Specialty Resins for Fruit Juice Processing

Fruit and vegetable juice is a popular beverage with increasing demand due to its delicious taste, diverse flavors, and beneficial health ingredients. Common fruit and vegetable juices are orange, pineapple, grape, apple, guava, and carrot. The juice production process mainly involves raw material pretreatment, juice extraction, clarification and filtration, homogenization, deoxygenation, concentration, ingredient adjustment, sterilization, and packaging.

Discoloration, poor taste and off-flavor are common problems associated with juice production, which may appear after processing or during storage. In fruit juice processing, adsorption and ion exchange resins are mainly used for deionization, decolorization, bitterness removal, and antibiotic and pesticide removal. The bitterness of grapefruit and navel orange is caused by limonin and naringin or hesperidin, respectively. This unwanted bitterness can be effectively mitigated by the selective binding of bitter compounds to the surface of the adsorbent resin. Resin-based technologies can significantly improve the sensory quality of juice without compromising its nutritional value, while extending the shelf life of the product.

SEPLITE® Adsorbent Resins for Fruit Juice Processing

Amerigo Scientific offers a variety of adsorbent resins for improving color value, light transmittance, stability, turbidity reduction, sugar-acid ratio regulation, or removal of pesticide residues, patulin, harmful ions, etc. These adsorbent resins are manufactured in accordance with U.S. Food and Drug Administration (FDA) regulations, and with the regulations of the Council of Europe Resolution AP (97) 1 on ion exchange and adsorbent resins used in the processing of foodstuffs.

SEPLITE® Ion Exchange Resins for Fruit Juice Processing

SEPLITE® LX100, LX200, and LX400 are food grade ion exchange resins with matrix structure of styrene divinylbenzene copolymers. They can be used for effective deionization of fruit juices such as apples, pears, pineapples and grapes. Their high integrity, total capacity, excellent mechanical strength, and good ion exchange dynamics make them a good general-purpose resin for different applications.
