Research Reveals PPG’s FLO-GARD Silica's High Capacity for Bulk Food & Feed

PPG has unveiled new findings on the performance advantages of its PPG FLO-GARD™ precipitated silica products, which serve as high-capacity carrying agents in bulk food and feed applications. The study analyzed PPG's precipitated silica against maltodextrin, a common carrier and bulking agent, to determine their relative capacities. The results demonstrated that PPG FLO-GARD silicas offer over 40 times the carrying capacity of maltodextrin, highlighting their superior efficiency and effectiveness in managing bulk materials. This significant improvement underscores the value of PPG’s advanced silica technology in enhancing bulk handling processes.

PPG Flo-Gard silica is utilized in food free-flow and carrier applications to enhance flavors and nutrients, optimize product performance, and boost manufacturing efficiency. It is both odorless and tasteless, ensuring it does not alter food flavor or add extra calories. As an effective carrying agent, it absorbs liquids, oils, and fats, resulting in a free-flowing powder. This product is commonly incorporated into animal feed premixes and various powdered and granulated food items, improving their processing and functionality.

Matt Faber, PPG's research manager for Specialty Coatings and Materials, emphasized the dual role of precipitated silicas in the industry. Traditionally used as free-flow and anti-caking agents, these materials also prove to be highly effective as carrying agents due to their high surface area and porous structure. Faber’s recent research highlights the versatility of precipitated silicas, showing their ability to enhance production efficiency by allowing manufacturers to use higher concentrations of additives. This advancement also improves storage and transportation flexibility, thereby optimizing the overall manufacturing process.

Adam Riley, PPG's global technical manager for Specialty Coatings and Materials, highlighted that PPG’s precipitated silicas offer benefits that surpass their immediate use. These silicas not only enhance the functionality of food service products and manufacturing processes but also support sustainability objectives. By facilitating the use of smaller packaging, they help reduce shipping costs and, consequently, lower the overall emissions linked to food production. This dual benefit aligns with broader environmental goals and underscores the value of integrating sustainable practices into product development and supply chain management.
