Water-soluble Lycium barbarum polysaccharides are widely used in functional beverages and nutritional foods for their immune-modulating and antioxidant properties. Degradation of their high-molecular-weight chains during thermal processing is a critical risk. Our low-temperature vacuum extraction and multi-effect concentration systems operate under strictly regulated heating and pressure profiles, preserving native molecular weight and bioactivity. The result is a clean-label, food-grade polysaccharide extract suitable for ready-to-mix powders, energy gels, and fortified drinks.

Quercetin, sourced from sophora buds, onion skins, and apple pomace, serves a dual role as a functional supplement and a natural antioxidant for shelf-life extension. Oxidative degradation remains a key process challenge. Our enclosed solid-liquid extractors paired with inert-gas-blanketed short-path evaporators minimise oxygen ingress, achieving high-purity quercetin concentrates. These extracts can be directly applied as natural preservatives in oils, baked goods, and meat products, meeting both labelling and performance requirements.

Propolis provides potent antimicrobial and antioxidant activity, making it valuable for edible films, oral care products, and natural food preservation systems. Raw propolis, however, contains significant wax and debris. Our multi-stage filtration and low-temperature ethanol extraction lines remove inert matter while retaining key flavonoids and phenolic acids. Fully CIP-compatible and constructed from food-grade stainless steel, the system delivers a standardised, food-compatible propolis extract ready for confectionery, sprays, and active packaging.

Citrus, mint, rosemary, and oregano essential oils are integrated into foods for flavour, antimicrobial effects, and oxidative stability. To capture the complete volatile profile without thermal damage, our steam distillation and supercritical fluid extraction units apply precise temperature ramping and vacuum pressure stripping. The all-stainless-steel construction with traceable batch controls guarantees food-grade purity. Rosemary and oregano oils, in particular, are utilised as clean-label antioxidants in meat snacks and sauces, while citrus oils boost aroma in beverages and confectionery.
