Method for removing bitter taste of lemon juice with macroporous resin

The invention discloses a method for removing the bitter taste of lemon juice with a macroporous resin, belonging to the technical field of drink preparation. The method comprises the following steps: selecting ripe and undamaged fresh lemons and washing, peeling and juicing the fresh lemons and filtering the juice to obtain the lemon juice; deactivating the enzyme of the lemon juice at 85-95 DEG C for 8-15 minutes and cooling the lemon juice; soaking the macroporous resin LS-803C in absolute ethyl alcohol, washing the macroporous resin LS-803C with an acid and an alkali and removing the impurities and then packing a column with the macroporous resin LS-803C; and passing the treated lemon juice through a resin column with height-diameter ratio of (5:1)-(20:1) at a flow rate of 2-11BV/h at a room temperature of 20 DEG C, thus obtaining the debitterized lemon juice. The method has the beneficial effects that the rates of removal of bitter substances in the lemon juice, especially naringin and limonin are respectively higher than 90% and 60%; the used resin can be reused, so that the processing cost is relatively low and the method is convenient to operate; the two bitter substances, namely naringin and limonin adsorbed by the resin can be further separated, purified and recycled.
