Welcome to kasel group – Leaders in Sustainable Citric Acid Production
At kasel group, we are pioneers in developing cutting-edge, sustainable technologies for citric acid production. With a team of experts holding multiple patents in citric acid manufacturing, we lead the industry by implementing the most advanced and efficient production methods.
Our expertise lies in the selection and development of industrial Aspergillus niger strains with exceptionally high conversion rates across a variety of carbohydrate sources.
These unique strains, combined with our proprietary downstream processing techniques, set new standards for the global citric acid industry.
With decades of experience designing, building, and operating citric acid plants, Kasel Group is your trusted partner for state-of-the-art solutions.
Our Citric Acid Competence
• Tailored Strain Selection: We specialize in selecting Aspergillus niger spores optimized for each raw material, ensuring maximum yield and efficiency.
• Sustainability: We focus on reducing the carbon footprint throughout the production process, aligning with our commitment to environmental responsibility.
• Versatile Fermentation: Our use of bubble column and stirred-tank fermenters allows for a wide range of substrates, including sugar, corn, starch hydrolysate, beet molasses, and cane molasses, ensuring flexibility and scalability.
• Advanced Isolation Process: We employ either our proprietary Monocalcium Citrate process or Chromatography process, each designed to reduce sulfuric acid consumption compared to traditional methods, optimizing efficiency.
• High-Efficiency Purification: We implement specialized purification, crystallization, and anti-caking technologies for the production of both citric acid monohydrate and anhydrous citric acid.
• Citric Acid Salts Production: Our technology enables the manufacturing of various citric acid salts, including sodium, calcium, potassium, ammonium, and magnesium citrate, among others.
• Energy Efficiency: We continuously seek and implement energy-saving schemes to reduce operational costs, ensuring both profitability and sustainability.
• Water Conservation: By introducing water-saving and recycling technologies, we reduce water consumption, minimize evaporation losses, and decrease energy demand.
