Farm Fresh selects NX Filtration technology for premium tea beverage production

Farm Fresh has chosen NX Filtration’s hollow fiber microfiltration (MF) membranes for its new premium tea beverage production line. The membrane technology was delivered by original equipment manufacturer (OEM) partner Suzhou Mopu Environment, which integrated the filtration modules directly into its T-CLEAR tea clarification system.

Beverage Clarification and Flavor Retention
The transition toward premium, natural consumer beverages requires filtration technologies that provide product clarity while keeping baseline manufacturing lines efficient. NX Filtration’s hollow fiber membranes address these processing constraints by targeting and extracting haze-forming compounds, including naturally occurring pectins, colloids, and proteins.

By utilizing size exclusion rather than chemical additives, the microfiltration process clarifies the fluid while preserving critical tea polyphenols, color profiles, and natural aromatic compounds. This yields a clear tea beverage with consistent quality metrics, extended product shelf life, and a natural flavor profile. The deployment serves as an application of the company's microfiltration technology within the global food and beverage sector, where hollow fiber architectures are increasingly utilized for low-shear beverage clarification and gentle product separation.

Strategic Market Positioning
Rob Slater, Sales Director F&B of NX Filtration, stated that the project demonstrates how advanced membrane filtration assists beverage producers in elevating product quality metrics while preserving the organic characteristics most valued by consumers. Slater noted that the collaboration with Mopu Environment provides Farm Fresh with a reliable filtration platform tailored for premium beverage standards. The project represents an expansion of membrane-based clarification technologies within Asia’s expanding tea beverage market, strengthening the technology vendor's position across specialty food and beverage manufacturing applications.

Additional Context

The clarification of botanical extracts involves removing high-molecular-weight compounds that create "tea cream" suspensions as brewed tea cools. When temperature drops, polyphenols naturally complex with proteins and caffeine through hydrogen bonding, forming colloidal haze and sediment. While conventional configurations rely on diatomaceous earth or chemical fining agents that generate solid waste and strip flavor, cross-flow hollow fiber microfiltration provides physical separation without additives.

The system utilizes asymmetrical, hydrophilic PolyEtherSophone (PES) membrane fibers configured for inside-out operation. Engineered with a nominal pore size ranging from 100 to 500 nanometers, the membrane blocks turbidity-causing pectins, micro-colloids, and microbial cells while letting low-molecular-weight tea monomers and aromatic oils pass unhindered. The PES polymer structure supports mechanical stability at temperatures up to 80°C, enabling high-temperature cleaning-in-place cycles across a wide pH range to remove organic fouling layers.
