THE CHALLENGE: Ensuring the quality, safety, and stability of powdered food products is crucial. Manufacturers need to overcome challenges in maintaining free-flowing properties and consistent quality throughout production, storage, and transportation.
THE SOLUTION: Silica is an effective anti-caking agent and free-flow aid. By coating the surface of powder particles, silica reduces interparticle interactions and absorbs moisture, fats, and oils, thereby preventing caking and lumping.
THE SMART EFFECT: By ensuring consistent quality and stability, Evonik’s silica and silicates enhance the overall efficiency of food production, helps reduce food waste and contributes to consumer satisfaction.
What can Evonik silicas and silicates do for you?
At Evonik, we understand the headaches associated with manufacturing powdered food products. Caking and lumping can create serious problems during production, processing, dosing, storage and customer use. Additionally, caking and bad flowability can cause unnecessary product loss and requires a lot of water, and energy for cleaning of equipment. Evonik has solved these problems for hundreds of customer applications with its outstanding lineup of high-performing silica and silicate products. Through advanced product technology and custom application development, Evonik stands ready to remedy your issues today. 80 % of all food products have components produced in a dry state at some point of their processing.1
Due to their fine particle size or stickiness, some powders show poor flow properties and cake upon storage which makes handling and proper dosing difficult. Hygroscopic substances such as fruit powders, table salt, vegetable extracts, and spice mixtures, are a few of many examples. For all those ingredients, ZEOFREE®, SIPERNAT® precipitated and AEROSIL® fumed silica offer an efficient low-cost way to meet this challenge and improve sustainability.
