the Company&#39;s product portfolio and revenue generating capabilities. The Company has identified a strong leading candidate at a leading US academic institution for this Chief Scientist role and is in advanced negotiations to fill the role in the near term.</p><p xmlns="http://www.w3.org/1999/xhtml">Today, commercially produced lactoferrin is produced primarily through two methods:</p><ul xmlns="http://www.w3.org/1999/xhtml" type="disc"><li xmlns="http://www.w3.org/1999/xhtml"><b xmlns="http://www.w3.org/1999/xhtml">Extraction from Bovine Milk (dominant method):</b></li><ul xmlns="http://www.w3.org/1999/xhtml" type="circle"><li xmlns="http://www.w3.org/1999/xhtml">Whey or skim milk from traditional dairy processing is highly purified using membrane filtration and ion-exchange chromatography to isolate bovine lactoferrin.</li><li xmlns="http://www.w3.org/1999/xhtml">Because milk contains relatively little lactoferrin, very large volumes of milk are required, making production expensive and supply constrained.</li></ul><li xmlns="http://www.w3.org/1999/xhtml"><b xmlns="http://www.w3.org/1999/xhtml">Precision fermentation (emerging):</b></li><ul xmlns="http://www.w3.org/1999/xhtml" type="circle"><li xmlns="http://www.w3.org/1999/xhtml">Genetically engineered microorganisms (such as yeast or fungi) produce recombinant lactoferrin in fermentation tanks.</li><li xmlns="http://www.w3.org/1999/xhtml">This approach offers greater scalability, consistency, and potentially lower costs, although commercial adoption is still in its early stages.</li></ul></ul><p xmlns="http://www.w3.org/1999/xhtml">The Company is focused on delivering world class products that require the highest quality lactoferrin for the Chinese market. The target market is currently the world&#39;s largest lactoferrin market, representing 22% of the estimated $300 million in annual global demand today. The market is expanding rapidly, at an estimated 9% annually, and is expected to exceed $100 million in annual sales in China alone by 2030 and $500 million globally.
