We investigated the effects of ultra filtration (UF) of Goroshoe (Acer mono Max.) sap collected in March and April. The total bacteria and turbidity of the sap collected in April were higher than in March. However, after UF, the turbidity decreased and bacteria were not detected. The total acidity and total sugar of the sap collected in April were lower than that collected in March. After UF, total acidity and total sugar decreased slightly in sap from both of the collection times. The crude

In particular, the calcium and potassium content of the sap collected in April were 166.38 and 29.47 mg/L, respectively, which was much higher than in March. Again, after UF, the crude ash and mineral content were decreased in the sap from both collection times. We concluded that UF of Goroshoe sap increased its quality regardless of collection time.
