4. Product Application
FD300 resin is mainly suitable for:
- Removing patulin, pesticides, and other residues from fruit juice, deacidification;
- Improving color value, light transmittance, and enhancing color stability;
- Decolorizing beer fermentation broth.
5. Resin Pretreatment
- Add 1/3 to 1/2 of pure water or softened water to the exchange column, load the resin into the column, ensuring no air bubbles in the resin layer.
- Pass 2-3% sodium hydroxide solution through the resin layer at a flow rate of 1-2 BV, for about 1-2 hours (15-20 minutes under experimental conditions). The effluent being alkaline indicates sufficient alkali.
- Rinse with pure water until the effluent pH is below 8.
- Pass 2-3% hydrochloric acid through the resin layer at a flow rate of 1-2 BV for about half an hour for conversion. The effluent being acidic indicates sufficient acid.
- Rinse with pure water or softened water until the pH is near neutral, then it is ready for use.
