Membrane Filtration for Roxburgh Rose (Cili) Juice Clarification

Roxburgh rose juice, also known as Cili juice, is famous for ultra-high vitamin C and rich bioactive antioxidants. However, raw squeezed cili juice contains large amounts of pectin, fine pulp fibres, colloids and suspended precipitates. These impurities easily cause turbidity, sedimentation and dark colour after bottling, which greatly limits the commercial value of finished beverages, extracts and concentrated juice products. Traditional clarification methods such as diatomaceous earth filtration, centrifugation and chemical flocculation have obvious drawbacks: high nutrient loss, extra additive residues, complicated operation and unstable clarity during shelf storage.

Hollow fiber ultrafiltration membrane filtration offers an ideal low-temperature physical clarification solution for cili juice processing. Operating under mild ambient temperature without heating or chemical clarifying agents, the membrane system effectively intercepts pectin, solid precipitates, colloids and microbes while letting small molecular nutrients including VC, polyphenols and SOD pass through smoothly. After membrane treatment, cili juice maintains bright, transparent colour, natural flavour and maximum retention of functional active substances. It prevents secondary haze and precipitation during storage, extending the product shelf life significantly.

Our cross-flow hollow fiber membrane equipment is specially customized for botanical liquid processing. Compared with dead-end filtration, cross-flow design reduces membrane fouling, keeps stable flux and supports automatic CIP cleaning for continuous batch production. The whole set system features compact layout, easy maintenance and low running cost. It can be applied in raw cili juice clarification, cili extract purification and concentration. This membrane technology is widely adopted in fruit juice, plant extract and wine industries, compatible with small pilot test and large-scale industrial production.

For beverage and natural ingredient manufacturers, choosing membrane filtration helps upgrade product quality, reduce waste rate and meet strict export food safety standards. If you are facing problems such as cloudy cili juice, easy precipitation and colour darkening, our membrane separation system provides reliable and economical technical support for your cili juice clarification project.
