NEWS FEED & ADDITIVE MAGAZINE August 2024 91 PPG released new data about the performance benefits of its PPG Flo-Gard™ precipitated silica products as high-capacity carrying agents in bulk food and feed applications. The research compared the carrying capacity of PPG’s precipitated silica to maltodextrin, a common carrying and bulking agent. Results showed that PPG Flo-Gard silicas provided more than 40 times the carrying capacity of maltodextrin. PPG Flo-Gard silica is used in food free-flow and carrier applications to add flavors and nutrients, improve product performance and maximize manufacturing productivity. It is odorless and tasteless, imparting no additional flavors or calories to food. As a carrying agent, it absorbs liquids, oils and fats and produces a free-flowing powder that can be found in animal feed premixes and many powdered and granulated food products. “Precipitated silicas have been used extensively as free-flow and anti-caking agents, but they are also very effective as carrying agents due to their high surface area and porous structure,” said Matt Faber, PPG research manager, Specialty Coatings and Materials. “This new research demonstrates their capacity and versatility, and how precipitated silicas can help manufacturers increase production efficiency by achieving higher additive concentrations and greater storage and transportation flexibility.” Read more>> New Research: PPG Flo-Gard provides high carrying capacity in feed This year, the Inhouse Farming - Feed & Food Show will take place for the first time at one of the world's leading trade fairs EuroTier organized by the DLG (German Agricultural Society). The event will be from the 12th to the 15th of November in Hanover, Germany, with the second day being Aquaculture Theme Day. Agricultural professionals can obtain a full overview of all types of self-contained closed systems for food and feed production. In addition to insects, vegetables, herbs and medicinal plants, today's indoor farms also produce aquatic candidates such as fish, crustaceans and aquatic plants in Controlled Environment Agriculture (CEA) systems. The rapid growth rates of global aquaculture production are impressive. According to FAO 2022, 130.9 million tons of fish and seafood were produced in aquaculture, surpassing capture fisheries (SOFIA, Fao 2024). Asia is the leading region. The EU countries, and therefore also Germany with traditional pond farming, are stuck in stagnation, limited by restrictions, environmental protection and nature conservation requirements. As early as the 1980s, the lack of new water rights for fish production, pollution of natural waters and the desire for manageability led to the development of so-called Recirculating Aquaculture Systems (RAS). Fish and other aquatic organisms were now grown and marketed independently of rivers, streams and lakes using filter systems and water treatment with minimal use of fresh water. This is not a simple technological solution. Each fish species has its own farming requirements and specially adapted feed. Some RAS systems soon had to close their doors again, as the recirculation and heating of the water was extremely energy-intensive and the marketing of the fish was not optimal.
